Brief summary

Exploring the factors influencing postoperative functional recovery after high tibial osteotomy

Detailed description

A retrospective study was conducted on patients who underwent HTO at the First Affiliated Hospital of Shandong First Medical University from January 2018 to December 2020, and the preoperative and postoperative imaging indicators \[medial proximal tibial angle (MPTA), joint line intersection angle (JLCA), hip-knee-ankle angle (HKA angle), knee weight-bearing line percentage (WBL%), postoperative distraction distance, postoperative distraction angle\] and knee joint function score \[including the American Hospital for Special Surgery (HSS) knee score, American Knee Society score (KSS), Lysholm score, Western Ontario and McMaster Universities Osteoarthritis Index score (WOMAC), and all were included in logistic regression analysis to study the surgical effect and impact of HTO factor
