Abstract
Total knee arthroplasty (TKA) is a common treatment for osteoarthritis of the knee joint. A decrease in lower extremity power is commonly seen in older adults who have knee osteoarthritis and TKA. This review integrates the current evidence regarding the change in lower extremity muscle power following TKA, rehabilitation efforts to improve power following TKA, and changes in muscle power related to function after TKA. It is recommended that lower extremity muscle power be measured and rehabilitated appropriately following TKA. A need for future research examining best treatment protocols to develop lower extremity power after TKA is warranted.
