Only nine studies met our inclusion criteria and they were all case series. Arthroscopic debridement of the mucoid degeneration of the ACL was safe and effective in the patient. Finally, partial meniscectomy was commonly performed simultaneously with ACL debridement in all studies, which arguably could be the reason for the postoperative improvement.
