RESUMEN
ABSTRACT: Chondrosarcoma is an aggressive bone tumor typically affecting older adults in the 6th and 7th decade. These tumors often present as painful masses in the pelvis, ribs, and long bones and have certain characteristic features on the imaging leading to the diagnosis. The occurrence of these tumors in the young adult population is a rare condition that is not well described. Often, they may be confused with benign counterparts, enchondroma or osteochondroma, which does not require any treatment and are very common. The aim of this case series was to analyze the patient presentation and radiographic image findings as well as surgical treatment and outcomes of ten young adults with chondrosarcoma over a three-year period. Overall, imaging of these tumors in young adults did not necessarily demonstrate all typical features of chondrosarcomas such as endosteal scalloping, calcifications, lobular growth, and high uptake on whole-body bone scans. One patient in the case series passed away from complications from dedifferentiated chondrosarcoma, and nine patients have recovered with no local recurrence.

Background: The MAKO Robotic-Arm system is a cutting-edge technology which combines both computed tomography (CT) scanning and three-dimensional planning to determine the ideal size and orientation of implants prior to bone resection. It is typically utilized within a general orthopedic setting for joint replacement procedures, such as total joint arthroplasties. However, its use within orthopedic oncology, which contains a much more compromised patient population and more complex surgical treatment, is not well documented within the literature. Question/purposes: To determine the patient outcomes of those who underwent a total hip arthroplasty (THA) or total knee arthroplasty (TKA) at Morristown Medical Center using the MAKO Robotic-Arm System. Particularly, we aspired to delve into the use of the MAKO in an orthopedic oncology setting for patients with a degenerative hip or knee and a history of cancer or other orthopedic tumor, impending pathological fracture, PVNS, chondromatosis, radiation therapy, or other oncological related conditions. Patients and methods: Our institution monitored twenty-five individuals with unique orthopedic oncology conditions that underwent MAKO robotic-assisted total hip and knee arthroplasty. This was performed between 2020 and 2022 at Morristown Medical Center in New Jersey. During this time period, 52% (13/25) of the operations were performed on knees and 48% (12/25) were performed on hips. Data regarding patient demographics, body mass index (BMI), medications, hemoglobin, hematocrit, comorbidities, American Society of Anesthesiologists (ASA) Class, operative data, the length of stay (LOS), readmission rates due to infection or periprosthetic fractures, and complications were collected retrospectively. All confidence intervals were calculated at the 95% confidence level. Results: Postoperatively, the average LOS was 3.2 days, and there were no complications after any of the MAKO-assisted joint arthroplasty procedures. Additionally, there were no readmissions at any of our recorded intervals - 1-30, 1-60, 1-90, and 1 year - however one patient presented to the emergency department after falling 4 days post-operatively. X-ray imaging ultimately revealed no periprosthetic fracture or malalignment of the prosthesis. Conclusions: The utilization of the MAKO Robotic-Arm System for joint arthroplasty procedures (THAs and TKAs) on orthopedic oncology patients yielded exceptional outcomes, with no complications or readmissions directly attributed to the use of this innovative robotic technology. Thus, this newly emerging surgical system holds great promise, potentially revolutionizing the approach for selected orthopedic oncology patients undergoing total joint arthroplasty compared to the traditional manual techniques. It further demonstrates that its use in an orthopedic oncology setting - where the cohort of patients are often compromised, leading to more intricate surgeries with heightened risks - elicits safety and provides optimal outcomes for patients. Nevertheless, its role within the field is evolving, and in the coming years, as it gains further popularity and sees broader application by orthopedic oncology surgeons, its potential will become clearer. To solidify its position, future clinical investigations and prospective research should be conducted to support the preference of the MAKO system over traditional manual techniques. This will help provide the necessary evidence to advocate for its widespread adoption and continued advancements in orthopedic oncology procedures.
RESUMEN
Objectives: To investigate the incidence and severity of knee pain following retrograde intramedullary nailing of femur fractures and to better understand functional outcomes using validated patient-reported outcome measures. Methods: Fifty-three patients with OTA 32 or 33 fractures treated by retrograde nail at a single academic Level 1 trauma center between 2009 and 2020 were retrospectively reviewed. Patients verbally completed the Oxford Knee Score (OKS) and Patient-Reported Outcome Measurement Information System (PROMIS) Short Form 6b, minimum one year postoperatively. Results: Thirty-four (64%) patients reported the presence of pain. Of those reporting pain, 16 (47.1%) reported their pain as mild. Compared to those without pain, patients with knee pain had lower OKS (30.38 +/- 10.65, versus 41.95 +/- 6.87; P <0.001) and higher PROMIS scores (14.65 +/- 6.76 versus 10.95 +/- 7.09; P=0.066). Conclusion: The increasing severity of pain was inversely correlated with functional status as measured by patient-reported measures. At present, the reliability, high union rates, and otherwise low complication rates associated with retrograde femoral nailing justify its continued use. However, knee pain and functional outcomes should remain an integral part of the preoperative discussion with the patient.
RESUMEN
Degenerative arthritis of the first metatarsophalangeal joint, hallux rigidus, is the most common type of arthritis of the foot, affecting nearly 2.5% of the population over the age of 50. Hallux rigidus can be treated surgically with either Cheilectomy or Synthetic cartilage implant (SCI) hemiarthroplasty. The purpose of this study is to compare outcomes from a single institution on the treatment of hallux rigidus using cheilectomy and SCI hemiarthroplasty. Between 2012 and 2020, 49 patients underwent either a SCI (Polyvinyl alcohol hydrogels) hemiarthroplasty or Cheilectomy for the treatment of hallux rigidus. Functional scores were assessed pre and postoperatively using the American Orthopedic Foot and Ankle scoring System (AOFAS) and the Foot and Ankle Outcome Score survey (FAOS). Plantar and Dorsal range of motion was also assessed pre and postoperatively. Outcomes, complications, and any reoperations were recorded for all patients. Mean pre-op AOFAS for Cheilectomy and SCI were 49.6 and 54.8, respectively, compared to 85.3 and 89.7, respectively, after surgery (p value < 0.05). Mean pre-op Dorsal range of motion (ROM) for Cheilectomy and SCI were 24.0 and 26.0 degrees, respectively, compared to 38.0 and 42.6 degrees, respectively, after surgery (p value < 0.05). SCI hemiarthroplasty patients had higher AOFAS and dorsal ROM at the latest follow up (p value < 0.05). Synthetic cartilage implant (SCI) hemiarthroplasty and cheilectomy both offer promising results and remain viable treatment options to decrease pain, improve function, and maintain motion for hallux rigidus. SCI hemiarthroplasty may offer superior range of motion and functional outcomes than cheilectomy for hallux rigidus. LEVEL OF CLINICAL EVIDENCE: 3.

An acute rupture of the Achilles tendon is a traumatic injury that can cause considerable morbidity and reduced function. Nonoperative intervention may put patients at higher risk of rerupture, whereas surgical intervention carries risk of infection, wound complications, and iatrogenic nerve injury. The mini-open Achilles tendon repair technique has been popularized in helping decrease complications. The goal of this study was to examine and compare the functional outcomes and rate of complications in patients treated with a mini-open repair technique versus a traditional open repair for acute Achilles tendon ruptures. A retrospective review was performed of all patients with a complete Achilles tendon rupture that were treated by a single foot and ankle fellowship-trained surgeon. Functional outcome scores were assessed using the American Orthopaedic Foot and Ankle scoring system (AOFAS) and the Achilles Tendon Rupture Score (ATRS). Eighty-one patients with a complete Achilles tendon rupture underwent mini-open repair and 22 patients underwent traditional open repair surgery between 2013 and 2020. The mean follow-up was 38.40 months (range, 12-71). Mean preoperative AOFAS and ATRS improved in the mini-open group from 45.60 and 47.18 respectively, to 90.29 and 87.97 after surgery (p < .05). Mean preoperative AOFAS and ATRS scores for the traditional open repair (n = 22) cohort were 44.02 and 42.27, respectively. Postoperatively, the AOFAS and ATRS scores improved to 85.27 and 86.64 (P value < .05), respectively. There was no statistically significant difference in postoperative ATRS scores. However, the mini-open repair group showed a statistically higher postoperative AOFAS score (90.30) than the traditional open-repair group (85.27) (P value < .05). The overall complication rate for our study was 2.9% (2 mini-open repair and 1 traditional open repair). The complication rate in the mini-open repair group and traditional open repair cohort were 2.4% and 4.5%, respectively (P value > .05). One patient in the mini-open repair cohort (1.2%) reruptured his Achilles tendon 4 months postoperatively. A second patient in the mini-open repair group (1.2%) developed a superficial skin infection and suture irritation. One patient (4.5%) in the traditional open repair group developed a superficial skin infection. There were no sural nerve injuries in our series. The mini-open approach to repair a ruptured Achilles tendon is a viable treatment option to decrease the incidence rate of postoperative complications and rerupture rates while also producing a superior cosmetic result.Level of Evidence: 3 (retrospective cohort study N ≥ 30).

BACKGROUND: Patients should be prescribed medication based on their medical condition, without prejudice because of their race, gender, or primary language. However, previous research has shown that men are prescribed more medication than women, patients who are White are prescribed more medications than patients who are non-White, and English-speaking people are prescribed more medications than non-English-speaking patients. However, it is unclear whether these differences also occur in pediatric orthopaedic populations. QUESTIONS/PURPOSES: We asked: (1) Was the amount of opiates prescribed at discharge associated with patient age, gender, race, or primary language? (2) Did the amount of opiates prescribed to patients at discharge change from 2010 to 2020? METHODS: In a single center, between January 2010 and December 2019, we treated 331 patients younger than 18 years surgically for upper and lower long-bone extremity fractures. Patients were considered eligible if they had a nonpathologic fracture. Femur fractures were not included. Based on these criteria, all patients were eligible. The mean age was 12 ± 4 years. The mean weight was 57 ± 33 kg. Among these patients, 76% (253 of 331) were boys and 24% (78 of 331) were girls. From the hospital discharge records, we recorded the amount of opiates prescribed at the time of discharge as measured by morphine milligram equivalents (MMEs). We examined the association of age, gender, race, primary language, weight, and year of treatment using this measurement. We determined a patient's race retrospectively by information given by their parents at time of admission. We did not attempt to contact patients to obtain more nuanced information about their racial background. These data were obtained from the electronic health record. The Wilcoxon rank sum test, t-test, or chi-square test was used to assess associations depending on the distribution of variables, as appropriate. Because opioids as measured in MMEs is zero-inflated, a two-part model analysis was used to adjust for confounding variables. One component of the model was for the probability of having any opiate prescription and another was for the mean number of opioids received. Findings were considered statistically significant if p values were < 0.05. RESULTS: In total, 57% (189 of 331) of children were prescribed opiates at discharge after surgery for long-bone fractures. Opiate MMEs increased with patient age (r = 0.38; p < 0.01). Boys and girls showed no difference in the amounts of pain medication (adjusted odds ratio [OR] 1.38 [95% confidence interval (CI) 0.80 to 2.39]; p = 0.71; adjusted opioid difference: 0.35 MME [95% CI -51.7 to 52.4]; p = 0.99), nor were there differences between patients who were White and those who were non-White (adjusted OR 0.78 [95% CI 0.49 to 1.23]; p = 0.28; adjusted opioid difference: 21.5 MME [95% CI -19.3 to 62.4]; p = 0.30), or between patients for whom English was there primary language and those for whom English was not their primary language (adjusted OR 1.16 [95% CI 0.52 to 2.57]; p = 0.71; adjusted opioid difference: 22.7 MME [95% CI -55.7 to 101.3]; p = 0.57) when adjusted for age and weight. There was no change in opioid prescription amounts from 2010 to 2020 after adjusting for changes in patient age across years (Spearman r = -0.08; p = 0.16). CONCLUSION: Fairness in opioid prescribing based on race, gender, or primary language is possible. Additional research is needed to determine what factors in our institution led to this result. We suggest that prescribers should apply consistent protocols based on factors such as weight or injury type rather than making individual decisions for each patient. This will lead to fairer opioid prescribing to patients from different race and gender groups. LEVEL OF EVIDENCE: Level III, therapeutic study.
