Post-Surgery Knee Pain: Can I Run and What Exercises Are Safe? - Orthopedics

More Info

After undergoing knee surgery, particularly for ligament repair and reconstruction, it's common to have concerns about returning to physical activities like running. Given your history of surgery on your left knee, including the repair of the medial ligament and the replacement of the posterior cruciate ligament, it’s essential to approach your recovery and return to exercise with caution.


Can You Run?
Running can be a high-impact activity that places significant stress on the knee joint. After knee surgery, especially involving ligaments, it is generally recommended to wait until you have regained sufficient strength, stability, and range of motion in your knee before considering running. This process can take several months to years, depending on individual recovery rates and the extent of the initial injury.

Since you mentioned that your knee has improved significantly over the past three years, this is a positive sign. However, the re-emergence of pain and the "BBBB..." sound when bending your knee could indicate underlying issues such as cartilage wear, ligament laxity, or even the presence of scar tissue. It’s crucial to consult with your orthopedic surgeon or a physical therapist to assess your knee's current condition and determine if running is advisable.


Safe Exercises
In addition to swimming, which is an excellent low-impact exercise that helps build strength without stressing the knee, consider the following activities:
1. Cycling: Stationary or outdoor cycling can help improve your knee's range of motion and strengthen the muscles around the joint without the impact associated with running.


2. Elliptical Training: This provides a low-impact cardiovascular workout that mimics running without the stress on your knees.

3. Strength Training: Focus on strengthening the muscles around the knee, including the quadriceps, hamstrings, and calves. Exercises such as leg presses, hamstring curls, and calf raises can be beneficial. Always use proper form and avoid heavy weights initially.

4. Balance and Stability Exercises: Incorporate exercises that improve your balance and proprioception, such as single-leg stands or using a balance board. This can help enhance knee stability.

5. Flexibility and Stretching: Regular stretching of the muscles around the knee can help maintain flexibility and prevent stiffness.


Protective Measures
When engaging in any physical activity, consider the following protective measures:
- Knee Brace: A knee brace can provide additional support and stability, especially during activities that may put stress on the knee.


- Proper Footwear: Ensure you wear supportive shoes that provide good cushioning and stability.

- Gradual Progression: Start with low-impact exercises and gradually increase intensity and duration as your knee allows. Listen to your body and avoid pushing through pain.


Regarding the Artificial Ligament
Artificial ligaments, such as those used in your surgery, do not have a strict expiration date like a perishable item. However, their longevity can be influenced by factors such as activity level, body weight, and overall joint health. Regular follow-ups with your orthopedic surgeon are essential to monitor the condition of the ligament and the knee joint. If you experience significant pain, instability, or changes in function, these could be signs that further evaluation is necessary.


Conclusion
In summary, while returning to running after knee surgery is possible, it requires careful consideration and a structured rehabilitation approach. Focus on low-impact exercises, strengthen the surrounding muscles, and consult with your healthcare provider to ensure a safe return to running. Pay attention to any new symptoms, and don't hesitate to seek professional advice if you have concerns about your knee's condition.
