Bleeding disorder increases the risks of complications following arthroscopic rotator cuff repair.

Background: It is imperative to determine patients' risk factors prior to arthroscopic rotator cuff repair (ARCR), so that the physician and patient are both aware of the possible postoperative complications. However, the impact of bleeding disorders on a patient's short-term postoperative outcome has not yet been analyzed.

Methods: A national database was queried for patients undergoing ARCR from 2006 to 2018.

The cumulative incidence and risk factors associated with 5-year conversion to knee arthroplasty following primary meniscus repair or primary meniscectomy.

Background: This study aimed to observe the 5-year knee arthroplasty conversion incidence rate and associated risk factors in patients who underwent meniscus procedures.

Methods: Using a national database, we analyzed patients who had undergone primary meniscus repair or meniscectomy without prior knee surgeries. The cumulative knee arthroplasty conversion incidence was determined via Kaplan Meier analysis.

Trends in utilization of meniscal allograft transplantation between 2010 and 2019.

Objectives: The aim of this study was to observe the trends in (1) utilization of meniscus allograft transplantation (MAT), (2) demographics and comorbidities of patients undergoing transplants and (3) reimbursements for this procedure between the years of 2010 and 2019.

Methods: Using a national database, patients who underwent MAT were observed. Incidence of MAT, percentage of female patients, average age, and average Charlson comorbidity index (CCI) were analyzed between 2010 and 2019.

Delay of Timing of Anterior Cruciate Ligament Reconstruction Is Associated With Lower Risk of Arthrofibrosis Requiring Intervention.

Purpose: To conduct 2 separate stratum-specific likelihood ratio analyses in patients younger than 40 year of age (<40 years) and those aged 40 and older (40+ years) at time of anterior cruciate ligament (ACL) reconstruction to define data-driven strata between ACL tear and primary isolated ACL reconstruction in which the risk of arthrofibrosis, using manipulation under anesthesia and arthroscopic lysis of adhesions as surrogates, is significantly different.

Methods: A retrospective cohort analysis was conducted using the PearlDiver Database. Patients who underwent ACL reconstruction were identified using the Current Procedure Terminology code 29888.

Anticoagulant Usage After Anterior Cruciate Ligament Reconstruction Is Associated With Increased Rate of Manipulation Under Anesthesia.

Background: Arthrofibrosis after anterior cruciate ligament reconstruction (ACLR) is a notable but uncommon complication of ACLR. To improve range of motion after ACLR, aggressive physical therapy, arthroscopic/open lysis of adhesions, and revision surgery are currently used. Manipulation under anesthesia (MUA) is also a reasonable choice for an appropriate subset of patients with inadequate range of motion after ACLR.

Shoulder, upper arm and elbow injuries in high school men's American football.

In order to reduce shoulder, upper arm and elbow injury rates in American football, identifying injury risk factors and any underlying associations is needed. No prior study has done such characterization at the high school level. A descriptive epidemiology study was performed using data from the National Athletic Treatment, Injury, and Outcomes Network Surveillance Program (NATION-SP) from the years 2011/12 to 2013/14 on high school football athletes.

The effect of obesity on complications following isolated posterior cruciate ligament reconstruction.

Background: This study assessed the risk of 30-day complications for obese patients compared to non-obese patients undergoing isolated posterior cruciate ligament (PCL) reconstruction.

Methods: From 2006 to 2019, the National Surgical Quality Improvement Program database was queried for patients undergoing isolated PCL reconstruction. Two patient cohorts were defined: patients with obesity (BMI ≥ 30.

The association between diabetes status and postoperative complications for patients receiving ACL reconstruction.

Purpose: It is well established that diabetes is associated with complications following surgical procedures across the wide array of surgical subspecialties. The evidence on the effect of diabetes on postoperative outcomes following anterior cruciate ligament (ACL) reconstruction (ACLR), however, is not as robust, and findings have not been consistent. It was hypothesized that patients with diabetes are at increased risk of complications and a higher rate of hospital admission following ACLR.

Comparison of Arthroscopy versus Open Arthrotomy for Treatment of Septic Arthritis of the Native Knee: Analysis of 90-Day Postoperative Complications.

Septic arthritis is an orthopaedic emergency, often necessitating surgical debridement, and the knee joint is most frequently affected. Arthroscopic and open irrigation and debridement (I&D) are the two commonest surgical treatments for septic arthritis of the native knee. Several studies have compared outcomes of open and arthroscopic management without coming to a clear conclusion which yields superior outcomes.

Comparison of 30-day complications between reverse shoulder arthroplasty and open reduction internal fixation for the treatment of proximal humerus fractures.

Purpose: While the use of open reduction internal fixation (ORIF) has remained stable over the last decade, there has been a significant increase in the use of reverse total shoulder arthroplasty (RTSA) for proximal humerus fractures (PHFs). This study sought to compare the complication profiles of RTSA to ORIF in a large, validated, retrospective cohort.

Methods: Patients who underwent surgical treatment for PHFs with RTSA or ORIF were identified in a national database (NSQIP) using CPT and ICD codes.

Isolated Carpal Dislocation of the Pisiform with Distal Radius Fracture in Two Adults: A Rare Entity.

 Pisiform dislocations are an extremely rare injury. There are reports in the literature of isolated dislocations, but to our knowledge there are no reports of distal radius fractures with associated pisiform dislocations.  We present two cases of isolated pisiform dislocation and distal radius fracture in the adult population.

Diagnosis of Culture-Negative Septic Arthritis with Polymerase Chain Reaction in an Immunosuppressed Patient: A Case Report.

Case: We present a 23-year-old woman on immunosuppressive therapy with polyarticular, culture-negative septic arthritis. She underwent irrigation and debridement with empiric antibiotic therapy but had recurrence of septic arthritis despite treatment. Polymerase chain reaction testing eventually identified Ureaplasma as the causative organism.

Deep Vein Thrombosis after Cement Intravasation during Hip Hemiarthroplasty.

Cement intravasation occurs in hemiarthroplasty when pressurization of cement through the medullary canal backflows through the nutrient vessels. This case report describes a 70-year-old woman who underwent hip hemiarthroplasty for a displaced left femoral neck fracture. Postoperative radiographs demonstrated radio-opacity consistent with local cement intravasation.

No change in performance metrics in major league baseball players sustaining wrist fractures after being struck by an errant pitch.

Objective: This study aimed to determine the effect of wrist fractures on performance metrics in Major League Baseball Players after they were hit by an errant pitch.

Methods: Players who sustained wrist fractures after being struck by a pitch were identified and changes in performance metrics were calculated.

Results: In both the short- and medium-term analysis, there were no significant differences in all pre- and post-injury offensive statistics following return to play.
