Removal of meniscal tissue is described to result in poor knee function and a significant risk for future development of osteoarthritis. Different implants have been suggested to substitute a removed meniscus. Meniscal allograft transplantation is not widely available due to costs and availability. The semitendinosus tendon is a known graft with biological properties with potential to remodel and revascularize in an intraarticular environment such as anterior cruciate ligament reconstruction. The objective for this study was to investigate whether the semitendinosus tendon graft could function as a meniscal transplant.
