Abstract The management of patients with an apparently normal functional total knee arthroplasty TKA suffering from unexplained persistent pain and swelling is a challenging issue. The usual causes of pain after total knee replacement are well known but there are a small number of patients in whom its aetiology is obscure. Malfunction due to soft tissue impingement has rarely been reported. A patient with an unusual case of posterior soft tissue impingement secondary to a trapped posterior horn of a remnant medial meniscus after TKA and responsible for severe early polyethylene wear is reported. The diagnosis was confirmed by arthroscopy. Treatment was performed by arthrotomy. The meniscus remnant was removed followed by total synovectomy and isolated exchange of the polyethylene insert. To our knowledge this is the first well-documented case reporting this association. Case presentation A 63-year old male patient with a history of symptomatic osteoarthritis of the left knee
