Knee gives us the freedom of mobility and the independence to live to the fullest. Yet it is the joint which wears out most commonly in our old age. It is a major weight-bearing joint, and a lot of demand is placed on it, in everyday life, as well as due to sports and athletics. The degeneration and the pain that it causes can be very troublesome. The disability that this condition of arthritis results in can be debilitating for some, even being a major cause of depression in old age.
And yet, many options exist for treatment of arthritis. If all medical management fails, or if arthritis is advanced, then exploring the correct surgical option is the way to go. Total Knee Replacement has undergone tremendous advancements in the last few years. These changes have happened in the design of the knee prostheses, as well as in the materials the knee implant is made up of. The newer designs focus more on patient comfort and longevity, ensuring that the patient does not ‘feel’ that a surgery has been done on the knee. This more ‘anatomical’ knee design works to provide a more ‘natural’ feel of the knee replacement procedure. The patient does not feel the ‘heaviness’ in the knee after the surgery like earlier designs. Also, the patient now exerts less while climbing stairs and getting up from sitting position. A lot of research has gone into knee kinematics and biomechanics; and the newer designs have passed on these benefits to the patients in the current clinical setting. The hi-flexion designs ensure that the implant allows the patient to bend the knee to allow sitting cross-legged. This is important in Asian lifestyle to carry out activities of daily living.
The knee is the largest joint in the body - and one that is vital to our active lifestyle. Be it our activities of daily routine or competitive sports, the stress and strain that goes through our knee joints is enormous, to say the least. And if there is a major injury to it - such as an ACL tear, it only causes the knee to degenerate at a much more accelerated rate. The ACL, as it is commonly known, is the Anterior Cruciate Ligament, and one of the primary and most important stabilizers of the knee joint. It provides AP (front-to-back) as well as rotational stability to the knee joint.
The treatment of an ACL Tear has progressed over the last few decades, and the recovery from this once crippling injury is now surprisingly fast and rewarding. The current treatment of an ACL tear focusses on
- Restoring normal stability of the knee joint
- Restoring the level of function before the ACL tear
- Preventing recurrent episodes of instability; and
- Preventing loss of function of the knee joint
