Early postoperative activity tracking shows excessive ambulation and poor adherence to recommendations after hallux...

Currently, there is limited information regarding postoperative adherence to surgeon recommendations following hallux valgus surgery. This prospective study aimed to assess early postoperative ambulation and adherence to recommendations using a GPS-enabled wearable device during the postoperative period.

We hypothesized that patients undergoing hallux valgus surgery would exhibit high postoperative activity levels and poor adherence to surgeon recommendations.

A prospective, single-center cohort study was conducted from February to July 2024, including 24 consecutive patients (8 males, 16 females; mean age 53.2 ± 8.3 years) undergoing minimally invasive hallux valgus surgical correction (distal chevron osteotomy, and Akin). A GPS tracker with a 3-axis accelerometer was incorporated into the postoperative dressing, recording step count, movement duration, and location from postoperative Days 1-5. Patients were recommended home rest for the first five postoperative days and to limit ambulation using a postoperative shoe, restricted to essential activities. Adherence to recommendations was assessed based on recorded activity levels and distances traveled. Pain was monitored using a visual analog scale.

Patients exhibited high postoperative ambulation. In total (17/24) 70% engaged in outdoor activity beyond 1 km, and (11/24) 47% walked more than 2000 steps per day. Step count increased significantly from 1797 ± 2397 on Day 1-2937 ± 2140 on Day 5 (p = 0.002). Activity duration also increased from 164 ± 88 min on Day 1-222 ± 95 min on Day 4 (p = 0.002). Pain levels exhibited a significant inverse relationship with activity duration (ρ = -0.26 (p = 0.01)). No postoperative complications were observed at follow-up.

Our study showed high activity levels and poor compliance with postoperative recommendations following hallux valgus surgery during the early postoperative phase. Despite the absence of complications, these findings do not support relaxing postoperative activity restrictions based on this limited cohort. GPS-based wearable tracking might have a potential role in improving postoperative surveillance and refining patient care guidelines.
