Due to the lateral dislocation of the patella at grade four, it was decided to undergo PGRsurgery for treatment. During the operation, the BlueSAO press-fit biological pulley groove replacement system (PGR) #2 implant was used for replacement. The operation was successfully completed. Hope you recover soon!

Thanks forDr.Zhou Xingzhao of Shenzhen Xingzhao Bone Specialized Pet Hospital for sharing the clinical case of the BlueSAO biological Press-fit PGRsystem!

The PGR surgery will bring a painless joint to patients with patellar dislocation.


Doctor Jia Xinsheng's view is that the PGR surgery will bring a painless joint to patients with patellar dislocation, and he suggests that the PGR surgery be adopted for eligible cases of patellar dislocation. For instance, cases where the patella flat, deformed, underdeveloped, too narrow, or where the veterinarian's assessment of the deepening of the patella groove fails to yield effective results, etc., all recommend the use of patella groove replacement surgery (PGR).
