PURPOSE: To analyze the relationship between functional outcomes and postoperative cuff integrity (anatomic outcome), and to reveal the factors affecting outcomes of rotator cuff repair. METHODS: Seventy-eight patients who had undergone repair of full-thickness rotator cuff tear received both computed tomographic arthrography (CTA) and functional evaluation a minimum of 1 year after surgery. The mean follow-up period was 19.6 months (range, 12 to 39 months). Anatomic outcome was evaluated by CTA

PURPOSE: The purpose of this study was to determine whether moderate preoperative shoulder stiffness affects the clinical outcome of rotator cuff repair, and to evaluate the serial change in range of motion (ROM), functional scores, pain, and satisfaction after rotator cuff repair. METHODS: Rotator cuff repair was performed in 125 consecutive patients (127 shoulders). Thirty patients had concomitant moderate shoulder stiffness at the time of the repair. There were no statistical differences in s

BACKGROUND: There are numerous reports on the outcome of rotator cuff repair according to age. However, the results are conflicting and driven by univariate analysis, which is not free of confounding factors. HYPOTHESIS: Age does not affect the anatomical and functional outcomes of rotator cuff repair. STUDY DESIGN: Case series; Level of evidence, 4. MATERIALS AND METHODS: Eighty-one men and 96 women underwent rotator cuff repair at one institution and received computed tomography arthrography a

BACKGROUND: Repair tension of a torn rotator cuff can affect healing after repair. However, a measurement of the actual tension during arthroscopic rotator cuff repair is not feasible. The relationship between repair tension and healing of a rotator cuff repair remains unclear. PURPOSE/HYPOTHESIS: The purpose of this study was to evaluate the effect of repair tension on healing at the repair site. The hypothesis was that repair tension would be a major factor in determining the anatomic outcome

BACKGROUND: Selective cyclooxygenase (COX)-2 inhibitors are commonly used analgesics that provide similar analgesia as that of other analgesics but with fewer adverse effects. However, few prospective studies have performed comparative analyses in this regard. PURPOSE: To evaluate the efficacy of a selective COX-2 inhibitor in early postoperative pain control, satisfaction with pain management, and incidence of systemic adverse effects in patients undergoing arthroscopic rotator cuff repair. STU

BACKGROUND: Bioabsorbable anchors may lead to osteolysis and cyst formation. However, the prevalence of these outcomes is not known for rotator cuff repairs. PURPOSE: To evaluate cyst formation after placement of bioabsorbable anchors for rotator cuff repairs and to verify whether bioabsorbable anchors degraded as intended and preserved bone stock for possible revision compared with metal anchors. The null hypothesis was that the rate and severity of cyst formation around the anchor are negligib

BACKGROUND: There are numerous accessory portals for the arthroscopic repair of superior labral anterior and posterior lesions. Many surgeons are reluctant to make a portal through the cuff because of concern about iatrogenic injury to the cuff. HYPOTHESIS: An arthroscopic superior labral anterior and posterior lesion repair procedure using the trans-rotator cuff portal may yield favorable clinical and radiological outcomes, and cuffs may heal properly. STUDY DESIGN: Case series; Level of eviden

BACKGROUND: Biodegradable anchors may lead to perianchor cyst formation or osteolysis. A new generation of anchors containing osteoconductive material was recently presented, but there is currently no solid evidence that this concept decreases cyst formation around anchors. HYPOTHESIS: The null hypothesis was that the prevalence and severity of cyst formation around anchors would be similar for all 3 anchor types. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: To evaluate differences

OBJECTIVES:: To evaluate the clinical efficacy of smartphone-assisted self-rehabilitation in patients with frozen shoulder. DESIGN:: A single-center, randomized controlled trial. SETTING:: Orthopedic department of a university hospital. SUBJECTS:: A total of 84 patients with frozen shoulder were recruited. INTERVENTION:: Patients were randomly divided into two groups: a smartphone-assisted exercise group ( n = 42) and a conventional self-exercise group ( n = 42). The study was performed over thr

PURPOSE: To evaluate the prevalence of proximal vertebral artery stenosis, compared wiith those of the distal vertebral/basilar artery and extracranial internal carotid artery, in a large population of stroke and non-stroke patients. MATERIAL AND METHODS: Nine-hundred-and-thirty-five patients who underwent high-resolution contrast-enhanced magnetic resonance angiography in a regional general hospital were categorized into six groups based on neurological symptoms and disease: an asymptomatic gro

PURPOSE: The aim of this study was to compare the effect of postoperative pain control and adverse effects of intravenous patient-controlled analgesia (IV PCA) and multimodal shoulder injection after arthroscopic rotator cuff repair. METHODS: Seventy patients scheduled for elective arthroscopic rotator cuff repair were prospectively randomized to receive either IV PCA or multimodal shoulder injections. Postoperative pain, nausea, vomiting, and other adverse effects were assessed at 2, 6, 12, 24,
