Learning curve associated with minimally invasive surgery for hallux valgus: A systematic review.

Background: The purpose of this systematic review is to examine the learning curve associated with minimally invasive surgery (MIS) for the treatment of hallux valgus (HV).

Methods: A systematic review was performed using PubMed, ScienceDirect, Web of Science, CINAHL and MEDLINE databases from database inception to February 16th, 2023. Inclusion criteria was articles with level of evidence I-III, any outcomes associated with learning curve, minimally invasive surgery, and diagnosis of hallux valgus' in adult patients.

Results: Six articles out of 165 articles meet inclusion criteria. For all six articles, 368 total patients (422 total feet) were included in the study with an average age of 55.69 years. Three studies reported the number of surgeries needed to reach the plateau phase of the learning curve of MIS for HV, with a frequency weighted mean of 35.5 surgeries (range 27 - 40). In the selected articles, significant results were found for increased operating room (OR) time and fluoroscopy shots in the learning phase. There was no significant increase in complications in the learning phase. There was no significant decrease in patient outcomes, or the quality of correction performed during the learning phase.

Conclusion: An average of 35.5 surgeries (range 27 - 40) are needed to reach the plateau phase for MIS for HV. The learning phase of the learning curve of MIS for HV has a significant increase in OR time and fluoroscopy usage. However, the learning phase of the learning curve of MIS for HV is not associated with decreased outcomes or higher complication rates based on the small sample size in this study.

Level Of Evidence: Level III, Systematic Review.
