Background: At present, updated secondary implant stability data generated by actual versions of resonance frequency analysis (RFA) and mobility measurement (MM) electronic devices of 2 different implant systems with actual manufactured surfaces seem to lack and/or are incomplete.
Material And Methods: Secondary implant stability data based on both RFA and MM measurements were collected and analyzed from 44 formerly treated patients (24 f, 20 m) that received either Ankylos Cellplus (Ø3.5mm) (A) (n=36) or Straumann regular neck SLA tissue level (Ø4.1mm) (S) (n=37) implants in posterior positions of both jawbones (total number= 72). These results were interpretated in view of formerly published data.
Results: Estimated RFA outcomes (mean±SD) for A implants were of 81.23 (±0.65) (LP) - 76.15 (±1.57) (UP) isq; for S implants 76.15 (±1.48) (LP) - 73.88 (±2.34) (UP) isq. Estimated MM outcomes for A implants were (-4.0) (±0.23) (LP) - (-3.2) (±0.33) (UP) ptv; for S implants (-5.15) (±0.39) (LP) - (-4.4) (±0.84) (UP) ptv. According to GEE statistical modelling, implant type and - position seems to influence the outcome variables (<0.05), gender and implant length did not ( >0.05).
Conclusions: Secondary implant stability values, recorded with current RFA and MM devices, of A Cellplus implants are provided for the first time. A difference of 14.7-9.7 isq values was noted for CellPlus versus TPS S implants recorded with a cabled RFA device. This study supports the assumption that RFA outcomes generated with first generation RFA devices are different from those obtained with current RFA devices, meaning that its use in reviews need caution and correction.

Introduction: This retrospective, consecutive, real-world case series assessed the efficacy and safety of third-generation trabecular micro-bypass stent implantation (iStent infinite) with phacoemulsification in patients with mild-to-moderate primary open-angle glaucoma (POAG).
Methods: Patients underwent phacoemulsification combined with implantation of iStent infinite (containing three stents) by a single U.S.

Background: Cardiac rehabilitation programs are planned to reduce the physiological and psychological stress of Cardiovascular Disease, decrease the risk of mortality secondary to CVD, improve cardiovascular function, and help patients to achieve their highest quality of life. However, data on the safety and efficacy of exercise training (ET) in patients with implantable cardioverter defibrillators (ICDs) is sparse. Exercise interventions in those with an ICD have not been extensively studied.

Aim The primary objective of the study was to evaluate the mid-term implant survivability, rate of revisions, and clinical and functional outcomes following patella resurfacing during total knee arthroplasty (TKA) utilizing posterior stabilized (PS) total knee system (TKS). Methods A prospective, single-arm, multi-center, post-marketing surveillance encompassed patients with end-stage primary knee osteoarthritis (OA) or inflammatory arthritis. The time points of the study included baseline, six weeks, six months, one year, and three years post-operatively.

Background: Coronal lower extremity malalignment and improper implant position have been described as risk factors for aseptic tibial loosening following primary total knee arthroplasty (TKA). However, several prior studies have shown no association between alignment and implant loosening. Meanwhile, there is increasing interest in kinematic alignment.

Clinique du sport, Paris, Île-de-France, France.
Background: While there are several scales for measuring patients' outcomes after chronic ankle instability (CAI) surgery, a study comparing the predictive ability of these scores with regard to return to sports (RTS) at the preinjury level is lacking.
Purpose/hypothesis: The purpose of this study was to compare the Ankle Ligament Reconstruction-Return to Sport After Injury (ALR-RSI), American Orthopaedic Foot and Ankle Society (AOFAS), and Karlsson scores in predicting 2-year RTS outcomes after arthroscopic treatment of CAI. It was hypothesized that ALR-RSI would be superior in predicting 2-year RTS outcomes after CAI surgery and that a quantifiable increase in this score would significantly improve RTS outcomes.
