Translation Of The Tibia During Isometric Contraction Of The Quadriceps, Charles V. Connors

Theses and Dissertations

The purpose of this study was to determine in normal knees, and in knees with anterior cruciate ligament absence, what effect maximal voluntary isometric contraction of the quadriceps has on translation of the tibia on the femur. Ten subjects with bilaterally normal knees, and nine subjects with one normal knee and the contralateral knee having an arthroscopic finding of absent anterior cruciate ligament were tested. Tibial translation was measured with a dial indicator at 15, 45 and 60 degrees of knee flexion. There was a measurable anterior translation of the tibia in all knees. An analysis of variance with post …
