Clinical efficacy of arthroscopy combined with irrigation and drainage in the treatment of brucellosis of the hip.

PURPOSE: To evaluate the short-term clinical efficacy of hip arthroscopy combined with catheter irrigation and drainage in the treatment of brucellosis of the hip.

METHODS

From 2015 to 2020, 11 patients with a diagnosis of brucellosis-induced unilateral hip joint arthritis were treated with arthroscopic debridement and lesion synovectomy. Catheterization was performed during the operation, and normal saline lavage was continued after the operation. A regimen of doxycycline plus rifampicin, plus a third-generation cephalosporin in cases of refractory infections, were used for three months.

RESULTS

The rate of positive synovial bacterial culture during the operation was 91% (10/11). Postoperative pathological examination of 11 patients showed purulent arthritis; this result combined with the disease history led to the diagnosis of all patients with brucellosis of the hip. All patients were followed up for more than 24 months. From three months after surgery to the last follow-up, both ESR and CPR were within the normal range, but the VAS score decreased significantly (P < 0.05), and the mHHS and HOS-ADL scores increased significantly (P < 0.01). Compared with that on preoperative imaging, the measurement of the hip joint space on imaging at the last follow-up showed no significant change (P > 0.01).

CONCLUSION

Arthroscopic treatment of brucellosis in the hip joint not only preserves the joint fluid and lesion tissue for a clear diagnosis but also allows thorough removal of the infected and injured tissue during surgery. Hip arthroscopy combined with postoperative tube irrigation and drainage is an effective method for the diagnosis and treatment of brucellosis in the hip joint.
