The goal of knee replacement surgery is to decrease pain and restore function. Although total knee replacement is an excellent option for patients with osteoarthritis of the knee, other surgical options exist. Patients with osteoarthritis that is limited to just one part of the knee may be candidates for uni-compartmental knee replacement (also called a “partial” knee replacement).
Uni-compartmental knee replacement is an option for a small percentage of patients with osteoarthritis of the knee. Your doctor may recommend partial knee replacement if your arthritis is confined to a single part (compartment) of your knee.
Your knee is divided into three major compartments: The medial compartment (the inside part of the knee), the lateral compartment (the outside part), and the patellofemoral compartment (the front of the knee between the kneecap and thighbone).
In a uni-compartmental knee replacement, only the damaged compartment is replaced with metal and plastic. The healthy cartilage and bone in the rest of the knee is left alone.
The revolution in uni-compartmental knee arthroplasty, is provided by customized installation guides of materials (an individualized type uni-compartmental knee arthroplasty)
Multiple studies have shown that modern uni-compartmental knee replacement performs very well in the vast majority of patients who are appropriate candidates.
The advantages of partial knee replacement over total knee replacement include:
- Quicker recovery
- Less pain after surgery
- Less blood loss
- Maintain Propioception
Also, because the bone, cartilage, and ligaments in the healthy parts of the knee are kept, most patients report that a uni-compartmental knee replacement feels more “natural” than a total knee replacement. A uni-compartmental knee may also bend better.
which can assure better alignment and proper fit to the bone in conjunction with MIS technique that gives to the patient even more benefits.
