Partial knee replacement, also known as unicompartmental knee replacement, is a surgical procedure used to replace only the damaged compartment of the knee, preserving healthy bone and tissue.
1
Preparation
Before surgery, anaesthesia is administered to ensure the patient's comfort.
2
Incision
A smaller incision is made compared to total knee replacement, focusing on the affected compartment of the knee.
3
Resurfacing
The damaged cartilage and bone in the affected compartment are removed, and the remaining bone surfaces are shaped to accommodate the prosthetic implant.
4
Implant Placement
A partial knee prosthesis, consisting of metal and plastic components, is securely attached to the prepared bone surfaces.
5
Closure
The incision is closed, and the knee is stabilized.
Partial knee replacement preserves healthy bone and tissue in the unaffected compartments of the knee. The procedure typically involves a shorter hospital stay and faster recovery compared to total knee replacement. Patients often report a more natural feeling in the knee compared to total knee replacement. With less disruption to surrounding soft tissues, patients may experience reduced post-operative pain and swelling. This approach can also lead to improved joint function and a quicker return to normal daily activities.
Physical Therapy
Rehabilitation focuses on strengthening the knee muscles and restoring range of motion.
Activity Modification
Patients may need to avoid high-impact activities and excessive stress on the knee joint during the early stages of recovery.
Follow-up Appointments
Routine follow-up visits with the surgeon are scheduled to monitor joint function, assess implant stability, and address any concerns or complications.
