Treatment

Contents of medical treatment

We treat middle-aged and elderly patients suffering from knee joint pain and deformities.

Osteoarthritis of the knee
Rheumatoid arthritis
Spontaneous osteonecrosis of the knee
Loosening after knee arthroplasty

Surgical Treatment

Total Knee Arthroplasty (TKA)
Unilateral Knee Arthroplasty(UKA)
Around the Knee Osteotomy (AKO)
Revision TKA

Surgical Technology

1.Computer-aided 3D preoperative planning

Before surgery, we use CT and MRI to make a three-dimensional surgical plan for knee arthroplasty and osteotomy.

2.Computer navigation-assisted surgery

We achieved the ideal implant placement through accurate osteotomy and intraoperative kinetic analysis, and are able to handle a wide range of difficult surgeries.

3.Postoperative in vivo dynamic analysis

We perform dynamic analysis using 2D/3D registration technique, which estimates the 3D spatial position and posture of the artificial joint from X-ray fluoroscopic images. We are analyzing in detail how knee implants work in vivo. (ascending and descending stairs, squatting, sitting upright, walking, etc.)
