Background Many factors affect recovery from arthroscopic partial meniscectomy, including patient sex. However, sex differences in time to maximal recovery of knee function and factors influencing differential rates of recovery are unknown. Questions/purposes We determined (1) preoperative sex differences, (2) sex differences in rate and extent of recovery through 1 year postoperatively, and (3) clinical and fitness variables that could explain potential sex differences in recovery from partial meniscectomy.
Patients and MethodsThe study sample consisted of 180 patients undergoing arthroscopic partial meniscectomy. Sex, age, body mass index, history of prior injury, length of time between knee injury/impairment and surgical evaluation, weekly exercise frequency, and self-reported fitness were assessed preoperatively, and extent of osteoarthritis was recorded postoperatively. We used the Tegner-Lysholm scale to assess knee function preoperatively and postoperatively at Weeks 1, 3, 8, 16, 24, and 48 followups.
