Revision Total Knee Arthroplasty for Catastrophic Tibial Post Failure: Rare Complication of Total Knee Replacement.

Tibial post failure is a rare but serious complication of posterior-stabilized total knee arthroplasty that requires revision surgery. Although tibial post fracture has previously been reported, this case involves an implant with a design feature that may predispose patients to the complication. The fracture also occurred later than observed in most other reports.

Improvise, Adapt & Overcome: Successful Surgery-Sparing Prosthetic Hip Infection Antibiotic Suppression During COVID-19 Crisis.

Case: A 79-year-old active male presented during the first COVID-19 pandemic surgery moratorium with late Staphylococcus lugdunensis periprosthetic total hip arthroplasty infection. Due to the unprecedented circumstances, novel treatment of IV and oral antibiotic suppression was trialed without preceding surgical intervention. At latest follow-up, the patient has two-year revision-free survival with normalization of inflammatory markers and MRI findings, and resolution of clinical symptoms.

Role of corrosion in taper failure and head disassociation in total hip arthroplasty of a single design.

Modular junctions have been associated with corrosion in total hip arthroplasty. In a small number of cases, disassociation of the femoral head from the stem following gross wear of the taper has been reported. The purpose of this study was to investigate the role of corrosion in the development of mechanical changes leading to disassociation.

Minimum Five-Year Outcomes with Porous Tantalum Acetabular Cup and Augment Construct in Complex Revision Total Hip Arthroplasty.

Background: The use of a trabecular metal revision shell with metal augmentation to fill segmental or irregular defects during complex revision hip arthroplasty has been shown to provide good short-term results in prior published series. Longer-term results of the several cup-augment constructs used clinically are not known. The objective of this study was to report, with minimum 5-year radiographic and clinical follow-up, the outcome of these various constructs in revision total hip arthroplasty.

Modifiable Risk Factors in Total Joint Arthroplasty: A Pilot Study.

Unlabelled: Strong evidence exists to suggest that morbid obesity, smoking, and poorly controlled diabetes mellitus are associated with poorer outcomes after total joint arthroplasty. To our knowledge, no study has reported the effect of the implementation of a risk reduction strategy. Risk factors, based on published data, were defined as Body Mass Index (BMI)>40, Hemoglobin A1c (HbA1c) >8.

Total joint arthroplasty in patients with chronic infectious liver disease.

The opportunity for total joint arthroplasty (TJA) in patients with chronic infectious liver disease is rapidly expanding. This is the product of both superior survival of chronic hepatitis patients, evolving implant technologies, and improvement of techniques in TJA. Unfortunately, treating this group of patients is not without significant challenges that can stem from both intrahepatic and extrahepatic clinical manifestations.
