this condition There is no other medical condition that is associated with more chronic disability in the elderly than knee osteoarthritis (Sharma, et al, 2003). Research, such as cross-sectional studies,
shows that leg strength, that is, quadriceps strengthening, can have a tremendous beneficial effect on osteoarthritis in the knees. Research shows that strengthening these legs muscles both reduces pain and
improves leg function (Sharma, et al, 2003). While the precise impact of quadriceps strengthening over the evolution of osteoarthritis remains poorly understood, studies have also demonstrated, in regards to individuals
with health knee joints, that having strong quadriceps offers a degree of protection to the individual against new osteoarthritis development (Sharma, et al, 2003). However, thus far, research has failed
to find an association between quadriceps strength and the progression of osteoarthritis in knees which are already arthritic (Sharma, et al, 2003). Investigation into this relationship is significant due to
the fact that quadriceps strengthening exercises are often prescribed for individuals with knee osteoarthritis. Why the researchers chose to do this study The effect of muscle strengthening exercise on
arthritic knees is far less predictable than its effect on healthy knees. Generally, strengthening "promotes cartilage health and stabilizes the joint" (Sharma, et al, 2003, p. 613). Muscles
tend to compensate and shield knee tissues from the wear and tear that comes from starting and stopping motion, as well as from the effects of gravity. It is generally
assumed that exercise enhances these positive protective effects, which is why strengthening exercise are recommended for osteoarthritic patients. However, if this assumption is not true, the interaction of muscles
against the diseased joint may impair, rather than improve, the regulation of motion and therefore reduce the "ligament-protection" features of musical action (Sharma, et al, 2003, p. 613). Whether
