Patellar dislocation
Hello, Doctor.
I have a long-standing issue with habitual dislocation of my knee, and recently the frequency of dislocations has increased.
At night, I also experience inflammation and pain in my knee.
I consulted an orthopedic surgeon who recommended surgery to tighten one side of the ligaments while relaxing the other.
I would like to know if this surgery will temporarily prevent me from walking.
If so, how long will it take before I can walk again? How long is the rehabilitation process? The previous doctor mentioned that he has not performed this type of surgery, so he could not provide me with a clear answer.
Thank you.

More Info
Patellar dislocation, or kneecap dislocation, is a condition where the patella (kneecap) slips out of its normal position, often resulting in pain, swelling, and instability in the knee. Surgical intervention is typically recommended for individuals with recurrent dislocations, especially when conservative treatments such as physical therapy and bracing have failed. The surgery usually aims to stabilize the patella by tightening certain ligaments and possibly loosening others to restore proper alignment and function.
Understanding the Surgery
The specific surgical procedure for patellar dislocation can vary based on the underlying cause of the instability. Common techniques include:
1. Medial Patellofemoral Ligament (MPFL) Reconstruction: This is a common procedure where the ligament that helps keep the patella in place is reconstructed. A graft is taken from another part of the body or a donor to replace the damaged ligament.
2. Lateral Release: This procedure involves cutting the tight lateral structures of the knee to allow for better alignment of the patella.
3. Realignment Procedures: In some cases, the position of the patella or the bones of the knee may need to be adjusted to prevent future dislocations.
Recovery and Rehabilitation
Post-surgery, patients typically experience a recovery period that can vary significantly based on the individual’s health, the complexity of the surgery, and adherence to rehabilitation protocols. Here’s what you can generally expect:
1. Initial Recovery: After surgery, you may be required to use crutches for a period of time, which can range from a few days to several weeks, depending on the extent of the procedure and your surgeon's recommendations. During this time, you will likely be advised to avoid putting weight on the affected leg to allow for healing.
2. Walking Again: Most patients can begin to walk with assistance (using crutches or a walker) within a few days post-surgery. However, full weight-bearing activities may not be permitted for several weeks. Generally, you can expect to start walking independently within 4 to 6 weeks, but this timeline can vary.
3. Physical Therapy: Rehabilitation is a crucial part of recovery. Physical therapy usually begins shortly after surgery, focusing on gentle range-of-motion exercises to prevent stiffness. As healing progresses, the therapy will become more intensive, incorporating strengthening exercises to support the knee and improve stability. The rehabilitation process can last anywhere from 3 to 6 months, depending on the individual’s progress and the specific surgical procedure performed.
4. Return to Activities: Returning to sports or high-impact activities may take longer, often requiring 6 months to a year of rehabilitation. The timeline for returning to full activity will depend on the success of the rehabilitation program and the surgeon's assessment of knee stability.
Conclusion
In summary, while surgery for patellar dislocation can lead to significant improvements in knee stability and function, the recovery process requires patience and commitment to rehabilitation. It is essential to follow your surgeon's and physical therapist's advice closely to ensure the best possible outcome. If you have further questions or concerns about your specific situation, it’s advisable to consult with your orthopedic surgeon, who can provide tailored guidance based on your condition and surgical plan.
