Comparative StudyEpiphyseal fixation in revision total knee arthroplasty: a comparison between trabecular metal and titanium augments.
The purpose of this retrospective study was to compare the medium-term clinical and radiographic outcomes of two series of patients treated for revision TKA: one implanted with trabecular metal (TM) augments and one implanted with classic titanium augments. ⋯ The use of TM augments directly screwed to the epiphysis of the femur and the tibia reduced the incidence of RLL compared to standard titanium augments during revision TKA with promising medium-term results.

Validation of the hip disability osteoarthritis outcome Score-12 shortform in a German cohort.
To consider the inherent respondent burden of PROMs, the HOOS-12 as a shortform of the well-established HOOS questionnaire has been published. While the HOOS-12 has been validated in an initial study, further evaluation in other, non-English speaking cohorts is necessary. We therefore aimed to evaluate responsiveness, convergent construct validity, internal consistency, and floor and ceiling effects of the HOOS-12 in a cross-sectoral german cohort. ⋯ The HOOS-12 showed good convergent construct validity and is responsive to changes in pain, function, QoL and hip impact between preoperatively and 1 year postoperatively. A substantial ceiling effect for all subscales at 1 year postoperatively limits the ability to capture variance across particularly well performing patients.

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.

Can we identify abnormal pelvic tilt using pre-THA anteroposterior pelvic radiographs?
Patients with increased pelvic tilt (PT) are at risk for instability following total hip arthroplasty (THA). Identification of increased PT using anteroposterior (AP) pelvic radiographs could avoid additional spinopelvic radiographs. This study aimed to (1) describe which AP pelvic parameters most accurately estimate sagittal PT, and (2) determine thresholds for these parameters that can identify patients with increased PT. ⋯ Level II, diagnostic study.

Three-dimensional acetabular reorientation during periacetabular osteotomy: an intraoperative navigation method using an external fixator for periacetabular osteotomy.
Bernese periacetabular osteotomy (PAO) is an effective procedure for treating acetabular dysplasia. However, limited visual control of the acetabular position during surgery may result in under- or overcorrection or changes in acetabular version resulting in residual dysplasia or femoroacetabular impingement. Thus, we wanted to develop a simple and straightforward navigation method that provides information about acetabular correction in all three planes during surgery. ⋯ Three-dimensional control of the acetabular orientation during periacetabular osteotomy is important to avoid over- and undercorrection. Using a fixateur externe as an analog navigation method this three-dimensional control can be implemented intraoperatively for PAOs.
