DECREASED SURGICAL DURATION, LESS COMPLICATIONS, AND FASTER RETURN TO ACTIVITIES ACROSS THE LEARNING CURVE FOR THE ARTHROSCOPIC LATARJET TECHNIQUE.

Objetive: This study aims to analyze the learning curves in performing the arthroscopic Latarjet surgery.

Methods: This was an observational, retrospective, single-center study. All cases of arthroscopic Latarjet performed in this institution from 2016 to 2021 were included. The data analyzed were surgical time (of the chief surgeon alone and the group of surgeons), complications, and time until the return to sports activities. Technical observations about the learning process were also reported.

Results: In total, 50 consecutive cases were included (93% retention of the initial sample identified at the institution). The decrease in surgical time was presented logarithmically and showed a decrease in time both for the individualized analysis of the senior surgeon (r = -0.67, p < 0.001) and for the surgical group (r = -0.476, p < 0.001). Mean operating time (and standard deviation) dropped from 235 minutes (73) in the first 10 cases to 156 minutes (34) for the subsequent cases (p < 0.001). In the first 20 cases, five intercurrences were recorded and three reoperations were performed, whereas subsequent cases presented only one intercurrence requiring surgical intervention (p = 0.032). The median time to return to sport was nine months for the first 20 cases versus six months for subsequent cases (p = 0.001).

Conclusion: The learning curve for the arthroscopic Latarjet procedure showed a progressive decrease in operative time, complications, and time to return to sports activities. This suggests that the surgeon developed the necessary skills and confidence to reach a plateau of expertise to perform the surgical procedure. Level of evidence IV, Observational retrospective.
