Outcome in 12 Dogs with Chronic Radiographic Cranial Tibial Subluxation after Tibial Plateau Leveling Osteotomy (2019-2021)

Table 3

Peak vertical force and impulse gait measurements at long-term follow-up in three dogs with cranial tibial subluxation after TPLO.

Dog	PVF (N/kg) right pelvic limb	PVF (N/kg) left pelvic limb	PVF symmetry index (%)	VI (N-sec/kg) right pelvic limb	VI (N-sec/kg) left pelvic limb	VI symmetry index
2	5.22	5.67	-8.3	2.12	2.1	1.0
3	1.59	1.54	-3.2	3.2	2.76	-14.8
4	6.09	5.98	1.9	1.86	1.81	2.7

Note. PVF: peak vertical force. At long-term follow-up, dog 1 was severely lame and nonambulatory without sling support, so collection of ground reaction force data was not possible. In dog 3, standing data were obtained because the stride length and dog size were too small to obtain gait data at the trot. Index stifle treated with tibial plateau leveling osteotomy (TPLO). Symmetry index was calculated using a standard method [37].
