Postoperative Care and Rehabilitation for CPM Knee Surgery
Postoperative care and rehabilitation are critical components of recovery after CPM machine-assisted knee surgery. The primary goal of postoperative care is to minimize complications, promote healing, and prepare the patient for a successful rehabilitation. Rehabilitation protocols and exercises help restore knee function, strength, and range of motion.
Postoperative Care
During the initial postoperative period, patients undergo a series of guidelines to ensure a smooth and uncomplicated recovery. The postoperative care includes:
- Monitoring of vital signs, such as heart rate, blood pressure, and temperature.
- Administration of pain management medications to alleviate discomfort.
- Application of ice packs to reduce swelling and inflammation.
- Frequent turning and repositioning to prevent pressure sores.
- Encouragement of deep breathing exercises to prevent respiratory complications.
The multidisciplinary healthcare team, including nurses and physicians, closely monitors the patient’s progress and provides guidance on postoperative care.
Rehabilitation Protocols
Rehabilitation protocols after CPM knee surgery involve a combination of physical therapy exercises, occupational therapy activities, and medical interventions. The primary objectives of rehabilitation are to restore knee function, strength, and range of motion, as well as to promote independence in daily activities.
