Fabella impingement syndrome after total knee arthroplasty (TKA) is a rare condition. However, the location of the inserted prosthesis and the size of the fabella are considered major causative factors. Thus far, a conventional surgical excision of the impinged fabella is recommended treatment for the impingement. A 72-year-old woman was diagnosed with degenerative arthritis of the knee. She complained of fabella impingement due to an incompletely excised bony spur behind the posterolateral femoral prosthesis after TKA. The fabella and remaining bony spur were removed using an arthroscopic procedure. The impingement has not recurred and the range of motion (ROM) of the knee was improved after a 12 months follow-up. Arthroscopic surgery might be an alternative treatment for fabella impingement after TKA.
