Summary
Closed lateral patellar retinacular release effectively reduced pain in patients with symptomatic patellofemoral osteoarthritis. This surgical treatment provided reasonable patient satisfaction, even with coexisting tibiofemoral arthritis.
Area of Science:
- Orthopedic Surgery
- Knee Osteoarthritis Research
Background:
- Patellofemoral osteoarthritis (OA) causes significant anterior knee pain.
- Surgical interventions aim to alleviate pain and improve function in OA patients.
Purpose of the Study:
- To evaluate the effectiveness of closed lateral patellar retinacular release for symptomatic patellofemoral OA.
- To assess patient-reported outcomes, including pain reduction and satisfaction.
Main Methods:
- Retrospective study of 50 patients (53 knees) undergoing lateral retinacular release.
- Assessment using Oxford knee score, visual analogue scale (VAS) for pain, and patient satisfaction questionnaires.
- Inclusion criteria allowed for patients with or without concurrent tibiofemoral arthritis.
Main Results:
- Mean follow-up was 31 months. Mean pain VAS decreased significantly, with 80% of patients reporting pain reduction.
- Average Oxford knee score was 27. Patient satisfaction varied, with 59% reporting satisfaction or very satisfied.
- Tibiofemoral disease presence did not impact outcome measures. Minor complications included superficial infections; no hemarthrosis occurred.
Conclusions:
- Arthroscopic lateral release is an effective treatment for reducing pain in symptomatic patellofemoral OA.
- The procedure offers reasonable patient satisfaction regardless of tibiofemoral arthritis presence.
