Comparative evaluation of knee stability following reconstruction of the anterior cruciate ligament with the bone-patellar tendon-bone and the double semitendinosus-gracilis methods: 1-and 2-year prospective study

An account of a prospective study of anterior cruciate ligament reconstructions with the bone-patellar tendon-bone autograft (BPTB) and the doubled semitendinosus-gracilis autograft (ST-GR) is given in 39 patients and 22 patients, respectively. The BPTB patients were younger, and there were more women in the ST-GR group. There were no statistical differences in the clinical and instrumental evaluations of stability after 1 and 2 years (Lachman and Jerk test, KT1000) between the two groups. Slightly better results were obtained in the BPTB group: mean 0.80 and 0.96 (first and second years) versus 1.18 and 1.20. Both methods, in fact, resulted in very satisfactory anterior knee stability, even when applied in two dissimilar groups of patients.
