RESUMO
BACKGROUND: While stiffness of the lumbosacral spine is a known predictor of instability following total hip arthroplasty (THA), little is known about the medical- and surgical-related outcomes following THA in patients who have prior isolated sacroiliac (SI) joint arthrodesis. METHODS: 197 patients who had a history of isolated SI joint arthrodesis who subsequently underwent elective primary THA for a diagnosis of osteoarthritis (THA-SI) from 2015 to 2021 were identified in a national administrative database. Using propensity score matching and logistic regression analyses, this cohort was compared to two groups of patients: patients who did not have any history of lumbar or SI arthrodesis and patients undergoing primary THA who had a history of lumbar arthrodesis without extension into the SI joint (THA-LF). RESULTS: The THA-SI group had a significantly higher incidence of dislocation (odds ratio 2.06, 95% confidence interval 1.04-4.04, P = .037) with no increased incidence of medical complications or other surgical complications when compared to patients without a history of SI or lumbar arthrodesis. There were no significant differences in any complications in THA-SI patients when compared to THA-LF patients. CONCLUSION: Patients who had prior isolated SI joint arthrodesis undergoing primary THA demonstrated a two-fold increased incidence of dislocation when compared to those who did not have prior SI arthrodesis, although the risk of complications in this population was similar to that observed in patients who had prior isolated lumbar spine arthrodesis.

Background: Recent research has found a high rate of emergency department (ED) use after lower extremity arthroplasty; one study found a risk factor for ED presentation after lower extremity arthroplasty was presentation to the ED in the year prior to surgery. It is not known whether a similar association exists for total shoulder arthroplasty (TSA). Questions/Purposes: The goal of this study was to investigate the relationship between preoperative ED visits and postoperative ED visits after anatomic TSA. Methods: The 100% Medicare database was queried for patients who underwent anatomic TSA from 2005 to 2014. Emergency department visits within the year prior to the date of TSA were identified. Patients were additionally stratified by the number and timing of preoperative ED visits. The primary outcome measure was one or more postoperative ED visits within 90 days. A multivariate logistic regression analysis was used to control for patient demographics and comorbidities. Results: Of the 144,338 patients identified, 32,948 (22.8%) had an ED visit in the year prior to surgery. Patients with at least 1 ED visit in the year before surgery presented to the ED at a significantly higher rate than patients without preoperative ED visits (16% versus 6%). An ED visit in the year prior to TSA was the most significant risk factor for postoperative ED visits (in the multivariate analysis). The number of preoperative ED visits in the year prior to surgery demonstrated a significant dose-response relationship with increasing risk of postoperative ED visits. Conclusions: Postoperative ED visits occurred in nearly 10% of Medicare patients who underwent TSA in the period studied. More frequent presentation to the ED in the year prior to anatomic TSA was associated with increasing risk of postoperative ED visits. Future studies are needed to investigate the reasons for preoperative ED visits and if any modifiable risk factors are present to improve the ability to risk stratify and optimize patients for elective TSA.
RESUMO
BACKGROUND: Large (4.5 mm) and/or transpatellar bone tunnels have been associated with patellar fracture after medial patellofemoral ligament (MPFL) reconstruction. To avoid this outcome, many surgeons now employ suture anchors to affix the MPFL graft to the patella. PURPOSE: To evaluate the risk of patellar fracture and other outcomes associated with smaller (3.2-mm), short, oblique patellar tunnels as compared with suture anchor fixation in MPFL reconstruction. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: A single institution's electronic medical record was queried for all patients undergoing MPFL reconstruction between March 2010 and December 2018. A chart review of operative reports was utilized to identify those who had undergone MPFL reconstruction. Patients undergoing revision MPFL reconstruction or reconstruction with fully transpatellar bone tunnels were excluded. The incidence of patellar fracture and outcomes were evaluated from chart review. The mean duration of follow-up was >2 years. RESULTS: A total of 384 knees in 352 patients undergoing primary MPFL reconstruction were identified. Small (3.2-mm), short, oblique tunnels were used for patellar fixation in 215 cases, and suture anchors were utilized in 169 cases. The small, oblique tunnels and suture anchor techniques both resulted in a low incidence of patellar fracture, with rates of 0.47% and 0%, respectively. The use of suture anchors was associated with an increased risk of subluxation or dislocation compared with small, oblique tunnels (odds ratio, 3.98; P = .028). No significant difference was found in the need for revision MPFL reconstruction surgery with suture anchors (odds ratio, 1.925; P = .66). CONCLUSION: The use of small, oblique tunnels with hamstring autograft is a safe means of patellar fixation in MPFL reconstruction. The use of small, oblique tunnels for patellar fixation versus 2 suture anchors can result in material cost savings with no significantly increased risk for fracture as well as an overall reduction in complication rates.
RESUMO
PURPOSE: To examine any association between osteoporosis and the failure of arthroscopic rotator cuff repair (ARCR) leading to revision surgery and to investigate whether the use of bisphosphonates had any influence on the observed associations. METHODS: Patients who underwent ARCR with a diagnosis of osteoporosis were identified from the PearlDiver database and stratified according to whether there was a filled prescription for a bisphosphonate in the perioperative period. Patients with osteoporosis who underwent ARCR with bisphosphonate use were compared with age- and sex-matched patients who underwent ARCR with osteoporosis without a prescription for a bisphosphonate within 1 year of surgery and patients who underwent ARCR without a diagnosis of osteoporosis and no bisphosphonate use. The primary outcome measure was ipsilateral revision rotator cuff surgery, including revision repair, debridement for a diagnosis of a rotator cuff tear, or reverse shoulder arthroplasty. A multivariable logistic regression analysis was used to control for patient demographic characteristics and comorbidities during comparisons. RESULTS: We identified 2,706 patients, including 451 in the bisphosphonate study group; 902 in the osteoporosis, no-bisphosphonate control group; and 1,353 in the non-osteoporosis control group. Patients with osteoporosis, including those to whom bisphosphonates were prescribed, had a significantly higher rate of revision rotator cuff surgery (6.58%) than patients without osteoporosis (4.51%) (odds ratio, 1.60; 95% confidence interval, 1.30-1.97; P = .008). No significant difference in the rate of revision surgery was found between patients with osteoporosis using bisphosphonates (6.65%) and age- and sex-matched patients with osteoporosis not using bisphosphonates (6.54%, P = .718). CONCLUSIONS: By using an administrative database, this study was able to show a substantial difference in the revision surgery rate after ARCR in patients with osteoporosis compared with matched controls. LEVEL OF EVIDENCE: Level III, retrospective cohort study.

BACKGROUND: A few investigations exist which evaluate the influence of obstructive sleep apnea (OSA) on complications after arthroscopic rotator cuff repair. METHODS: A database was queried for patients undergoing rotator cuff repair with and without OSA and further subdivided into those with and without a billing code for a continuous positive airway pressure (CPAP) device. Thirty-day and 6-month adverse events were assessed. RESULTS: After regression analysis, patients with OSA had markedly increased emergency department visits and hospital admission (P < 0.05). This risk was mitigated by CPAP orders compared with control subjects. Patients without CPAP use had markedly increased risks of emergency department visits, hospital admission, and respiratory complications compared with control subjects (P < 0.05). CONCLUSIONS: Patients with OSA have higher risks of emergency department visits and hospital admissions postoperatively; however, a CPAP order appears to mitigate this risk. The independent risk imparted by OSA for the studied complications was markedly lower than other comorbidities.

PURPOSE: To determine the association between glycemic control and adverse events after arthroscopic rotator cuff repair (RCR). METHODS: Patients with a diagnosis of diabetes mellitus who underwent arthroscopic RCR and had a hemoglobin A1c (HbA1c) level determined within 3 months before or after surgery were identified in a national database and stratified by HbA1c level. The incidence of postoperative infection within 6 months was determined using Current Procedural Terminology and International Classification of Diseases, Ninth Revision codes. A receiver operating characteristic (ROC) curve analysis was performed to determine whether a threshold HbA1c level existed above which the risk of infection, revision rotator cuff surgery, and lysis of adhesions (LOA)-manipulation under anesthesia (MUA) after arthroscopic RCR was significantly increased. This threshold was then tested using a logistic regression analysis. RESULTS: The study included 3,740 patients with an infection rate ranging from a low of 0.29% to a high of 1.14% after RCR. The inflection point of the ROC curve for infection corresponded to an HbA1c level between 7.0 and 8.0 mg/dL (P = .035; area under the curve, 0.648; specificity, 61%; sensitivity, 59%). We then used 8.0 mg/dL as a threshold to test for adverse outcomes. We found a significant difference in infection rates for patients with levels below versus above the threshold (0.30% vs 0.84%; OR, 2.0; 95% confidence interval, 1.2-3.4; P = .014) but no difference in revision rates (P = .240) or LOA-MUA (P = .650) in patients with levels above versus below the threshold. CONCLUSIONS: The risk of infection after RCR in patients with diabetes mellitus increases as the perioperative HbA1c level increases and, although statistically significant, remains low. ROC curve analysis determined that a perioperative HbA1c level above 8.0 mg/dL could serve as a threshold level; however, the area under the curve and low sensitivity reflected the poor utility of this test as an independent predictor. This study did not find an association between increased perioperative HbA1c levels and rates of revision rotator cuff surgery or LOA-MUA after RCR. LEVEL OF EVIDENCE: Level III, retrospective cohort study.

BACKGROUND: The goals of the study were to determine (1) the incidence of dialysis patients undergoing shoulder arthroplasty (SA), (2) the association of dialysis modality with complications after SA, and (3) the association of dialysis dependence with death in patients undergoing SA and nonsurgical dialysis-dependent controls. METHODS: Using an insurance database, we identified dialysis-dependent patients undergoing SA and compared them with a matched control cohort without dialysis use. We performed an analysis comparing patients using peritoneal dialysis (PD), patients using hemodialysis (HD), matched non-dialysis-dependent controls, and matched PD and HD nonsurgical patients. Complications including in-hospital death, emergency department visits, hospital readmission, infection, and revision surgery were assessed. RESULTS: The incidence of SA in dialysis patients has significantly increased. Compared with controls, dialysis-dependent patients had increased rates of in-hospital death (odds ratio [OR], 7.60; P < .0001), emergency department visits (OR, 4.16; P < .0001), hospital admission (OR, 1.63; P < .0001), and infection within 1 year (OR, 1.90; P = .009). Compared with patients receiving HD, PD patients had lower rates of death (OR, 0.40; P = .008), hospital readmission (OR, 0.43; P = .047), and revision surgery (OR, 0.23; P = .037). as well as a lower incidence of infection (OR, 0.30; P = .018). Compared with controls, PD patients had similar rates of most complications. Compared with nonsurgical dialysis-dependent patients, the SA procedure itself was not associated with an increased mortality rate. CONCLUSIONS: Although dialysis represents a significant independent risk factor for complications after SA, this risk is highly influenced by the type of dialysis.

BACKGROUND: Patients are seeking out medical information on the Internet and utilizing smartphone health applications ("apps"). Smartphone use has exponentially increased among orthopaedic surgeons and patients. Despite this increase, patients are rarely directed to specific apps by physicians. No study exists querying patient preferences for a patient-centered, orthopaedic smartphone application. OBJECTIVES: The purpose of this study is to 1) determine Internet use patterns amongst orthopaedic patients; 2) ascertain access to and use of smartphones; and 3) elucidate what features orthopaedic patients find most important in a smartphone application. METHODS: We surveyed patients in an orthopaedic practice in an urban academic center to assess demographics, access to and patterns of Internet and Smartphone use, and preferences for features in a smartphone app. RESULTS: A total of 310 surveys were completed. Eighty percent of patients reported Internet access, and 62% used the Internet for health information. Seventy-seven percent owned smartphones, 45% used them for health information, and 28% owned health apps. Only 11% were referred to an app by a physician. The highest ranked features were appointment reminders, ability to view test results, communication with physicians, and discharge instructions. General orthopaedic information and pictures or videos explaining surgery were the 2 lowest ranked features. Seventy-one percent of patients felt an app with some of the described features would improve their healthcare experiences, and 40% would pay for the app. CONCLUSIONS: The smartphone is an under-utilized tool to enhance patient-physician communication, increase satisfaction, and improve quality of care. Patients were enthusiastic about app features that are often included in patient health portals, but ranked orthopaedic educational features lowest. Further study is required to elucidate how best to use orthopaedic apps as physician-directed educational opportunities to promote patient satisfaction and quality of care.
