Management for degenerative meniscal tears
Current evidence does not support a role for arthroscopic partial meniscectomy, knee ‘washouts’, and arthroscopic debridement in the management of degenerative meniscal tears.
Many trials have not been able to show any clear benefit of surgery over placebo or nonsurgical treatment for degenerative meniscal tears. A 2019 Cochrane review1 identified a single study that compared arthroscopic partial meniscectomy to a 6-week individualised home physical therapy programPalmer, 2019. There was little difference in pain and function (at 12-months follow up) between people who had arthroscopic partial meniscectomy and those who had physical therapy.
A 2020 systematic review and meta-analysis2 evaluated the efficacy of arthroscopic partial meniscectomy for symptomatic degenerative meniscal tears associated with mild or no OALee, 2020. Five randomised controlled trials were included in the final analysis. There was relatively strong evidence that arthroscopic partial meniscectomy did not improve functional activity or reduce pain, compared with those who had nonsurgical treatment or sham operation.
