Post-operative tightness of the patella after posterior cruciate ligament surgery?
Hello Dr.
Lee, I had an accident while riding my bike in April this year, which resulted in a torn posterior cruciate ligament (PCL).
I underwent PCL reconstruction surgery in July, during which the surgeon asked me about the surgical materials I wanted to use, and I chose the button-type, as the surgeon explained it provides the best fixation.
For the ligament, they harvested a tendon from my thigh, and the surgeon recommended using an autograft since I am young.
Currently, my knee flexion is approximately 120-130 degrees (four months post-surgery).
What has been troubling me is that since about two months post-surgery, I frequently experience a tight sensation in the patellar tendon: 1.
This often occurs after maintaining a position for a long time; when I need to bend my knee, I feel tightness in the patellar tendon.
2.
I also feel a similar tightness and slight pain when climbing stairs.
3.
Prolonged standing also causes discomfort.
Currently, follow-up X-rays show no abnormalities.
I would like to ask the following questions: 1.
Is this tightness due to decreased muscle strength in my thigh from the surgery, or could it be related to post-operative adhesions? 2.
Are there methods to improve this, such as strengthening specific muscle groups or certain stretching exercises? 3.
Following up on question 2, is this just a post-operative sequela that is difficult to improve? 4.
I am a long-distance runner, typically running distances of 10-20 kilometers.
This tightness makes me very uncomfortable; does this mean I should refrain from running?

Hello, please be patient and continue rehabilitation for at least six months, with regular follow-up visits to discuss with your attending physician.
If muscle strength has not yet recovered, it is advisable to reduce the amount of exercise, but you can still run.
If you experience tightness after running, you can perform stretching exercises and apply local heat.
If you experience pain or discomfort, you should reduce your exercise volume (decrease distance, slow down your pace, or incorporate interval walking and running, etc.).

Post-ACL surgery, experiencing patellar tightness can be a common issue that many patients face during their recovery. Understanding the underlying causes and management strategies is crucial for improving your condition and returning to your desired activities, such as running.
1. Causes of Patellar Tightness: The tightness you are feeling in the patellar region can stem from several factors. One significant contributor is the decrease in quadriceps strength following surgery. The quadriceps muscle plays a vital role in knee stability and mobility, and any weakness can lead to compensatory mechanisms that may cause tightness or discomfort in the patellar tendon. Additionally, scar tissue formation or adhesions from the surgical procedure can restrict movement and contribute to the sensation of tightness. This is particularly relevant if you have been less active during the initial recovery phase.
2. Improvement Strategies: To address the tightness, a multifaceted approach is recommended:
- Strengthening Exercises: Focus on strengthening your quadriceps, hamstrings, and calf muscles. Exercises such as straight leg raises, squats (as tolerated), and leg presses can help rebuild strength. It's essential to perform these exercises with proper form to avoid further injury.
- Stretching: Incorporate stretching routines for the quadriceps, hamstrings, and calves. Gentle stretches can help alleviate tightness and improve flexibility. Consider using foam rollers or massage techniques to release tension in the surrounding muscles.
- Physical Therapy: Working with a physical therapist can provide personalized guidance and a structured rehabilitation program. They can assess your specific limitations and develop a plan that includes strengthening, stretching, and functional exercises tailored to your needs.
- Activity Modification: While you are recovering, it may be beneficial to modify your activities. If running exacerbates your symptoms, consider cross-training with low-impact exercises such as cycling or swimming, which can help maintain cardiovascular fitness without putting excessive strain on your knee.
3. Long-term Outlook: It’s important to recognize that some degree of tightness may persist as part of the healing process. However, with consistent rehabilitation efforts, many patients experience significant improvements over time. The key is to remain patient and committed to your recovery plan.
4. Running Considerations: As a long-distance runner, it's understandable that you want to return to your usual routine. However, listen to your body. If the tightness and discomfort persist, it may be wise to limit your running distance or intensity until you have adequately strengthened your knee and surrounding muscles. Gradually reintroducing running, starting with shorter distances and lower intensity, can help gauge your knee's response.
In summary, while patellar tightness post-ACL surgery can be frustrating, it is often manageable with the right strategies. Focus on strengthening and flexibility exercises, consider working with a physical therapist, and be mindful of your activity levels as you continue your recovery. With time and effort, many patients successfully return to their pre-injury activity levels, including running. Always consult with your physician or physical therapist before making significant changes to your rehabilitation or exercise routine.
