Comparative StudyPerioperative and short-term outcomes of cemented versus cementless total hip arthroplasty: a retrospective propensity-matched analysis.
Cement fixation for total hip arthroplasty (THA) remains a controversial topic. While cemented stems are associated with lower risk of periprosthetic fractures (PPF), cementless stems may offer superior biological fixation. This study analyzed peri-operative and short-term outcomes of cemented vs. cementless stem fixation in THA. ⋯ III, Therapeutic Study.

Comparative StudySimultaneous bilateral total hip arthroplasty results in smaller Leg length discrepancy than staged bilateral procedures.
The purpose of this study was to compare leg length discrepancies (LLD) between simultaneous and staged bilateral total hip arthroplasty (BTHA). ⋯ Simultaneous BTHA has the potential to provide smaller LLD than staged BTHA because simultaneous surgery enables intraoperative comparison of bilateral leg lengths based on both extra- and intra-articular measurements. This approach may be advantageous for postoperative patient satisfaction.

An increased medial proximal tibial angle of greater than 95 degrees after opening wedge high tibial osteotomy is not associated with deterioration of minimum 10-year clinical outcomes.
The purpose of this study was to assess whether an excessively increased medial proximal tibial angle (MPTA) resulted in the deterioration of long-term clinical outcomes after opening wedge high tibial osteotomy (OWHTO) for patients with knee osteoarthritis (OA). ⋯ Increased MPTA > 95° after OWHTO is not associated with deterioration of minimum 10-year clinical outcomes.

Mid- to long-term clinical and radiological assessment of a short, titanium, porous plasma-splayed flat-tapered cementless femoral stem: An 8- to 12-year follow-up study.
Short cementless stems offer advantages such as bone-stock preservation and minimally invasive insertion. Despite encouraging short- to midterm outcomes, the long-term clinical and radiological implications of short, titanium, and porous plasma-sprayed flat-tapered stems remain unclear. ⋯ The short, titanium, porous, plasma-sprayed, flat-tapered cementless stem exhibited excellent mid- to long-term results in primary total hip arthroplasties with Dorr type A or B femora, comparable with those of other short cementless and standard-length stems. Noteworthy survivorship was observed; however, caution is advised regarding stress-shielding complications, particularly periprosthetic femoral fractures, during extended follow-up.

Long-term results of short stem total hip arthroplasty in patients with osteonecrosis of the femoral head.
Short stem total hip arthroplasty (THA) is an alternative to conventional stem, designed to facilitate minimal-invasive surgery, physiological loading and preserve bone stock. However, there is insufficient evidence of the long-term outcomes in patients with osteonecrosis of the femoral head (ONFH). This study aims to analyze the clinical and radiographic results with a minimum follow-up of 10 years. Furthermore, the survival rate of the short stem was calculated. ⋯ Short stem showed promising long-term clinical outcomes in patients with ONFH. The radiographic results demonstrated physiological proximal load transfer.
