Complications following total knee replacement

Abstract

Forty-two months follow-up examinations on 30 total knee arthroplasties revealed the following significant complications: phlebothrombosis, 13 knees (46%); pulmonary embolism 3 patients (11%); asymptomatic loosening, 8 knees (11.4%); symptomatic loosening, 3 knees (4.8%); superficial infections, 4 knees (5.4%); deep infections, 4 knees (5.4%); peroneal palsy, 3 patients (4.3%). Early detection of thrombophlebitis by 125I fibrinogen scan and possible aspirin prophylaxis were evaluated. In view of the limited number of encouraging results, e.g. excellent 58.6 per cent; good 28.5 per cent; fair 5.4 per cent and poor 7.1 per cent, caution is advocated until extensive time elapses for more clinical experience with total knee arthroplasty.
