Plain-English summary
A group of 23 dogs underwent total hip replacement surgery using a new type of implant designed to reduce complications. After a follow-up period of about 17.5 months, some dogs experienced issues, with seven hips having complications, including two that needed to be removed. However, the majority of the implants remained in place without significant problems, and there were no cases of loosening over time. Overall, this new implant appears to be a good option for dogs needing hip surgery, with a complication rate similar to other systems.

Abstract
OBJECTIVE:  The aim of this study was to report complications and outcomes of a cementless total hip arthroplasty (THA) system with a second-generation selective laser-melted screw cup (SCSL). STUDY DESIGN:  All THA using the SCSL performed at a single institution between January 2017 and November 2022 were retrospectively evaluated. Patients with a minimum follow-up period of 12 months and complete medical records were included and analyzed for radiographic and clinical outcomes. RESULTS:  Thirty THA with SCSL in 23 dogs were included in this study. Complications were observed in seven hips, comprising two minor and five major complications, with two hips experiencing two major complications. Among these seven major complications, six were associated with the femoral implant and one involved cup luxation. Of the 30 THA, 4 were explanted, while 26 remained in place for a median follow-up of 17.5 months (range, 12-38 months). CONCLUSION:  No cases of late aseptic loosening were observed with SCSL. THA using SCSL helps reduce cup-associated complications and is appropriate for THA surgery, and the overall complication rate is comparable with that of other single-implant systems. Nevertheless, four hips were explanted.
