Arthroscopic Lysis of Adhesions for Treatment of Post-Traumatic Knee Arthrofibrosis: A Prospective Study.

Abstract

Post-traumatic knee arthrofibrosis can have a significant effect on patients' function and the management can bechallenging with a variety of options rangingfrom manipulation under anaesthesia (MUA) to more invasive procedures such as quadricepsplasty. The aim of the study is to evaluate the improvement of both knee range of motion (ROM) and functional outcomes after arthroscopic lysis of adhesions (ALA) forpost-traumatic knee arthrofibrosis. A prospective study of 30 patients with post-traumatic knee arthrofibrosis was managed by arthroscopic arthrolysis.Aggressive rehabilitation protocol was initiated on the first day postoperatively. Comprehensive clinical follow-up evaluations including the ROM assessment and the Lysholm score were done for all patients. The mean age was 36.17 years (±9.51). The mean follow-up time was 6.7 months (six to nine months). The ROM improved from 75° (±10.91°) preoperatively to 119.83° (± 10.38°) at the final follow-up (P < 0.001). Additionally, the Lysholm score increased from 56.90(±2.64) preoperatively to 85.27(±3.46) (P < 0.001). The ultimate final ROM and functional outcomes for all patients were satisfactory. ALA for knee arthrofibrosis significantly improves the knee ROM and functional outcomes and can be a successful alternative to open quadricepsplasty.
