The results of partial patellectomy as a treatment for displaced patellar
fractures were assessed retrospectively with use of clinical, radiographic,
and isokinetic strength-testing criteria. Forty patients who had been
followed for an average of 8.4 years were studied. In the extremity that
had been operated on, the mean active range of motion was 94 per cent, the
circumference of the thigh was 100 per cent, and the strength of the
quadriceps was 85 per cent of these measurements in the contralateral
extremity. The over-all result was rated as excellent in twenty patients,
good in eleven, fair in six, and poor in three. There was a significant
statistical correlation between the type of fracture and the outcome. The
results of this study indicate that partial patellectomy can be an
effective treatment for selected patellar fractures.
