The purpose of this study was to assess total knee arthroplasty (TKA) volume and rates of early complications in morbidly obese patients over the last decade, where the introduction of quality models influencing perioperative care pathways occurred. Patients undergoing TKA between 2011 to 2018 were identified in the American College of Surgeons National Surgical Quality Improvement Program database. Patients were stratified by BMI < 40 kg/m2 and ≥ 40 kg/m2 and evaluated by the number of cases per year. The 30-day rates of any complication, wound complications, readmissions, and reoperation were assessed. Trends in these endpoints over the study period were compared between groups using odds ratios (ORs) and multivariate analyses.Aims
Methods
Recurrent infection following two-stage revision total hip arthroplasty
(THA) for prosthetic joint infection (PJI) is a devastating complication.
The purpose of this study was to report the survival of repeat two-stage
revision hip arthroplasty, describe complications, and identify
risk factors for failure. We retrospectively identified 19 hips (19 patients) that had
undergone repeat two-stage revision THA for infection between 2000
to 2013. There were seven female patients (37%) and the mean age
was 60 years (30 to 85). Survival free from revision was assessed
via Kaplan–Meier analysis. The patients were classified according
to the Musculoskeletal Infection Society (MSIS) system, and risk
factors for failure were identified. Mean follow-up was four years
(2 to 11).Aims
Patients and Methods
Reconstruction of the acetabulum after resection of a periacetabular
malignancy is technically challenging and many different techniques
have been used with varying success. Our aim was to prepare a systematic
review of the literature dealing with these techniques in order
to clarify the management, the rate of complications and the outcomes. A search of PubMed and MEDLINE was conducted for English language
articles published between January 1990 and February 2017 with combinations
of key search terms to identify studies dealing with periacetabular
resection with reconstruction in patients with a malignancy. Studies
in English that reported radiographic or clinical outcomes were
included. Data collected from each study included: the number and
type of reconstructions, the pathological diagnosis of the lesions,
the mean age and follow-up, gender distribution, implant survivorship, complications,
functional outcome, and mortality. The results from individual studies
were combined for the general analysis, and then grouped according
to the type of reconstruction. Aims
Patients and Methods
Advances in polyethylene (PE) in total hip arthroplasty
have led to interest and increased use of highly crosslinked PE
(HXLPE) in total knee arthroplasty (TKA). Biomechanical data suggest
improved wear characteristics for HXLPE inserts over conventional
PE in TKA. Short-term results from registry data and few clinical
trials are promising. Our aim is to present a review of the history
of HXLPEs, the use of HXLPE inserts in TKA, concerns regarding potential mechanical
complications, and a thorough review of the available biomechanical
and clinical data. Cite this article:
1. The case is reported of a woman aged sixty-five with widespread osteosclerosis as a feature of IgA myelomatosis. 2. Improvement was noted after treatment by cyclophosphamide and prednisolone. 3. Only two previously reported cases of myeloma with osteosclerosis of comparable extent have been found, but in forty-seven other cases in the literature some sclerosis has been noted. 4. The finding of sclerotic lesions should not rule out multiple myeloma.
