The purpose of this study was to compare the all-polyethylene tibial component with the modular metal-backed component in primary total knee arthroplasty. A retrospective review of 1064 patients recorded clinical failure, as determined by need for revision surgery, range of motion, and impending radiographic loosening, as evaluated by the presence of radiolucent lines. Mean follow-up was 1.2 and 3 years, respectively. Survival in the all-polyethylene group was 100%, with 95.5% (95% CI: 85.8-98.6) survival i...
The geriatric population represents a rapidly growing segment of society with prolonged life expectancies and more active lifestyles. Many of these patients have already undergone primary total hip arthroplasty (THA) and are presenting with aseptic loosening, polyethylene wear, osteolysis, or periprosthetic fractures. Therefore, the demand for hip revision procedures is expected to grow. Currently, there are many modular implant options available for use in complicated revision THA. Early results of modular...
Osteonecrosis of the hip is the underlying etiology for 3% to 12% of total hip arthroplasties (THAs). Compared with patients who undergo THA because of osteoarthritis, those who do so because of osteonecrosis typically are younger, have a greater number of underlying diagnoses, and have inferior clinical outcomes and implant survivorship. The purpose of this study was to compare the long-term implant survivorship (median follow-up, 10 years), functional outcomes, and radiographic results of contemporary THA...
The primary objective was to evaluate the correlation between 5-year radiographic structural disease progression and early clinical remission in recent-onset rheumatoid arthritis (RA). The secondary objective was to assess the correlation between erosion development in joints free of damage at baseline and early clinical remission.
The risk of early complications is high after monoblock acetabular metal-on-metal (MoM) THA revisions. However, there is a paucity of evidence regarding clinical complications after isolated head-liner exchange of modular MoM THA.
The objectives of this study were to compare (i.) esthetic, (ii.) clinical (iii.) radiographic and (iv.) patient centered outcomes following immediate (Type 1) and early implant placement (Type 2).
To describe the radiographic and symptomatic course in subjects with hip or knee complaints suspected of early osteoarthritis (OA).
A variety of highly porous materials have been used to obtain biological acetabular fixation after total hip arthroplasty (THA). Due to their improved surface-coated properties, new highly porous titanium metal implants have shown potential to promote prosthesis osseointegration. Therefore, the purpose of this multicenter study was to evaluate: 1) overall acetabular cup survivorship; 2) postoperative complications; and 3) radiographic signs of loosening and radiolucencies in patients who received a new high...
Hooded acetabular liners and head sizes ≥ 32 mm have both shown to have a beneficial effect on the revision rate for dislocation in THA. Experience with noncrosslinked polyethylene (nonXLPE) raised concerns regarding the risk of impingement damage, loosening, and osteolysis with hooded liners; however, the evidence for this in crosslinked polyethylene (XLPE) is inconclusive. The interaction between different femoral head sizes and hooded liners is not well understood, and it is unclear whether hooded XLPE...
Adverse reactions to metal debris after total hip arthroplasty are an increasing concern. Metal debris is released from the metal-on-metal articulation itself as well as from the head-neck taper. There is also a risk of corrosion at the neck-stem junction. Some stems were recalled because of high revision rates as a result of metal debris from the modular junction. We conducted a retrospective analysis of the 3-year to 8-year clinical and radiographic outcomes of a consecutive cohort of patients who underwe...
Optimal cancer survivorship care needs its comprehensive guidelines. We aimed to identify English and Japanese guidelines that include cancer survivorship in their title, the issues highlighted in such guidelines, and any existing oncology practice guidelines in Japan that address these issues.
All-polyethylene tibial (APT) implants were incorporated into the initial design of the first total knee arthroplasty (TKA) systems. Since then, a dynamic shift has taken place and metal-backed tibial (MBT) implants have become the gold standard in TKA. This has mostly been due to the theoretical advantages of intraoperative flexibility and improved biomechanics in addition to the heavy influence of device manufacturers. MBT implant comes not only with a higher cost but also with potential for complications...
Polyethylene (PE) liner and femoral head exchange is commonly used to treat periprosthetic osteolysis associated with PE wear after total hip arthroplasty (THA). The purpose of our study was to determine long-term implant survivorship, risk factors for mechanical failure, clinical outcomes, and complications following PE liner and head exchange.
Robotic-assisted TKA was introduced to enhance the precision of bone preparation and component alignment with the goal of improving the clinical results and survivorship of TKA. Although numerous reports suggest that bone preparation and knee component alignment may be improved using robotic assistance, no long-term randomized trials of robotic-assisted TKA have shown whether this results in improved clinical function or survivorship of the TKA.
A quality review process was implemented to determine compliance with the requirement from the Commission on Cancer to use the American Society of Clinical Oncology (ASCO) template as the minimum data set for Treatment Summary and Survivorship Care Plans (TS/SCP) provided to cancer survivors.
To characterize the relationship between radiographic and clinical characteristics of patients with temporomandibular joint (TMJ) osseous changes.
Computed tomography (CT) is more accurate than plain pelvic radiography (PXR) for evaluating acetabular fracture reduction. As yet unknown is whether CT-based assessment is more predictive for clinical outcome. We determined the independent association between reduction quality according to both methods and native hip survivorship following acetabular fracture fixation.
Aseptic loosening and wear is second to only infection as the most common cause of arthroplasty failure. Degeneration of the polyethylene and metal arthroplasty components can lead to metallosis, which can cause a combination of direct cytotoxic effects and an inflammatory response within the synovial and periarticular tissues. This can result in bone resorption and secondary arthroplasty component loosening as well as a metal containing joint effusion and metal-induced synovitis. Little literature exists a...
Valve-sparing aortic root replacement (VSARR) is an increasingly popular alternative to traditional aortic root replacement for aortic root aneurysm disease with a normal aortic valve. We evaluated the early and midterm outcomes of VSARR-reimplantation technique (VSARR-RT) done at a single institution over a decade.
To unravel the hierarchy of cellular/molecular pathways in the disease tissue of early, treatment-naïve rheumatoid arthritis (RA) patients and determine their relationship with clinical phenotypes and treatment response/outcomes longitudinally.
Early treatment intensification for type 2 diabetes mellitus (T2DM) is often required to achieve glycaemic control and avoid longer-term complications. We assessed associations between early versus later dapagliflozin initiation with changes in glucose control, weight, and blood pressure using UK Clinical Practice Research Datalink (CPRD) data.
Early postoperative reactions occur following lateral sinus floor elevation (LSFE). This article radiographically describes, quantifies, and measures these early postoperative changes inside grafted maxillary sinus area.
Patients with blunt chest trauma with multiple rib fractures (RF) may require tracheostomy. The goal was to compare early (≤7 d) versus late (>7 d) tracheostomy patients and to analyze clinical outcomes, to determine which timing is more beneficial.
A main drawback of bone block graft surgery is the resorption occurring in early stages of healing. To our knowledge, there are no studies comparing outcomes of freeze-dried bone allograft (FDBA) blocks with different architecture.
Patients are commonly advised to wear a sling for 4 to 6 weeks after rotator cuff repair despite negative effects of early immobilization and benefits of motion rehabilitation. The aim of this study was to compare clinical and radiographic outcomes up to 6 months following rotator cuff repair with and without postoperative sling immobilization.
