Unicondylar Knee Arthroplasty

One of the main reasons why we surgeons prefer to avoid total knee replacement surgery in relatively young patients is related to the fact that given enough time all joint replacement surgeries are candidates for revision. As being longer and technically more demanding revision knee replacement surgery can be challenging both for the surgeon and the patient. So sparing the total knee replacement surgery for after the age of 65 generally means that the patient either will not need a revision or need at most a single revision will be enough for the rest of their life. 

Unicondylar knee replacement surgery and implants were designed with the goal to minimize the challenges of the first revision surgery if and when needed with even better comfort tolerance and function when compared to total knee replacement. Thus these benefits make it a feasible option for the younger arthritis patient. Since it only resurfaces a single compartment in the knee as opposed to 3 compartments in total knee replacement the design of unicondylar knee implants is far more gentle and sleek. During the surgery this unique design enables it to be implanted in the bone with minimal bone cuts thus preserving as much bone as possible. 

The bone loss after a unicondylar knee surgery is generally so minor, as a result when a revision is required regular primary total knee implants can be implanted with general ease instead of bulky revision implants. Addressing most of the challenges of receiving a joint prosthesis at younger ages the unicondylar knee replacement helps younger arthritis patients to return to quality life without compromising future surgical options. 

Ideal implant positioning and alignment are fundamental in unicondylar arthroplasty to obtain the longest possible implant lifespan. So if you prefer robotic-assisted unicondylar surgery can be a good option to further reduce the risk of malpositioning.
