Purpose
To compare revision rates and functional outcomes between patients who underwent staged versus simultaneous bilateral rotator cuff repair (RCR).
Methods
This systematic review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines with no institutional review board approval or funding required. The PubMed, SportDiscus, and Ovid Medline databases were queried to identify original research studies evaluating preoperative characteristics and postoperative outcomes of staged or simultaneous RCR. The following search algorithm was used: ((Bilateral) OR (simultaneous) OR (Staged)) AND (rotator cuff repair). Demographics including the number of male and female patients, age, type of surgical intervention, time between staged surgery, and surgical indication were collected. Variables of interest included pre- and postoperative shoulder pain and functional scores, as well as retear, reoperation, revision, complications, and their rates of occurrence.
Results
Overall, 594 studies were screened, and 8 studies were included in this systematic review. In total, 11,188 patients (97.5%) underwent staged repair and 286 (2.5%) underwent simultaneous repair. Delaying staged surgery by more than 2 years also had decreased surgical complications such as conversion to reverse total shoulder arthroplasty, postoperative infection, venous thromboembolism, and emergency department visits when compared with simultaneous RCR (P ≤ .031) and earlier staging (less than 3 months) (P ≤ .015). In addition, one study found staged RCR had better patient-reported outcome measures (University of California-Los Angeles, Constant, and American Shoulder and Elbow Surgeons scores; P < .001) when staged greater than 9 months apart.
Conclusions
Staged RCR has superior functional outcomes, decreased surgical complications, as well as lower revision rates than simultaneous RCR.
Level of Evidence
Level IV, systematic review of Level II-IV studies.

Purpose
To identify the incidence of lateral meniscal oblique radial tears (LMORTs) concomitant with anterior cruciate ligament (ACL) tears in pediatric patients undergoing ACL reconstruction.
Methods
A single-center retrospective cohort design was used to analyze all patients 18 years and younger undergoing ACL reconstruction between July 2017 and February 2023. Operative notes and intraoperative arthroscopic photos were analyzed to determine the incidence of LMORTs. Two independent observers reviewed the images and reached agreement on LMORT incidence and classification of each tear. Demographic, clinical, and outcomes data were collected and analyzed.
Results
Lateral meniscal oblique radial tears were identified in 19 of 310 (6.13%) adolescent and pediatric ACL reconstruction cases. Of these patients, 68.4% were male. All but one patient had signs of lateral meniscus injury on preoperative magnetic resonance imaging. Of the LMORT patients, 7 (37%) had a type 1 tear, 1 (5%) had a type 2 tear, 7 (37%) had a type 3 tear, and 4 (21%) had a type 4 tear.
Conclusions
Lateral meniscal oblique radial tears were observed concomitantly with ACL tears in 6% of pediatric patients undergoing ACL reconstruction.
Clinical Relevance
Awareness and recognition of LMORTs is important as the treatment paradigm for LMORT injuries continues to evolve.

Purpose
To investigate the improvement in frozen-phase frozen shoulder (FS) patients’ pain and shoulder mobility, including passive forward elevation (FE), external rotation (ER), and internal rotation (IR), after 2 consecutive intra-articular corticosteroid (IACS) injections.
Methods
This retrospective cohort study was performed from July 2020 to November 2023. All patients with frozen-phase FS received 2 ultrasound-guided IACS injections at 6-week intervals. FE, ER, IR, and visual analog scale scores were measured at each follow-up consultation with a 6-week interval.
Results
A total of 134 patients finished the study. There were varying degrees of change in pain relief and range-of-motion improvement between each IACS injection. FE and IR improved significantly between the first and second injections (P = 5.2 × 10−24 and 1.1 × 10−21, respectively), whereas ER only improved significantly after the second injection (P < .05). The pain level improved both after the first injection and after the second injection (both p < .001).
Conclusions
Patients with frozen-phase FS show improved pain, FE mobility, and IR mobility after a single IACS injection. However, a second IACS injection provides similar therapeutic effects and significantly improves ER mobility.
Level of Evidence
Level III, retrospective cohort study.

Purpose
To evaluate the relation between zona orbicularis (ZO) thickness on magnetic resonance imaging and distractibility of the hip in patients undergoing hip arthroscopy.
Methods
We conducted a retrospective review of primary hip arthroscopy patients treated for femoroacetabular impingement syndrome from December 2021 to September 2022. Prior to arthroscopy, hips were subjected to 100 lb of force (lbf) with fluoroscopic images taken to calculate joint space and overall distraction distance. The ZO was measured on coronal sequences of preoperative magnetic resonance imaging or magnetic resonance arthrography. Multivariable linear regression was performed and controlled for age, sex, body mass index, and lateral center-edge angle.
Results
Sixty-eight patients were included in the final analysis. The mean age was 34.5 ± 12.4 years. The mean joint space at 100-lbf axial traction was 11.0 ± 3.8 mm, and the mean distraction distance was 6.6 ± 3.7 mm. The mean ZO size was 3.2 ± 1.0 mm. Linear regression showed no relation between ZO size and joint space at 100 lbf (β = –0.109, R = 0.107, P = .842). The results of our linear regression analysis also showed no significant association between ZO size and overall distraction distance (β = –0.15, R = 0.108, P = .977).
Conclusions
The results of this study show no significant association between ZO size and resistance to axial traction at the hip joint.
Clinical Relevance
Our results suggest that the resistance to axial traction on the hip from the ZO is conferred by its overall integrity and presence—and is not dependent on its size—and that, likely, deviations in other soft-tissue restraints contribute to the spectrum of hip stability experienced by patients.

Purpose
To determine the short-term (30-day) postoperative complication rates in patients undergoing meniscus allograft transplantation (MAT).
Methods
The American College of Surgeons National Surgical Quality Improvement Program database was queried for patients who had undergone MAT from 2014 to 2021 using Current Procedural Terminology codes. Patients were excluded if they did not have sufficient demographic data, namely those without data for age, sex, body mass index, preoperative functional status, American Society of Anesthesiologists classification, operative time, and length of hospital stay. Postoperative complications within 30 days were identified, and rates of complications were examined as the primary outcome of this study. As a secondary outcome, multivariate logistic regression was used to identify risk factors associated with the 30-day incidence of postoperative complications. Subgroup analysis was performed to analyze differences in postoperative outcomes after isolated MAT versus MAT with concomitant ligament reconstruction/repair, cartilage preservation, or realignment osteotomy.
Results
A total of 396 meniscal transplants were identified, with mean age of 35.2 ± 14.9, mean body mass index of 29.6 ± 6.7, mean length of stay of 0.5 ± 1.8 days. Eleven patients experienced any adverse event. Specific complications included surgical-site infections (5), deep-vein thrombosis (1), urinary tract infection (3), and return to the operating room (2). On subgroup analysis, there was no significant difference between any adverse event rates in patients undergoing MAT with concomitant procedures compared with patients undergoing isolated MAT (7 vs 4, P = .5).
Conclusions
Patients who underwent MAT had an overall complication rate of 2.8% in the short-term postoperative period (≤30 days). Patients undergoing MAT with concomitant ligament reconstruction/repair, cartilage preservation, and realignment osteotomy had similar rates of all postoperative complications when compared with patients undergoing isolated MAT.
Level of Evidence
Level IV, therapeutic case series.

Purpose
To characterize radiographic foot/ankle bony abnormalities in elite-level, asymptomatic male basketball athletes and to investigate the association between anthropometric (age, height, weight) or sport-specific characteristics (total exposures, player position, pregame ankle taping) and the prevalence of abnormal radiographic findings in asymptomatic basketball athletes.
Methods
Elite-level basketball players who underwent routine, preseason static radiographic imaging, including anteroposterior, lateral, and mortise views of the ankle were included. Radiographs were collected from asymptomatic athletes participating in preseason history and physical with negative anterior drawer/talar tilt test. Radiographs were evaluated by a musculoskeletal radiologist and board-certified orthopaedic surgeon; kappa statistics were used to evaluate agreement.
Results
Fifty-four basketball players (34 collegiate, 20 professional; mean age 21.5 years) were included, totaling 5,148 player exposures from 2017 to 2019. In total, 106 ankles presented with radiographic findings (98.15%). The most prevalent radiographic finding was pes planus (47.22%), followed by degenerative joint disease (DJD; 33.33%), talonavicular sclerosis (28.70%), prominent stieda process (25.93%), os trigonum (20.93%), os subfibulare (11.11%), pes cavus (5.56%), subtalar coalition (2.78%), and cavovarus (0.93%). Height ≥80 inches was significantly associated with talonavicular sclerosis and Kellgren-Lawrence 1 changes.
Conclusions
This study showed a strong association between height and talonavicular sclerosis and DJD, as well as a relatively high prevalence of pes planus and DJD in asymptomatic collegiate and professional basketball players.
Level of Evidence
Level II; Cross-sectional study.

Purpose
To use a large nationwide administrative database to directly compare usage, complications, and need for revision stabilization surgery after medial patellofemoral ligament reconstruction (MPLFR), tibial tubercle osteotomy (TTO), and combined MPFLR and TTO (MPFLRTTO).
Methods
The PearlDiver Mariner database was queried for all reported cases of MPLFR, TTO, and combined MPFLRTTO performed between 2010 and 2020 using Current Procedural Terminology codes. Subsets from those cohorts with laterality-specific International Classification of Diseases, Tenth Revision, codes for patellar instability were used to evaluate 2-year incidence of infection, stiffness, fracture, and revision stabilization with MPFLR and/or TTO. Multiple linear regression and χ2 analysis were used to analyze incidence trends and to compare complication rates.
Results
A total of 70,070 patients were identified. MPFLR was found to be the most common procedure (73.1%), followed by TTO (19.2%) and then MPFLRTTO (7.6%). MPLFR was observed to have the lowest overall complication rate (5.4%), whereas both TTO (7.5%) and MPFLRTTO (7.1%) had greater complication rates (P < .001). MPFLR had the greatest rate of revision stabilization surgery at 3.7% compared with TTO at 2.7% and MPFLRTTO, which carried the lowest risk for revision at 2.4% (P < .001).
Conclusions
Isolated MPFLR is the most common modality used for patellar instability, with increasing prevalence and the lowest 2-year complication rate. Isolated TTO was unchanged in its use and had the greatest overall complication rate. Combined MPFLRTTO increased the overall complication rate but had a lower 2-year rate of recurrent instability requiring revision than MPFLR alone.

Purpose
To identify key molecular components within the femoroacetabular impingement hip and compare the findings between male and female patients across varying age groups.
Methods
All patients undergoing hip arthroscopy for femoroacetabular impingement syndrome (FAIS) without hip dysplasia were included. During hip arthroscopy, performed at University of Wisconsin Health, loose articular cartilage, excess synovium, damaged labral tissue, and minimal adipose tissue were debrided only as needed for visualization and tissue repair purposes and collected. Tissue was processed and used for quantitative polymerase chain reaction (qPCR). Genes were selected for qPCR on the basis of their associated function in inflammation and/or extracellular matrix remodeling during the progression of osteoarthritis.
Results
A total of 91 male (M) and female (F) patients 15 to 58 years old were included in the study. qPCR results indicated that Interleukin-6 (P < .05, 95% confidence interval [CI] 0.047-0.083 F, 0.070-0.12 M) and Interleukin-8 (P = .04, 95% CI 0.059-0.10 F, 0.082-0.18 M) were significantly greater in male patients compared with female patients regardless of age, and IL6 (P = .02, 95% CI [0.026-0.070] F, [0.067-0.17] M), Interleukin-1ß (P < .01 95% CI [0.013-0.063] F, [0.073-0.25] M), and Matrix metalloproteinase-13 (P = .047, 95% CI [0.0051-0.017] F, [0.0084-0.052] M) were significantly greater in male patients younger than 20 years old compared with female patients younger than 20 years old.
Conclusions
In patients with FAIS, there are significant differences between male and female patients in the biomarkers present in the affected hip at the time of surgery. Male patients have greater levels of IL6 and IL8 and male patients younger than 20 years of age have greater levels of IL1β, IL6, and MMP13 compared with age-matched female patients.
Clinical Relevance
A better understanding of the molecular markers present during varying stages of FAIS and in patients of different ages will help characterize the pathologic process behind FAIS. This may also help define future methods of targeted treatment and prevention of disease progression.

Purpose
To analyze mechanisms, diagnoses, and incidence of youth snowboarding-related injuries presenting to US emergency departments.
Methods
Data from the National Electronic Injury Surveillance System were analyzed for pediatric snowboarding injuries (≤18 years old) from 2012 to 2022. Data were collected for mechanism of injury, diagnosis, location of injury, and disposition. National estimates (NEs) were calculated using the statistical sample weight of the corresponding hospital assigned by the National Electronic Injury Surveillance System. Linear regressions were used to analyze injuries over time.
Results
In total, 3,036 (NEs = 120,140) pediatric snowboarding injuries were included in this study. Average age was 14.0 ± 2.7 years. The most common mechanism of injury was impact with the ground (NEs = 97,120, 80.8%). The most injured body parts were 719 wrists (NEs = 115,505, 96.1%), 580 heads (NEs = 22,258, 18.5%), and 381 shoulders (NEs = 17,269, 14.4%). The most common diagnoses were fractures (NEs = 48,886, 40.7%), strains/sprains (NEs = 22,948, 19.1%), and concussions (NEs = 12,553, 10.4%). Fractures primarily involved the wrist (NEs = 18,122, 37.1%), lower arm (NEs = 12,348, 25.3%), and shoulder (NEs = 9,073, 18.6%). From 2012 to 2022, there were average decreases of 1,051 overall injuries per year (P < .01), 299 fractures per year (P = .04), 298 strains/sprains per year (P < .01), and 143 concussions per year (P < .01). There were average decreases of 784 impact with ground injuries per year (P < .01), 161 not specified injuries per year (P < .01), and 42 impact with inanimate object injuries per year (P = .03) from 2012 to 2022.
Conclusions
Pediatric snowboarding injuries demonstrated a large decline from 2012 to 2022. Fractures are the most common diagnosis, primarily affecting the wrist and shoulder. The head was the second most injured body part, and concussions were the third most common diagnosis.
Clinical Relevance
This study highlights decreasing injuries despite growing popularity of snowboarding, bringing to light the importance of protective equipment, on-site injury management, and implementation of clinics at resort bases.

Purpose
To determine the relationship between cam morphology of the hip and ipsilateral sacroiliac motion compared to the native hip in a cadaveric model.
Methods
A simulated cam state was created using a 3-dimensional printed cam secured to the head-neck junction of 5 cadaveric hips. Hips were studied using a computed tomography–based optic metrology system and a 6 degree-of-freedom robot to exert an internal rotation torque at 3 different torque levels (6 N-m, 12 N-m, 18 N-m). Outcomes included translational and rotational movement about 3 axes and composite (total) translational motion at the ipsilateral sacroiliac (SI) joint. Statistical analysis included a linear mixed model regression with repeated measures.
Results
The presence of a simulated cam was associated with medial motion in the coronal plane (P = .03) and posterior motion in the sagittal plane (P < .01) but not composite motion (P = .37). Motion in the axial plane was in an inferior direction (P = .08). Cam morphology significantly changed rotation in the sagittal plane (P < .01) but not in the coronal (P = .63) or axial plane (P = .18). Composite motion was related to the amount of torque applied to the hip (P < .01). The amount of torque applied to the hip was related to rotation in the coronal plane (P < .01), axial plane (P < .01), and sagittal plane (P < .01) with increased effects as torque increased. Torque was not associated with translation movement in any of the anatomic planes.
Conclusions
The presence of simulated cam morphology is associated with motion in a more medial, inferior, and posterior direction at the ipsilateral SI joint relative to a native state. Increasing torque affects the magnitude of translation, but not its direction, which in this study is primarily influenced by cam morphology.
Clinical Relevance
This biomechanical connection between cam-type femoroacetabular impingement syndrome and the ipsilateral SI joint provides insight into SI joint dysfunction in patients with femoroacetabular impingement syndrome.
