A prospective randomized clinical study of mosaic osteochondral autologous transplantation versus microfracture for the treatment of osteochondral defects in the knee joint in young athletes

Gudas R, Kalesinskas RJ, Kimtys V, et al. · Arthroscopy

At mean 37 months, 96% excellent/good results with OAT vs 52% with microfracture; 93% vs 52% returned to pre-injury sport (P < .001).

Population

57 athletes under 40 with femoral condyle osteochondral defects (28 OAT, 29 microfracture)

Intervention

Mosaic-type osteochondral autologous transplantation (OAT)

Comparator

Microfracture

Limitations

Single-center; young athletic population limits generalizability; unblinded.
