Total Hip Arthroplasty
Also written as: THA — Total Hip Arthroplasty
Surgical replacement of hip joint with prosthetic components, requiring specific rehabilitation protocols.
Full Definition
Total Hip Arthroplasty (THA), also known as total hip replacement, is a surgical procedure that replaces the damaged hip joint with prosthetic components including a femoral stem, acetabular cup, and bearing surface. Rehabilitation following THA involves specific precautions to prevent dislocation, including avoiding hip flexion beyond 90 degrees, internal rotation, and adduction past midline. The approach used (posterior, anterior, or lateral) influences precautions and recovery timeline. Physical therapy focuses on gait training, strengthening, and functional mobility while adhering to weight-bearing restrictions.
Usage
Usage note: Specify surgical approach when relevant to rehabilitation planning; distinguish from revision procedures.
