Kneeling and Knee Replacement

Interesting article which looked at the movement of the knee in knee replacement patient during a kneeling exercise. Technique uses X-ray images mapped with CAD images of implants to recreate the motion of the femoral component relative to the tibial component.

Article concludes that "Knee kinematics [during kneeling] was similar to other deep-flexion weight-bearing activities"

Article summarizes a clinical study that looks at the cause-effect relationship of arthritis and obesity. Study suggests that folks maintain or even gain weight following joint replacement. It had been assumed that folks would tend to lose weight after surgery because they would be able to be more active. Instead folks maintain or even gain weight slightly. This is disappointing since, excess weight will put additional stress on implants which could possibly limit the lifespan of the device. To see the full article visit:
