Background: Total hip and knee arthroplasty (THA and TKA) are two of the most common joint arthroplasties performed in the United States, with the prevalence of these procedures anticipated to continue increasing with the aging population. Therefore, medical education programs must expose students to the pathology, mechanisms of surgical intervention, and variance in implant materials for THA and TKA. One of the purposes of the WMed Skeletal Teaching and Research (STaR) Series is to target this educational goal, however, considering whether the collection is representative of the surrounding population is imperative when training medical providers to care for local communities. As few formal skeletal collections exist within the United States, research pertaining to representation of orthopedic surgeries is arguably nonexistent. The WMed STaR Series aims to target this gap in research, comparing representation of THA and TKA from the series to community statistics.

Methods: Donors from the WMed STaR Series were thoroughly evaluated for the presence of THAs and TKAs, as well as associated musculoskeletal pathology. The type and material of implant, laterality of intervention, donor medical history, and donor demographics were documented. Preliminary data collected from the series was evaluated in comparison to national statistics, and will plan to be compared to analogous data from orthopedic patients seen at the WMed Health clinic.

Results: The American College of Rheumatology cites about 1.2 million TKA and THA procedures in the U.S. annually with approximately 36.3% being THA and 63.7% being TKA. Upon evaluation of the STaR series, there were six THA (83% with a metal femoral head and a polymer socket, and the remaining 17% with a ceramic femoral head and a polymer socket) and seven TKA (all with metal tibial and femoral components and plastic spacers). This results in a relative frequency of 46.2% THA and 53.8% TKA in the WMed STaR Series, showing that while WMed has a similar proportion of THA and TKA to the national statistic, the STaR Series shows slightly higher prevalence of THA.

Conclusion: The development of the WMed STaR Series will provide educators with a reference for orthopedic implants available for medical education, and will offer a unique perspective for further understanding of musculoskeletal pathology and mechanism for surgical intervention. Medical education resources that reflect the surrounding populations, such as the WMed STaR series, are imperative to prepare medical trainees to deliver comprehensive care to their communities.
