Knee Flexion Issues After Meniscus Repair Surgery - Orthopedics

More Info

---

After undergoing meniscus repair surgery and autologous cartilage transplantation, it's common to experience limitations in knee flexion during the rehabilitation process. Achieving a knee flexion of 90 degrees is a significant milestone, but if you find that you cannot bend your knee beyond this point, several factors could be contributing to this issue.

1. Healing Process: The meniscus and cartilage repair processes can take time. The meniscus, in particular, has a limited blood supply, which can slow down healing. If the meniscus is still in the process of healing, it may be stiff or swollen, which can restrict your range of motion. It's essential to follow your surgeon's guidelines regarding activity levels and rehabilitation exercises to ensure proper healing.

2. Scar Tissue Formation: After surgery, scar tissue can form around the knee joint, which may limit movement. This is a common occurrence after any surgical procedure, and it can lead to stiffness. Physical therapy is crucial in managing this, as targeted exercises can help break down scar tissue and improve flexibility.

3. Muscle Weakness: Post-surgery, the muscles around the knee, particularly the quadriceps and hamstrings, may weaken due to disuse. Weak muscles can lead to instability and difficulty in achieving full range of motion. Strengthening exercises are vital to regain muscle strength and support the knee joint.

4. Pain and Discomfort: Pain can also be a significant barrier to achieving full knee flexion. If you experience pain when attempting to bend your knee, it may cause you to subconsciously avoid pushing the joint to its limits. Managing pain through appropriate medications, ice therapy, and physical therapy can help you progress.

5. Physical Therapy: Engaging in a structured rehabilitation program is essential. Your physical therapist can provide specific exercises to improve knee flexion, strength, and overall function. They may also use modalities such as ultrasound or electrical stimulation to aid in recovery.

6. Consultation with Your Surgeon: If you continue to experience limitations in knee flexion, it’s crucial to communicate this with your orthopedic surgeon. They can assess your knee for any complications, such as joint effusion (swelling), or issues with the surgical site that may be affecting your recovery.

In summary, while it is possible that the meniscus is still healing and contributing to your limited knee flexion, other factors such as scar tissue, muscle weakness, and pain may also play significant roles. Continuing with physical therapy and following your surgeon's recommendations will be vital in your recovery process. If you have concerns about your progress, do not hesitate to reach out to your healthcare provider for further evaluation and guidance.
