Measurement properties of the HOOS-PS in revision total hip arthroplasty: a validation study on validity, interpretability, and responsiveness in 136 revision hip arthroplasty patients.

Background And Purpose: To determine whether the Hip disability and Osteoarthritis Outcome Score-Physical function Short-form (HOOS-PS) is able to appropriately evaluate physical function in revision hip arthroplasty patients, this study assesses psychometric properties of the Dutch HOOS-PS in this patient population.

Patients And Methods: We assessed psychometric properties of the HOOS-PS following the Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) criteria. Content validity, including comprehensibility, comprehensiveness, and relevance of the items, was assessed using cognitive debriefing interviews in hip revision patients (n = 8) and orthopedic surgeons specialized in revision surgery (n = 7).

A modified Gritti-Stokes amputation technique as a solution for recurring aseptic loosening of a knee arthroplasty: A single-patient case study.

Case Description: A 56-year-old man with persistent knee pain and poor physical functioning due to recurring loosening of a (revised) total knee arthroplasty, was treated with a modified Gritti-Stokes amputation.

Objectives: to describe the modified Gritti-Stokes amputation technique as an ultimate therapy for failed total knee arthroplasty and to assess the functional outcome for one patient 1 year post-surgery.

Study Design: a single patient case study.

First results of a uniform regional treatment protocol and registration for acute prosthetic join infection in the South-East of the Netherlands.

Prosthetic joint infection (PJI) is a relatively uncommon (average incidence 0.5-2%) but devastating complication, with significant morbidity and leading to tremendously increased health care costs. In 2013, delegates from nine hospitals covering a large region in the South-East Netherlands composed one combined treatment protocol for acute PJI of total hip and knee arthroplasty (THA and TKA).

Optimization of the empirical antibiotic choice during the treatment of acute prosthetic joint infections: a retrospective analysis of 91 patients.

Background and purpose - The preferred treatment of an acute prosthetic joint infection (PJI) is debridement, antibiotics, irrigation and retention of the prosthesis (DAIR). The antibiotic treatment consists of an empirical and targeted phase. In the empirical phase, intravenous antibiotics are started after surgery before micro-organisms are determined in microbiological cultures.

The long-term prognosis of Legg-Calvé-Perthes disease: a historical prospective study with a median follow-up of forty one years.

Purpose: The purpose of this study is predicting the clinical and radiological long-term outcome and identifying prognostic factors of Legg-Calvé-Perthes disease (LCPD) in Catterall 2 and 3 hips.

Methods: Sixty hips (59 patients) were diagnosed with LCPD between 1959 to 1974 and were followed prospectively. Forty-two of these 60 hips were classified as Catterall 2 or 3.

Reason for revision TKA predicts clinical outcome: prospective evaluation of 150 consecutive patients with 2-years followup.

Background: There is limited knowledge regarding the relationship between the reason for revising a TKA and the clinical outcome in terms of satisfaction, pain, and function with time.

Questions/purposes: In a cohort of patients receiving a fully revised TKA, we hypothesized (1) outcomes would differ according to reason for revision at 2 years, (2) outcomes would improve gradually during those 2 years, (3) rates of complications differ depending on the reason for revision, and (4) patients with complications have lower scores.

Methods: We studied a prospective cohort of 150 patients receiving a fully revised TKA using a single implant system in two high-volume centers at 24 months of followup.
