Non-rachitic lesions of the knee are a common condition found in Nigerian children, the aetiology of which is unknown. 67 patients were studied, 24 had genu valgum, 28 genu varum and 15 with varo-valgum. Possible aetiology has been discussed and the following hypotheses have been put forward. The early weight bearing of the immature bones of the lower limbs has uneven pressure effects on the growth plate and also the laxity of the knee ligaments produces abnormal posture. The abnormal posture during growth and pressure effect of a tight band around the knee when the child is carried on the back predisposes to genu varum and valgum. Dietetic abnormalities may also be one of the factors but these have not been elucidated. Lastly, the tendency of the condition to occur in the African race raises the possibility of genetic factors.
