Summary
Combined proximal and distal realignment surgery effectively treats patellofemoral pain caused by malalignment. This surgical technique demonstrated high success rates, offering a reliable solution for patients experiencing this common musculoskeletal disorder.
Area of Science:
- Orthopaedic Surgery
- Musculoskeletal Disorders
Background:
- Patellofemoral pain is a prevalent musculoskeletal condition.
- Malalignment is a common cause of patellofemoral pain.
- Effective treatment strategies are crucial for improving patient outcomes.
Purpose of the Study:
- To evaluate the efficacy of a combined proximal and distal realignment technique for patellofemoral pain secondary to malalignment.
- To assess the long-term outcomes and complications of this surgical intervention.
Main Methods:
- Retrospective clinical study involving 108 knees in 98 patients.
- Treatment involved a combined proximal and distal realignment technique.
- Outcomes were evaluated using the modified Trillat grading scale and second-look arthroscopy.
Main Results:
- 81.4% of patients achieved good or excellent results at an average 29.2-month follow-up.
- Second-look arthroscopy showed good patellar tracking in most cases.
- Minor complications included anterior compartment syndrome and arthrofibrosis.
Conclusions:
- Combined proximal and distal extensor realignment surgery is a reliable and effective treatment for patellofemoral pain due to malalignment.
- The procedure yields favorable functional outcomes with a low complication rate.
- This surgical approach offers a viable option for managing recalcitrant patellofemoral pain.
