Surgical Cases

Pre-operative image of a 52-year-old female patient with severe right-sided knee pain, localized to the inner aspect of the right knee. The standing knee X-ray demonstrates full-thickness cartilage loss that specifically involves the medial compartment, with an associated varus (bow-legged) deformity. Post-operative image shows the patient has now undergone a right medial unicompartmental knee replacement via robotic-arm assistance, with anatomic component positioning and restoration of the native knee alignment.

Pre-operative image of a 54-year-old male patient with longstanding right-sided hip pain. The pelvic X-ray demonstrates full-thickness cartilage loss, with periarticular bone spurs and deformity of the femoral head. Post-operative image shows the patient has now undergone a right total hip replacement through a direct anterior approach, with anatomic component positioning and restoration of his native hip length and offset.

Pre-operative image of a 78-year-old female patient with longstanding left-sided knee pain and a valgus (knock-knee) deformity. The knee x-ray demonstrates tricompartmental osteoarthritis with progressive cartilage loss that is most severe in the lateral compartment. In the post-operative image, the patient has now undergone a left total knee replacement. The new knee prosthesis restores the knee back to normal mechanical alignment and is well-balanced in flexion and extension using a gap-balancing technique.

Pre-operative image of a 65-year-old male patient with progressively worsening right-sided knee pain that is localized to the inner aspect of the right knee. The knee X-ray demonstrates a focal area of osteonecrosis with full-thickness cartilage loss in the medial femoral condyle. The remainder of the knee is unaffected. The post-operative image shows the patient has now undergone a right unicompartmental knee replacement. The new partial knee implant resurfaces the damaged medial compartment while leaving the patient’s normal lateral and patellofemoral compartments intact.

Pre-operative image of a 60-year-old male patient with longstanding right-sided knee pain and a varus (bow-legged) deformity. The knee X-ray demonstrates tricompartmental osteoarthritis with progressive cartilage loss that is bone-on-bone in the medial compartment.

The patient has now undergone a computer-navigated right total knee replacement. The new knee prosthesis restores the knee back to normal mechanical alignment, and is well-balanced in flexion and extension using a gap-balancing technique.

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.

Pre-operative image of a 33-year-old male patient with longstanding right-sided hip pain, stiffness, and chronic shortening of the limb. The hip X-ray demonstrates avascular necrosis with complete collapse of the femoral head and destruction of the articular cartilage.

The patient has now undergone a right total hip replacement through a direct anterior approach, with anatomic component positioning and restoration of his native hip length and offset.
