ABSTRACT

BACKGROUND: As healthcare spending continues to rise, price transparency is crucial for patients to calculate a reasonable cost estimate for tests and procedures. Legislative efforts have been successful at mandating increased hospital price transparency, including publishing charge description masters (CDMs), but their usefulness in permitting patients to assess the cost for complex procedures is unclear. We sought to determine CDM and diagnosis-related group (DRG) prevalence and evaluate whether these are effective tools for patients to preemptively ascertain the costs for simple and complex tests and procedures. METHODS: Cross-sectional analysis of publicly available 2019 CDMs and DRGs from 122 hospitals in the United States, including the top-20 as ranked by the US News & World Report Honor Roll and two top-ranked hospitals per state. We first determined the availability of CDMs and DRGs and then determined the ability to estimate the hospital charge for a three-view knee radiograph and a primary total knee arthroplasty (TKA) using CDM and DRG data. RESULTS: One hundred fifteen of 122 (94.3%) hospitals published a CDM, and 78 (63.9%) published a DRG. Top-ranked hospitals published DRGs more frequently than those outside of the Honor Roll designation (P = 0.04). The estimated charge for a three-view knee radiograph could be calculated from 113/115 (98.3%) CDMs. The estimated total charge for a primary TKA could not be obtained from any of the available CDMs. By comparison, the estimated charge for a primary TKA could be obtained from 76/78 (97.4%) of the available DRGs. DISCUSSION: CDMs are available as currently mandated for most hospitals and generally can be used to identify the charges for simple procedures, but they are ineffective tools for patients to estimate the charges associated with a multifaceted healthcare procedure, such as TKA. Although DRGs are less frequently available, they are a more effective resource for patients to estimate charges.

ABSTRACT

BACKGROUND: Debate exists on the optimum fixation construct for large avulsion fractures of the fifth metatarsal base. We compared the biomechanical strength of 2 headless compression screws vs a hook plate for fixation of these fractures. METHODS: Large avulsion fractures were simulated on 10 matched pairs of fresh-frozen cadaveric specimens. Specimens were assigned to receive two 2.5-mm headless compression screws or an anatomic fifth metatarsal hook plate, then cyclically loaded through the plantar fascia and metatarsal base. Specimens underwent 100 cycles at 50%, 75%, and 100% physiological load for a total of 300 cycles. RESULTS: The hook plate group demonstrated a significantly higher number of cycles to failure compared with the screw group (270.7 ± 66.0 [range 100-300] cycles vs 178.6 ± 95.7 [range 24-300] cycles, respectively; P = .039). Seven of 10 hook plate specimens remained intact at the maximum 300 cycles compared with 2 of 10 screw specimens. Nine of 10 plate specimens survived at least 1 cycle at 100% physiologic load compared with 5 of 10 screw specimens. CONCLUSION: A hook plate construct was biomechanically superior to a headless compression screw construct for fixation of large avulsion fractures of the fifth metatarsal base. CLINICAL RELEVANCE: Whether using hook plates or headless compression screws, surgeons should consider protecting patient weight-bearing after fixation of fifth metatarsal base large avulsion fracture until bony union has occurred.

ABSTRACT

Background. Hallux rigidus is a common pathology afflicting the foot, for which various joint salvage techniques have been described with a multitude of different implants. Recently, a synthetic cartilage implant composed of polyvinyl alcohol (PVA) received FDA premarket approval for the treatment of arthritis of the great toe. The purpose of this study was to (1) systematically review the clinical evidence supporting the use of a PVA implant in hallux rigidus and (2) determine the strength of the recommendation that can be made supporting the use of a PVA implant by evaluating the quality of evidence available. Methods. A systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis. Using the terms "cartiva OR polyvinyl alcohol OR synthetic cartilage OR hemiarthroplasty AND hallux rigidus OR great toe arthritis OR first toe arthritis" we searched the PubMed/Medline database. The quality of the included studies was evaluated using the American Academy of Orthopaedic Surgeons Clinical Practice Guideline and Systematic Review Methodology. Results. Seven studies met the inclusion criteria, 6 of these were derived from a single randomized controlled trial. A moderate recommendation can be given for the use of a PVA implant for hallux rigidus based on short-term outcomes. A limited recommendation can be given for the use of a PVA implant for hallux rigidus based on mid-term outcomes. Conclusion. There are limited studies available detailing the outcomes of a PVA implant for hallux rigidus; however, the results that are available demonstrate a high level of evidence.Levels of Evidence: Level I: Systematic review.

ABSTRACT

BACKGROUND: Plantar fasciitis is the most common cause of plantar heel pain. Several recent randomized control trials (RCTs) have been published comparing the use of platelet-rich plasma (PRP) and corticosteroids (CSs) for the treatment of plantar fasciitis. PURPOSE: To perform a systematic review of RCTs to compare whether PRP or CS injections result in decreased pain levels and improved patient outcomes in the treatment of plantar fasciitis. STUDY DESIGN: Systematic review; Level of evidence, 1. METHODS: Medline, EMBASE, and the Cochrane Library were screened according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines to identify RCTs comparing PRP and CS injections for plantar fasciitis. The visual analog scale (VAS) pain scores and the American Orthopaedic Foot and Ankle Society (AOFAS) scores were compared between groups at 1, 1.5, 3, 6, and 12 months, where possible. Statistical analysis was performed using RevMan, and P < .05 was considered to be statistically significant. RESULTS: A total of 9 RCTs were identified comparing 239 patients with PRP with 240 patients with CS injections. At the follow-up time points, including 1-1.5, 3, 6, and 12 months, there were statistically significant differences in VAS scores in favor of PRP (P = .004, P < .00001, P < .00001, and P < .00001, respectively). At 1 and 3 months, there was no difference in AOFAS scores (P = .76 and P = .35, respectively). However, at 6 and 12 months, there was a difference in AOFAS scores in favor of PRP (P < .00001 and P < .00001, respectively). CONCLUSION: In patients with chronic plantar fasciitis, the current clinical evidence suggests that PRP may lead to a greater improvement in pain and functional outcome over CS injections.

ABSTRACT

The Achilles tendon is the largest, and most commonly torn tendon in the body. The Achilles is usually torn at a region of relative hypo-vascularity proximal to its insertion. However, partial thickness tears and other pathologies often occur at its insertion on the calcaneus. Anatomically, the insertion is a confluence of the gastrocnemius and soleus muscles that fuse to form a myotendinous unit on the posterosuperior aspect of the calcaneus. This review aims to reveal the insertional footprint as individual fascicular components attaching to facets of calcaneal tuberosity. Understanding this anatomy is essential for interpreting tear patterns and surgical implications.

ABSTRACT

Background. Hallux rigidus is the most prevalent arthritic condition of the foot. Treatment of end-stage disease traditionally consists of a first metatarsophalangeal joint (MTPJ) arthrodesis; however, the use of a synthetic cartilage implant is becoming more common. With the high prevalence of disease and implementation of new treatment modalities, health care consumers should be aware of the costs associated with management. The purpose of this study was to determine access to the cost and variability in price of first MTPJ arthrodesis and synthetic cartilage implantation. Methods. Forty academic centers were contacted using a standardized patient script. The patient was a 59-year-old female who had failed conservative treatment of hallux rigidus. Each institution was contacted up to 3 times in an attempt to obtain a full bundled operative quote for a first MTPJ arthrodesis and synthetic cartilage implantation. Results. Twenty centers (50%) provided a quote for first MTPJ arthrodesis and 15 centers (38%) provided a quote for synthetic cartilage implantation. Only 14 centers (35%) were able to provide a quote for both procedures. The mean bundled price for MTPJ arthrodesis was $21 767 (range $8417 to $39 265). The mean bundled price for synthetic cartilage implantation was $21 546 (range $4903 to $74 145). There was no statistically significant difference between the bundled price for first MTPJ arthrodesis and synthetic cartilage implantation. Conclusions. There was limited availability of consumer prices for first MTPJ arthrodesis and synthetic implantation, thus impeding health care consumers' decision making. There was a wide range of quotes for both procedures, indicating potential cost savings.Levels of Evidence: IV, basic science.

ABSTRACT

BACKGROUND: Identifying preoperative patient characteristics that correlate with an increased risk of periprosthetic joint infection (PJI) following total ankle replacement (TAR) is of great interest to orthopaedic surgeons, as this may assist with appropriate patient selection. The purpose of this study is to systematically review the literature to identify risk factors that are associated with PJI following TAR. METHODS: Utilizing the terms "(risk factor OR risk OR risks) AND (infection OR infected) AND (ankle replacement OR ankle arthroplasty)" we searched the PubMed/MEDLINE electronic databases. The quality of the included studies was then assessed using the AAOS Clinical Practice Guideline and Systematic Review Methodology. Recommendations were made using the overall strength of evidence. RESULTS: Eight studies met the inclusion criteria. A limited strength of recommendation can be made that the following preoperative patient characteristics correlate with an increased risk of PJI following TAR: inflammatory arthritis, prior ankle surgery, age less than 65 years, body mass index less than 19, peripheral vascular disease, chronic lung disease, hypothyroidism, and low preoperative AOFAS hindfoot scores. There is conflicting evidence in the literature regarding the effect of obesity, tobacco use, diabetes, and duration of surgery. CONCLUSIONS: Several risk factors were identified as having an association with PJI following TAR. These factors may alert surgeons that a higher rate of PJI is possible. However, because of the low level of evidence of reported studies, only a limited strength of recommendation can be ascribed to regard these as risk factors for PJI at this time.

ABSTRACT

BACKGROUND: The ability to complete an operative report is a vital skill for an orthopaedic surgeon. We hypothesized that most programs do not have formal operative report teaching, that resident operative reports at our institution are incomplete, and that a formal teaching program would improve operative reports. METHODS: A survey of residencies in the United States was conducted assessing the state of operative report education. In addition, resident operative reports were collected at our institution both pre and post a formal educational session. Scores were given for each report out of a possible 35 points. RESULTS: Total 54 institutions responded to the survey, of which 83% indicated that they had no formal resident operative report teaching. Within our institution, 100 resident operative dictations were assessed prior to instituting a formal education session, with a mean score of 24.5. The most commonly missed items in the report were preoperative antibiotics, deep venous thrombosis prophylaxis, and tourniquet time. The mean score of 100 resident operative dictations following the educational session improved to 31.8. CONCLUSION: Most residency programs do not conduct formal resident operative report teaching. Formal instruction on how to complete a comprehensive operative report resulted in a significant improvement in their quality.

ABSTRACT

BACKGROUND: Healthcare costs for the surgical management of ankle arthritis continue to rise. Patients are generally unaware of the prices of the services they use. Understanding the costs associated with surgical management of ankle arthritis is an important facet of patient care. The purposes of this study were to (1) determine the access to the surgical cost of total ankle arthroplasty (TAAs) and ankle arthrodesis and (2) the variability of the price between the two procedures. METHODS: Fifty foot and ankle centers (25 academic, 25 private) that perform TAAs and ankle arthrodeses were contacted using a standardized patient script. The described patient was a 63-year-old man who had failed conservative treatment of ankle arthritis. Each institution was contacted up to three times in an attempt to obtain a full-bundled surgical quote for a TAA and an ankle arthrodesis. RESULTS: Twenty-one centers (42%, 14 academic, 7 private) were able to provide a quote for a TAA and an ankle arthrodesis. The mean bundled price for a TAA was $50,332 (SD ± $25,744), with the mean academic and private center quote being $56,529 and $37,937, respectively. The mean bundled price for an ankle arthrodesis was $41,756 (SD ± $26,033), with the mean academic and private center quote being $48,116 and $29,037, respectively. No statistically significant difference was found between the bundled prices for TAA and ankle arthrodesis. DISCUSSION: This study demonstrated limited availability of consumer prices for TAA and ankle arthrodesis. When comparing different institutions for surgical management of ankle arthritis, there was a wide range of quotes for both TAA and ankle arthrodesis. When comparing the choice of surgical management for ankle arthritis, no statistically significant difference was observed in price between TAA and ankle arthrodesis.

ABSTRACT

BACKGROUND: Hypermobility within the first tarsometatarsal (TMT) joint is a predisposing factor for hallux valgus. The purpose of this study was to assess whether the shape and angulation of the first TMT joint are affected by the positioning of the foot in radiographs. METHODS: Ten adult above-knee fresh-frozen cadaveric specimens were placed into a radiolucent apparatus that allowed controlled angulation of each foot at 0, 5, 10, 15, and 20 degrees in dorsiflexion, plantarflexion, inversion, and eversion. For each specimen, the first TMT joint angle (1TMTJA), shape of the distal articular surface of the medial cuneiform (flat or curved), and image quality of the first TMT joint were measured. RESULTS: The mean value for 1TMTJA was 22.9 degrees (95% confidence interval [CI] 21.9-24). Individual anatomical variations of the specimens as well as the different angulations due to foot positioning significantly influenced the 1TMTJA (both P < .001). Joints that were found to have a flat configuration showed significantly increased 1TMTJA on average when compared to the ones with curved articular surface, 25.9 (95% CI 24.4-27.4) and 20.8 degrees (95% CI 19.5-22.0) (P < .001), respectively. Image quality for visualization of the first TMT joint was progressively better for increased angles of dorsiflexion and inversion. CONCLUSION: The shape and angulation of the first TMT joint on radiographic evaluation are affected by the positioning of the foot. CLINICAL RELEVANCE: Clinical usefulness of these radiographic characteristics is limited and should not influence operative planning in patients with possible instability of the first TMT joint.

ABSTRACT

RECOMMENDATION: There is evidence indicating that the following risk factors may predispose a patient to an infection after a total ankle arthroplasty (TAA): inflammatory arthritis, prior ankle surgery, body mass index (BMI) <19, and peripheral vascular disease. Meanwhile, there is conflicting evidence (which may be due to patient selection bias) indicating that the following risk factors may predispose a patient to infection after a TAA: obesity (BMI >30), tobacco use, diabetes, duration of surgery, age <65 years, hypothyroidism, low preoperative American Orthopaedic Foot & Ankle Society (AOFAS) hindfoot score, and chronic lung disease. LEVEL OF EVIDENCE: Limited. DELEGATE VOTE: Agree: 100%, Disagree: 0%, Abstain: 0% (Unanimous, Strongest Consensus).

ABSTRACT

PURPOSE: To review the basic science studies on platelet-rich plasma (PRP) for cartilage and determine whether there has been an improvement in methodology and outcome reporting that would allow for a more meaningful analysis regarding the mechanism of action and efficacy of PRP for cartilage pathology. METHODS: The PubMed/MEDLINE and EMBASE databases were screened in May 2017 with publication dates of January 2011 through May 2017 using the following key words: "platelet-rich plasma OR PRP OR autologous conditioned plasma (ACP) OR ACP AND cartilage OR chondrocytes OR chondrogenesis OR osteoarthritis OR arthritis." Two authors independently performed the search, determined study inclusion, and extracted data. Data extracted included cytology/description of PRP, study design, and results. RESULTS: Twenty-seven studies (11 in vitro, 13 in vivo, 3 in vitro and in vivo) met the inclusion criteria and were included in the study. All of the studies (100%) reported the method by which PRP was prepared. Two studies reported basic cytologic analysis of PRP, including platelet, white blood cell, and red blood cell counts (6.7%). Nine studies reported both platelet count and white blood cell count (30.0%). Twelve studies reported platelet count alone (40.0%). Nine studies (30.0%) made no mention at all as to the composition of the PRP used. PRP was shown to increase cell viability, cell proliferation, cell migration, and differentiation. Several studies demonstrated increased proteoglycan and type II collagen content. PRP decreased inflammation in 75.0% of the in vitro studies reporting data and resulted in improved histologic quality of the cartilage tissue in 75.0% of the in vivo studies reporting data. CONCLUSIONS: Although the number of investigations on PRP for cartilage pathology has more than doubled since 2012, the quality of the literature remains limited by poor methodology and outcome reporting. A majority of basic science studies suggest that PRP has beneficial effects on cartilage pathology; however, the inability to compare across studies owing to a lack of standardization of study methodology, including characterizing the contents of PRP, remains a significant limitation. Future basic science and clinical studies must at a minimum report the contents of PRP to better understand the clinical role of PRP for cartilage pathology. CLINICAL RELEVANCE: Establishing proof of concept for PRP to treat cartilage pathology is important so that high-quality clinical studies with appropriate indications can be performed.

ABSTRACT

Introduction. Obesity is an increasingly common comorbidity that may negatively affect outcomes following orthopaedic surgery. It is valuable to determine whether obese patients are vulnerable for postoperative complications. The purpose of this study was to analyze data from the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) to determine the effect of obesity on surgical treatment of Achilles tendon ruptures. Methods. Patients who underwent a surgical repair of the Achilles tendon were retrospectively identified through the ACS NSQIP. The patients were divided into 2 cohorts (obese and nonobese), then perioperative and postoperative factors were evaluated for association with obesity. Results. A total of 2128 patients were identified, of whom 887 (41.7%) were classified as obese. Obesity correlated with an increased operative time, 60.9 versus 56.1 minutes. The only postoperative complication associated with obesity was wound dehiscence. Logistic regression adjusted for comorbid conditions demonstrated that obesity was not associated with an increased risk of wound dehiscence. Conclusion. A large segment of the patient population undergoing Achilles tendon repair is obese. Obesity was found to have an increased association with wound dehiscence, likely related to comorbid conditions, following Achilles tendon repair. Obesity was not significantly associated with any other complication. Levels of Evidence: III, Retrospective Cohort Study.

ABSTRACT

BACKGROUND: The evidence supporting best practice guidelines in the field of cartilage repair of the ankle is based on both low quality and low levels of evidence. Therefore, an international consensus group of experts was convened to collaboratively advance toward consensus opinions based on the best available evidence on key topics within cartilage repair of the ankle. The purpose of this article is to report the consensus statements on "Osteochondral Allograft" developed at the 2017 International Consensus Meeting on Cartilage Repair of the Ankle. METHODS: Seventy-five international experts in cartilage repair of the ankle representing 25 countries and 1 territory were convened and participated in a process based on the Delphi method of achieving consensus. Questions and statements were drafted within 11 working groups focusing on specific topics within cartilage repair of the ankle, after which a comprehensive literature review was performed and the available evidence for each statement was graded. Discussion and debate occurred in cases where statements were not agreed upon in unanimous fashion within the working groups. A final vote was then held, and the strength of consensus was characterized as follows: consensus, 51% to 74%; strong consensus, 75% to 99%; and unanimous, 100%. RESULTS: A total of 15 statements on osteochondral allograft reached consensus during the 2017 International Consensus Meeting on Cartilage Repair of the Ankle. One achieved unanimous support and 14 reached strong consensus (greater than 75% agreement). All statements reached at least 85% agreement. CONCLUSIONS: This international consensus derived from leaders in the field will assist clinicians with osteochondral allograft as a treatment strategy for osteochondral lesions of the talus.

ABSTRACT

Hallux valgus is a common pathology of the foot and ankle. Surgical correction of the condition has been described as early as 1836. Since then, numerous different surgical techniques have been documented in the literature. One of the explanations as to why there are so many different surgeries for hallux valgus is the variety of etiologies attributed to causing the condition. This article discusses the etiologies associated with hallux valgus and describes a few of the surgeries commonly used to treat the deformity.

ABSTRACT

BACKGROUND: Sural nerve related symptoms following the extensile lateral approach to the calcaneus (ELA) and the sinus tarsi approach (STA) are a known postoperative complication despite awareness of the course the sural nerve. While the main trunk of the sural nerve and its location relative to the approaches have been previously described, the nerve gives rise to lateral calcaneal branches (LCBs) and an anastomotic branch (AB) that may be at risk of injury. The purpose of this study was to describe the course of the sural nerve, its LCBs and the AB in relation to the ELA and STA. METHODS: 17 cadaveric foot specimens were dissected, exposing the sural nerve, the LCBs and the AB. A line representing the ELA and STA incision was then created. It was noted if the line crossed the sural nerve trunk, any of the LCBs, and the AB, and at what distance they were crossed using the distal tip of the fibula as a reference. RESULTS: The sural nerve was identified in all specimens, and the main trunk was noted to cross the path of the ELA in no specimens and the path of the STA in 2 (12%) specimens. At least one LCB of the sural nerve was identified in all specimens. The ELA crossed the path of at least one LCB in 15 specimens (88%). An AB was present in 9 specimens (53%). If an AB was present, this was crossed by the STA in every instance. CONCLUSIONS: The ELA and the STA traverses the path of either the main trunk of the sural nerve, the LCBs, or the AB in the majority of specimens, potentially accounting for the presence of sural nerve postoperative symptoms regardless of the approach used.

ABSTRACT

Introduction Autologous osteochondral transplantation (AOT) is a treatment for osteochondral lesions with known concerns, including histological degradation of the graft and poor cartilage integration. Platelet-rich plasma (PRP) and hyaluronic acid (HA) have been described has having the potential to improve results. The aim of this study was to evaluate the effect of PRP and HA on AOT in a rabbit model. Methods Thirty-six rabbits underwent bilateral knee AOT treated with either the biological adjunct (PRP, n = 12; HA, n = 12; PRP + HA, n = 12) or saline (control). PRP and HA were administered as an intra-articular injection. The rabbits were euthanized at 3, 6, or 12 weeks postoperatively. The graft sections were assessed using the modified International Cartilage Repair Society (ICRS) scoring system. The results from the PRP alone group is from previously published data. Results The mean modified ICRS histological score for the PRP-treated group was higher than its control ( P = 0.002). The mean modified ICRS histological score for the HA-treated group showed no difference compared with its control ( P = 0.142). The mean modified ICRS histological score for the PRP + HA-treated group was higher than its control ( P = 0.006). There was no difference between the mean modified ICRS scores of the PRP- and the PRP + HA-treated grafts ( P = 0.445). Conclusion PRP may decrease graft degradation and improve chondral integration in an animal model. In this model, the addition of HA was not synergistic for the parameters assessed. LEVEL OF EVIDENCE: Basic science, Level V. CLINICAL RELEVANCE: PRP can be used as an adjunct to AOT, which may decrease graft degeneration and improve clinical outcomes. HA may not influence AOT.

ABSTRACT

The syndesmosis is important for ankle stability and load transmission and is commonly injured in association with ankle sprains and fractures. Syndesmotic disruption is associated with between 5 and 10% of ankle sprains and 11-20% of operative ankle fractures. Failure to recognize and appropriately treat syndesmotic disruption can portend poor functional outcomes for patients; therefore, early recognition and appropriate treatment are critical. Syndesmotic injuries are difficult to diagnose, and even when identified and treated, a slightly malreduced syndesmosis can lead to joint destruction and poor functional outcomes.

ABSTRACT

Adult-acquired flatfoot deformity (AAFD) is a known and recognized cause of pain and disability. Loss of PTT function is the most important contributor to AAFD, and its estimated prevalence is thought to be over 3%. This review aims to summarize the current literature and encompass recent advances regarding AAFD.

ABSTRACT

Anterior ankle impingement is a common cause of chronic ankle pain, particularly in athletic populations. Morris and McMurray provided the earliest descriptions of anterior impingement, coining the condition as "athlete's ankle" or "footballer's ankle". The pathology has since been a topic of considerable investigation and has been re-termed "anterior ankle impingement syndrome". Treatment with open surgery has provided good results historically, but at the price of significant complications. Advancements in ankle arthroscopy have decreased the risk of complication drastically and evidence in the literature indicates that anterior arthroscopy is an effective approach to treating osseous and soft tissue impingement. Effective clinical diagnosis and diagnostic imaging are critical for pre-surgical planning. Preoperative detection of anterior osteophytes has been correlated with outcomes. Factors such as joint space narrowing and large osteophytes may also influence outcomes. Therefore, a comprehensive understanding of diagnosis and surgical technique can influence patient outcomes, and patient expectations can be managed around prognostic indicators such as the presence of osteoarthritis. The purpose of this review is to discuss the etiology, clinical presentation, diagnosis, surgical technique, and postoperative rehabilitation of anteromedial and anterolateral anterior ankle impingement syndrome and to evaluate the evidence-based outcomes of arthroscopic management.
