Clinical Trial Summary

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.

Outcome

Type Measure Description Time frame Safety issue
Primary Failure 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. 2 years
Secondary Improved subjective knee function Patient reported outcome measure using the Knee Injury and Osteoarthritis Outcome Score (KOOS), 0-100 where 100 indicate best possible result. 2 years
Secondary Improved subjective knee function Patient reported outcome measure using Lysholm (0-100 where 100 indicate best possible result) and Tegner activity score (0-10, where 10 indicate the highest activity level) . 2 years
Secondary Improved subjective knee function Patient reported outcome measure using Euroqol 5 dimensions (EQ-5D) score (quality of life instrument with five dimensions with points from 1 to 3 where 1 indicates no problem and 3 indicate severe problems). 2 years
Secondary Improved subjective knee function Patient reported outcome measure using Global score (0-10 where 10 indicate best possible result) 2 years
