Anterior cruciate ligament reconstruction and medial meniscus tear?


Hello, Doctor: In February, I underwent surgery for a torn anterior cruciate ligament along with a medial meniscus tear.
The surgeon used my tendon for the ligament reconstruction, and since the meniscus was torn in an area without blood supply, the surgeon opted for partial meniscectomy, stating it wouldn't affect function.
However, now the doctor says I can start jogging lightly, but after moving around, I experience pain on the inner side of my knee and at the location of the lateral collateral ligament.
Is this normal? I'm worried about the possibility of re-injury or tearing.

Dr. Shi Guozheng reply Orthopedics


It is a normal phenomenon to gradually increase activity levels.
The ligaments will have healed after two months.
Unless there is a significant injury, they are unlikely to rupture again.

Understanding ACL Reconstruction and Meniscus Repair: What to Expect
Hello! It sounds like you have undergone a significant surgical procedure involving both ACL reconstruction and meniscus repair. These surgeries are quite common, especially among athletes or individuals who engage in high-impact sports. Let's break down what you can expect during your recovery and address your concerns regarding knee pain.


ACL Reconstruction Overview
The anterior cruciate ligament (ACL) is crucial for knee stability, and its injury often requires surgical intervention. In your case, the surgeon used your own hamstring tendons to reconstruct the ACL. This method is widely accepted and has shown good outcomes in terms of stability and function. The decision to use your own tissue (autograft) rather than a donor graft is often made to reduce the risk of rejection and improve integration with your body.


Meniscus Repair
Regarding your meniscus, it’s common for surgeons to perform a partial meniscectomy (removal of the damaged part) when the tear is in a region that lacks a good blood supply, as this area is less likely to heal on its own. While this may sound concerning, many patients can still maintain good knee function after such a procedure. The goal is to preserve as much of the meniscus as possible, as it plays a vital role in load distribution and shock absorption in the knee joint.


Post-Operative Expectations
After ACL reconstruction and meniscus repair, it’s normal to experience some pain and swelling as your body heals. The timeline for recovery can vary significantly from person to person, but here are some general expectations:
1. Initial Recovery: In the first few weeks post-surgery, you may experience pain, swelling, and limited range of motion. Physical therapy is crucial during this phase to regain strength and mobility.

2. Rehabilitation: Your rehabilitation program will likely include exercises to improve flexibility, strength, and stability. It’s essential to follow your physical therapist's guidance closely to avoid complications.

3. Return to Activity: Most patients can gradually return to light activities, such as walking or jogging, around 3 to 6 months post-surgery, depending on their progress. However, high-impact sports may require a longer recovery period.


Addressing Your Concerns
You mentioned experiencing pain on the inner side of your knee and near the lateral collateral ligament (LCL) after attempting to jog. Here are a few points to consider:
- Normal Post-Surgical Pain: It’s not uncommon to feel discomfort in various areas of the knee as you begin to increase your activity level. This can be due to the healing process, muscle imbalances, or even overexertion.

- Muscle Weakness: After surgery, the muscles around your knee, including the quadriceps and hamstrings, may weaken. This can lead to instability and discomfort during movement. Strengthening these muscles through targeted exercises is crucial for recovery.

- Knee Stability: If you are concerned about the possibility of re-injury, it’s essential to communicate this with your healthcare provider. They may recommend imaging studies, such as an MRI, to assess the integrity of the ACL and surrounding structures.

- Physical Therapy: Continuing with physical therapy is vital. Your therapist can help you modify your exercises to avoid pain while still promoting healing and strength.


Conclusion
In summary, while some discomfort is expected as you recover from ACL reconstruction and meniscus repair, it’s essential to monitor your symptoms closely. If the pain persists or worsens, or if you experience any instability in your knee, it’s crucial to consult your surgeon or physical therapist for further evaluation. They can provide tailored advice and adjustments to your rehabilitation program to ensure a safe and effective recovery. Remember, patience is key in the healing process, and following your rehabilitation plan will help you return to your desired activities safely.
