Knee Resurfacing / Partial Knee Replacement

Knee Resurfacing / Partial Knee Replacement

Partial knee replacement, as the name suggests, is the substitution of a part of a knee with a prosthetic through surgery. If only one part is to be resurfaced then it is known asnoncompartmental knee replacement. It is done when the arthritis is limited to one compartment of the knee; the medial part, the lateral part of the kneecap.

During partial knee replacement surgery, the damaged bone and cartilage are replaced with man-made plastic or metallic parts. The anterior and posterior ligaments are preserved. The medial part that is the inner one, is by far the most common part that is replaced partially.

 

Benefits of Partial Knee Replacement:

There are benefits to this type of surgery over total knee replacement.

    • It’s a smaller operation, therefore, the recovery is quicker
    • Patients tend to get a better range of movement and better function
    • It’s a less invasive surgical treatment option
    • There is less blood loss and less pain after surgery
    • It allows the patient to keep more of their own bone and cartilage
Risks associated with Partial Knee Replacement:

There are downsides to partial knee replacement, and the redo rate is certainlyhigher than full knee replacement. The knee function may also worsen after revisionof the replacement.

Types of patient most suited toPartial Knee Replacement:

Partial knee replacement is appropriate for patients of ages older than 60 years,weighing less than 180 lbs. with less activity and minimal deformities. Youngerpatients with a higher level of activity and function before surgery are also suitable.

In cases with rheumatoid arthritis, the inflammation is spread to more than onecompartment so patients with such arthritis are not eligible for this surgery.

Selection of the right patient and the presence of an experienced surgeon for thisprocedure is essential for the successofpartial knee replacements.
