BACKGROUND: Proximal fibular osteotomy (PFO) is a surgical treatment for medial knee osteoarthritis (MKOA). This study aimed to evaluate the safety and efficacy of a novel instrument, the Threading Saw Pliers, compared to conventional techniques in performing PFO.
METHODS: Between February 2021 and February 2023, 80 patients undergoing PFO for MKOA were allocated into two groups based on the chronological introduction of the tool: the Modified group (using Threading Saw Pliers, n = 40) and the Conventional group (n = 40). Operating time, intraoperative blood loss, perioperative complications, Visual Analogue Scale (VAS) score, Knee Society Score (KSS), and Hospital for Special Surgery Knee Score (HSS) were assessed. The follow-up span over a time line of at least 12 months.
RESULTS: Baseline characteristics were similar between the two groups. The Modified group demonstrated a significantly shorter mean operating time (25.14 ± 8.11 vs. 55.33 ± 6.90 min, P < 0.001) and reduced mean blood loss (20.11 ± 30.29 vs. 101.19 ± 29.33 ml, P < 0.001). The overall perioperative complication rate was markedly lower in the Modified group (2.5% vs. 27.5%, P = 0.007). While VAS, KSS, and HSS scores showed significant improvement from preoperative values within each group at 6 and 12 months postoperatively (P < 0.05), there were no significant differences in these clinical outcomes between the two groups at either time point (P > 0.05).
CONCLUSIONS: The use of the Threading Saw Pliers in PFO is associated with superior perioperative safety, including reduced operating time, less blood loss, and fewer complications, while achieving equivalent mid-term clinical outcomes compared to conventional techniques. The Threading Saw Plier represents a valuable technical advancement for this procedure.
