Tibial tuberosity conformation as a risk factor for cranial cruciate ligament rupture in the dog.

Koch & Bass Referral Practice for Small Animal Surgery, Basadingerstrasse 26, 8253 Diessenhofen, Switzerland. info@kochbass.ch
2009
The influence of the tibial tuberosity conformation on cranial cruciate ligament (CrCl) rupture was evaluated and the size of the tibial tuberosity of healthy dogs (group H) was compared with dogs with CrCl rupture (group R) and dogs treated by tibial tuberosity advancement (TTA) (group T). The medio-lateral radiographs of 219 stifle joints were evaluated. Relative tibial tuberosity width (rTTW), proximal tibial tuberosity angle (PTTA), tibial plateau angle (TPA), tibial width (TW) and tibial plateau length (TPL)…
