Introduction: No significant regression has been reported in revision total hip arthroplasty (THA) rates despite substantial progress in implant technologies and surgical techniques. It is critical to investigate how patient demographics, THA indications, surgical techniques, types of implants, and other factors influence the frequency of early and late revision surgery. The main purpose of the present study was to evaluate the clinical characteristics and 10-year survival rates of revision hip arthroplasties among revision time groups.
Material And Methods: The clinical data of 396 patients who underwent revision hip arthroplasty between 2005 and 2011 were evaluated in this multi-centre study. Patients were assigned to one of four revision time groups based on the interval between the index hip arthroplasty and the revision surgery (< 2, 2-5, 5-10, and > 10 years).
Results: There were significant differences among revision time groups in terms of aetiology for primary hip arthroplasty, indications for revision hip arthroplasty, and types of revision procedures. Patients with hip dysplasia more frequently received revision hip arthroplasty within 2 years in contrast to those with osteoarthritis. Revision hip arthroplasties due to periprosthetic infection and instability were conducted earlier compared to aseptic loosening. The overall 10-year survival rate of revision hip arthroplasty was 83.2%, and it was highest for the very early revisions (< 2 years).
Conclusions: According to our results, early revision hip arthroplasty was found to be mostly dependent on surgery-related factors rather than demographic factors. On the other hand, we observed that survival rates of very early revision hip arthroplasties are higher than late revision hip arthroplasties.

Patellar Instability After Total Knee Arthroplasty.
J Knee Surg

Lenox Hill Hospital Department of Orthopedic Surgery, Northwell Health, New York, United States.
Patellar instability following total knee arthroplasty (TKA) is a rare, yet serious complication, potentially requiring revision surgery or resulting in chronic dysfunction. When encountered, it is paramount to understand the etiologies, diagnostic approaches, treatment options, and outcomes of the selected treatment. The most common cause of patella instability is improper positioning of components, leading to lateral maltracking of the patella.

Purpose: Studies evaluating the long-term survival rate, patient satisfaction, and conversion to total hip arthroplasty (THA) are limited. The aim of this study was to evaluate satisfaction and hip survival at a minimum 10-year follow-up in patients following hip arthroscopy for femoroacetabular impingement syndrome (FAIS).
Methods: A total of 164 patients underwent hip arthroscopy for FAIS between 2007 and 2012; of these, 76 (49 men and 27 women; mean age, 40.
The 'Japanese paradox' of total hip arthroplasty: where are we going?
Expert Rev Med Devices
January 2025
Department of Orthopaedic Surgery, Kansai Medical University, Hirakata, Osaka, Japan.
Introduction: There is a worldwide trend toward 'revisiting' cemented total hip arthroplasty (THA). In Japan, however, cemented THAs accounts for 11%, and the percentage of cemented hemiarthroplasty is estimated to be less than 10%. This review was designed to reconsider the option of cemented THA and to encourage policy changes in Japan to support the best possible care for patients.

It is important to provide an overview of the current management of periprosthetic fractures, including techniques for osteosynthesis and revision total hip and knee arthroplasty, as well as special considerations for periprosthetic acetabular fractures, periprosthetic tibial fractures, and interprosthetic femur fractures. In addition, the guiding principles for the management of potential subsequent complications including infection, nonunion, and instability are discussed.

Article Synopsis
- The Johnson and Johnson faulty hip implant case affected nearly 93,000 patients globally, prompting immediate action like revision surgeries and reimbursements in several countries, while India faced a significant delay.
- In India, defective implants continued to be sold after a global recall, resulting in 4,700 surgeries before the government intervened.
- The paper analyzes India's weak medical device regulations, pointing out failures in monitoring, oversight, and patient tracing, ultimately calling for urgent reforms to enhance patient safety.
