Purpose: Previous studies have reported that Anterior Cruciate Ligament (ACL) reconstruction does not restore normal tibial rotation in patients with chronic instability and repeated episodes of giving way. We hypothesised that early ACL reconstruction, using quadruple hamstring autografts, before the pivoting episodes had occurred, would protect the knee joint from developing abnormal kinematics with increased external tibial rotation during flexion.
Methods: Fourteen consecutive patients (8 men, 6 women) with a median age of 24 years (18-43), with a complete, isolated unilateral ACL rupture and an intact contralateral knee, were studied.

If permission of full active and passive extension immediately after an anterior cruciate ligament (ACL) reconstruction will increase the post-operative laxity of the knee has been a subject of discussion. We investigated whether a post-operative rehabilitation protocol including active and passive extension without any restrictions in extension immediately after an ACL reconstruction would increase the post-operative anterior-posterior knee laxity (A-P laxity). Our hypothesis was that full active and passive extension immediately after an ACL reconstruction would have no effect on the A-P laxity and clinical results up to 2 years after the operation.

The KT-1000 and similar non-invasive arthrometers are used as a complement to clinical examination in the diagnosis of anterior cruciate ligament (ACL) rupture and during the follow-up after surgery. We compared the two methods, KT-1000 and Radiostereometric analysis (RSA), when used to measure anterior-posterior knee laxity (A-P laxity) in patients with ACL rupture, before and after the reconstruction of this ligament, in a prospective, comparative study. Twenty-two consecutive patients (14 men, 8 women) with a median age of 24 years (range 16-41) were studied.
