Prognostic factors for partial meniscectomy
Studies into predictive factors influencing clinical outcomes post-arthroscopic partial menisectomy (APM) were explored. A number of variables were appraised for their influence, however only 3 showed moderate evidence. The presentation of radiographic OA, long-term duration of symptoms (>1 year) and resection of >50% of meniscus were associated with worse clinical outcomes.
Use of arthroscopy in the management of meniscal tears is common practice. However, recent evidence has suggested no further benefit in pain and function over physiotherapy in certain subgroups post APM, as well as an associated increased risk of OA. Identification of prognostic factors would allow the guidance of clinical reasoning and further refine best practice and optimal care.
The authors designed a systematic review to analyze best available evidence and identified key variables influencing clinical outcomes. The use of time from injury is commonly used in the consideration of surgical intervention, but classification of short vs. long term remains poorly defined in the literature. The authors concluded that longer term (3-12 months) from onset of injury was associated with poorer outcomes post APM.
Large resection of meniscus is widely known to be correlated with decreased satisfaction on patient reported outcomes. The study concluded >50% resection, leaving
