The Hauser operation for patellar dislocation. 3-32-year results in 63 knees

The Hauser operation for patellar dislocation was performed in 34 women and 20 men, median age 18 (3-55) years; one leg was amputated because of wound infection with chronic septic arthritis. At the time of follow-up, 8 (3-32) years after the operation 57 knees had normal or almost normal patellar stability, but only 26 knees were free from pain. Only 16 knees had both normal patellar stability and were without pain. Patellar arthrosis had developed in 16 knees and femorotibial arthrosis in 23 knees. Eleven patients operated on before the age of 15 years showed varying grades of axial deformity of the proximal tibia.
