运动损伤者膝软骨修复自体骨软骨移植较微骨折术好
Study: OAT may offer better outcomes than MF for knee cartilage repair in athletic patients.
Findings from a study published in the November issue of the American Journal of Sports Medicine suggest that the osteochondral autologous transplantation (OAT) technique for repair of articular cartilage defect (ACD) or osteochondral defect (OCD) in the knee may allow athletes a higher rate of return to and maintenance of sports at preinjury levels compared with microfracture (MF). The research team conducted a randomized controlled trial of 60 athletes with symptomatic ACD or OCD in the knee. At 10-year follow-up, there were 4 failures (14 percent) in the OAT group and 11 failures (38 percent) in the MF group. In addition, the ICRS and Tegner scores of athletes younger than 25 years at the time of primary surgery remained significantly higher after 10 years compared with older patients, and 15 of 20 patients (75 percent) in the OAT group and 8 of 22 patients (37 percent) in the MF group maintained the same physical activity level.
