Post-ACL Surgery: Button Detachment and Recovery Challenges - Orthopedics

Post-operative button detachment of the posterior cruciate ligament?


Hello, doctor.
I had surgery at the end of June, and I started rehabilitation 18 days post-op.
I was able to walk slowly without crutches after 23 days.
Today, on August 14, during my follow-up appointment, an X-ray revealed that the button has completely detached from the bone, with one side elevated and the other side lowered.
Additionally, I have been experiencing pain near the button (which started around August 10).
When testing the calf for ligament laxity, the results were relatively normal.
Could this be caused by my excessive rehabilitation efforts? After my rehab sessions, I have been consistently doing flexion exercises, and I can almost reach 110 degrees after about six weeks.
Or could this be related to the fact that I haven't been wearing a brace?

Post-ACL surgery recovery can be a complex process, and it’s understandable to have concerns about complications such as button detachment and pain during rehabilitation. Based on your description, it seems you are experiencing button detachment, which can occur after ACL reconstruction, particularly when using devices like buttons or anchors to secure grafts.

Understanding Button Detachment
In ACL reconstruction, surgeons often use buttons or anchors to secure the graft in place. These devices are designed to hold the graft tightly against the bone, allowing for proper healing and integration. However, if the button becomes detached, it can lead to instability in the knee and may cause pain. The detachment could be due to several factors, including:
1. Improper Placement: If the button was not securely placed during surgery, it might not hold up under stress.

2. Excessive Stress: Engaging in rehabilitation exercises too aggressively or without proper support can place undue stress on the knee, potentially leading to detachment.

3. Inadequate Healing: If the bone or soft tissue has not healed sufficiently, the button may not have a stable base to hold onto.


Recovery Challenges
Your experience of pain around the button area, especially after increasing your rehabilitation intensity, raises some important considerations. It’s crucial to balance rehabilitation exercises with adequate rest and protection of the knee. Here are some points to consider:
1. Gradual Progression: While it’s great that you’re achieving a range of motion (ROM) close to 110 degrees, it’s essential to ensure that you’re not pushing too hard too soon. Gradual progression in physical therapy is key to avoiding complications.


2. Use of Brace: Not wearing a brace during your rehabilitation could contribute to instability, especially if you are performing exercises that put stress on the knee. A brace can provide additional support and prevent excessive movement that might lead to button detachment.

3. Pain Management: The pain you’re experiencing could be a sign that the knee is not ready for the level of activity you’re engaging in. It’s important to listen to your body and communicate with your physical therapist or surgeon about any pain that arises during rehabilitation.


Recommendations
1. Consult Your Surgeon: Given the button detachment and pain, it’s crucial to follow up with your surgeon. They may recommend imaging studies, such as an MRI, to assess the situation more thoroughly and determine if further intervention is needed.

2. Modify Rehabilitation: Work closely with your physical therapist to adjust your rehabilitation program. They can help you find a balance between strengthening the knee and allowing it to heal properly.
3. Rest and Ice: If you’re experiencing pain, consider resting the knee and applying ice to reduce inflammation. This can help alleviate pain and promote healing.

4. Strengthening Exercises: Focus on low-impact strengthening exercises that do not place excessive stress on the knee. Gradually increase intensity as tolerated.

5. Monitor Symptoms: Keep track of any changes in pain or function and report these to your healthcare provider. This information can be vital for adjusting your treatment plan.

In conclusion, while button detachment and pain can be concerning, they are not uncommon in the recovery process after ACL surgery. With proper management, communication with your healthcare team, and a balanced rehabilitation approach, you can work towards a successful recovery. Always prioritize your body’s signals and seek professional guidance when needed.
