 Currently in the United States, more than 700,000 total knee arthroplasty TKA surgeries are performed annually, with projections of 3.5 million performed annually by 2030. The increasing incidence of TKA comes with an immediate need for establishing optimal rehabilitation guidelines to remediate common post-TKA physical impairments and improve functional outcomes. Over the past decade, a primary focus of the investigators TKA rehabilitation research has been on progressive strengthening, which improves muscle strength and physical function, and is now the contemporary approach to TKA rehabilitation. However, a major issue remaining for patients rehabilitating from unilateral TKA is the persistence of atypical movement patterns. These atypical movement patterns, observed during walking and other functional tasks, are characterized by disuse of the surgical limb, resulting in smaller knee extension moments on the surgical limb compared to the non-surgical limb. As a result, atypical movement patterns following unilateral TKA are associated with persistent quadriceps weakness and poor physical function.
