Dealing with Knee Problems

Medical Director
The Orthopaedic Centre


Dr David Su, Medical Director at The Orthopaedic Centre, shares the common causes of chronic knee pain and other knee problems like knee osteoarthritis and Anterior cruciate ligament (ACL) tears.

Chronic knee pain for people below 45 is commonly caused by overdoing and overuse from sports. As for those above 45, the common cause is age-related wear and tear leading to degenerative knee conditions. Three common knee pain problems are Patellofemoral Pain Syndrome (runner’s knee), knee osteoarthritis and knee ligament and cartilage injuries.

Runner’s knee happens when the kneecap is misaligned and rubs against the lower end of the femur. This is often caused by repetitive stress on the knees due to an excessive running or cycling routine. Dr David Su recommended that runners incorporate cross-training in their fitness routine to get a good mix of load on joints and muscles. Some supplements can help to stimulate the formation and repair of the cartilage or keep it from deteriorating.

The Knee
The knee joint, the largest and complex joint of the human body, takes an enormous amount of pressure for even simple day-to-day activities. For example, when climbing stairs or running, each knee joint may absorb three times the body weight. This is one reason why the knee joint is prone to experiencing wear-and-tear, called osteoarthritis. This refers to progressive damage of the cartilage, excruciating pain, restricted movement and reduced quality-of-life.

Knee Injuries
Injuries are the other quite common issues that are associated with knee problems. Some of the problems which are associated include conditions such as anterior cruciate ligament (ACL) tears, medial collateral ligament (MCL) tears, meniscus tears, cartilage injuries and patella dislocations. A lot of people, e.g. skilled sportspersons, sustain ACL tears due to activities such as football, basketball and skiing. An ACL tear, in a young patient, is best treated with surgery to reconstruct a new ACL, therefore giving the patient a good knee for the years to come.
