Pre-operative image of a 67-year-old male patient with progressively worsening left-sided knee pain that is localized to the inner aspect of the right knee. The knee X-ray demonstrates full-thickness cartilage loss in the medial compartment that is bone-on-bone. The remainder of the knee is unaffected.
The patient has now undergone a left medial unicompartmental knee replacement. The new partial knee implant resurfaces the damaged medial compartment, while leaving the patient’s normal lateral and patellofemoral compartments intact.
