People who have had knee replacement surgery typically have worse physical function compared to healthy people of similar age. This problem occurs despite completion of standard rehabilitation programs. One reason for less-than-optimal restoration of physical function is that standard rehabilitation does not effectively address habitual movement patterns that persist after surgery. These movement patterns are characterized by patients placing less weight on their surgical leg compared to their non-surgical leg after surgery. This asymmetrical movement pattern has been identified by researchers and shown to not completely resolve after knee replacement surgery, even though the surgery reliably reduces knee pain. The persistence of asymmetrical weight-bearing during every day activity may limit the stimulus needed for full recovery by the muscles and joints of the surgical leg. By promoting increased loading of the surgical leg, a greater stimulus can be provided to promote better functional recovery, compared with standard rehabilitation. As a result, people may subsequently move more symmetrically with improved recovery of physical function. Improved function would in turn promote the person's ability to participate in life events, limiting disability. Considering that over 500,000 knee replacement surgeries occur in the United States each year, maximizing functional recovery and limiting disability following surgery are important goals.
