Post-ACL Reconstruction: Knee Pain While Climbing Stairs at 15 Weeks - Orthopedics

More Info

---

Post-ACL reconstruction recovery can be a complex process, and experiencing knee pain while climbing stairs at 15 weeks post-surgery is not uncommon. It’s important to understand that the recovery timeline can vary significantly from person to person, and several factors can contribute to the symptoms you are experiencing.

Firstly, the fact that you have achieved over 120 degrees of knee flexion is a positive sign, indicating that your range of motion is progressing well. However, the inability to fully squat and the pain when climbing stairs suggest that there may still be underlying issues that need to be addressed. Pain during stair climbing can be attributed to several factors, including muscle weakness, improper biomechanics, or even residual swelling in the joint.

Your rehabilitation physician's diagnosis of muscle weakness is particularly relevant. After ACL reconstruction, the quadriceps muscle often experiences atrophy due to disuse and the surgical procedure itself. Strengthening this muscle is crucial, as it plays a significant role in stabilizing the knee joint during activities such as climbing stairs. It is essential to engage in a structured rehabilitation program that focuses on gradually increasing the strength of your quadriceps and other supporting muscles around the knee.

The "clicking" or "popping" sounds you hear when extending or bending your knee, accompanied by mild pain, can be concerning. However, these sounds are not uncommon after knee surgery and can result from various factors, including the movement of tendons over bony structures or the presence of scar tissue. While these sounds can be benign, if they are associated with significant pain or instability, it would be prudent to consult your orthopedic surgeon or physical therapist for a thorough evaluation.

In terms of managing your symptoms, consider the following recommendations:
1. Continue Rehabilitation: Adhere to your rehabilitation program, focusing on strengthening exercises for your quadriceps, hamstrings, and calf muscles. Exercises such as straight leg raises, wall sits, and step-ups can be beneficial. Ensure that you are performing these exercises with proper form to avoid exacerbating your pain.

2. Ice and Elevation: If you experience swelling or pain, applying ice to the knee and elevating your leg can help reduce inflammation. This is particularly important after physical therapy sessions or any activity that aggravates your symptoms.

3. Gradual Progression: When attempting new exercises or activities, such as stair climbing or squatting, start slowly and gradually increase the intensity. If you experience pain, it’s essential to listen to your body and modify your activities accordingly.

4. Consultation: If your symptoms persist or worsen, it may be necessary to undergo imaging studies, such as an MRI, to rule out any complications such as meniscal tears, ligamentous injuries, or other structural issues. Your surgeon can provide guidance based on your specific situation.

5. Pain Management: Over-the-counter pain relievers, such as NSAIDs, can help manage pain and inflammation. However, consult with your healthcare provider before starting any medication.

6. Biomechanical Assessment: If pain persists, consider a biomechanical assessment by a physical therapist. They can evaluate your movement patterns and provide insights into any compensatory mechanisms that may be contributing to your pain.

In conclusion, while experiencing knee pain during stair climbing at 15 weeks post-ACL reconstruction can be concerning, it is not uncommon. Focus on strengthening your muscles, managing your symptoms, and maintaining open communication with your healthcare team. With time and appropriate rehabilitation, many patients can return to their pre-injury activity levels. Always prioritize your recovery and seek professional advice when in doubt.
