As medical technology continues to evolve, orthopaedic surgery has entered a new era of precision and preservation. Among these advancements, Microplasty — a modern technique for partial knee replacement — has emerged as a game-changer for patients suffering from early or localized knee arthritis. It combines minimally invasive surgical methods with robotic precision to restore mobility while preserving natural bone and joint function.
Microplasty is an advanced form of partial (unicompartmental) knee replacement that focuses only on replacing the damaged portion of the knee while leaving healthy bone, cartilage, and ligaments untouched. It is typically recommended for patients who have arthritis confined to one area of the knee — either the inner (medial) or outer (lateral) compartment — rather than the entire joint.
Unlike total knee replacement, where the entire joint surface is replaced, microplasty targets only the affected region. This approach allows for smaller incisions, faster recovery, and more natural knee movement post-surgery.
In traditional knee replacement, both sides of the joint are replaced, even if only one side is damaged. Microplasty challenges this “one-size-fits-all” approach by addressing only the problematic section. The result is a less invasive surgery, reduced trauma to surrounding tissues, and preservation of the knee’s original ligaments and mechanics.
When performed using robotic or computer-assisted guidance, Microplasty ensures **unmatched precision in implant positioning**, alignment, and balancing. The robotic system assists the surgeon in planning the procedure with sub-millimeter accuracy, leading to better joint function and longer implant lifespan.
Microplasty is best suited for patients who:
It is often ideal for younger or more active patients with early-stage arthritis who wish to maintain a high level of mobility.
Robotic-assisted Microplasty elevates the precision and outcome of partial knee replacement. Using a 3D model of the patient’s knee, the robotic system helps the surgeon plan every step of the procedure in advance. During surgery, it guides the instruments in real-time, ensuring perfect alignment, balance, and fit of the implant — all while protecting healthy structures around the knee.
This level of accuracy not only enhances implant durability but also improves overall comfort and motion after recovery. Patients typically report a faster return to daily activities and a more “natural” knee feel compared to conventional methods.
Most patients are able to walk within a day or two after microplasty and resume normal activities much faster than those undergoing total knee replacement. Structured physiotherapy plays a crucial role in strengthening muscles, restoring balance, and maximizing movement. Because the surgery preserves much of the joint’s natural anatomy, recovery tends to be smoother and more comfortable.
The demand for minimally invasive and bone-preserving treatments is rising, and microplasty fits this vision perfectly. It blends technology, surgical skill, and patient-centric care — offering a highly personalized alternative to conventional knee replacement. As robotic systems and regenerative techniques continue to evolve, microplasty will become the standard for patients seeking precision-based joint preservation and mobility restoration.
Microplasty represents the future of partial knee replacement — combining the best of advanced technology, minimal invasiveness, and biological preservation. For individuals looking to stay active and avoid total joint replacement, this procedure offers the perfect balance between relief, function, and longevity.
