RESUMO
Background: Female athletes are at increased risk for anterior cruciate ligament (ACL) injuries. The influence of hormonal variation on female ACL injury risk remains ill-defined. Recent data suggests that the collagen-degrading menstrual hormone relaxin may cyclically impact female ACL tissue quality. This review aims to identify any correlation between menstrual relaxin peaks and rates of female ACL injury. Methods: A systematic review was performed, utilizing the MEDLINE, EMBASE, and CINAHL databases. Included studies had to directly address relaxin/female ACL interactions. The primary outcome variable was relaxin proteolysis of the ACL, at cellular, tissue, joint, and whole-organism levels. The secondary outcome variable was any discussed method of moderating relaxin levels, and the clinical results if available. Results: AllThe numerous relaxin receptors on female ACLs upregulate local collagenolysis and suppress local collagen production. Peak serum relaxin concentrations (SRC) occur during menstrual cycle days 21-24; a time phase associated with greater risk of ACL injury. Oral contraceptives (OCPs) reduce SRC, with a potential ACLprotective effect. Conclusion: A reasonable correlative and plausible causative relationship exists between peak relaxin levels and increased risk of ACL injury in females, and further investigation is warranted. Level of Evidence: III.

For decades, surgeons have utilized 0.9% normal saline (NS) for joint irrigation to improve visualization during arthroscopic procedures. This continues despite mounting evidence that NS exposure impairs chondrocyte metabolism and compromises articular cartilage function. We hypothesized that chondrocyte oxidative stress induced by low pH is the dominant factor driving NS toxicity, and that buffering NS to increase its pH would mitigate these effects. Effects on chondrocyte viability, reactive oxygen species (ROS) production, and overall metabolic function were assessed. Even brief exposure to NS caused cell death, ROS overproduction, and disruption of glycolysis, pentose phosphate, and tricarboxylic acid (TCA) cycle pathways. NS also stimulated ROS overproduction in synovial cells that could adversely alter the synovial function and subsequently the entire joint health. Buffering NS with 25 mM 4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid (HEPES) significantly increased chondrocyte viability, reduced ROS production, and returned metabolite levels to near control levels while also reducing ROS production in synovial cells. These results confirm that chondrocytes and synoviocytes are vulnerable to insult from the acidic pH of NS and demonstrate that adding a buffering agent to NS averts many of its most harmful effects.

It is unclear if bracing is necessary after isolated medial patellofemoral ligament reconstruction (MPFLr) for recurrent patellar instability. We hypothesize that patients who did not use a brace will have similar outcomes to those who were braced postoperatively. A retrospective review of patients who underwent isolated MPFLr from January 2015 to September 2020 at a single institution was performed. Those with less than 6 weeks of follow-up were excluded. The braced group was provided a hinged-knee brace postoperatively until the return of quadriceps function, which was determined by the treating physical therapist (brace, "B"; no brace, "NB"). Time to straight leg raise (SLR) without lag, recurrent instability, and total re-operations were determined. Univariate analysis and logistic regression were used to evaluate outcomes (statistical significance, p < 0.05). Overall, 229 isolated MPFLr were included (B: 165 knees, 146 patients; NB: 64 knees, 58 patients). Baseline demographics were similar (all p > 0.05). Median time to SLR without lag was shorter in the NB group (41 days [interquartile range [IQR]: 20-47] vs. 44 days [IQR: 35.5-88.3], p = 0.01), while return to sport times were equivalent (B: 155 days [IQR: 127.3-193.8] vs. NB: 145 days [IQR: 124-162], p = 0.31). Recurrent instability rates were not significantly different (B: 12 knees [7.27%] vs. NB: 1 knee [1.56%], p = 0.09), but the re-operation rate was higher in the brace group (20 knees [12.1%] vs. 0 [0%], p = 0.001). Regression analysis identified brace use (odds ratio [OR]: 19.63, 95% confidence interval [CI]: 1.43-269.40, p = 0.026) and female patients (OR: 2.79, 95% CI: 1.01-7.34, p = 0.049) to be associated with needing reoperation. Recurrent instability rates and return to sport times were similar between patients who did or did not use a hinged knee brace after isolated MPFLr. Re-operation rates were higher in the braced group. Retrospective Comparative Study, Level III.

An updated understanding of unicompartmental knee arthroplasty (UKA) utilization is needed. The purpose of this study was to evaluate temporal trends in volume and utilization of UKA among early-career surgeons and to examine the influence of fellowship training status on utilization of UKA. The American Board of Orthopaedic Surgery (ABOS) Part-II database was queried from 2010 to 2019 to identify candidates who reported ≥1 total knee arthroplasty (TKA) or UKA. Self-reported history of fellowship training experiences was recorded. "High-volume" surgeons were defined as performing ≥7 UKA over the ABOS Part-II collection period. Trends were evaluated with the Cochrane-Armitage test and generalized linear models. From 2010 to 2019, a total of 2,045 candidates (28.1%) reported ≥1 TKA, while 585 candidates (8.0%) reported ≥1 UKA. The number of candidates reporting ≥1 UKA significantly increased (p = 0.001). An increase in UKA volume was observed over the study period (p < 0.001). Rates of utilization of UKA relative to TKA did not change significantly over the study period (p = 0.11). Sixty-three (2.4%) candidates met the study definition for high-volume UKA utilization. UKA procedure volume increased among ABOS Part-II candidates over the study period; however, rates of UKA utilization relative to TKA volume remained unchanged. Increasing volume of UKA performed by early-career surgeons is likely secondary to an increased number of surgeons trained in adult reconstruction. Only 2.4% of candidates who reported performing at least one knee arthroplasty procedure met the threshold for a high-volume UKA practice. Early-career surgeons should remain conscientious of UKA volume in their practice.

Background: Patients undergoing elective procedures often utilize online educational materials to familiarize themselves with the surgical procedure and expected postoperative recovery. While the Internet is easily accessible and ubiquitous today, the ability of patients to read, understand, and act on these materials is unknown. Purpose: To evaluate online resources about anterior cruciate ligament (ACL) surgery utilizing measures of readability, understandability, and actionability. Study Design: Cross-sectional study; Level of evidence, 4. Methods: Using the term "ACL surgery," 2 independent searches were performed utilizing a public search engine (Google.com). Patient education materials were identified from the top 50 results. Audiovisual materials, news articles, materials intended for advertising or medical professionals, and materials unrelated to ACL surgery were excluded. Readability was quantified using the Flesch Reading Ease, Flesch-Kincaid Grade Level, Simple Measure of Gobbledygook, Coleman-Liau Index, Automated Readability Index, and Gunning Fog Index. The Patient Education Materials Assessment Tool for Printable Materials (PEMAT-P) was utilized to assess the actionability and understandability of materials. For each online source, the relationship between its Google search rank (from first to last) and its readability, understandability, and actionability was calculated utilizing the Spearman rank correlation coefficient (ρS). Results: Overall, we identified 68 unique websites, of which 39 met inclusion criteria. The mean Flesch-Kincaid Grade Level was 10.08 ± 2.34, with no website scoring at or below the 6th-grade level. Mean understandability and actionability scores were 59.18 ± 10.86 (range, 33.64-79.17) and 34.41 ± 22.31 (range, 0.00-81.67), respectively. Only 5 (12.82%) and 1 (2.56%) resource scored above the 70% adequate PEMAT-P threshold mark for understandability and actionability, respectively. Readability (lowest P value = .103), understandability (ρS = -0.13; P = .441), and actionability (ρS = 0.28; P = .096) scores were not associated with Google rank. Conclusion: Patient education materials on ACL surgery scored poorly with respect to readability, understandability, and actionability. No online resource scored at the recommended reading level of the American Medical Association or National Institutes of Health. Only 5 resources scored above the proven threshold for understandability, and only 1 resource scored above it for actionability.
RESUMO
Background: The incidence of anterior cruciate ligament (ACL) injuries in skeletally immature patients is increasing, with ACL reconstruction preferred in this population due to reported chondroprotective benefits. Due to concerns with growth disturbance following ACL reconstruction in skeletally immature patients, various physealsparing and partial transphyseal techniques have been developed. Currently, there is no consensus on the most effective ACL reconstruction technique in skeletally immature patients. The purpose of the current study was to report the outcomes of a partial-transphyseal over-the-top (OTT) ACL reconstruction in a cohort of skeletally immature patients. Methods: All patients with radiographic evidence of open tibial and femoral physes that underwent primary ACL reconstruction using a partial-transphyseal OTT technique between 2009-2018 at a single tertiary-care institution with at least twelve months of clinical follow-up were retrospectively reviewed. Patient demographics, physical examination findings, graft ruptures, return to sport, and Tegner activity levels were analyzed. Statistical significance was defined as p<0.05. Results: Overall, 11 males and 1 female (12 knees) with a mean age of 12.8±1.8 (range: 10-16) years were included in the study. The mean postoperative follow-up of the cohort was 2.3±1.2 (range: 1.1-5.2) years. All ACLs were reconstructed with hamstring autograft with allograft augmentation utilized in a single patient. There were two cases of ACL graft rupture (16.7%). All patients were able to return to the same or higher level of sporting activity at an average of 7.4+2.7 months. There were no cases of clinically significant longitudinal or angular growth disturbance. Conclusion: Partial transphyseal ACL reconstruction using a transphyseal tibial tunnel and an extra-articular OTT technique on the femur in skeletally immature patients affords minimal risk of growth disturbance with a graft rupture rate consistent with what has been reported in this high-risk population. All patients were able to return to sport at the same or higher level. Level of Evidence: IV.

Background: Rotational ankle fractures are common injuries associated with high rates of intra-articular injury. Traditional ankle fracture open reduction and internal fixation (ORIF) techniques provide limited capacity for evaluation of intra-articular pathology. Ankle arthroscopy represents a minimally invasive technique to directly visualize the articular cartilage and syndesmosis while aiding with reduction and allowing joint debridement, loose body removal, and treatment of chondral injuries. The purpose of this study was to evaluate temporal trends in concomitant ankle arthroscopy during ankle fracture ORIF surgery amongst early-career orthopaedic surgeons while examining the influence of subspecialty fellowship training on utilization. Methods: The American Board of Orthopaedic Surgery (ABOS) Part II Oral Examination database was queried to identify all candidates performing at least one ankle fracture ORIF from examination years 2010 to 2019. All ORIF cases were examined to identify those that carried a concomitant CPT code for ankle arthroscopy. Concomitant ankle arthroscopy cases were categorized by candidates self-reported fellowship training status and examination year. Descriptive statistics were performed to report relevant data and linear regression analyses were utilized to assess temporal trends in concomitant ankle arthroscopy with ORIF for ankle fractures. Statistical significance was defined as p<0.05. Results: During the study period, there were 36,113 cases of ankle fracture ORIF performed of which 388 cases (1.1%) were performed with concomitant ankle arthroscopy. Ankle fracture ORIF was most frequently performed by trauma fellowship trained ABOS Part II candidates (n=8,888; 24.6%), followed by sports medicine (n=7,493; 20.8%) and foot and ankle (n=6,563; 18.2%). Arthroscopy was most frequently utilized by foot and ankle fellowship trained surgeons (293/6,270 cases; 4.5%) followed by sports medicine (29/7,464 cases; 0.4%) and trauma (4/8,884 cases; 0.1%). With respect to arthroscopic cases, 293 cases (75.5%) were performed by foot and ankle fellowship trained surgeons, 29 (7.5%) sports medicine, and 4 (1.0%) trauma. Ankle arthroscopy utilization significantly increased from 3.65 cases per 1,000 ankle fractures in 2010 to 13.91 cases per 1,000 ankle fractures in 2019 (p=0.010). Specifically, foot and ankle fellowship trained surgeons demonstrated a significant increase in arthroscopy utilization during ankle fracture ORIF over time (p<0.001; OR: 1.101; CI: 1.054-1.151). Conclusion: Ankle arthroscopy utilization during ankle fracture ORIF has increased over the past decade. Foot and ankle fellowship trained surgeons contribute most significantly to this trend. Level of Evidence: IV.

Medial patellofemoral ligament (MPFL) reconstruction has proven to be a reliable procedure to reduce patellar instability events in patients with recurrent patellar instability. As our reconstruction techniques have evolved to address pathology in a diverse patient population, there continues to be an obsessive focus on the precise anatomy of the MPFL origin on the medial knee, due in large part to concerns that improper femoral tunnel position may result in excessive graft anisometry and failure. However, recurrent patellar instability involves many complexities and should not be simply reduced to a single point on the medial knee.

PURPOSE: To compare postoperative pain and recovery after anterior cruciate ligament reconstruction (ACLR) in patients who received an adductor canal block (ACB) or periarticular local infiltrative anesthesia (LIA). METHODS: A retrospective review of a prospectively collected ACL registry was performed. Patients underwent ACLR at a single institution between January 2015 and September 2020 and received long-acting local anesthesia with a preoperative ultrasound-guided ACB or periarticular LIA after surgery. Visual analog scale (VAS) pain scores, milligram morphine equivalents (MME) consumed in the post-anesthesia care unit (PACU), and total hospital recovery time were compared. Univariate analysis was used to compare VAS pain and MME totals between overall groups and groups propensity score matched for age, sex, body mass index, graft type, and meniscal treatment. Results are presented as mean (95%CI) unless otherwise indicated. RESULTS: There were 265 knees (253 patients) included (LIA, 157 knees; ACB, 108 knees). Overall, VAS pain scores before hospital discharge (LIA: 2.6 [2.4-2.8] vs ACB: 2.4 [2.1-2.7]; P = .334) and total MMEs were similar (LIA: 17.6 [16.4-18.8] vs ACB: 18.5 [17.2-19.8] (MME); P =.134). Median time to discharge also did not significantly differ (LIA: 137.5 [IQR: 116-178] vs. ACB: 147 [IQR: 123-183] (min); P = .118). Matched subanalysis (LIA and ACB; n = 94) did not reveal significant differences in VAS pain before discharge (LIA: 2.4 [2.1-2.7] vs ACB: 2.7 [2.4-3.0]; P = .134) or total MMEs (LIA: 18.6 (17.2-20.0) vs ACB: 17.9 (16.4-19.4); P = .520). CONCLUSION: The use of ACB or LIA resulted in similar early pain levels, opioid consumption, and hospital recovery times after ACLR surgery. LEVEL OF EVIDENCE: III, retrospective comparison study.

The purpose of this study was to describe the pattern of meniscus and cartilage pathology in multiligament knee injuries (MLKIs) and determine the relationship between surgical timing and injury mechanism with degree of intra-articular injury. Patients with surgically treated MLKIs over a 15-year period were retrospectively reviewed and grouped based on surgical intervention, time to intervention, and injury mechanism. The presence or absence of meniscus and chondral injury were recorded at the time of surgery. Surgical intervention within 6 weeks of injury was deemed acute, while surgery occurring more than 6 weeks from injury was classified as delayed. Over the 15-year study period, 207 patients with MLKIs were identified. Compared with acutely managed patients, the delayed intervention group had significantly more meniscus (p = 0.03) and cartilage (p < 0.01) pathology. Meniscus injury rates in MLKIs sustained during sporting activity did not differ from nonsporting injuries (p = 0.63). However, the nonsporting group had significantly more chondral injuries (p < 0.01). High-energy injury mechanism was associated with increased cartilage (p = 0.02), but not meniscus (p = 0.61) injury rates. In conclusion, surgical reconstruction of MLKIs delayed for more than 6 weeks was associated with increased meniscus and cartilage pathology.

BACKGROUND: To evaluate the relationship between femoral version (FV) and α angle (AA) in a large osteological collection of human femurs. METHODS: The University of Iowa-Stanford osteological collection was used to evaluate the research aims. To measure FV and AA, axial photographs of the proximal femurs were taken, referenced from the posterior condylar axis. FV and AA measurements were obtained using ImageJ software, and the relationship between FV and AA was assessed with repeated-measures analysis of variance and generalized linear models. A P value of <.05 was considered statistically significant. RESULTS: A total of 1321 cadaveric femurs (666 left and 655 right) in 721 cadavers were examined. The average AA for all femurs was 47.8° ± 10.9°, and the average FV for all femurs was 8.53° ± 8.09°. Overall, 191 femurs (14.5%) exhibited cam morphology (AA ≥ 60°). Of the 721 cadavers, 600 had both femurs available for side-to-side comparison. The average FV of femurs with cam morphology was significantly higher than that of femurs without cam morphology (11.70° ± 8.82° vs. 7.99° ± 8.82°, P < .001). Linear regression analysis demonstrated that increased AA was significantly correlated with increased FV (ß ± standard error of the mean = 0.21 ± 0.02, P < .0001). CONCLUSION: In a large osteological collection of human femurs, a significant positive relationship between AA and increasing FV was identified. CLINICAL RELEVANCE: FAI and hip impingement morphology are more complex than cam or pincer morphology. Cam morphology with high femoral anteversion may allow for normal or near-normal hip mechanics without impingement, and this may partially explain the high rates of asymptomatic cam-type femoroacetabular impingement (FAI) morphology in active and general populations. Given the multiple morphological factors implicated in the development of FAI syndrome, these findings warrant further investigation.

Background: The Patient-Reported Outcomes Measurement Information System (PROMIS®) was designed to monitor the global wellbeing of patients, with the Physical Function Computer-Adaptive Test (PF-CAT) component focused specifically on functional outcome. PROMIS aims for increased item-bank accuracy, lower administrative burden, and decreased floor and ceiling effects compared to legacy patient-reported outcome measures (PROMs). Our primary research outcomes focused on sports medicine surgical populations, which may skew younger or have wide-ranging functional statuses. Specifically, for this population, we questioned if PROMIS PF-CAT was equal to legacy PROMs in (1) construct validity and (2) convergent/divergent validities; and superior to legacy PROMs with respect to (3) survey burden and (4) floor and ceiling effects. Methods: Searches were performed in April 2019 in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, utilizing PubMed, Cochrane Central, and Embase databases for Level I-III evidence. This resulted in 541 records, yielding 12 studies for inclusion. PROM data was available for patients undergoing arthroscopic orthopaedic procedures of the knee, shoulder, and hip. Measures of construct validity, convergent/divergent validity, survey burden, and floor/ceiling effects were evaluated for PROMIS PF-CAT versus legacy PROMs. Results: PROMIS PF-CAT demonstrated excellent or excellent-good correlation with legacy PROMS for physical function and quality of life for patients undergoing arthroscopic interventions of the knee, shoulder, and hip. Compared to legacy PROM instruments, PROMIS PF-CAT demonstrated the lowest overall survey burden and had the lowest overall number of floor or ceiling effects across participants. Conclusion: PROMIS PF-CAT is an accurate, efficient evaluation tool for sports medicine surgical patients. PROMIS PF-CAT strongly correlates with legacy physical function PROMs while having a lower test burden and less incidence of floor and ceiling effects. PROMIS PF-CAT may be an optimal alternative for traditional physical function PROMs in sports medicine patients undergoing arthroscopic procedures. Further studies are required to extend the generalizability of these findings to patients during postoperative timepoints after shoulder and hip interventionsLevel of Evidence: III.

Background: The purpose of the present study is to determine the association between femoral version and traditional pathologic bony factors commonly used to measure and define patellofemoral alignment. Methods: We performed a retrospective review of patients treated for patellofemoral instability (PFI) at a single institution. Patients included underwent magnetic resonance imaging (MRI) of the lower extremity using a rotational protocol prior to medial patellofemoral ligament reconstruction with or without tibial tubercle osteotomy. Those with a history of ipsilateral lower extremity surgery were excluded. Two independent reviewers measured femoral version, tibial tubercle-trochlear groove (TT-TG) distance, tibial tubercle-posterior cruciate ligament (TT-PCL) distance, and tibial torsion (TT). Pearson correlation coefficients were used to describe the relationships between all radiographic measures. Results: A total of 51 knees (43 patients) were included. The average age and body mass index were 23.7 ± 9.33 years and 29.23 ± 8.04 kg/ m2, respectively. The mean femoral version was 15.61 ± 11.57°. The degree of femoral version did not significantly correlate with TT-TG (r=0.103, p=0.474), TT-PCL (-0.086, p=0.550), or TT (r=0.111, p=0.438). Increased TT-TG distance was strongly associated with increased TT-PCL (r=0.470, p=0.001). In females, increased femoral version significantly correlated with increased TT (r=0.381, p=0.029). Conclusion: Neither increased nor decreased amounts of femoral anteversion significantly correlated with TT-TG, TT-PCL, or TT. Therefore, assessment of femoral version should be measured independently of conventional measures when considering osteotomies to correct PFI.Level of Evidence: IV.

BACKGROUND: Arthroscopic shoulder capsulolabral repair using glenoid-based suture anchor fixation provides consistently favorable outcomes for patients with anterior glenohumeral instability. To optimize outcomes, inferior anchor position, especially at the 6-o'clock position, has been emphasized. Proponents of both the beach-chair (BC) and lateral decubitus (LD) positions advocate that this anchor location can be consistently achieved in both positions. HYPOTHESIS: Patient positioning would be associated with the surgeon-reported labral tear length, total number of anchors used, number of anchors in the inferior glenoid, and placement of an anchor at the 6-o'clock position. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: This study was a cross-sectional analysis of a prospective multicenter cohort of patients undergoing primary arthroscopic anterior capsulolabral repair. Patient positioning in the BC versus LD position was determined by the operating surgeon and was not randomized. At the time of operative intervention, surgeon-reported labral tear length, total anchor number, anchor number in the inferior glenoid, and anchor placement at the 6-o'clock position were evaluated between BC and LD cohorts. Descriptive statistics and between-group differences (continuous: t test [normal distributions], Wilcoxon rank sum test [nonnormal distributions], and chi-square test [categorical]) were assessed. RESULTS: In total, 714 patients underwent arthroscopic anterior capsulolabral repair (BC vs LD, 406 [56.9%] vs 308 [43.1%]). The surgeon-reported labral tear length was greater for patients having surgery in the LD position (BC vs LD [mean ± SD], 123.5°± 49° vs 132.3°± 44°; P = .012). The LD position was associated with more anchors placed in the inferior glenoid and more frequent placement of anchors at the 6-o'clock (BC vs LD, 22.4% vs 51.6%; P < .001). The LD position was more frequently associated with utilization of ≥4 total anchors (BC vs LD, 33.5% vs 46.1%; P < .001). CONCLUSION: Surgeons utilizing the LD position for arthroscopic capsulolabral repair in patients with anterior shoulder instability more frequently placed anchors in the inferior glenoid and at the 6-o'clock position. Additionally, surgeon-reported labral tear length was longer when utilizing the LD position. These results suggest that patient positioning may influence the total number of anchors used, the number of anchors used in the inferior glenoid, and the frequency of anchor placement at the 6 o'clock position during arthroscopic capsulolabral repair for anterior shoulder instability. How these findings affect clinical outcomes warrants further study. REGISTRATION: NCT02075775 (ClinicalTrials.gov identifier).

BACKGROUND: This study aimed to (1) compare PROMIS with previously validated legacy instruments and (2) to assess between group differences of PROMIS PF-CAT [Physical Function Computer Adaptive Test] for patients undergoing isolated primary ACL reconstruction [ACLR] vs. primary ACL reconstruction with additional ligamentous intervention [MLIK]. LEVEL OF EVIDENCE: II; Prospective Cohort Study. METHODS: At a single preoperative timepoint, 42 [MLIK] and 73[ACLR] patients completed: Short Form 36 Health Survey (SF-36) Mental (MCS) and Physical Component Summary (PCS), Knee Injury and Osteoarthritis Outcome Score (KOOS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), EuroQol-5 dimensions (EQ-5D) and Marx Knee Scale. Spearman correlation coefficients (non-parametric data) assessed correlations between PROMIS PF-CAT and legacy PROs [Patient-Reported Outcome instruments]. Floor and ceiling effects were assessed using chi-square tests. Between group differences were assessed (Wilcoxon Rank sum test). RESULTS: PROMIS PF-CAT for the MLIK cohort [Table 2] demonstrated an excellent-good correlation with SF-36 Physical Function (PCS; r = 0.64, p < 0.01), EQ-5D (r = 0.68, p < 0.01), and KOOS Quality of Life (QOL) (r = 0.68, p < 0.01); good correlation with KOOS ADL (r = 0.52, p = 0.01), KOOS Sports (r = 0.44, p < 0.01), KOOS Pain (r = 0.44, p < 0.01) and WOMAC Function (r = 0.52,p = 0.01). PROMIS PF-CAT scores differed for ACL vs. MLIK cohorts (41.9 ± 6.6 vs. 37.6 ± 9.0, p < 0.01). PROMIS PF-CAT demonstrated the fewest floor and ceiling effects [Table 4] versus legacy PRO instruments. CONCLUSION: PROMIS PF-CAT demonstrated strong correlations with previously validated PRO instruments and offers a favorable alternative for patients undergoing ACLR with MLIK repair/reconstruction procedures. Preoperative PROMIS PF-CAT scores were greater for patients undergoing primary ACLR versus MLIK intervention.

PURPOSE: To evaluate the prevalence of preoperatively diagnosed psychiatric comorbidities and the impact of these comorbidities on the healthcare costs of ten common orthopaedic sports medicine procedures. METHODS: Patients undergoing 10 common sports medicine procedures from 2007 to 2017q1 were identified using the Humana claims database. These procedures included anterior cruciate ligament reconstruction; posterior cruciate ligament reconstruction; medial collateral ligament repair/reconstruction; Achilles repair/reconstruction; Rotator cuff repair; meniscectomy/meniscus repair; hip arthroscopy; arthroscopic shoulder labral repair; patellofemoral instability procedures; and shoulder instability repair. Patients were stratified by preoperative diagnoses of depression, anxiety, bipolar disorder, or schizophrenia. Cohorts included patients with ≥1 psychiatric comorbidity (psychiatric) versus those without psychiatric comorbidities (no psychiatric). Differences in costs across groups were compared using Mann-Whitney U tests, with significance defined as P < .05. Linear regression analysis was used to assess rates of procedures per year from 2006 to 2016. RESULTS: In total, 226,402 patients (57.7% male) from 2007 to 2017q1 were assessed. The prevalence of ≥1 psychiatric comorbidity within the entire database was 10.31% (reference) versus 21.21% in those patients undergoing the 10 investigated procedures. Patients with psychiatric comorbidity most frequently underwent rotator cuff repair (28%), hip labral repair (26.3%) and meniscectomy/meniscus repair (25.0%%) had ≥1 psychiatric comorbidity. Compared with the no psychiatric cohort, diagnosis of ≥1 psychiatric comorbidity was associated with increased health care costs for all 10 sports medicine procedures ($9678.81 vs $6436.20, P < .0001). CONCLUSIONS: The prevalence of preoperatively diagnosed psychiatric comorbidities among patients undergoing orthopaedic sports medicine procedures is high. The presence of psychiatric comorbidities preoperatively was associated with increased postoperative costs following all investigated orthopaedic sports medicine procedures. LEVEL OF EVIDENCE: Level III; retrospective comparative study.

PURPOSE: To determine trends in arthroscopic-assisted tibial plateau fracture fixation (AATPFF), to evaluate trends in the overall rate of tibial plateau fracture fixation, and to compare postoperative complications between AATPFF and traditional tibial plateau fixation. METHODS: A retrospective review of patients undergoing AATPFF and traditional tibial plateau fixation was conducted using the Humana Inc. administrative database from 2007 to 2016. A 1:1 propensity match was utilized to match patients in the 2 study groups based on age, sex, obesity, diabetes, hypertension, chronic obstructive pulmonary disease, depression or anxiety, and smoking history. Postoperative complications were grouped as minor medical complications, major medical complications, surgical complications, emergency department visits, and reoperation. Linear regression analysis was used to assess trends and Pearson's χ2 test was used to compare postoperative complications with statistical significance defined as P < .05. RESULTS: In total, 522 patients underwent AATPFF and 3920 patients underwent traditional tibial plateau fracture fixation. There was a 4-fold increase in the use of AATPFF over the study period (P = .0173). Similarly, there was an increase in the utilization of traditional tibial plateau fracture fixation, although to a lesser extent (1.33-fold). After propensity matching, the traditional fixation group demonstrated significantly higher rates of minor medical complications (8.2% vs 2.7%, P = .0002), major medical complications (9.9% vs 4.6%, P = .0018), surgical complications (13.2% vs 2.7%, P < .0001), and emergency department visits (21.4% vs 13.5%, P < .0001) within 90 days of surgery compared with the AATPFF group. There was no difference in reoperation rates within 90 days between the 2 groups (2.9% vs 3.6%, P = .85). CONCLUSIONS: The incidence of tibial plateau fracture fixation is increasing, however, use of AATPFF is increasing at a faster rate compared to traditional techniques. Furthermore, the addition of knee arthroscopy to fracture fixation does not increase the risk of complication, reoperation, or emergency department visit within 90 days. LEVEL OF EVIDENCE: III, retrospective matched cohort.
RESUMO
Background: The use of hip arthroscopy (HA) for the management of intra-articular hip pathology has increased greatly, with a 600% increase in utilization from 2006-2010. Studies have demonstrated good to excellent outcomes in patients undergoing hip arthroscopy for treatment of femoroacetabular impingement (FAI) syndrome. However, some patients undergoing primary hip arthroscopy will require revision hip arthroscopy (revision HA) or conversion to total hip arthroplasty (THA). The purpose of the present study was to evaluate the association between hip arthroscopy failure and (1) osteoarthritis, (2) age > 40 years, and (3) psychiatric comorbidities. Methods: The Humana Inc. insurance claims database was used to identify patients undergoing hip arthroscopy between 2007 and 2015, with query by CPT (current procedural terminology code) of more than 25 million deidentified insurance and Medicare beneficiary claims. Following primary hip arthroscopy, patients were longitudinally tracked for subsequent ipsilateral hip arthroscopy (revision HA) or total hip arthroplasty (THA) with a minimum of 1-year clinical follow-up from the primary HA procedure. Hip arthroscopy failure (HA failure) was defined specifically as patients who underwent a revision HA or THA with a minimum of 1-year of clinical follow-up from the primary HA procedure. Variables assessed included presence of pre-existing osteoarthritis, age < 40 years or age > 40 years, and presence of preoperatively diagnosed psychiatric comorbidities including depression or anxiety. The relationships between revision HA, THA, or HA failure and these variables were assessed utilizing univariate and multiple logistic regression analysis. Independent predictors of revision ipsilateral hip arthroscopy and subsequent hip arthroplasty were identified using multiple logistic regression. Results: In total, 785 patients (64.1% female) underwent primary hip arthroscopy. The overall failure rate with a minimum of 1-year clinical follow-up from the index HA procedure was 18%[140/785; 8% (63/785) revision hip arthroscopy, 10% (82/785) THA]. Multivariable logistic regression analysis identified psychiatric comorbidities (Odds Ratio [OR] 2.8, 95% Confidence Interval [CI] 1.2-6.2, p<0.01) as the only independent predictor of hip arthroscopy failure (revision HA or THA). Independent predictors of revision HA included both psychiatric comorbidity (OR 2.8, 95% CI 1.2-6.2, p<0.01) and age < 40 years (OR 2.6, 95% CI 1.4-5.0, p<0.01), while age > 40 years (OR 3.09, 1.47-7.25, p<0.005), smoking (OR 2.05, 95% CI, 1.68-1.88, p=0.02), and osteoarthritis (OR 3.24, 95% CI 1.98-5.43, p<0.001) predicted conversion to THA. Conclusion: The hip arthroscopy failure rate of 18% in the present study is alarmingly high, a figure much higher than reported in previously published series. Patient factors associated with conversion to THA included age > 40 years, smoking, and preexisting osteoarthritis. The presence of psychiatric comorbidities, specifically depression and anxiety, was independently associated with revision HA and overall HA failure.Level of Evidence: III.
