Final answer:
Prosthetic knee component alignment during TKR is critical and is achieved through precision surgical instruments and techniques, with verification by post-operative X-rays.
Step-by-step explanation:
The question asks whether continuous passive motion (CPM) machines are indicated for postoperative management in patients with uncomplicated total knee replacement (TKR). When performing a TKR, it is crucial that prosthetic knee components are properly aligned to ensure optimal function and longevity of the joint replacement. This alignment is commonly ensured through the use of specialized surgical instruments and techniques that allow for precise placement of the components in relation to the patient's anatomy. Computer-assisted surgery systems may also be employed to enhance accuracy. Post-operative X-rays are taken to verify the correct alignment before the patient begins rehabilitation. The use of CPM machines can vary based on surgeon preference and is subject to ongoing research regarding its efficacy in improving outcomes.
