Regular physical activity improves general health but the frequency and intensity of physical activity required to produce benefits is not clear. To address this issue, Duncan and associates (Archives of Internal Medicine, 2005; 165: 2362-2369) conducted a randomized controlled clinical trial to evaluate the effects of different prescriptions of exercise intensity and frequency on cardiovascular disease risk factors.

Is There an Association Between Knee Height and the Prevalence of Knee Pain?
Mechanical forces exerted on the knee contribute to the development of knee osteoarthritis (OA). Among these, the additional torque about the knee associated with increasing leg length may predispose people of taller stature to knee OA. However, this association has received little prior investigation. In contrast to body height, which may decrease with age, knee height is relatively constant, making knee height a more appropriate surrogate for stature in the elderly.
Ethnic Disparities in the Consideration of TKR
Total knee replacement (TKR) is an effective, yet underutilized, treatment for severe knee osteoarthritis (OA). In particular, eligible minority patients tend to undergo TKR less often than white patients. The origins of these racial/ethnic disparities are incompletely understood, but may include both care-based (e.g. physician bias for recommending TKR) and patient-based (e.g. decisions not to undergo TKR if recommended) factors.
