Abstract
Functional reconstruction following a wide resection for a malignant musculoskeletal tumor is often challenging, particularly for juxta‑articular tumors. The current study describes a novel surgical procedure for the functional reconstruction of the knee extensor mechanism with a pedicle frozen auto‑bone and ‑tendon graft, in a case of prepatellar clear cell sarcoma. The active range of motion of the knee was from 0‑135˚, and the extension muscular strength of the knee was evaluated as 5/5 by a manual muscle test at 14 months post‑surgery (International Society of Limb Salvage score, 73%); this was improved compared with a similar procedure previously described by Muramatsu et al. This procedure must be considered following the wide resection of juxta‑articular malignant musculoskeletal tumors.
