Abstract
Aim: We aimed to explore the threshold of preoperative range of motion (ROM) and flxion contacture (FC) as a predictor of Poor knee function after TKA.
Method: A retrospective analysis was conducted on 84 Patients with haemophilia (PWH) (113 knees) who underwent knee arthroplasty in our hospital from January 2010 to December 2020 (mean follow-up 70.7 ± 22.4 months). General information, hemophilia information, surgical information, follow-up information were collected. Knees were divided into two groups: Group poor (41 knees) and Group excellent (72 knees). In the clinical evaluation, the FC, ROM and American Society Knee clinical Score (KSC), American Society Knee functional Score (KSF), Hospital for Special Surgery (HSS) scores were used preoperatively and at the final follow-up visit. Receiver operating characteristics (ROC) analysis was used to analyze the threshold of preoperative ROM and FC as a predictor of Poor knee function after TKA.
Result: Postoperative knee joint KSC, KSF, and HSS scores, as well as ROM and reduction in FC deformities at the last follow-up, improved significantly compared to preoperative levels. A notable correlation was observed between ROM and FC and the outcome of knee arthroplasty. The cutoff value of preoperative fexion contracture and ROM for poor knee function at last-follow up was 16.5° and 61.5°.
Conclusion: The study concludes that the efficacy of knee joint replacement surgery in hemophilia patients is influenced by the pre-ROM and Pre-FC. The better the pre- ROM, the better the knee efficacy. The greater the pre- flexion contracture degree, the worse the knee efficacy.
期刊介绍：
Evidence of surgical interventions go back to prehistoric times. Since then, the field of surgery has developed into a complex array of specialties and procedures, particularly with the advent of microsurgery, lasers and minimally invasive techniques. The advanced skills now required from surgeons has led to ever increasing specialization, though these still share important fundamental principles.
Frontiers in Surgery is the umbrella journal representing the publication interests of all surgical specialties. It is divided into several “Specialty Sections” listed below. All these sections have their own Specialty Chief Editor, Editorial Board and homepage, but all articles carry the citation Frontiers in Surgery.
Frontiers in Surgery calls upon medical professionals and scientists from all surgical specialties to publish their experimental and clinical studies in this journal. By assembling all surgical specialties, which nonetheless retain their independence, under the common umbrella of Frontiers in Surgery, a powerful publication venue is created. Since there is often overlap and common ground between the different surgical specialties, assembly of all surgical disciplines into a single journal will foster a collaborative dialogue amongst the surgical community. This means that publications, which are also of interest to other surgical specialties, will reach a wider audience and have greater impact.
The aim of this multidisciplinary journal is to create a discussion and knowledge platform of advances and research findings in surgical practice today to continuously improve clinical management of patients and foster innovation in this field.
