Does arthroscopic treatment of FAIS provide sustained clinically meaningful outcomes at 5-year follow-up?
Arthroscopic treatment for FAIS yields clinically meaningful improvements that peak at 2 years and are largely maintained at 5 years.
The greatest proportion of patients achieved MCID, PASS, and SCB at 2-year follow-up after arthroscopic treatment of FAIS compared with 1- and 5-year time points. Improvements were maintained out to 5-year follow-up, although the proportion of patients achieving clinical significance was slightly decreased.
Nwachukwu et al. (2020) studied this question.
