Avoid post operative bracing to reduce ACL rerupture rates

It has been quoted that the graft is more prone to injury in the early stages of ligamentization between 3 and 6 months when the muscles are weak and compliance with post-op protocol is waning. Purpose of this study was to evaluate the functional outcome of avoiding postoperative bracing following ACL reconstruction and early enhanced recovery protocol on the reinjuries of graft.

Thirty-two consecutive patients who underwent arthroscopic ACL reconstruction by a single surgeon in the same specialist center between October 2015 and May 2017 were included in the study. All the patients were educated regarding rehabilitation before the index surgery and preoperative quadriceps exercises had been initiated. Rehabilitation was undertaken as per a standard protocol with emphasis on early mobilization. No brace was used. Patients were followed up between 3 months and 1 year. Lysholm knee scores were evaluated at 6 and 12 months postoperatively.

No failures were noted (failure defined as instability, stiffness or persistent pain). The average Lysholm knee score at 6 months was 88 and at 12 months period was 91. No statistical significance (P > 0.00001) was noted in the scores between braced and unbraced at 1 year.

ACL rehabilitation without a knee brace can indirectly prevent rerupture and is a cheaper as well as a safer method with better outcomes.
