When it comes to access to many things people look for, big cities offer numerous advantages over small towns. This seems to be true for consumer goods and services—and for access to health care, especially “high-tech” procedures. That is one issue that Suchman et al. touch on in their retrospective database study in the September 19, 2018 issue of The Journal.
The study evaluated almost 650,000 patients who underwent one of three meniscal procedures (meniscectomy, meniscal repair, or meniscal allograft transplantation) in New York State from 2003 to 2015. In determining which procedures were performed where, the authors found that meniscectomies and meniscal repairs—the vast majority of the procedures performed—were scattered throughout the state, but that meniscal transplants were performed almost exclusively at urban, academic hospitals. This finding is not surprising, considering the technical complexity of allograft transplantation. However, if a patient who would benefit from a meniscal allograft lived three hours from an urban, academic setting, they would either have to travel to the city to be evaluated, treated, and followed, or settle for a different procedure from a surgeon closer to home. Neither option would be optimal in terms of quality care.
At the same time, this article emphasizes that not every patient needs to go to a large hospital to receive excellent care. While a preponderance of recent data shows an association between hospital and surgeon procedure volume and patient outcomes, those data do not mean that smaller hospitals or “medium volume” surgeons should not perform certain procedures. In fact, medium volume surgeons performed the largest proportion of meniscal procedures evaluated in this study.
The fact is that the “delivery” of health care does not happen via FedEx or UPS. The burden falls on patients to transport themselves to the physician, not vice versa. And until that model drastically changes, access disparities based on geography will likely remain.
However, Suchman et al. also found that the majority of patients who underwent any meniscal procedure had private insurance—and that Medicaid patients had the lowest rates of meniscal surgery. Although disparities arising from socioeconomic/insurance status are also very difficult to address, they would seem to be more remediable than disparities related to geography.

The intended goals of requiring electronic medical record (EMR) systems in all hospitals and clinics were rational and, for the most part, patient-centered. EMRs have prevented large numbers of potentially serious medication errors, served as a secure means of making laboratory and imaging data readily available to surgeons, and have provided an efficient mode of communication among members of health care teams.
Unfortunately, the design of most, if not all, EMR systems is focused on coding and billing, not on the doctor-patient interaction during the all-important face-to-face clinic visit. This has had the unintended consequence of requiring dense, protracted documentation of care interactions that seems to de-emphasize the most important part of the EMR entry: the physician’s thought process and treatment plan.
In the September 19, 2018 edition of The Journal, Scott et al. provide us with a unique cost-and-productivity view into the impact that implementing an EMR had within an outpatient orthopaedic clinic. During the first 6 months after a new EMR was launched, total labor costs increased, driven by attending surgeons and medical assistants spending increased time documenting visits. Although the total per-encounter cost returned to baseline levels after 6 months, more time was spent documenting encounters and less time was spent interacting with patients than before EMR implementation. So, even after a return to normal clinic “productivity” after the 6-month learning period, the price paid for increased time spent documenting on the new EMR was decreased provider-patient “face time.”
In my opinion, it is essential that we work to remedy this deficiency. Personally, I do not use EMR-provided templates for documenting physical exam findings, imaging study results, and treatment plans. Instead, I engage with the patient during the visit and make detailed notes in the EMR after the patient leaves. This probably results in “under-billing” for my services, but I am willing to pay that price to increase the value of the visit for the patient—and for my colleagues who may review my notes.
The study by Scott et al. is a necessary first step in understanding EMR ramifications in orthopaedics, but our community needs more broad-based research to further delve into the full impact of EMRs on patient care, patient satisfaction, and cost. Toward that end, the Orthopaedic Research and Education Foundation (OREF) recently extended until September 28, 2018 the deadline for grant proposals to investigate the impact of EMR regulations on the patient-physician relationship. We must continue to address this apparent problem to improve patient care, which was the goal of EMRs in the first place.

The incidence of patients presenting with proximal thigh and groin pain is increasing along with increased interest in recreational athletic activity. When it is associated with a history of increased physical activity, this pain profile often prompts the ordering of a hip MRI if presenting radiographs are unremarkable. However, surgeons often find it difficult to make accurate prognoses and treatment recommendations when the MRI findings suggest a femoral neck stress fracture.
In the September 5, 2018 issue of The Journal, Steele et al. provide us with helpful hints for determining when to proceed with surgical stabilization of the femoral neck in this clinical scenario. Of the femoral neck stress fracture patients in this study who progressed to a surgical procedure, >85% had an effusion on the initial MRI, compared with only 26% of those whose condition resolved with nonoperative treatment. In statistical terms, those who had a hip effusion had an 8-fold increased risk of progression to surgery compared to those without a hip effusion. Meanwhile, the overall fracture-line percentage on the initial MRI turned out to be a poor metric for predicting progression.
Stabilization of a femoral neck stress fracture with percutaneous implants usually improves pain and predictably prevents displacement of the fracture and the attendant risk of nonunion and osteonecrosis of the femoral head. Further clinical research should help validate the seemingly reliable MRI-based predictor identified by these authors.

The goal of orthopaedic surgery is to help the entire musculoskeletal system function in harmony, but the preponderance of orthopaedic research focuses on the skeletal system instead of muscles and tendons. Bone is the only organ that can heal by regenerating tissue that is usually just as effective as the original structure. Consequently, we have focused on developing systems to hold bone intact as it heals so that postinjury function is maximized. Decades have been spent understanding the critical biologic pathways of bone healing and developing implantable, pharmacologic, and cell-based therapies to optimize it.
However, we sometimes overlook the fact that the skeleton can’t move without muscles. Only a few researchers have devoted their careers to understanding skeletal muscle’s response to injury and approaches to enhance muscle recovery after disuse and injury. In the August 15, 2018 issue of The Journal, Hara et al. report on experiments with the protein periostin in mice. Periostin is involved with the process of muscle fibrosis, during which fibroblasts proliferate in the injured area of the muscle and create “scar tissue” that eventually inhibits muscle function.
In one experiment, the authors found that “knockout” mice without the gene that encodes for periostin had improved recovery in a lacerated gastrocnemius muscle, less fibrosis in the muscle, and a significantly reduced number of infiltrating fibroblasts than “wild” mice with the same induced injury. In a similar experiment, they found reduced muscle fibrosis in injured muscles of mice whose production of periostin was neutralized by an antibody injected into the injured muscle. Although a sharp injury to muscle (the laceration model used in these mouse experiments) is not a common clinical scenario in patients seen by orthopaedists, the Hara et al. study represents a step forward in understanding muscle response to injury.
While these findings need to be replicated and then translated into clinical applications for humans, they shed new light on the importance of preventing periostin-induced fibroblast migration after skeletal muscle injury. This research hints at a potential therapeutic strategy to enhance muscle’s functional recovery, which is the most sought-after outcome for patients.
The clinical sports and orthopaedic communities are in need of approaches to limit scarring and atrophy in the setting of muscle disuse and injury. Any of us who unavoidably injure muscle during surgical approaches to bones and joints or for graft harvests and other procedures should be heartened by these findings. It is my hope that more early-career researchers will focus on the first half of the term “musculoskeletal” to advance therapeutic approaches to problems that impact function to a much more permanent degree than do most bone injuries.

Orthopaedic surgery has been blessed with an explosion of diagnostic and therapeutic technology over the last several decades. Improvements in advanced imaging, minimally invasive surgical techniques, and biomaterials and implant design have resulted in both perceived and objectively measurable patient benefits. In many cases, these benefits have been documented with patient-reported functional outcome data as well as improved clinical outcomes such as range of motion, strength, return to work, and pain relief.
However, some of these technological advances serve as expensive substitutes for many of the basic procedures that are universally available at a fraction of the cost, such as taking a thorough history, performing a complete physical examination, and employing basic and time-tested surgical techniques when indicated. While new minimally invasive techniques and computer-assisted preoperative planning are impressive in many respects, it is important to remember the ultimate goal of any orthopaedic operation: improving the patient’s musculoskeletal function.
In the July 18. 2018 issue of The Journal, Buijze et al. examine results from a multicenter randomized trial that compared patient-reported outcomes after using either 2-dimensional (standard radiographs) or 3-dimensional (CT with computer assistance) planning for corrective osteotomy in patients with a distal radial malunion. Although post-hoc analysis revealed that this study was underpowered, the patient-reported outcomes (as measured by DASH and PRWE) were not significantly different between the two preoperative planning groups.
These findings do not mean that advanced technology does not have a place in preoperative planning, but for me the findings emphasize that the most important factors in any orthopaedic surgery are the surgeon’s judgment, skill, and experience. When a surgeon needs assistance maximizing one of those three variables, more advanced technologies may play a role in improving patient outcome. For example, among less experienced surgeons, I suspect that more detailed preoperative planning for a relatively uncommon procedure would improve patient outcome, but it would probably have little impact on the results of procedures performed by more experienced surgeons.
The authors of this study focus on the true bottom line for any surgical intervention: patient outcome. But the other bottom line must also be considered. With the per-procedure incremental cost of 3-D planning and patient-specific surgical guides for upper-extremity deformity corrections estimated to range between $2,000 and $4,000, we must continue to conduct this type of Level I research. For the days of laying one “advance” on top of another with no attention paid to the cost for individual patients and the overall system are long gone.

It is not often that The Journal of Bone & Joint Surgery publishes an article about data-linkage efforts. To even raise the topic with most readers of The Journal would elicit a yawn and quick dismissal of the abstract without a second thought. With this fact duly noted, the possibility of linking health-system joint-replacement registries with Medicare claims data is a first step in a potentially game-changing approach to achieving the long-term clinical research our specialty needs.
In the June 20, 2018 issue of JBJS, Raman et al. detail their successful linkage of a total ankle arthroplasty (TAA) registry with Medicare data without the use of unique patient identifiers. Among 280 TAA patients over the age of 65, 250 had their registry data linked with their Medicare record with exact matches for date of procedure, date of birth, and sex. Of the linked records, 214 (76.4%) had ≥3 years of postoperative claims data.
Why are these findings so important? The answer is follow-up. Every clinician and/or researcher who has attempted to follow patients beyond the first year after a procedure understands how difficult long-term follow-up is. We live in a mobile society in which informative posttreatment data is easily lost. The younger the patient group, the more difficult it usually is to locate patients as time passes. If patients are doing well, many stop coming to our offices, no matter how strongly we recommend annual follow-ups. Everyone is busy—including retirees—and most have better things to do than drive to their surgeon’s office or even complete a web-based questionnaire. Additionally, some patients care only about their own outcomes; they are not as focused as we are on contributing to the advancement of the profession and improving outcomes at the population level.
By linking patient data from a local health-system registry to nationwide claims data, we can gain a better understanding of long-term patient progress. We can use the patient- and implant-specific data housed in the registry and essentially substitute the information from follow-up visits that did not take place within the registry system with the data contained within the Medicare system, which follows beneficiaries wherever they live.
The marriage of registry and claims data is not perfect, though, because patients who are still working probably have private insurance coverage that is not captured by the Medicare system. (Of course, if universal coverage were to come to pass, that issue would be eliminated.) Furthermore, any time claims data are used, uncertainty about the accuracy of coding must be considered. These real-world limitations notwithstanding, the linkage of registry data with claims data does have great potential for enhancing our ability to analyze—and improve—long-term orthopaedic outcomes.

Few things are more disheartening to an orthopaedic surgeon than taking a patient back into the operating suite to treat a failure of fixation. In part, that’s because we realize that the chances of obtaining stable fixation, especially in elderly patients with poor bone density, are diminished with the second attempt. We are additionally cognizant of the risks (again, most significant in the elderly) to cardiopulmonary function with a second procedure shortly after the initial one.
These concerns have led us historically to instruct patients to limit weight bearing for 4 to 6 weeks after hip-fracture surgery. On the other hand, we have seen evidence in cohort studies to suggest that instructing elderly patients with proximal femur fractures to bear weight “as tolerated” after surgery is safe and does not increase the risk of fixation failure.
In the June 6, 2018 issue of The Journal, Kammerlander et al. demonstrate that 16 cognitively unimpaired elderly patients with a proximal femur fracture were unable to limit postoperative weight bearing to ≤20 kg on their surgically treated limb—despite 5 training sessions with a physiotherapist focused on how to do so. In fact, during gait analysis, 69% of these elderly patients exceeded the specified load by more than twofold, as measured with insole force sensors. This inability to restrict weight bearing is probably related to balance and lower-extremity strength issues in older patients, but it may be challenging for people of any age to estimate and regulate how much weight they are placing on an injured lower limb.
With this and other recent evidence, we should instruct most elderly patients with these injuries to bear weight as comfort allows and prescribe correspondingly active physical therapy. As surgeons, we should focus our efforts on the quality and precision of fracture reduction and placement of surgical implants. This will lead to higher patient, family, and physical-therapist satisfaction and pave the way for a more active postoperative rehabilitation period and better longer-term outcomes.

Lateral epicondylar tendinopathy (“tennis elbow”) that is refractory to the usual interventions of physical therapy/home-directed exercise, ice therapy, corticosteroid injections, and rest is a relatively common but very difficult clinical situation. Patients often become frustrated by the lack of improvement and want something to alleviate the pain and disability. However, the orthopaedic community has been reluctant to recommend surgical intervention except for the most severe cases because the outcomes of this surgery are not as predictable as we would like.
It is within this context that Creuzé et al., in the May 16, 2018 issue of The Journal, present results from a double-blind randomized trial elucidating the impact of low-dose Botulinum toxin injection on this chronic condition. Just over half of the patients treated with the Botulinum toxin injection (n = 29) had a >50% reduction in their initial pain intensity at day 90, and almost 20% felt completely cured. Those results were significantly better than those experienced by the group treated with placebo injections (n = 28).
Kudos to the industry sponsor of this study for supporting the double-blind design, because it removed a significant potential bias that might have otherwise tainted the results. The only fault I can find in the trial is a lack of reporting on the patients’ hand dominance and the magnitude of functional demand on their affected limbs. Before and after treatment, a patient who uses power tools with a dominant and affected limb during a physically demanding job may well have more severe symptoms than a person who works at a computer and whose dominant and affected limb is the “non-mouse” extremity.
It is rare indeed to find a study that blinds the administrator of an orthopaedic intervention, as injections and oral medications are not the most prominent tools in our predominantly surgical armamentarium. The inclusion criteria in the Creuzé et al. study reflected a realistic but difficult patient-enrollment scenario—a minimum of 6 months of symptoms (a mean of almost 19 months) despite previous attempts at all other well-known interventions. The fact that nearly all subjects in both groups had a previous steroid injection into the extensor carpi radialis brevis (ECRB) muscle and continued to experience symptoms confirms the difficulty of these cases and represents what many patients go through in search of an effective treatment.
Furthermore, the fact that only 50% of patients in the intervention group achieved significant pain relief reflects the refractory nature of this condition in many patients. These findings seem to indicate that surgical intervention will remain a necessary component of care for patients with lateral epicondylitis who are not cured by Botulinum toxin injection or other, more common treatment modalities—and that we should pay attention to improving surgical outcomes.

In the 1970s and 80s, the debate regarding management of clubfoot deformity centered around the location of incisions and how aggressive to be with open releases of hindfoot joints. At that time, Prof. Ignacio Ponseti had been working on his conservative method of clubfoot correction for decades, but his technique was relegated to the sidelines and dismissed as being out of the main stream. Yet he persisted in carefully documenting his results, quietly perfecting his methods, and disseminating his technique by teaching other practitioners. Ever so slowly, the pediatric orthopaedic community migrated in his direction as the complications of the other aggressive surgical procedures, including stiff and painful feet, became apparent.
In the May 2, 2018 edition of The Journal, Zionts et al. report medium-term results from their center with Ponseti’s method. This is a very important study because most of the previously published data regarding mid- to long-term outcomes had come from Dr. Ponseti’s medical center.
The authors found that all 101 patients in the study treated with the Ponseti method had fair to good outcomes at a mean follow-up of 6.8 years. Nevertheless, >60% of the parents reported noncompliance with the bracing recommendations; almost 70% of patients had at least one relapse; and 38% of all patients eventually required an anterior tibial tendon transfer. Increased severity of the initial deformity, occurrence of a relapse, and a shorter duration of brace use were all associated with worse outcomes.
Taken as a whole, the results of this study are comparable to those presented by Ponseti and others from his institution. Even though the Zionts et al. investigation was also a single-center study, the findings are important considering the widespread use of his technique and limited “external” data confirming the validity of this method.
Dr. Ponseti created and refined a highly impactful technique that yields good outcomes in patients with a difficult problem. Although it took decades for his methods to be widely accepted, the lesson here is that what wins the day are careful documentation, thoughtful attention to how best to teach a method, and persistence in the face of skepticism.
