A comparison of conventional ultrasonography and arthrosonography in the assessment of cuff integrity after rotator cuff repair.

Background: This study was designed to perform conventional ultrasonography, magnetic resonance arthrography (MRA) and arthrosonography exams after rotator cuff repair to compare the results of conventional ultrasonography and arthrosonography with those of MRA as the gold standard.

Methods: We prospectively studied 42 consecutive patients (14 males, 28 females; average age, 59.4 years) who received arthroscopic rotator cuff repair due to full-thickness tears of the supraspinatus tendon from 2008 to 2010.

Clinical and radiological evaluation after arthroscopic rotator cuff repair using suture bridge technique.

Background: We retrospectively assessed the clinical outcomes and investigated risk factors influencing retear after arthroscopic suture bridge repair technique for rotator cuff tear through clinical assessment and magnetic resonance arthrography (MRA).

Methods: Between January 2008 and April 2011, sixty-two cases of full-thickness rotator cuff tear were treated with arthroscopic suture bridge repair technique and follow-up MRA were performed. The mean age was 56.

Ceramic-on-ceramic total hip arthroplasty: minimum of six-year follow-up study.

Background: This study examines the clinical and radiologic results of ceramic-on-ceramic total hip arthroplasties with regard to wear, osteolysis, and fracture of the ceramic after a minimum follow-up of six years.

Methods: We evaluated the results of a consecutive series of 148 primary ceramic-on-ceramic total hip arthroplasties that had been performed between May 2001 and October 2005 in 142 patients. The mean age was 57.

Two continuous femoral nerve block strategies after TKA.

Purpose: The purposes of this study were to compare the pain score, systemic opioid consumption, and range of motion (ROM) between the group where the use of continuous femoral nerve block (CFNB) was discontinued on postoperative day 3 (POD 3) and the group where it was discontinued on POD 7 within an established clinical pathway for postoperative recovery after total knee arthroplasty (TKA) and to assess the treatment-related side effects and complications, as well as the functional status of these two groups of patients at 2 years after surgery.

Methods: This prospective, randomized, double-blinded trial compared the analgesic efficacy and the functional outcomes between group A (n = 30) where continuous femoral nerve block was performed until POD 3 (discontinued prior to the initiation of range of motion (ROM) exercises) and group B (n = 33), where the continuous femoral nerve block was performed until POD 7 (discontinued during the ROM exercise) after TKA.

Results: The resting pain scores of group B were lower than those of group A but there was no significant difference between the two groups (n.
