Osteoarthritis In Total Knee Arthroplasty Treatment Of High-Risk Factors Affecting The Analysis And Research

Objective:To explore the high risk factors that affect the rehabilitation of patients after TKA, and to provide the index and reference for suitable surgery method, reducing clinical risk and realizing good prognosis.Methods:Made retrospective analysis of knee osteoarthritis patients’data in our hospital from May 2009 to November 2013. All of the patients were diagnosed with Holden IV pathological abnormality. There were altogether 113 cases, including 78 male and 35 female, aged form 39-78, with the average age of 58.5 years old. There were 84 obese patients (76-129kg), accounting 74.33%. The number of left TKA patients were 48, while the right one were 65. All patients used posterior stabilized knee joint prosthesis with patellar replacement.By collecting the data of preoperative patient’s HSS scores and followed them up for a period of 4-26 months. The high risk factors of postoperative rehabilitation of the TKA are collected, processed and analyzed, which includes the patient’s age, sex, medical history, pathological data, preoperative and postoperative HSS scores, rehabilitation compliance. Used single factor analysis and Logistic multi-factor regression analysis method to analyze all the factor’s variable and finally find out the high risk factors which affect the rehabilitation efficacy after TKA.Results:1.To analyze the influence of age, gender, BMI on the rehabilitation of patients with knee and osteoarthritis, it can be concluded that the P value of the age is 0.386, gender is 0.915 and BMI is 0.456. Therefore, age, gender and BMI are not related to the HSS grade(p>0.05).2. To analyze the influence of pre-operative HHS grade, post-operative comlications and postoperative rehabilitation compliance on the rehabilitation of patients with knee and osteoarthritis, it can be concluded that the P value of pre-operative HHS grade is 0.007, the post-operative comlications is 0.000 and the Postoperative rehabilitation compliance is 0.021. There was a positive correlation between pre-operative HHS grade, post-operative comlications, Postoperative rehabilitation compliance and postoperative HSS grade(P<0.05).3. According to the analysis of multi factors in patients with knee and osteoarthritis rehabilitation after TKA, it has been discovered that among the patients with knee and osteoarthritis, those with higher preoperative HSS grade, less postoperative comlications and good postoperative rehabilitation compliance can get better results in TKA. Moreover, pre- TKA HSS grade, postoperative comlications and postoperative rehabilitation compliance are high rish factors and all of them are independent (has no effect on each other).Conclusion:1. Among the analysis of single factor that influence the TKA rehabilitaion of patients with knee and osteoarthritis, it can be concluded that age, gender and BMI are not related to postoperative HSS grades, thus not high rish factors. Pre-TKA HSS grade, postoperative comlications, postoperative rehabilitation compliance and preoperative HSS grade, thus as high rish factors. According to the analysis of multi factors in patients with knee and osteoarthritis rehabilitation after TKA, it can be further confimed that Pre-TKA HSS grade, postoperative comlications, postoperative rehabilitation compliance are high rish factors and all of them are independent (has no effect on each other).2. By found treatment to improve the peroperative HSS grades and driving prevention and treatment to the postoperative complications, and improving patients’ postoperative rehabilitation compliance, TKA can achieve good outcomts and clinical effect.
