      Scale (VAS) Pain and Foot and Ankle Ability Measure (FAAM) Scores After Hallux 
      Valgus Surgery.

AB  - BACKGROUND: Minimum clinically important difference (MCID) defines a threshold 
      when determining clinically significant treatment improvement. Visual analog 
      scale (VAS) and Foot and Ankle Ability Measure activities of daily living 
      (FAAM-ADL) are commonly used for measuring hallux valgus correction. This study 
      aimed to determine MCID in VAS pain and FAAM-ADL scores for hallux valgus 
      correction and additionally, to identify variables influencing achievement of the 
      VAS pain MCID. METHODS: Patients undergoing hallux valgus surgery were 
      retrospectively included. VAS pain, FAAM-ADL, and pain satisfaction surveys were 
      collected preoperatively and minimum 1-year postoperatively. Using a 6-point 
      Likert-type pain satisfaction scale, patients reporting low postoperative 
      satisfaction scores 1 through 3 were categorized as "dissatisfied," and high 
      satisfaction scores 4 through six as "satisfied." One distribution-based method 
      and 2 anchor-based methods were used to calculate MCID. Further, a logistic 
      regression was calculated to determine if one group (defined by sex, pain 
      satisfaction, preoperative VAS pain, concomitant lesser toe deformity correction, 
      and specific hallux valgus correction procedure) had a greater likelihood of 
      achieving the VAS pain MCID threshold. This study included 170 patients with 
      postoperative follow-up averaging 23.6 months. RESULTS: Calculated MCID scores 
      ranged from 1.8 to 5.2 points for VAS pain and 11.1 to 22.7 points for FAAM-ADL. 
      Moderate deformity correction with proximal first metatarsal osteotomy (Ludloff) 
      (OR=2.236, P = .036) or severe deformity correction with first tarsometatarsal 
      arthrodesis (Lapidus) (OR=3.145, P = .046); and higher preoperative pain scores 
      (OR=1.045, P < .010) had significantly higher odds of meeting VAS pain MCID. 
      CONCLUSION: This study demonstrated MCID values that may indicate significant 
      pain and function improvement after hallux valgus correction. Higher preoperative 
      pain, and utilization of proximal metatarsal osteotomy or first tarsometatarsal 
      arthrodesis for moderate or severe deformity correction resulted in significantly 
      greater likelihood of reaching the VAS pain MCID than utilizing distal metatarsal 
      and/or proximal phalanx osteotomy for mild deformity treatment. LEVEL OF 
      EVIDENCE: Level IV, validating outcome measures.
