Evaluating the Role of Supervised Early Operative Exposure in Improving Surgical Confidence and Patient Outcomes in Junior Orthopedic Residents

Summary

This protocol presents structured, supervised early operative exposure model for junior orthopedic residents. It outlines standardized resident allocation, direct faculty supervision, and stepwise progression of operative responsibilities. The protocol also includes monitoring of operative performance and outcomes to support safe skill development, competency-based surgical training, and improved technical proficiency during early residency.

Abstract

This prospective multicenter controlled cohort study evaluated whether structured supervised early operative exposure improves educational and clinical outcomes among junior Orthopedic residents. The goal of this protocol is to describe a structured, competency-based approach for implementing supervised early operative exposure in orthopedic residency training and evaluating its educational and clinical impact. Ninety-six first and second-year residents across three tertiary teaching hospitals were allocated to early exposure or traditional training and followed for 12 months. Residents receiving early supervised exposure demonstratedprocedures andincrease in surgical confidence (mean change 2.4 points; 95% CI 1.9–2.9; p < 0.001), reduced operative duration by approximately 20% in common procedures, and maintained low complication rates within accepted clinical benchmarks. Patient satisfaction and functional recovery outcomes remained high and improved in parallel with resident development. Surgical confidence showed a strong positive correlation with supervisor-rated technical skill (r = 0.81). These findings indicate that competency-based supervised early operative participation enhances resident performance and patient outcomes without compromising safety, supporting its integration into Orthopedic residency training.

Introduction

The acquisition of surgical competence and confidence among junior Orthopedic residents is a critical determinant of both trainee progression and patient outcomes¹. Early supervised operative participation has been associated with accelerated skill development, improved clinical judgment, and greater preparedness for independent practice^2,3 By enabling residents to translate theoretical knowledge into real operative performance under expert guidance, structured supervision offers a balanced pathway between progressive autonomy and patient safety^4,

Protocol

Ethics statement
This study protocol was approved by the Institutional Review Board (IRB) of Xuanwu Hospital Capital Medical University (Approval ID: [2018] 083) and was conducted in accordance with the ethical standards of the Helsinki Declaration. Informed consent was obtained from all participating residents and patients prior to data collection.

1. Study design and setting

1. Implement a prospective randomized controlled cohort multi-center study over 12 consecutive months (January–December 2025).
2. Select three tertiary teaching hospitals in China based on: Annual Orthopedi....

Results

Participant characteristics and baseline comparability
A total of 112 junior orthopedic residents were screened for eligibility. Of these, 16 residents were excluded (8 did not meet inclusion criteria and 8 declined participation). The remaining 96 residents were randomized into two groups: 48 residents in the early operative exposure cohort and 48 residents in the traditional training cohort. During follow-up, 3 residents from the early exposure cohort and 4 from the traditional cohort were lost to .......

Discussion

This multi-center investigation found that structured, supervised early operative exposure for junior orthopedic residents was associated with higher surgical confidence, faster technical skill acquisition, and improved patient outcomes without compromising procedural safety. Critical to the success of this protocol is the consistent application of structured supervision, clearly defined autonomy thresholds, and standardized inter-institutional calibration procedures. Variability in supervision intensity, case allocation.......
