Anterior knee pain is one of the major short-term complaints after TKA. Since introduction mobile-bearing TKA, numerous studies have attempted to confirm theoretical advantages a TKA over fixed-bearing but most show little or no actual benefits. The concept self-alignment for mobile bearing suggests posterior-stabilized would provide lower incidence anterior compared with We therefore asked whether in fact reduce pain. randomized 103 patients scheduled cemented three-component osteoarthrosis...
Total knee arthroplasty (TKA) is increasingly being performed among working patients suffering from osteoarthritis. Two out of ten do not return to work (RTW) after TKA. Little evidence available about these guide clinicians. Therefore, this study investigates patients' characteristics associated with no RTW. A multicenter retrospective cohort was having undergone a primary TKA during 2005–2010. The following preoperative were assessed: age at surgery, sex, comorbidity, body mass index...
Background and purpose Minimally invasive surgery (MIS) for hip replacement is thought to minimize soft tissue damage. We determined the damage caused by 4 different MIS approaches as compared a conventional lateral transgluteal approach.Methods 5 surgeons each performed total arthroplasty on fresh frozen cadaver hips, using either anterior, anterolateral, 2-incision, posterior, or approach. Postoperatively, hips were dissected muscle color-stained. measured proportional relative...
It is not yet known if unicompartmental knee arthroplasty (UKA) patients are more likely to return work sooner or have improved ability (i.e., workability) than total (TKA) patients. The following questions were addressed: assessed determine: (1) whether they returned UKA compared TKA; (2) had better WORQ function scores TKA patients; and (3) higher workability greater satisfaction regarding A multicenter retrospective cohort study was performed that included at least 2 years after having...
Even in current orthopaedic practice, some cases are still not suitable candidates for hip replacement and fusion remains the only option these highly selected patients. In this retrospective study we describe long-term clinical outcome, quality of life radiological evaluation all adjacent joints a cohort 47 fusions. The main objective our was to show effects fusion. Thirty patients were analysed after an average 18.2 years (range 6.2-30.5 years) with mean SMFA 31.2 9-70). VAS pain fused 1.9...
Recent studies have shown that an increased bleeding tendency can be caused by Selective Serotonin Reuptake Inhibitors (SSRI) use. We aimed to investigate the occurrence and risk of blood transfusion in SSRI users compared non-SSRI a cohort patients admitted for hip-surgery.We conducted retrospective study who underwent planned or emergency hip surgery from 1996 2011 Academic Medical Center Amsterdam. Primary outcome measure was transfusion. Secondary measures were pre- postoperative...
After total knee arthroplasty up to 13% requires revision surgery address loosening. No current diagnostic modalities have a sensitivity or specificity higher than 70-80% detect loosening, leading 20-30% of patients undergoing unnecessary, risky and expensive surgery. A reliable imaging modality is required diagnose This study presents new non-invasive method evaluates its reproducibility reliability in cadaveric study.
Abstract Purpose There is a lack of clear, uniform definition for intraoperatively assessed component loosening knee arthroplasty component, complicating the interpretation and interchangeability results diagnostic studies using an intraoperative observation as reference test. The purpose this study was to establish consensus among specialised revision surgeons regarding determined total or unicondylar components. Methods Utilising Delphi method, international panel highly invited...
To facilitate effective learning, feedback on performance during arthroscopic training is essential. Less attention has been paid to monitoring safe handling of delicate tissues such as meniscus. The goal measure in vitro probing forces menisci and compare them with a theoretical maximum force (TMPF). Menisci samples ten cadavers were mounted platforms up 20 N three directions. Nineteen subjects participated: six novices (experience <60 arthroscopies), intermediates (>60 faculty (>250 year)....
A coronal fracture of the distal femoral condyle is a rare entity and nonunion even more so. The fractures, also known as Hoffa fracture, often involve lateral than medial condyle. Open reduction internal fixation are primary treatment choice. We describe two cases (one one lateral). Although fragment was not attached to any soft tissues in both noted be vital clinically histologically. After operative treatment, consisting debridement, compression with use headless screws, liberal bone...
Purpose Three out of ten patients do not return to work after total knee arthroplasty (TKA). Patient expectations are suggested play a key role. What patients' regarding the ability perform work-related knee-demanding activities 6 months TKA compared their preoperative status? Methods A multi-center cross-sectional study was performed among 292 working listed for TKA. The Work Osteoarthritis or joint-Replacement Questionnaire (WORQ, range 0–100, minimal important difference 13) used assess...
BACKGROUND: Return to work (RTW) is an important outcome in Total Knee Arthroplasty (TKA). At present, 70–80%of TKA patients return within three six months. OBJECTIVE: What are patients’ perspectives regarding beneficial and limiting factors RTW after TKA? METHODS: Focus groups were formed accordance with the Consolidated Criteria for Reporting Qualitative Research (COREQ) checklist. Three major topics explored: 1. was TKA; 2. 3. additional care would benefit RESULTS: Data saturation reached...
Two types of methods are used to assess learning curves: outcome assessment and process assessment. Outcome measures usually dichotomous rare events like complication rates survival or require an extensive follow-up therefore often inadequate monitor individual curves. Time-action analysis (TAA) is a tool objectively determine the level efficiency steps surgical procedure. We currently using TAA number cases needed for surgeons reach proficiency with new innovative hip implant prior...
Background: Total hip arthroplasty (THA) in teenagers is generally avoided. Nevertheless, recent THA procedures a very young patient show improved functional outcomes and implant survival, resulting lower revision rates. This review aims to present an overview of the available literature on provide evidence inform caregivers. Methods: In this systematic review, studies required primary method teenage population. Studies must report at least one following outcome measures: outcomes,...
Abstract Purpose Aseptic loosening often requires major, expensive and invasive revision surgery. Current diagnostic modalities merely show indirect signs of loosening. A recent proof concept study proposed a non‐invasive technique for the quantitative visual assessment implant movement as aid tibial component The primary research question addressed is whether this novel modality can safely effectively diagnosis aseptic Methods This clinical included patients suspected total knee...
Establishing the diagnosis of loosening in total or unicondylar knee arthroplasty remains a challenge with different clinical and radiological signs evaluated study designs high risk bias, where few incomplete criteria are formulated for establishing implant loosening. This aimed at evaluating variability between establish consensus regarding
