Background: Physiotherapy is indicated for treatment of a painful degenerative knee meniscus tear. Predicting the outcome remains uncertain. Objective: The purpose of this systematic review was to identify which predictive factors are associated with the outcome of physiotherapy for degenerative knee meniscus tear. Methods: A systematic electronic literature search was undertaken of PubMed, CINAHL, Medline with AMED and EMBASE via Ovid from inception to July 2021. Studies of adults receiving physiotherapy which presented data on the association of baseline variables and the treatment outcome were included. Study quality was assessed using CASP (Critical Appraisal Skills Programme) tools. Data were narratively analysed. Results: 1051 titles were retrieved and screened for eligibility. fifteen studies met the inclusion criteria. Nine studies investigated degenerative tears. The evidence-base was of low/moderate quality. Seven studies and five studies (100%) reported no association between mechanical symptoms and gender respectively (p>0.05). There was no association with osteoarthritis in 80% of studies, age in 71% of studies, or body mass index in 60% of studies (p>0.05). Three studies (75%) reported that higher baseline pain was associated with cross-over to surgery, worse pain or greater improvement with surgery (p>0.05). Conclusion: Patient demographic characteristics provide minimal association with outcome following physiotherapy for degenerative meniscus tear. The evidence-base is limited in size and quality. A large adequately powered prospective cohort study investigating a broad range of predictive factors is warranted to develop a predictive model to better stratify those most likely to benefit from physiotherapy.
