LCL Injury – Causes, Symptoms, Diagnosis, Treatment

LCL Injury – Causes, Symptoms, Diagnosis, Treatment

LCL Injury/Lateral Collateral Ligament Injury is the primary varus stabilizer of the tibiofemoral joint. Diagnosing an injury to this ligament can be challenging in the setting of multi ligamentous trauma; however, failure to recognize these injuries can result in instability of the knee and unsatisfactory outcomes after cruciate ligament reconstruction. Recent literature exploring the anatomy and biomechanics of the lateral collateral ligament has enhanced our understanding and improved diagnosis and management of these injuries.

Lateral collateral ligament (LCL) sprain occurs when the ligament on the outer side of the knee is overstretched. LCL sprains mainly happen during sporting activities, including contact and non-contact sports, and affect women and men equally. A physical therapist treats LCL sprains to reduce pain, swelling, stiffness, and any associated weakness in the knee or lower extremity.

The lateral collateral ligament (LCL) is one of four critical ligaments involved in stabilizing the knee joint. Stabilizing the knee on the outside, or lateral side, of the joint, it extends from the top-outside surface of the fibula, the bone on the outside of the lower leg, to the bottom-outside surface of the femur, the thigh bone. A lateral collateral ligament injury involves a stretch, partial tear, or complete tear of this particular knee ligament. In some instances, the injury is significant enough to cause an avulsion fracture of the fibular head (out top area of the shin bone).

Types of  Lateral Collateral Ligament Injury

The lateral collateral ligament injury may be classified as follows

  • Grade 1 — Some tenderness and minor pain at the point of the injury. This means there have been small tears in the ligament.
  • Grade 2 — Noticeable looseness in the knee (the knee opens up about 5 millimeters) when moved by hand. There is a major pain, tenderness, and swelling on the inner side of the knee. This means there have been larger tears in the ligament, but it is not completely torn.
  • Grade 3 — Considerable pain and tenderness at the inner side of the knee; some swelling and marked joint instability. The knee opens up slightly less than half an inch when moved. A grade 3 LCL tear means the ligament is completely torn. There may also be a tear of the anterior cruciate ligament.

Causes of Lateral Collateral Ligament Injury

LCL tears are commonly seen in contact sports or activities that involve twisting and heavy lifting. They can occur in the following instances

  • When the inside (medial side) of the knee is hit directly – such as during soccer or a football tackle, putting extra stress on the LCL on the outside (lateral side) the knee
  • Quickly changing directions – such as cutting or pivoting maneuvers, which puts unusual pressure on the knee causing the ligament to stretch or tear
  • Landing awkwardly on the knee – which may happen after a jump in volleyball or basketball
  • Hyperextending the knee – which is caused when the joint is pushed passed its normal range of motion either forwards or backward
  • Squatting or lifting heavy objects – such as during weightlifting or in physical occupations.
  • Motor vehicle accidents – A dashboard injury occurs when the driver’s or passenger’s bent knee slams against the dashboard, pushing in the shinbone just below the knee and causing a tear.
  • Contact sports – Athletes in sports such as football and soccer can tear their ligament when they fall on a bent knee with their foot pointed down. The shinbone hits the ground first and it moves backward. Being tackled when your knee is bent also can cause this injury.
  • The knee is hit directly – especially during sports like soccer, rugby, and football
  • A person lands on a bent knee – such as during a fall or misstep
  • Landing directly on the front of the shinbone – such as when a dancer comes down from a leap and falls
  • A person makes cutting or pivoting maneuvers – such as when an athlete plants a foot and shifts directions
  • A person lands on one leg – which can happen after a jump in basketball or volleyball
  • A direct blow to the bent knee in an automobile injury
  • A sports-related injury in which the knee bends
  • Pulling on the ligament in a twisting injury or hyperextension
  • A misstep on uneven terrain
  • When the knee is hit directly on its outer side, such as from a football tackle
  • As a result of cutting maneuvers, when an athlete plants a foot and forcefully shifts direction

Symptoms of Lateral Collateral Ligament Injury

People with knee lateral collateral ligament (LCL) injuries often report a combination of the following symptoms:

  • Pain along the outside of the knee – This can be mild to severe depending on the severity of the tear. Pain and swelling on the outside or posterolateral aspect of the knee
  • Tenderness – The outside of the knee may be painful to the touch.
  • Swelling along the outside of the knee – This can happen immediately following the injury or develop up to 2 or 3 hours after it occurred. Swelling and tenderness along the outside of the knee
  • Decreased range of motion – Certain movements, such as bending at the knee, may be difficult.
  • Knee catching or locking – The knee may feel like it gets stuck during movement; a person may have difficulty fully bending or extending the knee.
  • Bruising – Some people may experience bruising around the outside of the knee, which is caused by tiny blood vessel tears under the skin.
  • Trouble bearing weight – Depending on the severity of the injury, a person may have difficulty bearing weight on the affected leg, such as when standing and walking. People with more severe tears may develop instability and feel as if the knee is going to buckle or give way.
  • Foot numbness – A person may experience foot numbness if the peroneal nerve, located near the LCL, is stretched during the injury or affected by tissue swelling. Numbness or weakness in the foot may occur if the peroneal nerve, which is near the ligament is stretched during the injury or is pressed by swelling in surrounding tissues.
  • Pain with walking or bending the knee
  • Feelings of instability (knee giving out) while walking or doing an activity
  • Mechanical symptoms (locking, catching) may indicate associated meniscus injury
  • A feeling that the knee may give way under stress and isn’t stable
  • A locking or catching in the joint when it is moved
  • Pain that can be mild or acute
  • Stiffness

Diagnosis of Lateral Collateral Ligament Injury

Physical Exam

Testing of the knee joint should be done using the following techniques and the findings compared to the contralateral, normal knee:[rx][rx]

  • Valgus stress at 0° and 20° – This test puts direct stress on the medial knee structures, reproducing the mechanism of injury. Valgus stress testing is done with the patient supine on the exam table. The lower extremity, supported by the examiner, is abducted. The examiner’s fingers monitor the medial joint space for gapping while placing the opposite hand on the ankle. The knee is placed in 20° of flexion. The examiner then uses their own thigh as a fulcrum at the knee and applies a valgus force (pulling the foot and ankle away from the patient’s body). The force is then used to establish the amount of gapping present within the joint. It has been reported that 20° of flexion is best for isolating the MCL, allowing the practitioner to establish the degree of injury (see Classification). Additional testing is done at 0° to determine if a Grade III injury is present.[rx][rx]
  • Valgus stress testing –  is the best way to test the integrity of the MCL directly. The patient should be positioned supine with the hip abducted on the affected side so that the leg is unsupported off the table. The knee should be brought into 30 degrees of flexion. The examiner should grasp the ankle with one hand and push the ankle laterally while applying a valgus force to the knee with the other hand.
  • Anteromedial drawer test – This test is performed with the patient supine with the knee flexed to 80-90°. The foot is externally rotated 10-15° and the examiner supplies an anterior and external rotational force. The joint can then be evaluated for tibial anteromedial rotation, taking care to recognize the possibility of posterolateral corner instability giving similar rotational test results. As always, compare the test in the opposite knee.[rx][rx][rx]
  • Dial Test (anteromedial rotation test) – This test should be executed with the patient lying both supine and prone. When the patient is supine, the knees must be flexed 30° off the table. The thigh is then stabilized and the foot externally rotated. The examiner watches for the tibial tubercle of the affected knee to rotate as the foot rotates, comparing it to the contralateral knee. A positive test will show the rotation of greater than 10-15° of rotation compared to the opposite knee. This is most easily assessed with a hand placed over the tibia while testing. When the patient is prone, the knee is flexed to 90° and both feet are externally rotated and compared, noting the difference from the non-injured joint. Similar to the anteromedial drawer test, a false positive test can result from a posterolateral corner injury. Testing at both 30° and 90° helps to distinguish between these injuries: one should monitor where the tibial rotation occurs (anteromedial or posterolateral) in the supine position and also assess for medial or lateral joint line gapping to differentiate between these two injuries.[rx][rx][rx]

Imaging Test

  • X-rays – use low levels of radiation and give doctors a view of a person’s bones. Although LCL injuries do not show up on standard X-ray exams, they are a relatively inexpensive, fast way to rule out other possible injuries that might be causing the symptoms. Additionally, a stress X-ray—where a physician applies a valgus force to the knee during the exam—can help to determine the degree of ligamentous injury.
  • Magnetic resonance imaging (MRI) – shows a detailed view of the soft tissue surrounding the knee joint. An MRI can also help a doctor determine the location and grade of an LCL tear.
  • Ultrasound imaging – uses high-frequency sound waves to build a picture of the knee’s tissues. Ultrasound can be utilized in situations when an MRI is not recommended. Ultrasound may also be used in an urgent care setting to make an immediate assessment, allowing the injury to be treated more quickly.

Treatment of Lateral Collateral Ligament Injury

Immediately following the injury, the RICE method is recommended

  • Rest – Activities that cause knee pain, such as running or walking for long periods of time, should be avoided until pain and swelling go away. The activity that caused the injury should be avoided until fully recovered.
  • Ice – A person may wish to apply ice packs to the area to help reduce pain and swelling. Ice packs can be applied several times throughout the day for about 10 to 20 minutes at a time.
  • Compression – Swelling can be managed by wearing an elastic bandage around the affected knee.
  • Elevation – Keeping the knee elevated and supported above the waist—for example, sitting in a recliner or lying down with the knee propped up on pillows—may help with swelling.
  • Wear a knee cap – that allows the knee to move forward and backward but restricts side-to-side movement. Apply minimally restrictive lateral hinge brace (grade II or III injuries).
  • Use crutches – to avoid weight-bearing. Crutches are not needed in all cases. Dispense crutches; allow weight-bearing as tolerated.
  • Bracing – Your knee must be protected from the same sideways force that caused the injury. You may need to change your daily activities to avoid risky movements. Your doctor may recommend a brace to protect the injured ligament from stress. To further protect your knee, you may be given crutches to keep you from putting weight on you.

Physiotherapy

  • Reduce Pain and Swelling – Your physical therapist may use different types of treatments and technologies to control and reduce your pain and swelling, including ice, heat, ultrasound, electrical stimulation, taping, exercises, and hands-on therapy, such as massage.
  • Improve Motion – Your physical therapist will choose specific activities and treatments to help restore normal movement in the knee and leg. These might begin with “passive” motions that your physical therapist performs for you to gently move your leg and knee joint, and progress to active exercises and stretches that you do yourself.
  • Improve Flexibility – Your physical therapist will determine if any of your leg muscles are tight, and teach you how to stretch them.
  • Improve Strength – Certain exercises will aid healing at each stage of recovery. Your physical therapist will choose the exercises and equipment that are right for your specific condition to steadily restore your strength and agility. These may include cuff weights, stretch bands, weight-lifting equipment, and cardio exercise equipment, such as treadmills or stationary bicycles.
  • Improve Balance and Agility – Regaining your sense of balance is important after an injury. For athletes, restoring agility is important, also. Your physical therapist will teach you exercises to improve your balance and agility skills.
  • Speed Recovery Time – Your physical therapist is trained and experienced in choosing the best treatments and exercises to help you heal, return to your normal lifestyle, and reach your goals faster than you are likely to do on your own.
  • Return to Activities – Your physical therapist will discuss your goals with you and use them to set your work, sport, and home-life recovery goals. Your treatment program will help you reach those goals in the safest, fastest, and most effective way possible. Your physical therapist will teach you exercises, work retraining activities, and sport-specific techniques and drills to help you achieve your goals.

Medication

If the injury is severe and pain is intolerable the following medicine can be considered to prescribe

  • Take anti-inflammatory medications – Non-steroidal anti-inflammatory drugs (NSAIDs), like will help with pain and swelling. However, these drugs can have side effects, such as an increased risk of bleeding and ulcers. They should be only used occasionally unless your doctor specifically says otherwise.
  • Antibiotic – Cefuroxime or Azithromycin, or  Flucloxacillin or any other cephalosporin/quinolone antibiotic must be used to prevent infection or clotted blood remove to prevent furthers swelling and edema.
  • NSAIDs – Prescription-strength drugs that reduce both pain and inflammation. Pain medicines and anti-inflammatory drugs help to relieve pain and stiffness, allowing for increased mobility and exercise. There are many common over-the-counter medicines called non-steroidal anti-inflammatory drugs (NSAIDs). They include and KetorolacAceclofenacNaproxen, Etoricoxib.
  • Corticosteroids – Also known as oral steroids, these medications reduce inflammation.
  • Muscle Relaxants –  These medications provide relief from associated muscle spasms.
  • Neuropathic Agents – Drugs(pregabalin & gabapentin) that address neuropathic—or nerve-related—pain. This includes burning, numbness, and tingling.
  • Opioids – Also known as narcotics, these medications are intense pain relievers that should only be used under a doctor’s careful supervision.
  • Topical Medications – These prescription-strength creams, gels, ointments, patches, and sprays help relieve pain and inflammation through the skin.
  • Calcium & vitamin D3 – to improve bone health and healing fracture. As a general rule, men and women age 50 and older should consume 1,200 milligrams of calcium a day, and 600 international units of vitamin D a day.
  • Antidepressants – A drug that blocks pain messages from your brain and boosts the effects of endorphins (your body’s natural painkillers).
  • Glucosamine & DiacereinChondroitin sulfate – can be used to tightening the loose tension, cartilage, ligament, and cartilage, ligament regenerates cartilage or inhabits the further degeneration of cartilage, ligament. They are structural components of articular cartilage, and the thought is that a supplement will aid in the health of articular cartilage.
  • Intra-articular corticosteroid injections – may be useful for symptomatic injury especially where there is a considerable inflammatory component. The delivery of the corticosteroid directly into the knee may reduce local inflammation associated with injury and minimize the systemic effects of the steroid.
  • Intra-articular hyaluronic acid injections (HA) – injections are another injectable option for a knee injury. HA is a glycosaminoglycan that is found throughout the human body and is an important component of synovial fluid and articular cartilage. HA breaks down during the process of ligament injury and contributes to the loss of articular cartilage as well as stiffness and pain. Local delivery of HA into the joint acts as a lubricant and may help increase the natural production of HA in the joint.
  • Platelet-rich plasma (PRP) injection – newer therapy where a blood sample is taken from the patient, spun in a centrifuge, growth factors are isolated and then they are injected back into the affected site to stimulate faster healing.

Surgery

If your LCL tore all the way through, you may need to have surgery to repair it. Athletes who want to play sports again may opt for surgery, for instance.

  • The surgeon may stitch up your torn LCL or attach it to the bone where it tore. It depends on how you damaged your ligament. LCL surgery is an “open-knee procedure,” which means the surgeon can’t work through smaller arthroscopic cuts, as with some other types of knee surgery.

Rehabilitation

The rehabilitation for a non-operative treatment can be split into four phases:

  • Phase one –  is from one to two weeks. Phase one consists of controlling the swelling of the knee by applying ice for 15 minutes every two hours (first two days). The rest of the week the frequency can be reduced to three times a day. Use ice as tolerated and as needed based on symptoms. In the beginning, the patient needs to use crutches. Early weight bearing is encouraged because patients who increasing their weight-bearing, they can progressively reduce their dependence on crutches. Afterward, progress to one crutch and let the patient stop using the crutches only when normal gait is possible. Another aim of this phase is to try to maintain the ability to straighten and bend the knee from 0° to 90° knee flexion. For achieving the range of motion of the knee it is important to emphasize full extension and progress flexion as tolerated. Pain-free stretches for the hamstrings, quads, groin and calf muscles (in particular) are suggested. At last, there are therapeutic exercises. The patient may begin with static strengthening exercises (as soon as pain allows it). They consist for example of Quadricpes sets, straight leg raises, range-of-motion exercises, sitting hip flexion, side-lying hip abduction, standing hip extension, standing, and hamstring curls. As soon as patients can tolerate it, they are encouraged to ride a stationary bike to improve the range of motion of the knee. This would ensure accelerated healing. The amount of time and effort on the stationary bike is increased as tolerated. Obviously, every patient is different and these are not the standard exercises that have to be given to patients. There are no limits on upper extremity workouts that do not affect the injured knee[rx]. It’s important that the patient rests from all painful activities (use crutches if necessary), and that the MCL is well protected (by wearing a stabilized knee brace).
  • Starting at week three-phase two begins – The aims for the range of motion are the same as in phase one. Progress to 20 minutes of biking. Increase also the resistance as tolerated by the patient. Biking will ensure healing, rebuild strength, and maintain aerobic conditioning. The physiotherapist can give other exercises like Hamstring curls, leg presses (double-leg), and step-ups. As a precaution, the patient has the chance to be examined by a physician every three weeks to verify the healing of the ligament[rx].
  • Phase three starts from week five –  A major goal for this phase: full weight-bearing on the injured knee. Discontinue the use of a brace when ambulating with full weight-bearing is possible and there is no gait deviation. The range of motion has to be fully achieved and had to be symmetrical with the not injured knee. The therapeutic exercises are the same as in phase two. They may benefit progression. We continue with cold therapy and compression to eliminate swelling. In this phase, you can commence with balance and proprioceptive activities. To maintain aerobic fitness the patient can use the stepper or (if possible) may begin to swim. As a precaution, the patient has the chance to be examined by a physician every five to six weeks. When needed, you can be allowed to make stress radiography as a precaution.[rx]
  • Six weeks after injuring the knee, phase four can begin – Discontinue wearing the brace during the gait. Athletics can wear the brace for competition through the competitive season for at least three months. Cold therapy still needs to be applied. The aim of the therapeutic exercises is more focused on sport-specific or daily movements. The intensity of the strengthening exercises needs to be increased and instead of double leg exercises, we change to single-leg exercises. The patient may start running again at a comfortable pace (make sure the patient doesn’t make sudden changes of direction). As a precaution, it is best to return the competition once full motion and strength is returned and when the patient passes a sport functional test[rx].

How Do I Get Ready For A Knee Ligament Repair?

  • Your healthcare provider will explain the procedure to you and offer you the chance to ask any questions that you might have about the procedure.
  • You will be asked to sign a consent form that gives your permission to do the procedure. Read the form carefully and ask questions if something is not clear.
  • In addition to complete medical history, your healthcare provider may perform a complete physical exam to ensure you are in good health before undergoing the procedure. You may undergo blood tests or other diagnostic tests.
  • Tell your healthcare provider if you are sensitive to or are allergic to any medicines, latex, tape, and anesthetic agents (local and general).
  • Tell your healthcare provider of all medicines (prescribed and over-the-counter) and herbal supplements that you are taking.
  • Tell your healthcare provider if you have a history of bleeding disorders or if you are taking any anticoagulant (blood-thinning) medicines, aspirin, or other medicines that affect blood clotting. It may be necessary for you to stop these medicines before the procedure.
  • If you are pregnant or suspect that you are pregnant, you should notify your healthcare provider.
  • You will be asked to fast for 8 hours before the procedure, generally after midnight.
  • You may receive a sedative prior to the procedure to help you relax. Because the sedative may make you drowsy, you will need to arrange for someone to drive you home.
  • You may meet with a physical therapist prior to your surgery to discuss rehabilitation.
  • Arrange for someone to help around the house for a week or two after you are discharged from the hospital.
  • Based on your health condition, your healthcare provider may request other specific preparations.

What Happens During A Knee Ligament Repair?

Knee ligament repair may be done on an outpatient basis or rarely as part of your stay in a hospital. Procedures may vary depending on your condition and your healthcare provider’s practices.

Knee ligament repair may be performed while you are asleep under general anesthesia, or while you are awake under spinal anesthesia. If spinal anesthesia is used, you will have no feeling from your waist down. Your healthcare provider will discuss this with you in advance.

Generally, knee ligament repair surgery follows this process

  • You will be asked to remove clothing and will be given a gown to wear.
  • An intravenous (IV) line may be started in your arm or hand.
  • You will be positioned on the operating table.
  • The anesthesiologist will continuously monitor your heart rate, blood pressure, breathing, and blood oxygen level during the surgery.
  • The skin over the surgical site will be cleansed with an antiseptic solution.
  • The healthcare provider will make several small incisions in the knee area.
  • The healthcare provider will do the surgery using an arthroscope (a small tube-shaped instrument that is inserted into a joint). The healthcare provider may reattach the torn ligament or reconstruct the torn ligament by using a portion (graft) of the patellar tendon (that connects the kneecap to the tibia), the hamstring tendon (from the back of the thigh), or other autografts. The tendon graft may come from the person (autograft) or from an organ donor (allograft).
  • The healthcare provider will drill small holes in the tibia and femur where the torn ligament was attached.
  • The healthcare provider will thread the graft through the holes and attach it with surgical staples, screws, or other
    means. Bone eventually grows around the graft.
  • The incision will be closed with stitches or surgical staples.
  • A sterile bandage or dressing will be applied.

What Happens After A Knee Ligament Repair?

After the surgery, you will be taken to the recovery room for observation. Your recovery process will vary depending on the type of anesthesia that is given. Once your blood pressure, pulse, and breathing are stable and you are alert, you will be taken to your hospital room or discharged to your home. Knee ligament repair is usually done on an outpatient basis.

You may be given crutches and a knee immobilizer before you go home.

Once you are home, it is important to keep the surgical area clean and dry. Your healthcare provider will give you specific bathing instructions. The stitches or surgical staples will be removed during a follow-up office visit.

Take a pain reliever for soreness as recommended by your healthcare provider. Aspirin or certain other pain medicines may increase the chance of bleeding. Be sure to take only recommended medicines.

To help reduce swelling, you may be asked to elevate your leg and apply an ice bag to the knee several times per day for the first few days. Your healthcare provider will arrange for an exercise program to help you regain muscle strength, stability, and range of motion. Physical therapy is a key part of recovery.

Tell your healthcare provider if you have any of the following:

  • Fever or chills
  • Redness, swelling, bleeding, or another drainage from the incision site
  • Increased pain around the incision site
  • Numbness or tingling in the leg
  • Calf swelling or tenderness

You may resume your normal diet unless your healthcare provider advises you differently.

Because of the limited mobility, it may be hard for a few weeks to resume your normal daily activities. You may need someone at home to assist you. You should not drive until your healthcare provider tells you to. Other activity restrictions may apply. Full recovery from the surgery and rehab may take several months.

Your healthcare provider may give you additional or alternate instructions after the procedure, depending on your particular situation.
