Randomized Controlled TrialRestoring tibial obliquity for kinematic alignment in total knee arthroplasty: conventional versus patient-specific instrumentation.
In total knee arthroplasty (TKA), tibial obliquity-restoration using kinematic alignment (KA) poses a major difference to conventional mechanical alignment. This study aimed at analysing the accuracy of conventional instrumentation (CI) versus patient-specific instrumentation (PSI) to restore anatomic tibial obliquity measured by the medial proximal tibial angle (MPTA) on conventional X-rays. ⋯ Both conventional and patient-specific instrumentation revealed adequate results with respect to restoring tibial obliquity in kinematically aligned TKA, with conventional instrumentation achieving superior results.

A novel method for evaluating combined component anteversion in total hip arthroplasty on cross-table lateral hip radiographs.
Accurate measurement of combined component anteversion (CA) is important in evaluating the radiographic outcomes following total hip arthroplasty (THA). The aim of the present study was to evaluate the accuracy and reliability of a novel radiographic method in estimating CA in THA. ⋯ Cross-sectional study, Level III.

Does high activity after total and unicompartmental knee arthroplasty increase the risk for aseptic revision?
It has been suggested that high activity might negatively impact implant survival following total and unicompartmental knee arthroplasty (TKA/UKA) and many surgeons advise their patients to only participate in moderate level sport activities. To date, it remains unclear whether such restraints are necessary to assure longevity of the implants. ⋯ The study suggests that participating in sports activity following both UKA and TKA is safe and not a risk factor for revision surgery at a mid-term follow-up. Patients should not be prevented from an active lifestyle following knee replacement.

The use of a standard-length conical tapered stem in hip revision arthroplasty to address Paprosky type I-II femoral defects: a prospective study of 87 patients.
Low-grade femoral defects in revision total hip arthroplasty (rTHA) might be preferably treated with a primary implant. Almost no previous study reported the use of standard-length conical tapered (SLCT) stems in these cases. We analyzed a series of cases using a SLCT stem in rTHA with Paprosky type I-II femoral defects. The purpose of the study was to determine clinical and radiographic outcomes in this series of rTHA. ⋯ The use of a SLCT stem in rTHA with Paprosky type I-II femoral defects demonstrated good survival with low subsidence rates during the first 2 years after surgery. Surgeons should consider the use of this primary prosthesis as a potential treatment during stem revision in cases with limited femoral bone loss.

Forte ceramic-on-delta ceramic cementless total hip arthroplasty: an 8- to 15-year follow-up study.
Forte ceramic head on delta ceramic liner articulation showed satisfactory midterm results without ceramic-related complication. We aimed to investigate the clinical and radiological outcomes of cementless total hip arthroplasty (THA) with forte ceramic head on delta ceramic liner articulation. ⋯ Cementless THA with forte ceramic-on-delta ceramic articulation showed acceptable clinical and radiological results. Serial surveillance of these patients should be performed due to the possibility of cerami- related complications such as squeaking, osteolysis, and ceramic liner fracture.
