Partial Knee Replacement

Symptoms that may indicate the need for a partial knee replacement:

• Persistent pain in the knee, even while resting
• Stiffness in the knee that limits range of motion
• Difficulty walking or bearing weight on the affected knee
• Swelling or tenderness in the knee
• A feeling of the knee "giving out" or collapsing during use
• A visible deformity in the knee joint
• Difficulty completing everyday activities due to knee pain or stiffness
• Failure of conservative treatments, such as medications and physical therapy, to improve symptoms

The diagnosis for a partial knee replacement typically involves a physical examination and review of the patient's medical history. During the physical examination, the doctor will look for signs of osteoarthritis, such as swelling, tenderness, and deformity in the affected knee joint. They will also test the range of motion and stability of the joint.

Imaging tests, such as X-rays, MRI, or CT scans, may also be ordered to evaluate the condition of the knee joint and determine the extent of the damage. These tests can help the doctor confirm the diagnosis of osteoarthritis and assess the suitability of partial knee replacement as a treatment option.

The doctor may also ask the patient about their symptoms, including the location and intensity of the pain and how the knee pain is affecting their daily activities. This information can help the doctor determine the best course of treatment for the patient.

The treatment for a partial knee replacement typically involves a surgical procedure to replace the damaged cartilage and bone in the affected compartment of the knee with a metal and plastic implant. The implant is designed to mimic the natural movement of the knee and restore function to the joint.

The surgery is typically performed under general anesthesia and takes about two hours to complete. During the procedure, the damaged tissue is removed and the implant is carefully positioned in the knee. The surgeon will then close the incisions with sutures or staples and apply a dressing to the wound.

After the surgery, the patient will be moved to a recovery room, where they will be monitored for any complications. Physical therapy is usually recommended after the procedure to help the patient regain strength and mobility in the knee. Most people are able to return to their normal activities within a few weeks of the surgery.
