How Long Does It Take to Recover from an LCL Tear? Grades, Treatment and Recovery

A knee injury can affect your ability to walk, climb stairs, exercise and perform everyday activities. One such injury is a lateral collateral ligament (LCL) tear, which affects the ligament located on the outer side of the knee.



The LCL helps stabilise the knee joint by connecting the thigh bone (femur) to the smaller bone of the lower leg (fibula). It provides support during movements and helps prevent excessive sideways movement of the knee.

An LCL injury may occur during sports, falls, road accidents or activities that place sudden stress on the outer side of the knee. Recovery time depends on the severity of the tear, associated injuries and the individual's response to treatment.

Understanding the symptoms, treatment options and LCL tear recovery time can help you take appropriate steps towards recovery.

What Are the Common Symptoms of an LCL Tear?

The symptoms of a lateral collateral ligament injury may vary depending on whether the ligament is mildly stretched or completely torn.

Common symptoms include:

  • Pain on the outer side of the knee: Discomfort may increase while walking, bending or putting weight on the affected leg.

  • Swelling and bruising: Swelling may develop around the knee following the injury.

  • Knee instability: The knee may feel weak or as though it could give way during movement.

  • Difficulty walking: Pain and instability can make standing or bearing weight difficult.

  • Restricted movement: Bending or straightening the knee may become uncomfortable.

  • Tenderness: The outer part of the knee may feel painful when touched.

If you experience these symptoms after an injury, consult an orthopedic surgeon for an examination. Severe pain, significant swelling or an inability to bear weight requires prompt medical assessment.

How Is an LCL Tear Diagnosed?

An orthopedic surgeon evaluates the injury to determine its severity and check for damage to other structures in the knee.

The assessment may include:

1. Physical examination: The doctor checks the location of pain, swelling, knee movement and ligament stability.

2. X-ray: An X-ray may be recommended to identify fractures or injuries involving the bones around the knee.

3. MRI scan: Magnetic resonance imaging can help assess the LCL and identify associated injuries involving other ligaments, cartilage or surrounding tissues.

An accurate diagnosis helps determine whether non-surgical treatment or surgery may be appropriate.

How Are LCL Tears Treated?

Treatment for an LCL tear depends on the grade of injury, knee stability and whether other structures have been damaged.

1. Non-Surgical Treatment

Many isolated LCL injuries, particularly mild and moderate tears, may be managed without surgery.

Treatment may include:

  • Rest and activity modification: Avoid activities that increase knee pain or place stress on the injured ligament.

  • Ice application: Applying an ice pack wrapped in a cloth for short intervals may help manage swelling and discomfort.

  • Compression and elevation: Suitable compression and elevating the leg may help reduce swelling.

  • Knee bracing: A doctor may recommend a brace to support the knee and limit unwanted movement.

  • Medication: Appropriate pain-relief or anti-inflammatory medication may be prescribed based on individual health needs.

  • Physiotherapy: A guided rehabilitation programme helps restore knee movement, muscle strength and joint stability.

The type and duration of treatment should be determined after clinical assessment.

2. Surgical Treatment

Surgery may be considered for selected severe LCL injuries, particularly complete tears associated with significant knee instability or damage to other ligaments.

Depending on the injury, the surgeon may recommend ligament repair or reconstruction. Reconstruction involves using a tissue graft to restore the function of the damaged ligament.

The decision to perform surgery depends on factors such as injury pattern, ligament damage, knee stability and the patient's activity requirements.

How Long Does Recovery from an LCL Tear Take?

LCL tear recovery time varies depending on the severity of the injury and the treatment required. These are approximate recovery ranges, not fixed timelines.

Grade 1 LCL Tear: Mild Injury

A Grade 1 injury involves stretching or minor damage to the ligament fibres without significant instability.

  • Approximate recovery: 2–4 weeks.

  • Treatment: Activity modification, swelling management and guided exercises.

  • Focus: Reducing discomfort and gradually restoring normal knee movement.

Most people with isolated mild injuries can return to routine activities as symptoms improve.

Grade 2 LCL Tear: Moderate Injury

A Grade 2 injury involves a partial tear of the ligament and may cause noticeable pain and some knee instability.

  • Approximate recovery: 4–8 weeks or longer.

  • Treatment: Bracing when indicated, activity modification and physiotherapy.

  • Focus: Improving muscle strength, flexibility and knee stability.

Recovery may take longer if other knee structures are also affected.

Grade 3 LCL Tear: Severe Injury

A Grade 3 injury involves a complete tear of the ligament and may cause significant knee instability.

  • Approximate recovery: Several months, depending on treatment and associated injuries.

  • Treatment: Selected cases may require surgery, followed by structured rehabilitation.

  • Focus: Restoring knee stability, strength, movement and functional ability.

For severe injuries, recovery may extend beyond the initial healing period. Returning to sports or strenuous activities requires medical clearance.

What Can You Do at Home During LCL Tear Recovery?

Home care can help manage symptoms, but it should complement the treatment plan recommended by your doctor.

Some useful measures include:

Follow the RICE approach: Rest, Ice, Compression and Elevation may help manage early swelling and discomfort. Compression should not be too tight, and ice should not be applied directly to the skin.

Follow prescribed exercises: Gentle range-of-motion and strengthening exercises may be introduced at the appropriate stage of recovery.

Avoid high-impact activities: Running, jumping, sudden direction changes and sports may place additional stress on the healing ligament.

Attend physiotherapy sessions: A physiotherapist can guide exercises according to your recovery progress and help improve knee function.

Avoid starting exercises or returning to sports without professional guidance, particularly after a complete ligament tear.

What Factors Affect LCL Tear Recovery Time?

Several factors can influence how quickly an LCL injury heals:

  • Grade and extent of ligament damage.

  • Associated injuries to other knee structures.

  • Age and general health.

  • Treatment approach.

  • Consistency with prescribed rehabilitation.

  • Physical activity and sporting requirements.

Following the recommended treatment and rehabilitation programme can support recovery and help restore knee function.
