Abstract:

BACKGROUND: In recent decades, total knee arthroplasty is widely used in the treatment of terminal knee joint diseases, such as osteoarthritis, rheumatoid arthritis, traumatic arthritis and other bone diseases. The methods of osteotomy, soft tissue balance and prosthesis rotation positioning have always been debated and discussed in total knee arthroplasty.
OBJECTIVE: To explore the repair effect of total knee arthroplasty for terminal knee disease.
METHODS: Total knee arthroplasty was performed for treating terminal knee disease in 31 cases (31 knees), including 26 cases of osteoarthritis (26 knees) and 5 cases of rheumatoid arthritis (5 knees). All cases accompanied flexion contracture deformity to different degrees. The maximum angle of flexion deformity was    < 25°. All patients were scored by hospital for special surgery knee score before and after replacement. All 31 knees were treated with fixed platform posterior-stabilized prostheses.
RESULTS AND CONCLUSION: No complications, such as early infection and prosthesis dislocation, were found after surgery. Joint pain apparently lessened, flexion and varus deformity obviously improved after replacement. Postoperative X-ray films showed good prosthesis position and low limb alignment. All cases were followed up for 6-12 months. The hospital for special surgery knee score improved significantly from preoperatively 46.4±5.3 to postoperatively 84.6±10.5 after 6 months of follow-up. Excellent and good rate was 84%. Results indicate that total knee arthroplasty for treating terminal knee disease has a good clinical effect. However, the operation is complex and precise technique is required.
