Highlights
Pain on the outer side of the knee, swelling, and joint instability are common symptoms of an LCL injury—recognizing them early helps guide treatment.
The fastest way to improve LCL injury recovery time is through a structured physical therapy plan that combines pain relief, mobility work, and muscle reactivation.
Safe rehab exercises like quad sets, leg raises, and balance drills help rebuild stability, while deep squats and lateral lunges should be avoided to prevent setbacks.
When dealing with a knee injury that affects the outer side of the joint, one of the first questions that comes up is how long healing might take. LCL injury recovery time depends on factors like the severity of the damage, the type of treatment, and how you manage movement in the weeks that follow.
In this article, you’ll learn what the lateral collateral ligament (LCL) does, how it gets injured, and which actions can support your progress—from early care to physical therapy, exercises, and prevention strategies.

Anatomy of the Lateral Collateral Ligament
The LCL is a narrow ligament located on the outer side of the knee. It connects the femur (thigh bone) to the fibula (a small bone in the lower leg). Its main role is to prevent the joint from buckling outward and to stabilize lateral motion.
This ligament is especially important for athletes because it provides essential stability during dynamic movements, such as cutting, pivoting, and sprinting.
A healthy LCL allows for better coordination and balance, which is crucial in sports that involve sudden changes in direction. An injury in this area can significantly impact performance and may lead to compensatory-related issues if not properly addressed.
How the LCL Gets Injured - LCL Injury Causes
The most common causes for LCL injury are:
Direct impact on the inner side of the knee: A blow from the inside can overload the outer ligament and lead to strain or tear.
Sudden changes in direction while running: Quick pivots or shifts place stress on the outer joint structures.
Overextension during sports: Stretching the leg beyond its natural range—whether during a fall or sudden deceleration—can compromise the ligament.
Poor mechanics during jumps: Movements like landing on one foot or rotating the knee inward increase lateral strain.
Contact injuries: Often seen in football, soccer, and rugby, where tackles or collisions force the joint out of alignment.
LCL Injury Symptoms
These are some of the symptoms you may experience if the lateral collateral ligament has been affected:
Sharp pain along the outer side of the knee.
Swelling and tenderness near the joint.
Instability or "giving way" sensation.
Stiffness and reduced range of motion.
A “popping sound” at the moment of injury.
How to Tell If Your LCL Is Torn or Sprained?
To know if you've torn or sprained your LCL, pay close attention to your symptoms:
A sprain usually means the ligament is stretched or partially torn. This often causes mild to moderate pain, tenderness on the outer side of your knee, and some difficulty moving it.
A full tear, however, leads to sharper pain, visible swelling, and a feeling that your knee is unstable or might give out. In more serious cases, you might need a brace or even surgery to fully restore knee function and stability.
LCL Injury Treatment Without Surgery
📌 Most mild to moderate LCL injuries can be treated without surgery, using a combination of early care and structured rehabilitation. |
Initial treatment often involves the RICE method: Rest, Ice, Compression, and Elevation. Resting helps prevent further strain, while ice reduces inflammation and discomfort. Compression with a bandage or brace offers support, and elevating the leg helps circulation and healing.
Physical therapy is essential for restoring strength and stability. A tailored program typically includes range-of-motion exercises, muscle activation, and balance work—adjusted to the phase of recovery and individual progress.
What Is the Fastest Way to Heal an LCL Injury?
The fastest way to heal an LCL injury is through a structured physical therapy program. Working with a licensed therapist allows for targeted pain relief, joint mobilization, and gradual strengthening tailored to your condition.
Starting early not only speeds up recovery—it also helps prevent setbacks and ensures a safer return to activity.

LCL Injury Exercises
Here are five exercises commonly used in LCL rehab:
Quad sets – Engage the quadriceps while keeping the knee stable.
Straight leg raises – Strengthen the thigh and hip without flexing the joint.
Hamstring curls – Reinforce the back of the leg to support balanced movement.
Side-lying leg lifts – Activate the outer hip and improve lateral control.
Resistance band walks – Enhance joint stability and coordination during side-to-side motion.
Incorporating these exercises consistently can speed up progress and reduce the risk of setbacks.
LCL Exercises to Avoid
While exercise plays a key role in healing, certain movements can slow progress or worsen symptoms—especially during the early stages of recovery. These are best avoided until cleared by a professional:
Deep squats
Lateral lunges
Running before regaining joint stability
Jumping or plyometric drills without supervision
Any movement that triggers discomfort, pressure, or loss of control
Steering clear of these activities allows the ligament to recover properly and reduces the risk of complications.
Prevention: How Can I Reduce My Risk of LCL Tears?
To lower your chances of a future LCL injury, it’s important to build strength, control, and smart movement habits. Here are some effective ways to reduce your risk:
Warm up thoroughly before any workout.
Strengthen supporting muscles like the glutes, quads, and hamstrings.
Focus on technique during agility and jumping exercises.
Add balance and proprioception drills to your routine.
Choose footwear that matches your activity and surface.
These simple strategies can make a big difference in long-term joint stability and performance.
FAQs About LCL Injury Recovery
Can a LCL Tear Heal on Its Own?
Yes, LCL tear can heal on its own if it’s mild and located in a well-vascularized area. Rest, bracing, and physical therapy are usually enough for recovery. Complete tears, however, often require surgery and a more intensive rehab plan.
Is It Ok to Walk on a Torn LCL?
No, it’s not okay to walk on a torn LCL without medical clearance. Putting weight on the joint too soon can increase instability, delay healing, or worsen the damage. Use a brace and follow professional guidance before resuming activity.
Can You Bend Your Knee with a LCL Tear?
Yes, you can bend your knee with an LCL tear, but the range of motion may be limited depending on the severity.
