In this study, total hip replacement (THR) was performed by using implants from the Innoplant company on 30 dogs and 33 cases. The average weight of the dogs was 33.05 ± 11.15, and their age range was approx. 26.6 months. The breed distribution among the cases was: Golden Retriever (n=5), German Shepherd (n=2), Rottweiler (n=4), Kangal (n=3), Labrador Retriever (n=5), Mixed Breed (n=4), Alabay (n=1), Chow Chow (n=1), Border Collie (n=2), Samoyed (n=1), and Bulgarian Shepherd (n=2). About 57% of the cases had bilateral hip dysplasia, 37% had coxarthrosis, 3% had hip luxation, and 3% had excisional arthroplasty findings. In our study, both porous and non-porous screw cups and stems of the Innoplant brand were used, while complications occurred in 10 cases. Two of these complications happened during the operation, while 8 occurred after the operation. Of these complications, 9 were classified as major, and 1 was classified as minor. The complications observed including femoral fractures (n=2), stem subsidence (n=3), stem loosening (n=1), cup loosening (n=2), cup dislocation (n=1), and loosening in both the stem and the cup (n=1). In 4 of these cases, the prosthesis was completely removed, while revision surgery was performed in 6 dogs. The long-term results of the 6 revised cases were evaluated as very good. The time until the patients could place their foot on the ground after the operation was 24 hours for 11 cases and 36 hours for 20 cases. In conclusion, the cementless Innoplant prosthesis system used for THR, is a viable prosthetic technique with a low complication rate which provides successful clinical and radiographic outcomes over an average period of 31 months.
