Arthroscopy Within Three Months Prior to Unicompartmental Knee Arthroplasty Is Associated With an Increased Rate of Periprosthetic Joint Infection.

Background: Arthroscopy remains a commonly performed procedure in patients who have meniscal or other osteochondral pathology prior to ultimately being indicated for unicompartmental knee arthroplasty (UKA). The purpose of this study was to examine the timing of knee arthroscopy prior to UKA and its association with 2-year periprosthetic joint infection (PJI) rates and medical and surgical complications.

Methods: Patients undergoing UKA who had history of ipsilateral arthroscopy within 2 years prior to the UKA were identified in a national insurance database.

Financial Conflicts of Interest and Industry Funding are Associated With Conclusions Favorable to New Technologies: A Review of Published Economic Analyses in Hip and Knee Arthroplasty.

Background: New technologies in hip and knee arthroplasty are commonly evaluated using cost-effectiveness analyses and similar economic assessments. There is a wide variation in the methodology of these studies, introducing the potential for bias. The purpose of this study was to evaluate associations between potential financial conflicts of interest (COI) and the outcomes of economic analyses.

The Impact of Robotic-Assisted Total Knee Arthroplasty on Resident Training.

Background: As robotic-assisted total knee replacement (rTKA) continues to gain popularity, the impact of this technology on resident education remains unknown. The purpose of this study was to describe trainee experience and perceptions of rTKA and its effect on surgical training.

Methods: Two hundred and twenty two senior orthopaedic residents attending a national board review course completed a 17-question survey regarding their experience and perceptions regarding rTKA.

Are We Training Surgeons to Cement a Femoral Component in Hip Arthroplasty? The Trainees' Perspective.

Background: The importance of surgical technique is widely recognized when cementing a femoral component in hip arthroplasty. Concern exists that surgeon trainees in the United States are not being adequately trained in cement technique. The purpose of this study is to describe recent trainees' perceived experience with their training in this skill.

Clinical Outcomes After Stage-One Antibiotic Coated Molded Hip Spacer.

Background: Two-stage exchange remains the gold standard for managing periprosthetic joint infection (PJI). We evaluated the outcomes of patients treated with a specific molded articulating antibiotic hip spacer for PJI at a tertiary referral center.

Methods: An institutional database was retrospectively queried for patients who underwent implantation of spacer between 2009-2019.

Fracture of a 40-mm BIOLOX Delta Femoral Head.

Ceramic bearing surfaces have gained popularity in total hip arthroplasty as a result of the favorable mechanical properties and low wear rates. Despite the recognition as an attractive articulation, problems such as ceramic head fracture persist. Smaller heads and higher body mass indices are touted as risk factors for ceramic head fracture and are often associated with antecedent trauma.
