BACKGROUND:Remplissage is a useful adjunct to repair of the anteroinferior glenoid labrum in the treatment of anterior shoulder instability. This study aimed to compare costs and clinical outcomes between isolated arthroscopic Bankart repair (ABR) and ABR with remplissage. METHODS:This was a retrospective study of all patients who underwent arthroscopic treatment of anterior shoulder instability between June 2011 and August 2021. Patient, procedural factors, and clinical outcome data were collected. Financial data was reported as "relative costs". The best fit circle method was utilized on MRI to estimate glenoid bone loss (GBL) and the Hill Sachs Interval (HSI). Using the glenoid track, patients were determined to either have 'on' or 'off' track lesion. RESULTS:48 patients who underwent ABR alone and 49 patients who underwent ABR with remplissage were matched and included in analysis. There was no significant difference in total cost, mean number of dislocations, ED visits, or revision surgery between isolated ABR and ABR with remplissage. The remplissage cohort had a significantly higher rate of "off-track" lesions (24.5% vs. 6.2%, p = 0.013), % GBL (8.7% vs. 5.7%, p = 0.015) and Hill Sachs lesion size (16.7 ± 4.1 mm vs. 8.9 ± 6.9 mm, p < 0.001). CONCLUSION/CONCLUSIONS:No differences in total cost were found between ABR with or without addition of remplissage. Clinical outcomes were similar in both groups, despite a significant increase in the number of off-track lesions, HSI and GBL seen in the remplissage group. Surgeons may consider addition of remplissage in the appropriate clinical context with low concern of increased cost. LEVEL OF EVIDENCE/METHODS:Level 3.

Recent orthopedic literature has shown that primary repair for femoral-sided avulsion tears of the anterior cruciate ligament (ACL) can be successful. Primary ACL repair avoids invasive reconstruction techniques, graft-site morbidity, and the loss of native anatomy while producing excellent results in appropriately selected patients. Here we describe our patient selection parameters, ACL repair technique, and rehabilitation protocol.

Anterior cruciate ligament (ACL) injury affects a large number of athletes worldwide, and long-term rate of return to soccer is approximately 50% or less. ACL injury, which is noncontact in approximately 90% of cases, has a complex multifactorial etiology. Younger and higher-level players do better, and 10-year outcomes are superior to baseline. The role of genomics, hormonal status, neuromuscular deficiencies, anatomy, and the environment are all potential contributory risk factors that vary with respect to the individual, especially the female athlete. Furthermore, ACL injury results in a local and regional catabolic cascade and cytokine release, creating an intra-articular environment that is a homeostatic perfect storm and spectrum of scalable articular cartilage and meniscal injury. Once these complexities in the knee organ are defined and understood, the surgeon's early objectives are stabilization, repair, and restoration with full harmonization of biomechanics, neuromuscular control, and homeostasis. The goal is optimizing long-term outcomes, decreasing the rate of subsequent ACL injury, and preventing osteoarthritis.

BACKGROUND:The use of the direct anterior approach has been criticized as a significant risk factor for subsidence, perioperative fracture, and thigh pain. Therefore, the purpose of our study was to evaluate the outcome of using the center-center technique via the direct anterior approach. MATERIALS AND METHODS:Consecutive elective primary total hip arthroplasties performed using the center-center technique were retrospectively reviewed from May 2015 to February 2017. All cases were performed by a single surgeon at a high-volume, large academic center. The technique focuses on central alignment of the implant on both anteroposterior and lateral radiographs. Standardized objective radiographic measurements were taken at the first two-week follow-up visit to determine the fit and fill at the proximal and distal anatomic segments. Subsidence was measured by comparing the implant position at final follow up to the initial two-week postoperative visit. Other complications: intra- or postoperative fracture, infection, revision, and patient-reported thigh pain were further assessed. Functional postoperative outcomes were assessed using the Harris Hip Score (HHS). RESULTS:A total of 138 patients with a mean age of 65 years and average follow up of 2.8 years were assessed. The mean postoperative HHS was 90 points (59-100). Mean implant subsidence was 1mm. A total of 90% (124) of implants had acceptable radiographic fit and fill in both proximal and distal segments. A majority 74% (102) of implants subsided less than 1mm, and 91% (126) subsided less than 2mm. One implant had radiographic subsidence of 9mm, which was treated with a shoe lift. There were no intraoperative fractures. One postoperative lateral cortex fracture three weeks after surgery due to mechanical fall was treated conservatively. No patients required revision arthroplasty for any reason or reported postoperative thigh pain. CONCLUSION:The center-center technique can be used to consistently aid in proper femoral stem placement in both coronal and sagittal planes. Optimal fit and fill can be achieved safely using this technique.

Obturator hip dislocations are rare, typically resulting from high-energy trauma in native hips. These types of dislocations are treated with closed reduction under sedation. Open reduction and internal fixation may be performed in the presence of associated fractures. Still rarer are obturator hip dislocations that penetrate through the obturator foramen itself. These types of dislocations have only been reported three other times in the literature, all within native hips. To date, there have been no reports of foraminal obturator dislocations after total hip arthroplasty. We report of the first periprosthetic foraminal obturator hip dislocation, which was caused iatrogenically during attempts at closed reduction of a posterior hip dislocation in the setting of a chronic greater trochanter fracture. Altered joint biomechanics stemming from a weak hip abductor mechanism rendered the patient vulnerable to this specific dislocation subtype, which ultimately required open surgical intervention. An early assessment and identification of this dislocation prevented excessive closed reduction maneuvers, which otherwise could have had detrimental consequences including damage to vital intrapelvic structures. This case report raises awareness to this very rare, yet potential complication after total hip arthroplasty.

The patient experience domain comprises a significant portion of the Hospital Value-Based Purchasing program. This study investigated whether an intervention focusing on attending physician awareness, resident and physician assistant education, and multidisciplinary patient-centric care had an effect on patient perceived physician communication and overall hospital ratings. Responses to the Hospital Consumer Assessment of Healthcare Providers and Systems survey were reviewed in 2014 and 2015. Patients' perceptions that the physician explained their condition in ways they understood and the overall hospital rating improved significantly after implantation of the model ( P < .05). Patient-physician communication is important for high-quality health care and is becoming increasingly more important in hospital economics. These methods may serve as a protocol for other institutions to improve the patient experience.

Favorable patient experience and low complication rates have been proposed as essential components of patient-centered medical care. Patients' perception of care is a key performance metric and is used to determine payments to hospitals. It is unclear if there is a correlation between technical quality of care and patient satisfaction. The study authors correlated patient perceptions of care measured by the Hospital Consumer Assessment of Healthcare Providers and Systems scores with accepted quality of care indicators. The Hospital Compare database (4605 hospitals) was used to examine complication rates and patient-reported experience for hospitals across the nation in 2011. The majority of the correlations demonstrated an inverse relationship between patient experience and complication rates. This negative correlation suggests that reducing these complications can lead to a better hospital experience. Overall, these results suggest that patient experience is generally correlated with the quality of care provided.

A thorough knowledge of the principles of antibiotic stewardship is a crucial part of high-quality orthopaedic surgical care. These principles include (1) determining appropriate indications for antibiotic administration, (2) choosing the correct antibiotic based on known or expected pathogens, (3) determining the correct dosage, and (4) determining the appropriate duration of treatment. Antibiotic stewardship programs have a multidisciplinary staff that can help guide antibiotic selection and dosage. These programs also perform active surveillance of antimicrobial use and may reduce Clostridium difficile and other drug-resistant bacterial infections by providing expert guidance on judicious antibiotic usage. The emergence of antibiotic-resistant pathogens, the geographical diversity of these infecting pathogens, and the changing patient population require customization of prophylactic regimens to reduce infectious complications. A multidisciplinary approach to antibiotic stewardship can lead to improved patient outcomes and cost-effective medical care.

There has been a substantial shift in the assessment of outcomes in medicine, including orthopaedic surgery. The quality movement is redefining the delivery of health care. The effect of these changes on orthopaedic surgery and orthopaedic surgeons has been significant and will become increasingly important. Orthopaedic surgeons must become active participants in the quality movement by understanding the basic principles of the movement and how they apply to patient care. A clear understanding of the different agencies (governmental and private) that are leading these initiatives is also essential. Ultimately, active participation in the quality movement will enhance the care provided to patients with musculoskeletal disorders.
