ABSTRACT
Objective:
To evaluate the value of ultrasound-guided intra-articular anesthetic injection in predicting postoperative outcomes for borderline developmental hip dysplasia (BDDH).Methods:
A follow-up study. The clinical data of 37 BDDH patients who received ultrasound-guided intra-articular anesthetic injection and arthroscopic examination in the Department of Sports Medicine, Senior Department of Orthopedics, the Fourth Medical Center of PLA General Hospital from May 2018 to February 2021 were retrospectively analyzed. Among them, there were 17 males and 20 females with a mean age of (37.9±12.8) years. All patients underwent ultrasound-guided intra-articular anesthetic injection prior to arthroscopy, and were evaluated with hip physical examination before and after injection, as well as before and after arthroscopy, in order to obtain the visual analog score (VAS) of pain for seven assessments. The total VAS score was calculated based on these evaluations. Follow-up was conducted for at least 12 months. The effective rate of injection referred to the ratio of the improvement of VAS score after anesthetic injection to the total VAS score before injection. Pearson correlation analysis and Bland-Altman analysis were used to test the correlation between modified Harris hip score (mHHS) after ultrasound-guided intra-articular anesthetic injection and mHHS score after arthroscopic surgery. A binary logistic regression model was established to analyze the substantial clinical benefit (SCB) for patients. Following the logistic regression analysis, a receiver operating characteristic (ROC) curve was constructed to evaluate the predictive power of ultrasound-guided intra-articular anesthetic injection in achieving SCB in those patients. The optimal cut-off value for injection efficacy was determined based on the ROC curve when SCB was achieved.Results:
The follow-up time for all patients was (26.3±7.6) months. After anesthetic injection for 20 minutes, the total VAS score of pain [M(Q1,Q3)] decreased from 13(8,23) points before injection to 1(0,4) points; and the mHHS score [M(Q1,Q3)] increased from 60(46,70) points before arthroscopy to 90(84,96) points after, with statistically significant differences before and after injection and before and after arthroscopy (both P<0.001). Pearson correlation analysis showed that the mHHS score after intra-articular anesthetic injection was positively correlated with the mHHS score after surgery (r=0.961, P<0.001). The area under the ROC curve for predicting SCB after arthroscopy with ultrasound-guided intra-articular anesthetic injection was 0.769 (95%CI 0.561-0.976), the Youden index was 0.663, the cut-off value was 0.569 2, the sensitivity was 96.3%, and the specificity was 70.0%.Conclusions:
The results of ultrasound-guided intra-articular anesthetic injection before arthroscopy can indicate the presence of intra-articular lesions, and the degree of pain relief after injection is proportional to the functional recovery after arthroscopy. Patients with intra-articular anesthetic injection efficacy>56.92% have better results in hip arthroscopy.
