Diagnosis of periprosthetic loosening of total hip and knee arthroplasty using 68Gallium-Zoledronate PET/CT.
Periprosthetic loosening is a major complication after total hip and knee arthroplasty. Early and accurate diagnosis is essential to choose the right therapeutic path and to avoid further complications. The aim of the study was to evaluate the diagnostic performance of 68Gallium-Zoledronate ([68Ga]Ga-DOTAZol) PET/CT in detecting periprosthetic loosening in total hip (THA) and total knee arthroplasty (TKA). ⋯ The use of [68Ga]Ga-DOTAZol PET/CT in periprosthetic loosening is a remarkable diagnostic tool and a promising approach. In comparison to established radionuclide tracers, 68Gallium-Zoledronate offers notable advantages due to its availability via 68Ge/68Ga-generators, improving its potential for clinical application.

Femoral head fractures are rare, which limits the experience of individual surgeons with these injuries. This overview examines historical data, injury mechanisms, and classification systems, as well as epidemiological data from larger patient cohorts. ⋯ The literature is often inconsistent, as many studies fail to differentiate between specific fracture types and instead report aggregated results, leading to ambiguous conclusions about the most effective treatment strategies. Thus, this article reviews fracture-type-specific outcomes of both non-operative and operative treatments over the past 25 years and summarizes their clinical implications, with the aim of assisting surgeons in their decision-making processes.

Work productivity after periacetabular osteotomy was affected by preoperative progression of osteoarthritis and heavy workload.
Many patients who have undergone a periacetabular osteotomy (PAO) for developmental dysplasia of the hip (DDH) have had jobs preoperatively. Postoperative return to work and work productivity are important for livelihood security and the social economy. However, there is a lack of evidence on work productivity after PAOs. Therefore, this study investigated the return to work rates and influence of workload, clinical, and radiographic parameters on work productivity after a curved PAO. ⋯ Curved PAOs can improve postoperative work productivity and return to work rates. Preoperative progression of osteoarthritis and heavy workload affect postoperative work productivity.

Accelerometer-based portable navigation system shows no superior accuracy over pelvic alignment guide for acetabular cup placement in total hip arthroplasty in lateral decubitus position.
Total hip arthroplasty (THA) using a portable navigation system (PNS) incurs costs per procedure. However, it does not require a large console. This study aimed to compare the accuracy of acetabular cup placement using a pelvic alignment guide (PAG) attached to the pelvis and an accelerometer-based PNS in THA performed in the lateral decubitus position. ⋯ The accelerometer-based PNS did not demonstrate superior cup alignment accuracy compared to the PAG in THA performed in the lateral decubitus position. This finding informs surgeons that computer-assisted surgery is not necessarily superior to conventional THA using a PAG.
