Abstract
The John N. Insall Knee Society Traveling Fellowship selects four international arthroplasty
or sports fellowship-trained orthopaedic surgeons to spend 1 month traveling to various
Knee Society members' joint replacement and knee surgery centers in North America.
The fellowship aims to foster research and education and shares ideas among fellows
and Knee Society members. The role of such traveling fellowships on surgeon preferences
has yet to be investigated. A 59-question survey encompassing patient selection, preoperative
planning, intraoperative techniques, and postoperative protocols was completed by
the four 2018 Insall Traveling Fellows before and immediately after the completion
of traveling fellowship to assess anticipated practice changes (e.g., initial excitement)
related to their participation in a traveling fellowship. The same survey was completed
4 years after the completion of the traveling fellowship to assess the implementation
of the anticipated practice changes. Survey questions were divided into two groups
based on levels of evidence in the literature. Immediately after fellowship, there
was a median of 6.5 (range: 3–12) anticipated changes in consensus topics and a median
of 14.5 (range: 5–17) anticipated changes in controversial topics. There was no statistical
difference in the excitement to change consensus or controversial topics (p = 0.921). Four years after completing a traveling fellowship, a median of 2.5 (range:
0–3) consensus topics and 4 (range: 2–6) controversial topics were implemented. There
was no statistical difference in the implementation of consensus or controversial
topics (p = 0.709). There was a statistically significant decline in the implementation of
changes in consensus and controversial preferences compared with the initial level
of excitement (p = 0.038 and 0.031, respectively). After the John N. Insall Knee Society Traveling
Fellowship, there is excitement for practice change in consensus and controversial
topics related to total knee arthroplasty. However, few practice changes that had
initial excitement were implemented after 4-year follow-up. Ultimately, the effects
of time, practice inertia, and institutional friction overcome most of the anticipated
changes induced by a traveling fellowship.
