Osteochondral Lesions of the Ankle and Foot.

Osteochondral lesions (OCLs) in the ankle are more common than OCLs of the foot, but both share a similar imaging appearance. Knowledge of the various imaging modalities, as well as available surgical techniques, is important for radiologists. We discuss radiographs, ultrasonography, computed tomography, single-photon emission computed tomography/computed tomography, and magnetic resonance imaging to evaluate OCLs. In addition, various surgical techniques used to treat OCLs-debridement, retrograde drilling, microfracture, micronized cartilage-augmented microfracture, autografts, and allografts-are described with an emphasis on postoperative appearance following these techniques.

Postoperative Ankle Imaging, 2022.

Postoperative ankle imaging requires knowledge of the underlying surgical techniques, the usefulness of various imaging modalities, as well as an appreciation for the desired clinical outcomes. Surgical procedures discussed in this article are tibiotalar fracture fixation, tibiotalar, subtalar, and tibiotalocalcaneal arthrodesis, total ankle arthroplasty, talar osteochondral lesion repair and grafting, lateral ligamentous repair and reconstruction, and peroneal and Achilles tendon repair and reconstruction. Imaging can play a vital role in determining if the expected outcome has been achieved and identifying complications, with particular emphasis placed on the use of radiographs, computed tomography (including weight-bearing), magnetic resonance imaging, and ultrasonography.

Comparative Accuracy of 1.5T MRI, 3T MRI, and Static Ultrasound in Diagnosis of Small Gaps in Repaired Flexor Tendons: A Cadaveric Study.

PURPOSE: We hypothesized that magnetic resonance imaging (MRI) would more accurately diagnose small gaps (<6 mm) after flexor tendon repair than static ultrasound (US) and that suture artifact would negatively impair accuracy. METHODS: A laceration of the flexor digitorum profundus was created in 160 fresh-frozen cadaveric digits and randomized to either an intact repair (0-mm gap) or repairs using a locked 4-strand suture repair with either 4-0 Prolene, Ethibond, or and gaps of 2, 4,or 6 mm; or no suture in which 2-, 4-, or 6-mm gaps were created without a suture crossing the repair site. We performed 1.5T and 3T MRI and static US studies; gap widths were estimated by radiologists blinded to suture presence and true gap widths. RESULTS: The 1.5 and 3.0T MRI had a lower mean error than US for gap sizes 0 and 2 mm. All 3 modalities performed similarly for 4- and 6-mm gaps. Documentation of imaging artifact worsened error, and odds of seeing artifacts were 1.72 higher with MRI than with US. Suture did not worsen artifact nor impair accuracy for any of the 3 modalities. When no suture was used, all 3 modalities significantly overestimated the true gap. CONCLUSIONS: MRI is most accurate for small gaps less than 4 mm. Although all modalities overestimated gap sizes in specimens with a 0-mm gap (intact tendon repair), mean overestimation (<2 mm) was not clinically relevant. Ultrasound overestimated 2-mm gaps (clinically intact repairs), whereas MRIs did not. We recommend MRI for evaluation of gaps after flexor tendon repair. The 1.5T has slightly better sensitivity and specificity for distinguishing clinically intact (gap < 3 mm) from clinically impaired (gap > 3 mm) repairs than the 3T. CLINICAL RELEVANCE: Accurate diagnosis of intact repairs or small gaps (<3 mm) might prevent unnecessary exploration or allow modification of rehabilitation protocols. Diagnosis of clinically relevant gaps (3-6 mm) may allow for earlier revision surgery before significant tendon retraction and adhesions develop, possibly necessitating a staged reconstruction.

Superior capsule reconstruction for irreparable rotator cuff tears: a systematic review of biomechanical and clinical outcomes by graft type.

BACKGROUND: Superior capsular reconstruction (SCR) has recently been proposed as a surgical solution to the irreparable rotator cuff tear and has gained popularity because of promising early results. Therefore, the purpose of this study is to review the biomechanical and clinical outcomes in shoulders with this condition treated with SCR. METHODS: A systematic review was conducted following PRISMA guidelines using PubMed, EMBASE, and Cochrane databases. Studies were included if they reported biomechanical, radiographic, or clinical outcomes data after undergoing SCR in shoulders with irreparable rotator cuff tears. Studies were broken down into 3 categories: cadaveric biomechanical studies, autograft clinical outcome studies, and allograft clinical outcome studies. Biomechanical, radiographic, patient-reported, and functional outcomes data were recorded for each study. RESULTS: Eight cadaveric biomechanical studies, 5 autograft clinical studies, and 4 allograft clinical studies met inclusion criteria. In biomechanical studies, subacromial contact pressure and superior humeral translation were decreased in most tested scenarios. An increase in American Shoulder and Elbow Surgeons (ASES) scores, forward elevation and external rotation values, and acromiohumeral distance (AHD) were found in all autograft clinical studies reporting. Allograft clinical studies reported increases in ASES scores, forward elevation values, and AHD but decreases in visual analog scale scores in all studies reporting. CONCLUSIONS: SCR is emerging as a viable surgical option to address the irreparable rotator cuff tear. Biomechanical studies suggest that the humeral head-stabilizing effect of SCR appears to translate into improved clinical outcomes. Future research should focus on further defining the indications, limitations, and optimal technique.

Surgeon Personal Protection: An Underappreciated Benefit of Positive-pressure Exhaust Suits.

BACKGROUND: Positive-pressure exhaust suits cost more than standard surgical gowns, and recent evidence suggests that they do not decrease infection risk. As a result, some hospitals and surgeons have abandoned positive-pressure exhaust suits in favor of less expensive alternatives. We propose that in addition to their original purpose of decreasing infection rates, positive-pressure exhaust suits may also improve personal protection for the surgeon and assistants, perhaps justifying their added costs. QUESTIONS/PURPOSES: (1) Do positive-pressure exhaust suits decrease exposure to particulate matter during TKA? (2) What areas covered by gowning systems are at risk of exposure to particulate matter? METHODS: Three surgical gowning systems were tested: (1) surgical gown, face mask, surgical skull cap, protective eyewear; (2) surgical gown, face mask, surgical protective hood, protective eyewear; and (3) positive-pressure exhaust suit. For each procedure, a cadaver knee was injected intraarticularly and intraosseously with a 5-µm fluorescent powder mixed with water (1 g/10 mL). After gowning in the standard sterile fashion, the primary surgeon and two assistants performed two TKAs with each gowning system for a total of six TKAs. After each procedure, three independent observers graded skin exposure of each surgical participant under ultraviolet light using a standardized scale from 0 (no exposure) to 4 (gross exposure). Statistical analysis was performed using Friedman's and Nemenyi tests. The interrater reliability for the independent observers was also calculated. RESULTS: The positive-pressure exhaust suits had less surgeon and assistant exposure compared with other systems (p < 0.001). The median overall exposure grade for each gowning system was 4 for System 1 (range, 3-4), 2.5 for System 2 (range, 2-3), and 0 for System 3 (range, 0-0). In pairwise comparisons between gowning systems, the positive-pressure exhaust suits had less exposure than gowning System 1 (difference of medians: 4, p < 0.001) and gowning System 2 (difference of medians: 2.5, p = 0.038). There was no difference found in exposure between Systems 1 and 2 (difference of medians: 1.5, p = 0.330). When gowning Systems 1 and 2 were removed, particulate matter was found in places that were covered such as the surgeon's beard, lips, inside the nostrils, behind the protective eyewear around the surgeon's eye, and in both eyebrows and eyelashes. CONCLUSIONS: The positive-pressure exhaust suits provided greater personal protection with each procedure than the other two gowning systems. CLINICAL RELEVANCE: With conventional gowns, particulate matter was found in the surgeon's eyelashes, under the face mask around the mouth, and inside the nostrils. Despite recent evidence that certain types of positive-pressure exhaust suits may not decrease infection, there is a clear benefit of surgeon protection from potentially infectious and harmful patient substances. Despite their added costs, hospitals and surgeons should weigh this protective benefit when considering the use of positive-pressure exhaust suits.

Polyethylene dissociation from humeral stem status after reverse total shoulder arthroplasty.

BACKGROUND: Reverse shoulder arthroplasty (RSA) is an important treatment option for 4-part proximal humerus fractures in the elderly and arthrosis of the glenohumeral joint with incompetence of the rotator cuff. Unique complications do occur with use of this type of prosthesis. METHODS: We present 4 cases of polyethylene dissociation after RSA. RESULTS: In a series of 549 patients who underwent RSA, the incidence of polyethylene dissociation was found to be 0.7%. CONCLUSIONS: Polyethylene dissociation is a rare complication after RSA. Surgeons should be aware of this possibility if a closed reduction of an RSA dislocation is not possible.

Decoding the Signals: An Analysis of Preference Signaling in the 2023 Orthopaedic Surgery Residency Match.

Background: While previously used in other specialties, the preference signaling program (PSP) was implemented in the 2022 to 2023 orthopaedic surgery residency application process for the first time. The PSP allowed for 30 signaling tokens to be sent by applicants to programs of their choice to indicate particular interest in a program. It remains unknown how the PSP affects applicants and programs in the orthopaedic surgery residency match. Thus, this study's purpose was to assess the utility of preference signaling within the orthopaedic surgery residency application process in its inaugural year of use. Methods: An anonymous electronic survey was emailed to all orthopaedic surgery residency applicants who applied to the authors' institution during the 2022 to 2023 application cycle. The survey was sent after match lists were submitted and closed before the release of match results. The survey collected information regarding applicant demographics, preference signaling habits, and attitude toward preference signaling. Results: The survey was completed by 101 applicants. Applicants applied to a mean of 90 programs (range: 10-197) and received an average of 12 interview invitations (range: 0-39). Applicants almost uniformly used all 30 signals, with nearly two-thirds signaling their home programs (65%, 49/76), and nearly all applicants sending signals to programs at which they performed away rotations (95.7%, 88/92). Applicants received a mean of 9 invitations from programs they signaled, compared with 2 invitations from programs they did not signal. Applicants were significantly more likely to receive an interview invite at a program they signaled than one they did not (p < 0.01). Overall, 57% of applicants (57/101) found the PSP to be helpful, whereas 28% (28/101) found it to be unhelpful, and 16% (16/101) had a neutral opinion. Conclusions: This study reports that the PSP in the 2022 to 2023 orthopaedic surgery match was an effective method of expressing interest in a program because applicants were significantly more likely to receive interview invites to signaled programs. More than half of respondents felt PSP to be helpful; however, the effect on application numbers is still unclear. Level of Evidence: III.

Large Variation in Listed Chargemaster Price for Total Joint Arthroplasty Among Top Orthopaedic Hospitals in the United States.

BACKGROUND: Chargemasters are lists of all services offered by a hospital and their associated cost. This study analyzes chargemaster data to determine price differences among different hospitals for total joint arthroplasty. METHODS: In May 2020, the chargemaster data for highly rated orthopaedic hospitals were accessed, and the diagnostic-related group (DRG) codes related to primary and revision total joint arthroplasty were analyzed (DRGs 466, 467, 468, 469, and 470). The prices listed for each hospital were averaged, and descriptive statistics were calculated. Furthermore, Medicare reimbursement was collected. A subanalysis was performed to determine relationships between geographic and demographic information. RESULTS: The median price for a major hip or knee joint arthroplasty without complications was $68,016 (range: $39,927 to $195,264). The median price of a revision of hip or knee arthroplasty without complications was $90,966 (range: $58,967 to $247,715). The cost of living in the city in which the hospitals are located was weakly correlated with procedure pricing, whereas the median income had no notable relationship to chargemaster pricing. CONCLUSION: The published cost of DRG codes in arthroplasty is widely variable among the top 20 US orthopaedic hospitals, with little correlation to the cost of living or median income of the area.

Bibliometric Analysis of the Top 50 Most Cited Studies on Achilles Tendon Pathology.

Background: The development of Achilles tendon treatment modalities has been rapid, and it is increasingly difficult for clinicians to stay up to date with the most influential studies in this field. In order to fully understand the current state of the literature regarding Achilles tendon injury, it is invaluable to be familiar with the foundational articles and studies upon which the field is built. Purpose: To objectively determine the 50 most frequently cited studies in Achilles tendon pathology and to conduct a bibliometric analysis. Study Design: Cross-sectional study. Methods: The Clarivate Analytics Web of Knowledge database was used to gather data and metrics of Achilles tendon research. The 50 most cited articles were selected for analysis from an initial 17,244 identified articles. The information extracted for each article included author name, publication year, country of origin, journal name, study type, and level of evidence. Results: For these 50 studies, the total number of citations was calculated to be 13,159, with a mean of 263.2 citations per paper. The most cited article collected 657 citations. The publication dates of the 50 studies included in this analysis spanned 41 years (1972-2013). The largest number of articles were published by Swedish authors (n = 14); however, many other countries were represented, including Canada and Finland (n = 6 articles each). The most prevalent study designs were cohort studies (n = 13) with level 4 evidence studies being the most common (n = 14). Conclusion: Among the 50 most influential articles in Achilles tendon pathology, the study designs most commonly used were cohort studies and review articles. Sweden was the country of origin for the most studies included on this list, which reflects this country's interest and commitment to researching Achilles tendon injuries and treatments.

Design and Implementation of a Leadership Development Program for Early-Stage Investigators: Initial Results.

INTRODUCTION: Leadership skills are essential for a successful career in medical research but are often not formally taught. To address these gaps, we designed a leadership development program for early-stage investigators. METHODS: A 9-month virtual program with monthly 2-hour interactive sessions was designed, covering topics such as Leadership in Research, Mentoring, Building Diverse and Inclusive Teams, Managing Conflict, Influencing without Authority, Grant Administration, and Management. An anonymized survey was sent to participants before and after completion of the program, and the results were compared using the chi-squared test. RESULTS: Over a 2-year period, we selected two cohorts of 41 and 46 participants, respectively. After completion of the program, 92% of survey respondents indicated that the program met their expectations and 74% had made use of skills they learned. Participants enjoyed meeting new people and discussing common challenges. There was an increase in participants' perceived understanding of personal leadership qualities, mentoring, communication, conflict resolution, grant management, and collaboration with industry (P < .05). DISCUSSION: A leadership development program for early-stage investigators led to a significant increase in participants' perceived understanding of personal leadership qualities and competencies. It also offered participants the opportunity to meet other researchers in the institution and discuss common challenges.

Open Achilles Tendon Repair.

Background: An open Achilles tendon repair is performed in patients who have suffered an acute rupture. All patients with this injury should be counseled on their treatment options, which include open operative repair and functional rehabilitation. We prefer the use of an open repair in high-level athletes and those who have delayed presentation. Typically, this injury-and the resulting open repair-are seen in young or middle-aged patients as well as athletes. Operative repair of a ruptured Achilles tendon is associated with a much faster return to activity/sport when compared with nonoperative alternatives. This surgical procedure is especially useful in allowing this patient population to return to their previous activity level and functional capacity as quickly as possible. Description: Open repair of a ruptured Achilles tendon begins with a 6 to 8-cm incision over the posteromedial aspect of the lower leg. Superficial and deep dissections are performed until the 2 ends of the ruptured tendon are identified. Adhesions are debrided to adequately mobilize and define the proximal and distal segments of the tendon. With use of a fiber tape suture, a modified locking Bunnell stitch is utilized to secure both ends. The fiber tape is tied securely, and the repair is reinforced with Vicryl suture (Ethicon). Once the tendon is repaired, the paratenon layer is identified and repaired with a running 0 or 2-0 Vicryl suture. This is an important step to minimize postoperative wound complications. The wound is then closed, and the extremity is splinted in maximum plantar flexion. Alternatives: Alternative treatments include minimally invasive surgical techniques such as percutaneous Achilles tendon repair and nonoperative treatment with functional rehabilitation, which can provide excellent outcomes but can also lead to a slight decrease in explosiveness as the patient returns to sport1,2. Rationale: Nonoperative and operative treatment of Achilles tendon rupture can both result in excellent patient outcomes. Appropriate patient selection is critical. Younger patients hoping to return to more highly competitive athletics should consider operative repair3. Possible differences have been identified in peak torque when comparing operative versus nonoperative treatment, with patients who had undergone operative repair having greater peak torque (i.e., explosiveness)2. Otherwise, findings are similar between treatment options as long as the patients meet the criteria for nonoperative treatment. Expected Outcomes: Overall, the scientific literature demonstrates that the functional outcomes following operative repair are good to excellent. In a study by Hsu et al.4, 88% of patients were able to return to their baseline level of activity by 5 months postoperatively, with a complication rate of 10.6% and no reruptures. In a recent meta-analysis by Meulenkamp et al.5, the authors found that operative repair of Achilles tendon rupture was associated with a reduced risk of rerupture compared with primary immobilization (i.e., conventional cast immobilization with delayed weight-bearing for at least 6 weeks only). However, open surgical repair, minimally invasive repair, and functional rehabilitation all had similar risk of rerupture5. In a review by Ochen et al.6 that analyzed 29 studies with a total of 15,862 patients, operative repair was associated with a significantly lower risk of rerupture compared with nonoperative treatment (2.3% versus 3.9%, respectively). However, operative treatment was also associated with a significantly higher complication rate compared with nonoperative treatment (4.9% versus 1.6%, respectively)6. Finally, in a meta-analysis by Soroceanu et al.7, the authors found that if early range-of-motion protocols and functional rehabilitation were utilized, operative and nonoperative treatment resulted in similar outcomes and equivalent rates of rerupture. Important Tips: To prevent rerupture of an Achilles tendon, remind patients to engage in adequate stretching and warming prior to physical activity.Palpate and locate the tendon defect prior to making the first incision.Immobilize the ankle joint in a splint for 2 weeks postoperatively in maximum plantar flexion.Pitfalls include:○ Poor suture management leading to tangling in the repair.○ Undertensioning or overtensioning of the repair, which can be avoided by sterilely draping out both legs and checking resting tension intraoperatively.○ Failure to close the paratenon, causing scarring of the skin or surrounding tissues, which can be avoided by making a relieving incision on the deep surface of the paratenon.○ Leaving suture knots on the dorsal side of the repair that may aggravate the skin.

The Effect of Patellar Surface Morphology on Subchondral Bone Alignment When Matching Patellar Osteochondral Allografts to the Central Ridge of the Patella.

BACKGROUND: Cartilage transplants in the patellofemoral joint have demonstrated lower success rates than in the femoral condyles. This is likely related to the more complex morphology and biomechanics of the joint. While previous studies have evaluated cartilage surface matching and congruence, little work has been done to study the associated subchondral bone congruency in these grafts. PURPOSE: To determine if differences in patellar morphology play a role in the alignment of the donor patellar osteochondral allograft subchondral bone with the native patellar subchondral bone. STUDY DESIGN: Controlled laboratory study. METHODS: A total of 20 (10 Wiberg I and 10 Wiberg II/III) fresh-frozen human patellae were designated as recipients and size-matched to both a Wiberg I and a Wiberg II/III patellar donor. A 16-mm osteochondral allograft transplant to the central ridge of the patella was performed in random order with each matched donor. Transplanted patellae underwent a nano-computed tomography (nano-CT) scan, were digitally reconstructed, and were superimposed on the initial nano-CT scan of the native recipient patella. MATLAB was used to determine the surface height deviation between the native and donor subchondral bone surfaces. DragonFly 3-dimensional imaging software was used to measure subchondral bone step-off heights at the native-donor interface. Differences between matched and unmatched grafts were compared using a 2-way analysis of variance and the Sidak post hoc test. RESULTS: Subchondral bone surface deviation did not differ between Wiberg matched and unmatched allografts. The step-off height was significantly greater in unmatched (1.38 ± 0.49 mm) compared with matched (1.14 ± 0.52 mm) plugs (P = .015). The lateral quadrant step-off differed between matched (0.89 ± 0.43 mm) and unmatched (1.60 ± 0.78 mm) grafts (P = .007). CONCLUSION: While unmatched Wiberg patellar osteochondral allograft implantation did not result in significantly different subchondral bone surface height deviations, there was a significant difference in the circumferential subchondral bone step-off height in the lateral quadrant. Further investigation using finite element analysis modeling will help determine the role of subchondral bone surface on shear and compression force distributions in these areas. CLINICAL RELEVANCE: Given that subchondral bone stiffness and morphology play a role in cartilage health, subchondral bone congruency may play a role in graft survival. Understanding how this congruency plays a role in cartilage force distribution will help surgeons improve the long-term success of osteochondral allograft transplants.

Prevalence of Cannabinoid (CBD) Use in Orthopaedic Sports Medicine Patients.

Background: Although there is some evidence that cannabinoid (CBD) products may provide a therapeutic effect for musculoskeletal pain, little is known about the usage patterns or their prevalence of use in orthopaedic sports medicine patients. Purpose: To report the prevalence and perceived self-efficacy of CBD products in patients evaluated in an orthopaedic sports medicine clinic. Study Design: Descriptive epidemiology study. Level of evidence, 2. Methods: The study population consisted of new patients who visited an orthopaedic surgery sports medicine clinic at a large academic center for consultation with a surgeon between August 2020 and March 2021. All patients were asked to complete a survey that assessed perceived pain and effectiveness of CBD products and other nonsurgical treatment modalities using the Single Assessment Numeric Evaluation score (range, 0-100) and the Numeric Pain Rating Scale (NRS). Descriptive factors were collected via chart review. Descriptive statistics were used to characterize the data. Results: Overall, 823 patients completed the survey (45.4% female; mean age, 51 years [range, 18-87 years]; mean body mass index, 28.9 [range, 17.2-58.4]). Body areas involved included 285 shoulders, 44 elbows, 76 hips, 276 knees, 58 ankles, and 77 other. Of these patients, 19% (152/823) endorsed the use of CBD products before their initial evaluation. The mean NRS for pain was significantly different between non-CBD users and CBD users (5.6 vs 6.1; P = .029). CBD users were significantly more likely to have tried other nonoperative modalities compared with nonusers, including nonsteroidal anti-inflammatory drugs (79.6% vs 69.8%; P = .032), bracing (44.7% vs 34.6%; P = .024), steroid injections (38.8% vs 21.6%; P < .001), and physical therapy (54% vs 36.1%; P < .001). In addition, 30.9% of CBD utilizers reported marijuana use compared with 2.8% of non-CBD users (P < .001) for management of their pain. Conclusion: In the current study, 19% of patients had used CBD products to manage joint-related issues. Sports medicine providers should be aware of this high incidence of usage and the potential interactions CBD products may have with other treatment modalities. Further studies are needed to assess the effectiveness of CBD as a therapeutic agent and the specific interactions it has with other drugs and other forms of treatment.

Talus Visualization in Ankle Fractures: How Much Are We Really Seeing?

BACKGROUND: Despite appropriate care, a subset of patients with ankle fractures has persistent pain. This condition may be associated with intra-articular pathology, which is present up to 65% of the time. PURPOSE: To quantify how much of the talus is visible through an open approach to a standard supination external rotation bimalleolar ankle fracture as a percentage of the entire weightbearing surface of the talus. STUDY DESIGN: Descriptive laboratory study. METHODS: Standard ankle approaches to lateral and medial malleolar fractures were performed in 4 cadaveric ankles from 2 cadavers. Osteotomies were made to simulate a supination external rotation bimalleolar ankle fracture based on the Lauge-Hansen classification. The visible segments of talar cartilage were removed. The tali were then exhumed, and the entire weightbearing superior portion of the talus was assessed and compared with the amount of cartilage removed by an open approach. The mean of the data points as well as the 95% confidence interval were calculated. RESULTS: Four ankle specimens from 2 cadavers were used for these measurements. The mean surface area of the talus was 14.0 cm2 (95% CI, 13.3-14.7 cm2), while the mean area visible via an open approach was 2.1 cm2 (95% CI, 0.5-3.6 cm2). The mean proportion of the talus visualized via an open approach was 14.8% (95% CI, 3.6-26.1%). CONCLUSION: These findings indicate that the true area of weightbearing talar surface visible during an open exposure may be less than what many surgeons postulate. CLINICAL RELEVANCE: Only a small fracture of the talus is visible via an open approach to the talus during fracture fixation. This could warrant arthroscopic evaluation of these injuries to evaluate and treat osteocondral lesions resulting from ankle fractures.

Publicly Available Pricing Information for Orthopaedic Upper Extremity Procedures in the United States Lacks Transparency and Consistency Between Major Hospitals.

Purpose: The purpose of this study was to assess the price variation of various Medicare severity diagnosis-related group codes for orthopaedic upper extremity procedures for the top 20 orthopaedic hospitals using chargemaster price listings from each hospital. Methods: The top 20 orthopaedic hospitals in the United States were determined by querying the U.S. News and World Report's 2020 orthopaedic hospital ranking. This report ranks orthopaedic hospitals according to 4 major domains: outcomes, structure, process/expert opinion, and patient experience. Chargemaster data for the top 20 orthopaedic hospitals was compiled from their websites. Five DRG codes that represented orthopaedic upper extremity procedures were selected, and the pricing information for each was extracted from hospital chargemasters. The median income and cost-of-living index were also compiled for the county that each hospital is located in so that pricing data could be compared to economic measures through regression analysis. Results: Of the top 20 orthopaedic hospitals, 18 had publicly available pricing information in DRG format on their websites. The DRG code with the highest pricing variability was Hand Injury Procedures (DRG 906; range, $12,832-$253,633). The procedure with the least pricing variability was Hand or Wrist Procedures (DRG 514; range, $24,533-$128,403). Additionally, only the cost of living index was a statistically significant predictor of procedure pricing with a weak correlation. Conclusion: Hospital chargemaster listings are lacking in 2 major areas: true price transparency and standardization/consistency between hospitals. Chargemaster data are often difficult to find, confusing to patients, and inaccurate. Additionally, the price range for a single DRG code can also vary substantially depending on the hospital. It is possible that hospitals located in areas with high costs of living and median incomes would charge higher prices, but these factors were not found to support this hypothesis.

Orthopaedic Shoulder and Elbow Fellowship Directors in the United States Have Substantial Research Output but Lack Diversity.

Purpose: To investigate the characteristics of shoulder and elbow fellowship directors (FDs). Methods: FDs for shoulder and elbow fellowship programs in the United States were identified. Demographic, educational, and professional background data were collected from available curricula vitarum, institutional biographies, and the Scopus database. Data collected included age, sex, race/ethnicity, training locations, graduation years, advanced degrees, current institutional information, and personal research H-index. Results: Thirty current orthopaedic shoulder and elbow FDs were identified. The mean Scopus H-index was 25.5. The mean age of FDs was 52.1 years. In total, 29 FDs (96.7%) were male and 1 (3.3%) was female. In addition, 25 of the 30 (83.3%) were White (83.3%), 4 were Asian, and 1 (3.3%) was Hispanic. Two (6.7%) had a military affiliation. Mean time from fellowship training graduation to FD appointment was 13.5 years. Mean number of years as FD was 6.1 years, whereas the number of years tenure with an FD-affiliated institution was 13.0 years. Mean calendar years for completion of orthopaedic residency training and fellowship training were 1998 and 2000, respectively. The residencies that produced the most future FDs were Hospital of the University of Pennsylvania (n = 2) and University of Nebraska Medical Center/Creighton University Health Foundation (n = 2). The fellowship that produced the most future FDs was Columbia University (n = 6). Moderate correlation was found between age and Scopus H-index (r = 0.48; P = .04) and years as FD and Scopus H-index (r = 0.42; P = .03). Conclusions: Women and minorities are under-represented in leadership positions in shoulder and elbow surgery. Shoulder and elbow FDs have the highest H-index of any subspecialty reported in the orthopaedic literature. Research productivity is an important qualification when considering the characteristics of shoulder and elbow FDs. Clinical Relevance: Fellowship directors can have a profound influence on current and future orthopaedic surgeons. It is important to identify the traits that characterize current fellowship directors to have a better understanding of who we choose as leaders in our field.

Between 2000 and 2020, Reimbursement for Orthopaedic Foot and Ankle Surgery Decreased by 30.

Purpose: To examine and analyze Medicare reimbursement rates from 2000 to 2020 for orthopaedic foot and ankle procedures. Methods: The 20 most used orthopaedic foot and ankle surgical procedures were gathered from the Centers for Medicare & Medicaid Services website using the Medicare Provider Utilization and Payment Data Public Use File 2017. The reimbursement data for each code were gathered from The Physician Fee Schedule Look-Up Tool from Centers for Medicare & Medicaid Services. The reimbursement values were adjusted for inflation to 2020 U.S. dollars using the consumer price index. Results: The average inflation-adjusted reimbursement for included procedures decreased by 30% from 2000 to 2020. The greatest mean decreases were observed for "correction of hallux valgus" (-47%) and "partial excision of foot bone" (-41%). The procedures with the smallest mean decreases were observed in "treatment of "Amputation of toe" (-19%) and "closed treatment of metatarsal fracture" (-7%). Conclusions: From 2000 to 2020, Inflation-adjusted Medicare reimbursement for foot and ankle surgery decreased by 30%. Level of Evidence: IV; economic analysis.

Augmenting Osteochondral Autograft Transplantation and Bone Marrow Aspirate Concentrate with Particulate Cartilage Extracellular Matrix Is Associated With Improved Outcomes.

BACKGROUND: Osteochondral autograft transplant (OAT) is often used to treat large osteochondral lesions of the talus and is generally associated with good outcomes. The addition of adjuncts such as cartilage extracellular matrix with bone marrow aspirate concentrate (ECM-BMAC) may further improve the OAT procedure but have not been thoroughly studied. We hypothesized that the placement of ECM-BMAC around the OAT graft would improve radiographic and patient-reported outcomes following OAT. METHODS: Patients who received OAT, with ECM-BMAC or BMAC alone, were screened and their charts were reviewed. For patients who did receive ECM-BMAC, the mixture was spread around the edges of the OAT plug and into any surrounding areas of cartilage damage. Survey and radiographic data were collected. Average follow-up in both groups was over 2 years. Magnetic resonance imaging scans were scored using the Magnetic Resonance Observation of Cartilage Tissue (MOCART) system. Outcomes were compared statistically between groups. RESULTS: Patients treated with ECM-BMAC (n = 34) demonstrated significantly greater improvement of scores in the FAOS categories Symptoms (17 vs -3; P = .02) and Sports Activities (40 vs 7; P = .02), and the MOCART category Subchondral Lamina (P = .008) compared to those treated with BMAC alone (n = 30). They also experienced significantly lower rates of postoperative cysts (53% vs 18%, P = .04) and edema (94% vs 59%, P = .02). CONCLUSION: The addition of ECM-BMAC to OAT was associated with improved imaging and clinical outcomes compared to OAT with BMAC alone.
