Summary: This study compared the degree of stem subsidence between two different femoral component designs in Dorr type C femurs after cementless total hip arthroplasty. The results showed that the tapered wedge stem was more suitable than the fit-and-fill stem to avoid early postoperative subsidence in Dorr type C femurs.

Summary: The study compared short and standard-length tapered-wedge femoral stems in single-stage bilateral total hip arthroplasty through a direct anterior approach. Results showed no significant differences between the two groups in terms of surgical outcomes, but the short-stem group had a significantly higher canal fill ratio at the level of the lesser trochanter compared to the standard-length-stem group.

Summary: This study aimed to determine the optimal femoral canal contact regions to reduce stress shielding in cementless short, tapered-wedge stem total hip arthroplasty (THA). Through radiographic and 3D computed tomography analysis, it was found that a mediolateral fit with the most proximedial calcar site restricted fitting was the best for reducing stress shielding.

Summary: This study aimed to determine the minimum 20-year survival rates of a cementless press-fit cup in young patients. The results showed that the 22-year survival rate for aseptic cup or inlay revision was 94%, and the survival rate for aseptic cup loosening was 99%.

Summary: This study retrospectively analyzed medical records of 230 patients who underwent total hip arthroplasty (THA) and found that misalignment and improper seating of short tapered stems may lead to thigh pain postoperatively.

Summary: This study evaluated the outcomes and complications of revision total hip arthroplasty in a short-to-medium follow-up period. A total of 31 patients who underwent stem revision with a fluted, tapered modular stem were reviewed. The survival rate was 100%, and there were no re-revisions. The Harris hip score improved significantly after surgery.

Summary: This study compared the effectiveness of two different geometric designs for total hip arthroplasty (THA). The results showed that compared to double-wedge designs, single-wedge designs were more prone to revision due to aseptic loosening. Therefore, femoral stem geometry should be considered when selecting a cementless femoral implant.

Summary: This study aimed to determine the learning curve for short-stem total hip arthroplasty through an anterolateral approach among five residents in training. The surgical time was the only parameter that showed a significant improvement. Only two of the five residents showed significant improvements in all examined surgical parameters. Individual differences in learning abilities were observed among the residents.

Summary: The posterolateral approach in total hip arthroplasty can lead to degeneration of the internal and external obturator muscles, while the anterolateral approach is more beneficial for recovering the gluteus medius, tensor fasciae latae, and internal obturator muscle.

Summary: The study found that the prevalence of revision for periprosthetic femoral fracture (PFF) was higher in patients with the CPT stem compared to the Exeter stem. It is recommended to consider alternative cemented stems for patients at high risk for PFF.

Summary: A retrospective study compared the early postoperative outcomes of minimally invasive total hip arthroplasty between anterolateral and posterolateral approaches. The surgical time was longer in the posterolateral group, and the C-reactive protein level was higher in the posterolateral group only on postoperative day 3. There was no significant difference in the recovery rate of muscle strength between the two approaches.

Summary: This study compared radiographic and digital tomosynthesis assessments of early biological fixation of a cementless stem in primary total hip arthroplasty. It was found that digital tomosynthesis could detect biological fixation earlier than radiography, with fixation potentially occurring within 3 months postoperatively.

Summary: The aim of this study was to evaluate the impact of different types of cementless stems on patient quality of life and patient-reported outcomes (PRO), and to clarify the relationship between PRO and stem-cortical bone contact. The study included 138 patients undergoing cementless total hip arthroplasty. The results showed no significant differences in PRO between stem types according to the JHEQ and patient's joint perception. Patients with a taper wedge stem had a higher frequency of peri-hip articular joint pain (PHAP) compared to those with a fit-and-fill stem. Distal contact was associated with PHAP in both groups, but not with JHEQ results and patient's joint perception.

Summary: This study retrospectively evaluated the survivorship and clinical outcomes of the TRI-LOCK BPS, a proximally coated, tapered-wedge femoral stem. The results showed excellent construct and stem survivorship, as well as clinical outcomes, at intermediate-term postoperative follow-up.

Summary: In this study, differences in tapered wedge stem alignment between supine and lateral positions in total hip arthroplasty were explored under the modified Watson-Jones approach. While the coronal plane alignment did not show significant differences between groups, a tendency towards flexed implantation was observed more in the supine group. Additionally, there was a significant correlation between femoral anteversion and stem anteversion in both supine and lateral positions.
