Continuous Passive Motion (CPM) devices are often used after knee surgery to gently flex and extend the joint, promoting circulation, reducing stiffness, and facilitating the recovery process. These machines are typically adjustable to accommodate individual patient needs, with parameters including range of motion, speed, and duration of treatment sessions carefully controlled. For example, a post-operative protocol might involve gradually increasing the flexion angle over several days.
Proper configuration of these parameters is crucial for maximizing therapeutic benefits and minimizing potential complications. Historically, immobilization was the standard practice following knee surgery, but CPM has emerged as a valuable tool for enhancing recovery outcomes. Optimized movement facilitated by these machines can help prevent the formation of scar tissue, improve joint mobility, and reduce pain, ultimately contributing to a faster and more complete return to function.
