Revision anterior cruciate ligament reconstruction using tibial or hamstring tendon allografts.

Purpose: To report outcomes of revision anterior cruciate ligament (ACL) reconstruction using tibial or hamstring tendon allografts and to compare with another study using non-irradiated fresh-frozen bone-patellar tendon-bone allografts.

Methods: Records of 12 men and 7 women aged 18 to 53 (mean, 33) years who underwent revision ACL reconstructions using tibial tendon (n=17) or hamstring tendon (n=2) allografts were retrospectively reviewed. At the time of primary ACL reconstruction, hamstring autografts (n=8) and bonepatellar tendon-bone allografts (n=11) were used.

Medium-term outcome of mosaicplasty for grade III-IV cartilage defects of the knee.

Purpose: To evaluate the medium-term outcome of mosaicplasty for full-thickness cartilage defects of the knee joint in 17 patients.

Methods: Records of 12 men and 5 women aged 16 to 57 (mean, 35) years who underwent mosaicplasty for grade III/IV osteochondral defects in the lateral (n=14) or medial (n=3) femoral condyle were reviewed. 12 of the patients had undergone knee surgeries.

Synthetic resorbable scaffolds for the treatment of isolated patellofemoral cartilage defects in young patients: magnetic resonance imaging and clinical evaluation.

Background: Surgical management of patellar cartilage defects remains controversial. The ideal technique to regenerate hyaline cartilage is not yet defined. However, a synthetic resorbable osteochondral scaffold plug (TruFit CB) seems to offer a treatment option with good results at short-term follow-up, at least in the condylar setting.
