mprimise between stability and flexibility as it permits a 150 degree bend to bring the heel up to the hip and also permits the tibia to rotate slightly to either side (Gates, 1986). The two rounded condyles of the femur fit nicely into two depressions of the tibia, where the knee cartilages (the menisci) act as shoch absorbers (Gates). The lateral collateral ligament and the medial collateral ligament (MCL) provide stability when the leg is extended(Gates). However, when the knee is flexed, the cruciate ligaments must keep the bones in the proper relationship(Gates). The various ligaments of the knee joints cooperate in order to maintain the stability of the joint, and the stronger the stresses the joint is subjected to, the greater the degree to which the ligaments are engaged (Peterson & Renstrom, 1986). Combination injuries are likely to occur as a result of violent impact, and the more violent the impact, the more serious and complicated the injuries.
             The traumatic injuries to the knee usually involve the ligaments (Ham
