Objective To determine the influence of postoperative extracorporeal shock wave therapy (ESWT) on hind limb use after tibial plateau leveling osteotomy (TPLO). Study design Randomized, prospective clinical trial. Animals Sixteen client‐owned dogs, 2 to 10 years old weighing 18 to 75 kg. Methods Dogs were randomly assigned to treatment cohorts, TPLO with ESWT (ESWT, n = 9) or TPLO without ESWT (control, n = 7). Treatment consisted of 1000 pulses at 0.15 mJ/mm 2 immediately and 2 weeks after surgery. Subjective pain, stifle goniometry, stifle circumference, peak vertical force (PVF) and vertical impulse (VI) were measured before surgery, prior to ESWT, and 2 and 8 weeks after surgery. Measures were compared between treatments at each time point and among time points for each treatment ( P < .05). Results The PVF (5.5 ± 1.0 N/kg, mean ± SD) and VI (0.67 ± 0.14 N‐s/kg) of surgically treated limbs in the ESWT cohort were higher 8 weeks after surgery compared with preoperative (3.8 ± 1.1 N/kg, P < .0001 and 0.47 ± 0.21 N‐s/kg, P = .0012, respectively) values. In the control cohort, PVF (2.9 ± 1.3 N/kg, P = .0001) and VI (0.33 ± 0.20 N‐s/kg, P = .0003) 2 weeks after surgery and VI (0.42 ± 0.2 N‐s/kg, P = .0012) 8 weeks after surgery were lower (4.59 ± 2.33 N/kg and 0.592 ± 0.35 N‐s/kg, respectively) than before surgery. Other parameters did not differ between groups. Conclusion Weight bearing increased faster after TPLO in dogs treated with postoperative ESWT. Clinical significance This study provides evidence to consider adjunct ESWT after TPLO.
