Objective To determine if shock wave therapy ( SWT ) after tibial plateau leveling osteotomy ( TPLO ) has a beneficial effect on patellar ligament inflammation assessed by thickening of the ligament and ligament fiber disruption. Study Design Prospective, randomized, controlled clinical trial. Animals Dogs (n = 30). Materials and Methods Dogs that had TPLO (July 1, 2009 to June 1, 2010) were enrolled. The affected stifle was examined by radiographs and ultrasonography preoperatively and 4, 6, and 8 weeks after TPLO . At 4 and 6 weeks, dogs in the treatment group were briefly anesthetized and treated with SWT . Patellar ligament thickness on a lateral radiographic projection was measured at 1/4, 1/2, 3/4 of the distance from origin to insertion. Ultrasound images were evaluated for patellar ligament disruption and periligament edema. Results There was significant difference in thickness ( P = .0264) only at the distal point; therefore, only this point was used to measure difference between the control and treatment groups. A significant difference between groups was reached at 6 and 8 weeks ( P = .0059 and P = .0095, respectively) postoperatively. No significant ultrasonographic differences were found. Conclusion Based on these results, SWT decreases the radiographic signs of patellar ligament desmitis.
