Early motion after arthroplasty.

Author information

Jefferson Medical College of Thomas Jefferson University, Philadelphia, Pennsylvania, USA.


Early controlled motion after arthroplasty in the MP and PIP joints allows for collagen remodeling during the encapsulation process that creates a stable joint. Motion generally is begun within the first few days after surgery and must be supervised carefully. Dynamic splinting is an important component in achieving early motion in the MP joints and often is a useful adjunct in the PIP joints. Early motion after total wrist arthroplasty depends on surgical fit of the prosthesis. Only a tight fit allows early motion. The potential for complications resulting from early motion in the wrist is greater than in the MP or PIP joints and may involve increased wear, fracture, or component loosening. The benefits of early motion after arthroplasty, therefore, must be weighed against potential risks. Although generally necessary in the MP and PIP joints to achieve satisfactory results, early motion after total wrist arthroplasty has limited applications and significant risks.
