It is caused by a force being applied to the side of the knee when the foot is placed on the ground.ĭamage to the collateral ligaments can be assessed by asking the patient to medially rotate and laterally rotate the leg. Injury to the collateral ligaments is the most common pathology affecting the knee joint. It prevents posterior dislocation of the tibia onto the femur.Ĭlinical Relevance: Injury to the Knee Joint Collateral Ligaments
Proximally, it attaches to the medial epicondyle of the femur, distally it attaches to the medial condyle of the tibia. Tibial (medial) collateral ligament – wide and flat ligament, found on the medial side of the joint.They act to stabilise the hinge motion of the knee, preventing excessive medial or lateral movement Collateral ligaments – two strap-like ligaments.Patellar ligament – a continuation of the quadriceps femoris tendon distal to the patella.Now younger, more active people are increasingly being considered.The major ligaments in the knee joint are: In the past, a partial knee replacement was considered only in people 60 and over who were sedentary.The angulation of the deformity is also considered. You must have an intact anterior cruciate ligament, a sufficient range of knee motion, damage to only one compartment and a stable knee.However, your surgeon may not know for certain if you are a good candidate until the surgery has begun. An X-ray of the knee will determine your eligibility for partial knee replacement.
Once partial knee replacement was reserved for older patients who were involved in few activities. In a partial knee replacement, only the damaged part of the knee cartilage is replaced with a prosthesis. This surgery can be done when the damage is confined to a particular compartment of the knee. A partial knee replacement is an alternative to total knee replacement for some people with osteoarthritis of the knee.
