Is LCL Surgery Needed After a Sports Injury?
Yes, LCL surgery is often considered after a sports injury when the ligament is fully torn or the knee lacks stability. In such cases, surgical treatment helps restore stability, especially when other knee ligaments like the anterior cruciate ligament or medial collateral ligament are also damaged. For less severe LCL injuries, non-surgical treatment such as a knee brace and pain medication is often effective.
Ongoing knee pain after a sports injury can limit your movement and lead to further injury, especially if you have a torn LCL. Without proper treatment, the joint may become unstable. At Total Orthopedics & Sports Medicine, our team treats all types of ligament injuries, offering non-surgical treatments and LCL reconstruction surgery. Our advanced orthopedic care supports accurate diagnosis and long-term recovery. Contact us at 855-321-6784 today to begin your recovery.
When Should You Get LCL Surgery After a Sports Injury?
If your knee remains unstable after a sports injury despite using a knee brace, pain medication, or other non-surgical treatment, you should get LCL surgery. Ongoing joint weakness or delayed healing may also show a torn LCL, often requiring surgical repair to restore proper knee function.
If the injury affects more than just the lateral collateral ligament, surgery often becomes a necessary step to protect overall knee function. According to ScienceDirect, early anatomic reconstruction (a type of LCL surgery) is typically recommended for Grade III LCL tears, especially when there’s posterolateral corner injury, peroneal nerve involvement, or damage to multiple knee ligaments.
Your orthopedic specialist may use a varus stress test to confirm the severity. If the outside of your knee opens more than 4 mm, it often signals a complete tear that won’t heal without surgery. Timely LCL surgery helps protect the knee joint, reduce strain on nearby structures, and lower the risk of chronic instability or further injury.
What Causes Knee Injuries in Athletes?
You can injure your knee during sports from a direct blow, sudden twisting, awkward landings, or quick changes in direction. These movements place high stress on your knee ligaments, especially the lateral collateral ligament (LCL), anterior cruciate ligament, and medial collateral ligament. In some cases, overuse, poor conditioning, or improper technique can also lead to a torn ligament, swelling, and long-term joint damage.
Beyond sudden movements, several other factors increase your risk of sports-related knee injuries:
- Muscle fatigue reduces joint support and raises the risk of a torn ligament.
- A prior knee injury nearly doubles your chance of reinjury within a year.
- Female athletes face a higher risk due to joint laxity and muscle control differences.
- Synthetic turf increases the rate of non-contact lower-leg injuries compared to grass.
To reduce these risks, sports medicine experts recommend neuromuscular training programs that improve strength, agility, and landing control. According to ScienceDirect, these programs have been shown to lower knee injury risk by 50-70 percent.
Which Surgical Options are Available for Ligament Injuries?
At Total Orthopedics & Sports Medicine, we offer several surgical options to treat ligament injuries and restore knee stability. These include arthroscopic ACL, MCL, and PCL reconstruction, MPFL reconstruction, and arthroscopic meniscectomy. When cartilage is damaged, microfracture surgery may help stimulate healing. For advanced joint damage, we may recommend partial or total knee arthroplasty to improve mobility and long-term joint function..
For complete LCL tears, our orthopedic surgeons typically consider the following techniques:
Repair with Internal Brace
If your tear is recent (within 1–3 weeks) and located at the ligament’s attachment site, your surgeon may recommend a minimally invasive repair. In this approach, the torn ligament is reattached and reinforced using a strong suture tape called an Internal Brace. This added support allows for early motion and has shown better outcomes than traditional repair alone.
Reconstruction with Tendon Graft
If the tear is chronic or occurs in the middle of the ligament (mid-substance), surgeons typically recommend anatomic reconstruction. In this procedure, the damaged ligament is replaced with a tendon graft, often taken from your hamstring or Achilles tendon. According to Arthroscopy Techniques, reconstruction has a significantly lower failure rate, about 9% compared to 37% for repairs in similar injuries.
Peroneal Nerve Neurolysis
If your knee injury involves nearby ligaments and leads to symptoms like numbness or foot drop, your surgeon may also perform peroneal nerve neurolysis. This procedure helps relieve pressure around the nerve. In more severe cases, they may add nerve grafting or perform a separate nerve repair during the same surgery to restore function and prevent long-term nerve damage.
How Do Doctors Decide Between LCL Repair vs. Reconstruction?
If your tear is diagnosed within 2–3 weeks and is attached to bone, your surgeon may recommend repair using internal-brace reinforcement. For mid‑substance tears, delayed injuries (over 3 weeks), or poor tissue quality, tendon‑graft reconstruction (hamstring or Achilles) is usually the best option. The decision is based on your tissue type, injury age, and tear pattern.
Other factors also affect the surgical plan for more severe injuries. If the tear involves nearby structures like the posterolateral corner, reconstruction is often the better choice. It provides more substantial support and helps prevent long-term instability. Your surgeon will also look at your activity level, knee alignment, and return-to-sport goals. At Total Orthopedics & Sports Medicine, we assess all these factors to recommend the most effective approach for restoring knee function and preventing future instability. Book your consultation today.
Which Imaging Tests Are Used to Plan LCL Surgery?
Doctors primarily use magnetic resonance imaging (MRI) to plan LCL surgery, as it clearly shows the exact location and extent of the tear. They may also order X-rays to check for fractures or joint alignment issues, especially after trauma. In some cases, stress X-rays or ultrasound help assess ligament looseness and guide treatment decisions.
For more severe cases, your surgeon may also use other tests to guide the procedure:
- MRI with contrast to detect subtle ligament damage or scar tissue from older injuries
- 3D CT scans to analyze bone structure and guide tunnel placement for multiligament reconstruction
- EMG testing to assess peroneal nerve function if symptoms like foot drop or numbness are present
- Diagnostic arthroscopy is used when imaging is unclear and direct joint visualization is needed
Can LCL Injuries Heal Without Surgery?
Yes, mild or partial LCL injuries can heal without surgery if treated early. Your doctor may recommend rest, bracing, gentle exercise, and anti-inflammatory medication to reduce pain and promote healing. In many cases, activity modification and early weight-bearing with a hinged knee brace can also support recovery while protecting the ligament.
Recovery depends on the injury grade and your progress with rehabilitation. Most people with low-grade LCL sprains return to regular activity within 6 to 8 weeks. However, factors like age, overall health, or physical demands can affect healing time. Some Grade 2 tears may not fully recover with conservative treatment and could later need surgical repair. To guide your recovery, your doctor might order follow-up imaging like dynamic ultrasound or adjust your rehabilitation plan if knee stability doesn’t improve.
At Total Orthopedics & Sports Medicine, we monitor your progress closely and adjust your treatment plan as needed to prevent long-term complications. Contact us at 855-321-6784 to begin your recovery.
What Are the Complications After LCL Reconstruction Surgery?
LCL reconstruction is generally safe, but complications can include stiffness, infection, nerve irritation, or graft failure. You might also experience lingering knee instability if rehabilitation is delayed or incomplete. Most issues are rare and manageable with early care and follow-up.
However, delaying surgery or having additional ligament injuries increases the risk of complications after LCL reconstruction. In these cases, excess scar tissue (arthrofibrosis) can form inside the joint, which may limit knee motion and occasionally require a follow-up procedure. You might also feel discomfort from surgical hardware, such as screws or bone tunnels placed during the operation. As recovery progresses, the graft may stretch, especially if the knee isn’t well-aligned or rehab is rushed. This can lead to renewed instability.
In rare cases, uneven joint pressure or poor blood flow may increase the risk of early arthritis. Following a structured rehabilitation plan helps prevent these issues and supports long-term knee function.
How Can Athletes Prevent Future Knee Ligament Injuries?
Athletes can prevent future knee ligament injuries by strengthening the muscles around their knees, improving balance, and using proper form during sports. A structured training plan focusing on flexibility, agility, and joint control can also lower the risk. Make sure to warm up before activity, wear proper gear, and avoid returning to play too early after an injury.
To protect your knees long term, focus on these key training strategies:
- Add neuromuscular drills to improve landing and reaction
- Cross-train with low-impact sports like swimming or cycling
- Practice safe jumping and quick turns with a coach or therapist
- Stay hydrated and eat foods that support joint health
- Use a brace after past injuries to reduce reinjury risk
- Follow a gradual return-to-play plan with medical guidance
Total Orthopedics & Sports Medicine Can Help You Decide If LCL Surgery is Right For You — Book a Visit Now!
If your knee feels unstable weeks after a sports injury, it could indicate a more serious ligament tear, such as an LCL injury. Unlike minor sprains, LCL tears often do not heal completely with rest and home care alone. Without timely medical intervention, the ligament may not regain its full strength, leading to ongoing joint instability. Over time, this can result in a limited range of motion, a higher risk of reinjury, and even early-onset arthritis.
At Total Orthopedics & Sports Medicine, we guide your care every step of the way. Whether you need bracing, rehabilitation, or LCL surgery, our team uses advanced imaging to assess the injury and plan effective treatment. We focus on restoring knee strength, stability, and function so you can recover properly. Contact us at 855-321-6784 to book your visit today.
FAQs
What Are the Risks of Skipping LCL Surgery?
Skipping LCL surgery can lead to joint instability, cartilage damage, and early arthritis. When the outside of the knee remains unsupported, nearby structures experience extra stress, increasing the risk of further injuries. In severe tears, the torn ligament ends often fail to heal without surgery, which may lead to prolonged recovery and more complex procedures later on.
How Long Is the Recovery After LCL Surgery?
Recovery after LCL surgery usually takes 6 to 12 months. The full recovery time depends on the severity of the injury and whether you had open surgery or a small incision procedure. If you have severe tears or other injuries, healing may take longer. Still, with proper care and a guided rehabilitation plan, most patients regain full function and return to activity safely.
How Common Is LCL Surgery Among Athletes?
LCL surgery is relatively common in athletes who suffer severe injuries to the outer side of the knee. These injuries often involve complete ligament tears or damage near the bone attachment points, such as the femur or fibula. When the joint remains unstable despite bracing, surgery is often necessary. It helps restore knee strength and protects against further injury.
Can I Walk Normally After an LCL Tear?
Yes, you can walk normally after an LCL tear, but it depends on the severity of the injury. Mild cases often heal with rest and exercise, allowing the knee to regain strength. However, when the tear is more serious, especially near the lower leg bone, the joint may feel unstable under pressure. Without treatment, this can cause a limp or weakness. In such cases, surgery helps restore movement and prevent other knee injuries.
When Is Revision LCL Surgery Necessary?
Revision LCL surgery is necessary when the initial repair fails to restore knee stability. This can happen if the torn ends don’t heal properly or if the joint remains loose after recovery. In some cases, new injuries to the outside of the knee or damage to the thigh bone can also cause surgical failure. These situations often require an open procedure with close follow-up to ensure successful healing.
Can Treatments Like PPR Help Avoid LCL Surgery?
Yes, PRP therapy can help avoid surgery in mild LCL injuries by reducing inflammation and supporting healing. It’s often effective for low-grade sprains or partial tears. However, in severe injuries like full tears or detachment from the lower leg bone, PRP cannot fully restore ligament stability. In these cases, surgery is necessary to repair the torn ends and protect the outside of the knee from further damage.
Will Insurance Cover LCL Surgery After a Sports Injury?
Yes, most insurance plans cover LCL surgery after a sports injury, especially when imaging confirms a full tear. Coverage often includes procedures involving general anesthesia, crutches, or an open procedure, but exact benefits depend on your plan. It’s important to check those details in advance. At Total Orthopedics & Sports Medicine, we provide treatment covered by your insurance, so you can focus on healing and recovery.
