Abstract
1. The menisco-femoral ligaments, extending from the posterior horn of the lateral meniscus to the lateral aspect of the medial femoral condyle, were found in ninety-nine (71 per cent) of the 140 knees examined. Fifty per cent of the ligaments were identified as the anterior menisco-femoral ligament while the remaining 50 per cent were of the posterior type. 2. During flexion of the knee with the foot fixed the menisco-femoral ligaments pull the posterior horn medially and slightly anteriorly, increasing the congruity between the meniscotibial socket and the lateral femoral condyle. 3. During lateral rotation of the femur with the knee flexed the menisco-femoral ligament pulls the posterior horn medially and slightly anteriorly, in this way increasing the risk of the posterior horn being crushed by the lateral femoral condyle. It is suggested that this is prevented by the contraction of the tibio-meniscal portion of the popliteus muscle which pulls the posterior horn of the lateral meniscus posteriorly. 4. When removing the lateral meniscus it may be advisable to make another incision in order to free the posterior horn from its attachment to the popliteus muscle and then to cut the menisco-femoral ligaments under direct vision.
