| Patients all had undergone arthrocentesis as outpatients. |
| Both arthroscopy and arthrocentesis have comparable postoperative complication rates. |
| Surgical interventions include arthrocentesis, arthroscopy, and open joint surgery. |
| Arthrocentesis of the hip is traditionally performed in the fluoroscopy suite by interventional radiologist or in the operating room by orthopaedic surgeons. |
| Does ultrasound guidance improve the outcomes of arthrocentesis and corticosteroid injection of the knee? |
| Conclusions: Although patients benefitted from both techniques, arthrocentesis with injection of SH seemed to be superior to arthrocentesis alone. |
