| Popis: | We report long-term results (over 10 years) of total knee arthroplasty (TKA) for the treatment of osteoarthritis (OA) and rheumatoid arthritis (RA). Twenty-three patients (OA; 10 patients, RA 13 patients) with 36 knees were examined. Clinical results were evaluated using the Knee Function Scoring System developed by three universities. Radiographs were evaluated for the loosening and sinking of TKA. Post-operative complications were evaluated in 79 knees of 49 patients.The function score significantly improved from 41 to 73 points in patients with OA and from 40 to 63 points in patients with RA. In both OA and RA knees, the extension of the knee joint improved after surgery and was maintained at follow-up. Positive correlation was found between the knee flexion angle before surgery and that at follow-up. In radiographic evaluation, only 1 sinking was found in OA, whereas, 2 loosening and 4 sinking were found in RA. Postoperative complications were 1 infection in OA, whereas, 7 aseptic loosening, 2 infections, and 1 posterior dislocation were seen in RA, indicating better functional recovery with less complication can be expected in OA patients than in RA patients. Better flexion of the knee joint can also be expected if TKA is performed before contracture of the knee joints develops. |
