Introduction:
Numerous techniques exist for pediatric medial patellofemoral ligament (MPFL) reconstruction (MPFL-R). Pediatric orthopaedic surgeons and patient families must navigate choices between allograft and autograft, incision type, and surgery cost. While previous research has found similar surgical outcomes among different MPFL-R techniques, minimal data exists on what patients and their families prefer. To engage in shared decision-making (SDM), pediatric orthopaedic surgeons must understand family preferences, including between incision type and cost. We conducted a study utilizing choice-based conjoint (CBC) analysis to explore these preferences.
Methods:
A survey was developed using Sawtooth Software (Lighthouse Studio version 9.2.0) to gather demographic information and preferences on surgical scenarios via CBC analysis. Anonymous participants, recruited via the Prolific crowdsourcing platform, qualified if they were US residents over 18 years of age with children aged 13 to 17. Data analysis involved the Hierarchical Bayes (HB) method to generate utility scores to determine the desirability of attributes.
Results:
The study included 496 participants who prioritized surgical success (average importance 48.8%) followed by co-pay amount (21.5%), incision size (17.4%), and return to sport (12.3%). Participants earning over $200,000 annually prioritized incision size over cost (25.8% vs. 12.1%, P <0.0053). Those with incomes below $50,000 valued recovery time at a lesser extent than other income groups (10.4% than 12.3% overall importance P <0.0003). The sex of the child significantly influenced preferences: incision size was more important to parents of girls (21.1%) than boys (14.0%, P <.0001). The importance of surgery success and recovery time also differed by sex, being higher for boys (50.4%, 13.1%) than girls (47.0%, 11.7%; P =0.025, 0.026, respectively).
Conclusions:
This CBC analysis suggests parents of adolescent patients undergoing MPFL-R most value surgical success (avoiding revision surgery), followed by copay, incision size, and time to return to sport. Of note, parent income level and sex of the child significantly influenced parental preferences. We hope this information will assist orthopaedic surgeons in SDM in MPFL-R surgery.
Level Of Evidence:
Level III.
