ObjectiveTo explore the clinical application of ultrasound-guided hip joint drug injection in the postoperative rehabilitation of arthroscopie repair of acetabular labral tears.MethodsThis research retrospectively analyzed a total of 38 hips from 36 patients (2 of them were bilateral) whose imaging examination showed acetabular labral well healed but the rehabilitating training was limited due to hip pain after arthroscopie repair of acetabular labral tears in our hospital between June 2015 and May 2017. All the patients underwent ultrasound-guided hip joint drug injection treatment. Through comparing the pain and the function of hip before and after drug injection, the clinical application values of ultrasound-guided hip joint drug injection in the postoperative rehabilitation of arthroscopie repair of acetabular labral tears were explored. The degree of hip pain was assessed by visual analogue score (VAS), which were scored before and after the injection. The hip function was assessed by the hip range of activity. The SPSS 21.0 statistical software was used for the data analysis. The effective rate of hip injection was calculated, which was defined as: ("excellent" + "good")/total number of cases×100%. The degree of hip pain was assessed by VAS, which was divided into 0 to 10 points with 0 for no pain and 10 for unbearable severe pain. The function of hip was assessed by the hip range of activity. The therapeutic effect of "excellent" meant no pain or occasional slight pain in the hip, along with Patrick test was negative and hip joint was not limited; the therapeutic effect of "good" meant that the pain was significantly reduced, and the hip's activity was slightly restricted. "No effect" meant that the pain of hip was not relieved, and the Patrick test was positive.ResultsThe VAS score of the patient before drug injection was 5.46±1.46, and the VAS score was 2.01±0.53 after drug injection 4 weeks later. The score of the latter was significantly lower than that of the former, and the difference was statistically significant (P<0.05). The hip joint activity after ultrasound-guided hip joint drug injection was significantly improved. The therapeutic effective rate was 84.2%.ConclusionFor patients with hip pain and limitations after arthroscopie repair of acetabular labral tears, ultrasound-guided drug injection can effectively reduce hip pain, improve hip activity, and promote hip functional reconstruction.
