Investigate the optimal timing for weight bearing after Hallux Valgus surgery. Hypothesis: Early weight bearing does not affect outcome after the Endoscopic Distal Soft Tissue Procedure for Hallux Valgus Correction.
Introduction: * Rehabilitation plans after hallux valgus/bunion surgery is varied * From a patient's perspective, full weight bearing is paramount for quality of life and return to work/study * No high-level study showing the optimal time to resume full weight bearing available Hypothesis: Early weight bearing (at 2 weeks post-op) does not affect outcome after the Endoscopic Distal Soft Tissue Procedure for Hallux Valgus correction Trial Design: * Parallel group * Random allocation * Operating Surgeon blind to randomisation Study Setting: * General Regional Hospital * Single Centre

Hallux Valgus Angle as a Measure of the Radiological Changes
Weight bearing feet X-Ray to measure radiological parameters of hallux valgus. A larger angle represents the more severe condition. This is the angle between the 1st metatarsal and the proximal phalanx.
Time frame: 0, 12, 26 weeks post-surgery
Inter-metatarsal Angle as a Measure of the Radiological Changes
Weight bearing feet X-Ray to measure radiological parameters of hallux valgus. A larger angle represents the more severe condition. This is measure using the bisecting line between the 1st metatarsal and the 2nd metatarsal.
Time frame: 0, 12, 26 weeks post-surgery
Radiological Changes (Tibial Sesamoid Position)
Weight bearing feet X-Ray to measure radiological parameters of hallux valgus. 4 represents the most neutral position. bigger difference from 4 means more severe condition. This a score from 0-7.
Time frame: 0, 12, 26 weeks post-surgery
Foot Function (FAOS Symptoms)
Calculation of foot function using the self-reported Foot and Ankle Outcome Score (FAOS): FAOS consists of 5 subscales; Pain, other Symptoms, Function in daily living (ADL), Function in sport and recreation (Sport and Recreation), and foot and ankle-related Quality of Life (QOL). The last week is taken into consideration when answering the questionnaire. Standardized answer options are given (% Likert boxes) and each question gets a score from 0 to 4. A normalized score (100 indicating no symptoms and 0 indicating extreme symptoms) is calculated for each subscale.
Time frame: 0, 12, 26 week post-surgery
Foot Function (FAOS Pain)
Calculation of foot function using the self-reported Foot and Ankle Outcome Score (FAOS): FAOS consists of 5 subscales; Pain, other Symptoms, Function in daily living (ADL), Function in sport and recreation (Sport and Recreation), and foot and ankle-related Quality of Life (QOL). The last week is taken into consideration when answering the questionnaire. Standardized answer options are given (% Likert boxes) and each question gets a score from 0 to 4. A normalized score (100 indicating no symptoms and 0 indicating extreme symptoms) is calculated for each subscale.

Foot Function (FAOS ADL)

Foot Function (FAOS Sport)
Calculation of foot function using the self-reported Foot and Ankle Outcome Score (FAOS): FAOS consists of 5 subscales; Pain, other Symptoms, Function in daily living (ADL), Function in sport and recreation (Sport and Recreation), and foot and ankle-related Quality of Life (QOL).
