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.

Description of novel surgical technique using autologous semitendinosus graft as meniscus transplant.
KISÖS
Stockholm, Sweden
RECRUITINGFailure
Surgical failure of transplant defined as meniscus symptoms (joint line tenderness, swelling, locking or positive McMurray) resulting in a need for re-arthroscopy and subtotal or total resection of the transplant.
