Surgeons test patient's own tendon as cheaper knee cartilage replacement
Researchers describe a new surgical technique using a patient's own hamstring tendon to replace damaged knee meniscus, potentially bypassing the cost and scarcity problems of donor tissue transplants. If validated, the approach could expand access to meniscus replacement surgery and reduce healthcare costs for orthopedic procedures affecting millions of people annually.
Originaltitel: Meniscal Substitution With a Semitendinosus Tendon Autograft
Abstract The menisci play a critical role in load transmission and shock absorption and serve as important secondary stabilizers of the knee. Unfortunately, meniscal repair is not always feasible, and resection may be required. Meniscal allograft transplantation is an established method of meniscal substitution; however, its use remains limited by graft sizing challenges, high costs, and restricted availability. The semitendinosus tendon has the capacity to remodel and revascularize within the intra‐articular environment. The purpose of this technical note is to describe the surgical technique for meniscal substitution using a semitendinosus tendon autograft.
