Abstract

Jogging is commonly performed in the latter stages of the rehabilitation program (2½-3 months) following ACL reconstruction. However, its cyclic loading effect on the ACL graft, 4-6 months after surgery has not been examined. Therefore, the purpose of this study was to examine changes in anterior knee laxity before and after 15 minutes of jogging on the treadmill. Subjects (N=l 1) were 8 males and 3 females (X age= 30.27 ± 4.76 years; heights= 175.7 ± 10.7 cm; weights= 81.1 ± 15.9 kg) with unilateral ACL reconstruction (central 1/3 patellar tendon graft, postoperation range = 4-6 months). Measurements were made using KT-2000 ( MEDmetric, San Diego, CA) and recorded in millimeters of displacement at 133 N (30 lb) of anterior force. Data were analyzed with a paired t-test at P < 0.05. Results showed no statistical difference between the ACL reconstructed knee and the normal knee after exercise. This study concluded that ACL reconstructed knee with the central 1/3 patellar tendon graft, 4-6 months after surgery, performs similarly to the normal knee when stressed with jogging for 15 minute at speed of 5-6 mph. Therefore, jogging is a safe and appropriate exercise for ACL-reconstructed patient at this stage after surgery.
