Alterations in knee joint kinematics have been suggested as a
potential mechanism that influences the development of osteoarthritis of the knee
after anterior cruciate ligament reconstruction. Whilst previous work has shown
changes in internal-external tibial rotation during level walking, many patients
aim to return to high impact activities following surgery. This study examined
tibial rotation during single limb hop and drop landings in anterior cruciate
ligament reconstructed knees compared to a control group, and also evaluated the
influence of graft type (hamstring or patellar tendon). METHODS: In 48
participants (17 patellar tendon graft, 18 hamstring graft and 13 controls)
internal-external rotation was measured during single limb hop and drop landings
in a gait laboratory at mean of 10months after surgery. FINDINGS: There was no
difference between the two graft types and both patient groups had less internal
rotation when compared to the control group. For 60% of patients, internal
rotation values were at least 5 degrees less than the control group mean.
INTERPRETATION: Anterior cruciate ligament reconstructed knees with both
hamstring tendon and patellar tendon grafts show altered rotational kinematic
patterns during high impact dynamic load activities.
