Excellent health is probably the biggest and best predictor of results after total knee replacement (TKR). Numerous studies show a direct link between health before an operation and results after the surgery.

Patients who rate their health as “poor” are four to five times more likely to die. This is true despite differences in background, disease severity, and other psychologic or social issues.

A recent study at the University of Kansas in Wichita confirmed these findings for TKR patients. Those who rated their health as “good” to “excellent” had the best outcomes. Their health status improved dramatically from before to after the operation. Joint stiffness, pain, and function were used to measure health status.

The authors of the study pointed out that all their patients came from one orthopedic practice. Their results may not be the same for other groups.

Aging is linked with osteoarthritis (OA) of the joints. The hip and knee are affected most often.

Stiffness is also common as we get older. There are many reasons for this. Tendons and ligaments have less water in them. The drying effect makes the joints seem stiff. The cells that make up soft tissues are called collagen. Fewer new collagen cells are formed so we lose some elasticity in the joints and muscles.

There are other changes going on in the joints. The cartilage loses strength. Changes in the cells of the cartilage lead to OA. There is a thinning of the joint space as the cartilage breaks down. This loss in joint space can be seen on X-ray. It’s the most common way to diagnose OA.

A medical doctor will use tests of motion and strength along with X-rays to make the diagnosis. An early diagnosis is best so that early treatment can limit problems.
