PURPOSE: Patellar tendon shortening may occur following patellofemoral joint replacement (PFJR). We hypothesized that patellar tendon shortening results in unfavourable patient-reported outcomes (PROs). The aim of this study was to determine the effect of patellar tendon shortening following PFJR on PROs. METHODS: In this substudy of a prospective cohort study, a total of 108 patients with isolated patellofemoral osteoarthritis underwent 124 patellofemoral joint replacements...

BACKGROUND: Following a total knee arthroplasty (TKA), restoration of the mechanical axis of the lower limb to a neutral position of 0° ± 3° is generally considered the standard of care. Little is known, however, regarding the impact of realignment defined according to the patient's physiologic anatomy on clinical outcome scores. METHODS: The study included 67 knees with a mean age of 65.9 ± 8.3 years with unilateral osteoarthritis (OA) who underwent a primary unilateral TKA for medial end-stage OA...

INTRODUCTION: The surgical technique used in unicompartmental knee arthroplasty (UKA) is crucial for achieving good short and long term clinical outcomes. The medial mobile bearing UKA has shown excellent clinical outcomes and survivorship. But release of the medial collateral ligament during entering joint is cause of mobile bearing dislocation in short term outcomes and lateral compartment osteoarthritis may occur in the mid to long term outcomes. Removing all osteophytes at the time of UKA is sometime impossible due to their large size and extend to the inferior part of medial tibial plateau and removing them completely my result in release of the MCL...

Hip and knee joint prosthetic implants are common surgical interventions in Switzerland, as well as in other countries. Different care providers are involved in the care process which constitutes a potential risk of inefficiency and communication deficits. A patient can get lost on his cross-sectoral clinical pathway, miss appointments or underestimate the relevance of certain control visits or examinations. To address this, we introduce a concept for a mobile application that guides patients along the cross-sectoral clinical pathway...

Objective Buerger's disease is one of the worst diseases causing peripheral artery occlusions (especially lower extremity) with increased morbidity and mortality. Endovascular treatment of the diseased arteries gains preference over bypass surgery nowadays. Here, we aimed to present the clinical outcomes of 16 consecutive Buerger's disease patients underwent extended endovascular recanalization which is a new technique to restore direct blood flow to at least one foot artery, with the performance of angioplasty for each tibial and foot artery obstructions...

CASE: Congenital aplasia or hypoplasia of the patella by itself is a rare condition; to our knowledge, it has been associated with aplasia of the quadriceps mechanism only 3 times in the literature. We describe a 5-year-old boy who had bilateral fixed flexion deformity of the knee as well as bilateral hypoplasia of the patella and quadriceps mechanism; he never had been able to stand upright and walk. We present the clinical and radiographic features, the surgical details, and the successful outcome after treatment...

INTRODUCTION: Total joint arthroplasty represents the largest expense for a single condition among Medicare beneficiaries. Payment models exist, such as bundled payments, where physicians and hospitals are reimbursed based on providing cost-efficient, high-quality care. There is a need to explicitly define "quality" relevant to hip and knee arthroplasty. Based on prior quality measure research, we hypothesized that less than 20% of developed quality measures are outcome measures...

Few Orthopaedics and Traumatology journals from Latin America and Spain are indexed in major databases; controlled clinical trials published in these journals cannot be exhaustively retrieved using electronic literature searches. We aimed to identify, describe and assess the quality of controlled clinical trials published in Orthopaedics and Traumatology journals from Latin America and Spain through handsearching and evidence mapping methods. We identified controlled clinical trials published in eligible Orthopaedics/Traumatology journals in Spanish until July 2017 by handsearching...
