Internal fixation for fractures of the patella. A comparison of two methods

Cadaveric experiments in 10 knees were used to study the strength of two methods of internal fixation for a fractured patella. A modified AO tension band technique was compared with the combination of cerclage wiring and a tension band used at Pyrford. The repairs were stressed to failure; the combination of cerclage and tension band wiring proved to be significantly stronger and is recommended.
