Surgical Treatment Options for Patellar Malalignment - Orthopedics

More Info

---

Patellar malalignment, particularly in the context of conditions like patellar chondromalacia or patellar instability, can significantly affect a patient's quality of life. Surgical treatment options are typically considered when conservative measures, such as physical therapy and bracing, have failed to provide relief. Understanding the surgical options available, their implications, and potential outcomes is crucial for making informed decisions.


Surgical Treatment Options
1. Lateral Release: This is a common procedure for patients with lateral patellar tracking issues. The surgery involves cutting the lateral retinaculum, which is the tissue that holds the patella in place. By releasing this tissue, the patella can move more freely and may align better during knee motion. However, this procedure is often combined with other techniques to ensure long-term stability.

2. Medial Patellofemoral Ligament (MPFL) Reconstruction: This procedure is often indicated for patients with recurrent patellar dislocations. The MPFL is a key stabilizer of the patella, and reconstructing this ligament can help in maintaining proper patellar alignment. This surgery involves using a graft (which can be taken from the patient or a donor) to replace the damaged ligament.

3. Osteotomy: In cases of significant malalignment due to bony deformities, an osteotomy may be performed. This involves cutting and realigning the bones around the knee joint to improve patellar tracking. For example, a tibial tuberosity osteotomy can be done to reposition the patellar tendon attachment, which can help in centering the patella over the femoral groove.

4. Patellar Realignment: This procedure involves repositioning the patella itself. Surgeons may use various techniques to adjust the position of the patella to ensure it tracks properly within the femoral groove during knee movement.

5. Arthroscopy: In some cases, arthroscopic surgery may be performed to clean out any loose bodies, repair damaged cartilage, or address other intra-articular issues contributing to patellar malalignment.


Potential Risks and Complications
As with any surgical procedure, there are risks involved. Some potential complications include:
- Infection: As with any surgery, there is a risk of infection at the surgical site.

- Blood Clots: Patients may be at risk for deep vein thrombosis (DVT) following surgery, especially if mobility is limited post-operatively.

- Persistent Pain: Some patients may continue to experience pain even after surgery, which can be due to various factors including the extent of the original condition or complications during surgery.

- Stiffness: Post-operative stiffness can occur, necessitating physical therapy to regain full range of motion.

- Recurrent Instability: In some cases, the surgery may not fully correct the malalignment, leading to continued instability or dislocation of the patella.


Post-Operative Care
Post-surgery, rehabilitation is crucial. Patients typically undergo a structured physical therapy program to strengthen the muscles around the knee, improve flexibility, and restore function. The timeline for recovery can vary based on the specific procedure performed, but many patients can expect to return to normal activities within several months.


Conclusion
In summary, surgical treatment for patellar malalignment involves various techniques tailored to the specific underlying issues. It is essential to have a thorough discussion with an orthopedic surgeon specializing in knee conditions to determine the most appropriate surgical option based on individual circumstances. Understanding the potential risks and benefits, as well as the expected recovery process, will help in making an informed decision regarding surgical intervention.
