Failure of Total Hip Arthroplasty due to Delamination and Wear of Titanium Nitride-coated Titanium Heads: A Case Series.

Introduction: We present the case studies of three patients requiring revision for premature failure of total hip arthroplasty (THA).

Case Report: All patients received titanium nitride (TiN)-coated heads made of titanium alloy TiALV as part of their index total hip replacements. At the time of revision surgery, intraoperative findings included partial or complete delamination of the TiN head coating and wear/deformation of the TiALV heads.

Contributions to Unsupervised Online Misalignment Detection and Bumper Error Compensation for Automotive Radar.

One of the fundamental sensors utilized in the Advanced Driver Assist System (ADAS) is the radar sensor. Automotive-related functions need highly precise detection and range of traffic and surroundings; otherwise, the whole ADAS performance suffers. The radar placement beneath a bumper or a cover, the age or exposure to accidents or vehicle vibration, vehicle integration, and mounting tolerances will impact the angular performance of the radar sensor.

Cementless total hip arthroplasty with anatomic-shaped implants. Does the minimal invasive anterolateral technique influence the stem position or subsidence in contrast to the standard lateral approach?

Introduction: Using cementless stems in total hip arthroplasty (THA) has revealed variable results. The risk for early aseptic loosening has been associated to certain surgical approaches and implant designs. This study determines misalignment of collared/collarless stems and the rate of subsidence using the anterolateral approach (ALA) compared to implantations via the direct lateral approach (DLA).

One-Stage Implant-Retaining Revision for Simultaneous Bilateral Infected Total Knee Arthroplasty: A Report of a Rare Case.

There is little information on the management of simultaneous infected total knee arthroplasties in the same patient. Although general principles of management for periprosthetic joint infection apply, there might be certain aspects worth to be considered. We present a case of a 78-year-old patient, who was referred in preseptic conditions 10 years following bilateral TKA.

Impact of continuous passive motion on rehabilitation following total knee arthroplasty.

Background And Purpose: There is an ongoing controversy in respect of the usage of continuous passive motion (CPM) following total knee arthroplasty (TKA). We analysed the impact of CPM on the early rehabilitation after TKA and the clinical outcome over the time.

Methods: Forty patients were prospectively randomized to postoperative protocols following TKA.
