Summary
Symptomatic discoid lateral meniscus surgery showed excellent outcomes. Partial meniscectomy yielded better results than total meniscectomy for these knee conditions.
Area of Science:
- Orthopedic Surgery
- Knee Meniscus Research
Background:
- Discoid lateral meniscus is a congenital anomaly.
- Symptomatic cases often require surgical intervention.
Purpose of the Study:
- To evaluate surgical outcomes for symptomatic discoid lateral meniscus.
- To compare the efficacy of partial versus total meniscectomy.
Main Methods:
- Retrospective analysis of 46 patients (47 knees) operated between 1981-1989.
- Classification of discoid meniscus types (Watanabe).
- Surgical techniques included percutaneous or arthrometric partial or total meniscectomy.
Main Results:
- Follow-up on 30 knees using Ikeuchi's knee scale.
- 90% of cases achieved excellent or good outcomes.
- Partial meniscectomy demonstrated superior results compared to total meniscectomy.
Conclusions:
- Surgical treatment for symptomatic discoid lateral meniscus is effective.
- Partial meniscectomy is the preferred surgical approach for better patient outcomes.
