What is the purpose of doing gentle flexion and extension within an orthosis post-op?

1. To promote aggressive healing

2. To avoid stress on the incision

3. To prepare for weight-bearing activities

4. To facilitate movement in the joint

The correct answer is: To avoid stress on the incision

The purpose of performing gentle flexion and extension within an orthosis post-operatively is primarily aimed at avoiding stress on the incision. This gentle range of motion helps to maintain mobility within the joint while the surrounding tissues are healing, minimizing the risk of complications such as excessive swelling or wound dehiscence. By allowing limited yet controlled movement, the healing process can be supported without putting undue strain on the surgical site, thus promoting a safer environment for recovery. This approach helps to ensure that the surrounding soft tissues, tendons, and ligaments do not become overly tight or restricted, which can occur if motion is completely restricted for an extended period. In the postoperative context, promoting aggressive healing or preparing for weight-bearing activities typically occurs later in the rehabilitation process once the incision has sufficiently healed. Facilitating movement in the joint is an outcome of the gentle flexion and extension but is not the primary goal within the early phases post-surgery, where incision protection is critical.
