Name of the Procedure:

Continuous Passive Motion (CPM) Exercise Device for Knee (E0935)

Summary

The Continuous Passive Motion (CPM) exercise device is specifically designed for the knee. It helps patients recover mobility and flexibility in their knee joint by gently and continuously moving the knee through its range of motion without the patient needing to actively use their muscles.

Purpose

The CPM device is primarily used to help patients recover from knee surgery or injury. It aims to reduce stiffness, improve knee joint mobility, prevent scar tissue formation, and enhance overall recovery outcomes by maintaining gentle movement in the knee.

Indications

• Post-operative recovery from knee surgeries such as total knee arthroplasty (TKA) or knee ligament reconstruction.
• Stiffness or limited range of motion in the knee joint.
• Conditions like osteoarthritis or rheumatoid arthritis that affect knee mobility.
• Patients who require assistance with knee movement to avoid muscle atrophy and joint stiffness.

Preparation

• No special fasting or dietary restrictions are needed.
• Patients should inform their healthcare provider about all medications they are taking.
• Diagnostic imaging (e.g., X-rays or MRIs) may be conducted in advance to assess the knee condition.

Procedure Description

1. The patient is positioned comfortably, with their knee resting on the CPM device.
2. The device is adjusted to fit the patient's leg and set to the desired range of motion.
3. The device then gently moves the knee joint through a preset arc of motion continuously.
4. The procedure is typically repeated several times a day, as recommended by the healthcare provider.

Tools and Equipment Used

• Continuous Passive Motion (CPM) device specifically designed for the knee.

Anesthesia or Sedation

• No anesthesia or sedation is required.

Duration

Each session usually lasts about 1-2 hours, depending on the physician's recommendations and patient tolerance.

Setting

The procedure can be performed in various settings:

• Hospitals
• Outpatient clinics
• At home, under the guidance of a healthcare provider

Personnel

• Physical therapists
• Nurses
• Physicians (to prescribe and set up the device)

Risks and Complications

Common Risks:

• Mild discomfort in the knee
• Skin irritation from the device

Rare Risks:

• Increased pain or swelling in the knee
• Potential for mechanical failure of the device

Complications are generally rare and can be managed by adjusting the device settings or discontinuing use.

Benefits

• Improved knee joint mobility and flexibility.
• Reduction in post-operative stiffness and pain.
• Prevention of scar tissue formation.
• Enhanced overall recovery time.

Benefits can often be realized within a few weeks of consistent use, although this may vary based on individual patient factors.

Recovery

• Follow post-procedure care instructions provided by the healthcare provider.
• Continue regular sessions as recommended.
• Avoid strenuous activities until cleared by the healthcare provider.
• Schedule follow-up appointments to monitor progress.

Alternatives

• Traditional physical therapy exercises.
• Manual manipulation by a physical therapist.
• Use of mobility aids like canes or walkers.

Pros and Cons of Alternatives

Pros:

• Manual therapy and traditional exercises can be tailored to patient needs.
• No mechanical device is required.

Cons:

• May not provide the same consistency and continuous motion.
• Requires more active patient participation and can be more exhausting.

Patient Experience

Patients may feel a gentle, continuous movement in their knee joint during the procedure. Some initial discomfort might be present but tends to decrease with regular use. Pain management strategies, such as over-the-counter pain relievers or prescribed medications, can be used if necessary. The device can provide comfort and aid in a more rapid return to daily activities.
