[Gonarthrosis and empyema in geriatric patients. Combined synovectomy and KTEP implantation procedure].

ISSUE: Is a one stage procedures with open synovectomy and implantation of cemented knee endoprostheses in patients with empyemas of the knee and concomitant osteoarthritis suitable to reduce morbidity and increase early mobility?

METHOD: Three female patients (age [symbol: see text] 88 yrs.) with acute empyema of arthritic knee joints (Pathogen: Staph. aureus) were treated with open synovectomies and implantations of cemented TKA's in a one stage procedure at mean 3 days (1-6) after admission. After 4.6 months (3-6) we carried out the last clinical and radiographic examination and after 15 months (11-21) a telephone questionnaire.

RESULTS

The mean operation time was 2.4 hrs. (2-3), the perioperative blood loss at mean 1040 cc (800-1180 cc) and patients received 4 units blood (4-5). Parenteral antibiotics were administered for at mean 21 days (18-25 d). 33 days (27-39) after surgery the patients could be discharged, all of them ambulated with a walker, the operated joints had no signs of infection and blood parameters i.e. leucocyte count, crp and ESR dropped. At the time of the latest follow up examination there were neither clinical nor radiographic any signs that infections recurred. Two patients ambulated with crutches, one still with a walker. The HSS-Score increased from preop. 54 pts. up to 80 pts. at the follow up.

CONCLUSION

Due to our results, a one stage procedure with open synovectomy and implantation of cemented total knee endoprostheses seems to be a considerable alternative for the treatment of geriatric patients suffering from knee empyema and severe osteoarthritis.
