The Knee

The knee is the largest joint in the human body.

The knee joint also withstands a lot of stress even in daily activities. For example, the pressure on the knees while climbing stairs or running is about 3 x body-weight.

This is one reason why the knee is prone to experiencing wear-and-tear problems.

Common Symptoms & Possible Cause of knee problems

Symptoms: Pain on prolonged walking or standing (Click here to learn more)
- Possible causes: cartilage or meniscus damage, leading to poorer shock absorption
Symptoms: Pain during or after running or exercises (Runner's knee)
- Possible causes: cartilage damage, including minor thinning of cartilage, tear or ulcer in cartilage
Symptoms: Pain at the front of the knee, when climbing stairs, or getting up after being seated for some time
- Possible causes: cartilage damage beneath the kneecap
Symptoms: Pain when bending knee, or pain when squats(Click here to learn more)
- Possible causes: cartilage damage beneath the kneecap, meniscus injury
Symptoms: Pain at the inner side of knee
- Possible causes: cartilage wear and tear on inner side of knee, medial ligament injury, meniscus injury
Symptoms: Pain at the back of knee
- Possible causes: meniscus tear, posterior ligament injury, muscle strain
Symptoms: Hearing a pop of the knee
- Possible causes: ligament tear, meniscus tear
Symptoms: Giving way or ‘weakness’ of the knee
- Possible causes: ligament tear, meniscus tear, cartilage damage
Symptoms: Feeling something move inside the knee
- Possible causes: loose body inside knee
Symptoms: Episodic sharp pain of the knee

Structure of the Knee

Common knee conditions in our practice:

Osteoarthritis -
- degenerative arthritis of the knee. Various treatment options include oral supplements, lubricant gel injection, marrow supplementation, key-hole procedure to repair knee, or knee replacement.
Acute Ligament tears -
- most common is Anterior Cruciate Ligament (ACL), followed by MCL and PCL. Complete ACL tears are routinely treated with surgery to reconstruct the ligament.
Chronic ligament and tendon injuries -
- sometimes, an acute injury can become chronic causing persistent pain. Treatment options include physiotherapy, injections, and surgical procedures.
Cartilage damage -
- cartilage damage may occur slowly over months or suddenly due to an injury. Cartilage damage should be treated to prevent deterioration to arthritis.
Meniscus tears -
- commonly occur in middle-aged persons after prolonged walking or a holiday. Similar to cartilage damage, this should be treated to prevent deterioration to arthritis.
Abnormal bow-leggedness or knock-knee -
- the knee can become deformed due to degenerative arthritis. Because these are progressive conditions, they should be treated before they progress and affect walking and mobility.
Loose bodies -
- these are usually bone spurs which break off within the knee. They cause episodic, sharp pains. They should be removed through a standard key-hole procedure.
