Frequent complications of deficient patellae after component removal in 1.5-stage exchange arthroplasty for periprosthetic joint infection.
To compare the complication rates between deficient patellae (remnant patellae after component removal) and non-resurfaced patellae after 1.5-stage exchange arthroplasty for periprosthetic joint infection and identify risk factors for complications of deficient patellae. ⋯ III.

Displaced dorsal rim fragment in distal radius fracture: what is the size threshold for compromise?
This study aimed to explore the effect of displaced dorsal rim fragments under defined size threshold on the clinical outcome. ⋯ For dorsal rim fragments comprising less than 10% of the radiocarpal articular surface in distal radius fracture, mild displacement does not significantly affect the recovery of wrist function.

Short-term prediction of clinical and radiographic contralateral hip osteoarthritis after index total hip arthroplasty.
Patients with primary hip osteoarthritis undergoing unilateral total hip arthroplasty (THA) often face uncertainty about the future need for arthroplasty in the contralateral hip. We aimed to identify parameters that have predictive value with regard to the necessity for contralateral THA or the development of contralateral radiographic osteoarthritis (OA) phenotypes following index surgery. ⋯ Three factors - BMI, alpha angle, and osteophyte number - are key short-term predictors for contralateral THA after index THA. We also identified BMD as a surrogate for osteophyte formation. These findings provide novel and valuable insights for patients and surgeons regarding risks and counseling for contralateral OA and THA.

Impact of the difference between preoperative planning and intraoperative femoral neck osteotomy level on stem alignment.
The combined anteversion theory is used for implant placement in total hip arthroplasty (THA). While majority of the research emphasizes the precise placement of the acetabular cup, there's less focus on stem alignment. This study aimed to investigate the impact of the discrepancy between the preoperatively planned femoral neck osteotomy level and the actual osteotomy level during surgery on stem alignment. ⋯ The study examined how differences in planned vs. actual femoral neck osteotomy affect stem alignment in THA using ACTIS stem and Taperloc stem. We found that osteotomy level influenced varus/valgus alignment; mildly affected flexion/extension; and had no effect on anteversion.

Mid-term outcomes of compaction autologous bone grafting in uncemented primary total hip replacement stems.
Fixation and long-term stability of collared, uncemented stems, such as the CORAIL® collared stem, in total hip arthroplasty (THA), depend on a strong cancellous bone sleeve and subsequent osseointegration. This study aimed to investigate bone reaction and mid-term outcomes following compaction autologous bone grafting in uncemented stems in primary THA. ⋯ Autologous compaction bone grafting achieved satisfactory fixation of the uncemented CORAIL® collared stem without requiring distal fixation and mitigated stress shielding. Larger, prospective studies with longer follow-ups are needed to confirm the clinical implications of these mid-term results in primary THA.
