title: [Quadriceps and hamstring strength after anterior cruciate ligament rupture treated operatively with Leeds-Keio prosthesis and without surgery].
abstract: 69 patients with the ACL rupture: 40 non-operated, without functional knee instability, and 29 after the ACL reconstruction using Leeds-Keio prosthesis due to knee instability have been evaluated. Isometric dynamometric examination of the quadriceps and hamstring muscles was performed. The mean strength deficit in non-operated group was: quadriceps--18.48%, hamstring--7.19%, in operated group was: quadriceps--11.87%, hamstring--10.30%. The higher strength deficit of the quadriceps and lower of the hamstring in non-operated patients may be the sign of an adaptational mechanism to the ACL deficiency. No statistical correlation between the strength deficit and the deficit of the thigh circumference 10 cm above the patella was found.
