Accelerated rehabilitation after anterior cruciate ligamnet reconstruction (ACLR) involves early weight-bearing. During this phase the knee needs to be protected from excessive anterior tibial translation. This study assessed the amount of anterior tibial translation under two different body-weight shift exercises at 2-weeks post ACLR. The results were compared with that of healthy controls. Seven patients and seven controls were tested, the patients were 2 weeks post ACLR. Dynamic sagittal tibial translation was recorded during two exercises (1) weight shift side to side, (2) weight shift forward and backward. The results showed that there was no significant difference between the two exercises in the ACLR group. In the control group exercise 2 (side to side) resulted in more anterior translation than exercise 1 (forwards and backwards). The author concluded that at two weeks post ACLR both exercises can be used in rehabilitation.
