➤ In 2013, 662,545 total knee arthroplasties (TKAs) were performed, making it the
most commonly performed orthopedic surgery in the lower extremity.
➤ The number of TKAs performed annually in the United States is expected to
increase by 855% between 2012 and 2050, equating to 2,854 procedures per
100,000 US citizens over 40 years of age.
➤ Globally hip and knee OA was ranked as the 11
th
highest contributor to disability
among almost 300 health conditions.
➤ TKA consists of resection of the diseased or degenerative articular surfaces
of the knee, replacing the surface with metal and polyethylene prosthetic
components.
➤ The clinical practice guideline is based on a systematic review of published
studies with regard to the physical therapist management of patients undergoing
TKA and is an educational tool to guide qualified clinicians through a series of
treatment decisions in an effort to improve the quality and efficiency and reduce
unwarranted variation of care.
➤ This pocket guide addresses the physical therapist management of adult patients
with knee osteoarthritis undergoing primary TKA. It is not intended to address
management of revision or partial TKA, pediatric patients, or patients with
rheumatoid arthritis. In addition, this pocket guide is not intended to address
nonoperative management of patients with osteoarthritis.
