EARLY RESULTS FROM HIP ARTHROPLASTY USING CEMENTLESS ACETABULAR COMPONENT ALLOFIT PRESS-FIT

We present early and first decade results in patients with primary and revision total hip arthroplasty (THA) using an uncemented acetabular press-fit cup (Allofit; Zimmer Inc., Warsaw, IN). We examined 30 clinical cases using this implant and achieved very good to excellent results. We correlate our results with the Allofit acetabular cup’s primary stability. We believe that the Allofit press-fit cementless acetabular component is an excellent alternative to cemented implants in regards to the stability of the acetabular cup in primary total hip arthroplasty, as well as selected revision hip arthroplasty cases. Purpose: Our purpose is to showcase our results using the Allofit acetabular cup in a study that included 30 cases. Material and methods: Over the period from 2018 to 2022 in our clinic - 30 hip arthroplasties were performed using the Allofit press-fit implant. In all clinical cases, the patients were verticalized on the second postoperative day and early ambulation, and physiotherapy was instituted with partial involvement of the replaced hip. There were no complications or instability in any of our primary THAs. Results: We examined 30 clinical cases over the period of 48 months. There were no complications due to surgical technique, as well as no pathological X-ray findings. We correlate these results with the Allofit acetabular cup’s primary stability. Conclusions: We believe that the Allofit press-fit cementless acetabular component is an excellent alternative to cemented implants in regards to the stability of the acetabular cup in primary total hip arthroplasty, as well as selected revision hip arthroplasty cases.
