The purpose of our study was to investigate the clinical efficacy of a three-dimensional printed integrated acetabular prosthesis (IAP) in total hip arthroplasty (THA) for developmental dysplasia of the hip (DDH) with different Crowe types.

Most of the focus regarding total knee arthroplasty (TKA) implant positioning and alignment has been centered on the coronal plane. Posterior condylar offset (PCO) and tibial slope (TS) are sagittal parameters that are measured on radiographs, managed intraoperatively, and are crucial to a stable TKA. We sought to compare whether robotic-assisted TKA (raTKA) versus manual TKA (mTKA) are different with regard to achieving a surgeon’s preoperative sagittal targets.

Periprosthetic femoral fractures (PPFs) following total hip arthroplasty (THA) are challenging complications, and as THA is increasingly performed in younger, more active populations, the incidence of PPFs is expected to rise. Treatment often requires tapered titanium stems to provide axial and rotational stability, and cerclage fixation is commonly used. Traditional metallic cerclage cables are effective, but carry risks such as fretting, corrosion, and intraoperative injury. Polymer-based cerclage cables have emerged as an alternative, though biomechanical data comparing them to metallic cables is limited.

Pelvic bone loss in the setting of total hip arthroplasty (THA) creates a challenge for reconstructing the acetabulum during revision THA. The complexity of managing acetabular bone loss lies in its highly variable presentation, ranging from minor osteolytic defects to extensive segmental and cavitary deficiencies. This article will highlight treatment options for complex pelvic defects (Paprosky 3A/3B) and frequently associated pathology, such as instability and infection.

This study aimed to analyze the clinical, functional, and radiographic outcomes of patients who had Crowe type 3 or 4 developmental dysplasia of the hip (DDH) undergoing cementless total hip arthroplasty (THA) using a conical fluted femoral stem in combination with a transverse subtrochanteric femoral shortening osteotomy without internal fixation.

Modular fluted tapered (MFT) stems have become popular in revision total hip arthroplasty (THA); therefore, it is imperative to understand the clinical outcomes of these stems, particularly in elderly patients, a population that has seldom been studied. This study aimed to report the cumulative incidence of reoperation among elderly patients who underwent aseptic revision THA with MFT stems.

Acute pelvic discontinuity (PD) is a rare, yet challenging complication following total hip arthroplasty (THA). Although several techniques, such as plating of the posterior column and spanning of the discontinuity with a cup cage, have been described for the management of acute PD, few studies have determined the survivorship of acetabular constructs in this setting. The purpose of this study was to determine the outcomes of acetabular fixation of the posterior column in patients who had acute PD following THA.
