Aim. Reconstruction of the anterior cruciate ligament using autologous patellar tendon or semitendons involves two different types of functional adaptation in muscular and proprioceptive terms. The purpose of the present study was to monitor deficits at the end of the recovery process (150 day follow-up) between healthy and injured extremities, in two different groups.
Methods. Two groups were considered in this study, each consisting of 15 male subjects engaged in sporting activities. Both groups had undergone reconstruction of the anterior cruciate ligament, the first with autologous patellar tendon (PTG) and the second with semitendons (STG).
Results. Follow-up results in the two groups showed a significant difference between healthy and injured extremities in the parameter relative to maximum negative acceleration (44.99±6.41%, P<0.001) in the STG and a significant difference relative to the maximum ground impact force parameter (11.45±3.17%, P<0.001) in the PTG.
Conclusion. The two groups showed a different functional adaptation pattern at the end of the post-surgical rehabilitation period, which suggests that, in this regard, the two reconstruction techniques require special attention in the preparation of post-surgical rehabilitation programmes.
