This study aimed to determine whether there are significant differences in 30-day perioperative complications between arthroscopic and open débridement (irrigation and débridement [I&D]) for septic arthritis (SA) of the shoulder using the American College of Surgeons National Surgical Quality Improvement Program database. Patients undergoing arthroscopic or open I&D of the native shoulder from 2006-2016 were identified in the National Surgical Quality Improvement Program database. Those with a diagnosis of SA were included in the study. Patients with a concurrent diagnosis of osteomyelitis around shoulder (n = 25) or polyarthritis (n = 2) were excluded from the study. Patient demographics, comorbidities, and complications were compared between the groups. Poisson regression, which controlled for age and American Society of Anesthesiologists (ASA) score, was used to calculate the relative risks with 95% confidence intervals for minor adverse events, serious adverse events, total adverse events, and unplanned reoperations between the 2 treatment groups, with significance set at P <.0125 after Bonferroni correction. Overall, 147 and 57 patients underwent arthroscopic and open I&D, respectively, for SA of the shoulder. Patients in the open I&D group were more likely to be smokers (P =.0213), whereas patients in the arthroscopy group had higher ASA scores (P =.0008). After controlling for age and ASA score, we found no significant differences in the risk of minor adverse events (P =.0995), serious adverse events (P =.2241), total adverse events (P =.1871), or unplanned reoperations (P =.3855). Arthroscopic débridement appears to be a safe alternative to open débridement for SA of the native shoulder. The incidence and risk of 30-day perioperative complications are similar after arthroscopic and open I&D for SA of the shoulder. [ABSTRACT FROM AUTHOR]

There is no standard to determine the most appropriate method of operation for the treatment of acute septic arthritis of the shoulder joint. We retrospectively reviewed 57 patients who underwent arthroscopic or open débridement for acute shoulder infection between 2001 and 2015. Arthroscopic débridement was performed in 27 patients, and open débridement in 30 patients. According to the presence of bone erosion and/or marginal erosion of cartilage of the humeral head on plain radiographs and magnetic resonance imaging (MRI) images, the cases were classified into 3 groups (group 1, n = 23, without erosions in x-ray and MRI; group 2, n = 21, erosions seen in MRI but not in x-ray; and group 3, n = 13, with erosions seen in both x-ray and MRI). The arthroscopic group had a reinfection rate of 55.6% (15/27), and the open group had a reinfection rate of 16.7% (5/30). The reinfection rates in the arthroscopic and the open groups were 10% (1/10) and 15.4% (2/13) in group 1; 75% (9/12) and 11.1% (1/9) in group 2; and 100% (5/5) and 25% (2/8) in group 3, respectively. At the last follow-up, the mean University of California at Los Angeles score and the average time until normalization of white blood cell, erythrocyte sedimentation rate, and C-reactive protein in the open group showed superior results in the open group (all P <.05). When preoperative MRI showed bone and/or cartilage erosion of humeral head, the reinfection rate after arthroscopic débridement was above 75%. Therefore, if preoperative MRI showed erosions, open débridement is more likely to be appropriate than arthroscopic débridement. [ABSTRACT FROM AUTHOR]

Abstract: The success of open irrigation and debridement with component retention (ODCR) for acute periprosthetic knee joint infection varies widely. The species and virulence of the infecting organism have been shown to influence outcome. This multicenter, retrospective study identified 19 cases of acute periprosthetic methicillin-resistant Staphylococcus aureus (MRSA) knee infections managed by ODCR and at least 4 weeks of postoperative intravenous vancomycin therapy. At minimum follow-up of 2 years, the treatment failed to eradicate the infection in 16 cases (84% failure rate). Of those 16 failures, 13 patients required a 2-stage exchange arthroplasty, 2 patients required repeat incision and debridement with antibiotic suppression, and 1 patient died of MRSA sepsis. In addition, a systematic review of the literature revealed failure to eradicate infection in 10 of 13 patients managed with a similar protocol. The total success rate of ODCR in acute periprosthetic MRSA knee infection was 18%. [Copyright &y& Elsevier]

Purpose: The goal of this study was to compare open and arthroscopic surgical techniques for “cam-type” femoroacetabular impingement in terms of feasibility and reliability. Methods: We used 5 fresh-frozen cadaver specimens (10 hips). Anteroposterior and cross-table radiographs were taken for each. The head-neck union diameter was measured for each. The amount of bone resection at the anterolateral quadrant of the head-neck union was planned for each, with specific references to width, length, depth, and position. One side was randomly assigned to the open group and the other to the arthroscopic group. Surgical time, position of the osteotomy, and variation of the length, width, and depth of the final osteotomy with respect to the proposed dimensions were compared. Results: In all specimens partial resection of the anterior-lateral femoral head-neck junction with improvement of the femoral head-neck offset was accomplished. A statistically significant difference (P < .05) was observed for surgical time between the open and arthroscopic groups (shorter in open group). Conclusions: When comparing surgical precision, no statistically significant differences were found between the open and arthroscopic procedures in any of the measurements. The depth and width of the osteoplasty were reliably obtained by the arthroscopic technique. However, there was a tendency to underestimate the osteoplasty length with the arthroscopic procedure. Positioning the osteoplasty was also less reliable with the arthroscopic procedure than with the open procedure because of the tendency to place the osteoplasty more posterior and distally than intended. Clinical Relevance: Surgical resection of the femoral neck prominence and/or part of the anterolateral neck has been reported to improve femoral head offset and alleviate impingement. This study attempts to document the accuracy of this resection when done arthroscopically compared with an open procedure. [Copyright &y& Elsevier]
