Total knee arthroplasty (TKA) is a viable treatment for those with end-stage degenerative changes compromising the articular cartilage affecting multiple compartments of the knee
TKA has demonstrated reproducible, long-term, successful results in such patients concerning outcomes of decreased pain and improved overall quality of life
60% of the force through the knee joint occurs on the medial tibial plateau. Thus, the medial tibial plateau is of more dense bone, and this is also why the more common wear pattern seen in osteoarthritis occurs on the medial side
In TKA recipients, muscular strength and power decrease by at least 24% when compared to the contralateral side. Experts believe more demanding rehabilitation protocols may help overcome these deficits. Recent research focuses on rehabilitation strategies that incorporate movement velocity, a component of power. Given its preferential activation of type 2 muscle fibers, high velocity (HV) exercise is thought to improve functional mobility. This form of exercise is defined as performing a muscle contraction as quickly as possible, or in 1 second or less. In contrast to HV, a LV muscle contraction is performed in two seconds or more. Evidence indicates that HV exercises can improve static and dynamic balance while decreasing quadriceps impairment
progressive resistance HV quadriceps exercises demonstrated a greater improvement in the 6-minute walk test
cryotherapy is effective in terms of the pain control and functional knee scores …
