This article documents the recovery of muscle strength and functional performance in middle-aged patients before and after partial meniscectomy. Over a 2–year period, 23 patients who underwent an arthroscopic partial meniscectomy were tested 2 weeks before surgery and then 3 months and 12 months after surgery. Isometric muscle strength data was acquired from the knee flexors, knee extensors, and hip abductors. The time taken to generate the maximum force was used to calculate rate of force development. In addition, 2 functional tests were also measured: single leg squat for 30 seconds and maximum forward hop for distance.
