Disseminated Coccidioidomycosis of the Knee Joint Requiring Synovectomy and Arthrotomy.

INTRODUCTION: Coccidioidomycosis is a fungal infection endemic to the Southwestern United States, Mexico, and South America. While uncommon, inhalation of spores or direct cutaneous contact can lead to disseminated infection in the immunocompetent, with the involvement of the musculoskeletal and integumentary systems. CASE REPORT: A 49-year-old patient with a history of pulmonary coccidioidomycosis presented with the right knee pain and multiple symptomatic abscesses beneath the suprapatellar and infrapatellar fat pads. Arthrocentesis and culture confirmed the infection, and open synovectomy, arthrotomy, and drainage of the infection were performed without complication. CONCLUSION: Disseminated coccidioidomycosis is an uncommon fungal infection that may involve joints and become refractory to pharmacotherapy. Management may require surgical intervention, along with infectious disease consultation and close follow-up. Patients from endemic regions should be evaluated with a comprehensive history of this disease.

Gravity-Assisted Passive Flexion in Total Knee Arthroplasty Recovery.

This study examined the use of gravity-assisted passive flexion (GAP-FLEX) for perioperative total knee arthroplasty (TKA) recovery. The main questions associated with this technique were: (1) Can GAP-FLEX improve patient recovery of range of motion after TKA? (2) Does GAP-FLEX reduce patient time and effort associated with therapy compared with continuous passive motion (CPM)? (3) Does GAP-FLEX reduce overall episodic care cost? A prospective, randomized multicenter study was conducted. Two senior surgeons used identical surgical approach, prosthesis, and postoperative management protocols. Patients consenting to the study were randomly assigned to either standard of care (CPM) or GAP-FLEX groups. Active flexion range of motion (ROM) was measured via goniometer with a primary endpoint established at 4 weeks after surgery. Secondary endpoints included pain and functional mobility. A total of 27 patients completed the study. Average ROM in the GAP-FLEX sample was 8.4° greater than the CPM sample (P=.009) at study endpoint. The GAP-FLEX patients achieved greater postoperative ROM within 2 days and maintained an improvement over CPM to study endpoint. Eighty-five percent (11 of 13) of GAP-FLEX patients achieved or surpassed their baseline ROM by study endpoint, compared with 50% (7 of 14) of CPM patients. These improvements occurred while requiring 90% less therapy time on device compared with the CPM patients. Patients did not report any statistically different pain levels but did exhibit higher functional mobility at endpoint (P=.026). [Orthopedics. 2020;43(5):e431-e437.].

Loss of Follow-up in Orthopaedic Trauma: Who Is Getting Lost to Follow-up?

OBJECTIVES: Noncompliance with postoperative follow-up visits remains a common problem in orthopaedic trauma. The aim of this study was to identify risk factors for loss of follow-up after orthopaedic trauma. DESIGN: Retrospective review. SETTING: Urban level 1 academic trauma center. PATIENTS: A total of 307 (226 men/81 women) patients undergoing surgical treatment of their orthopaedic injuries were included in this study. The average age was 40.4 ± 17 years. INTERVENTION: All patients were treated surgically for their orthopaedic injuries and were instructed to follow-up in the orthopaedic trauma clinic after hospital discharge. MAIN OUTCOME MEASUREMENTS: Noncompliance with follow-up appointment at 6 months after injury. RESULTS: Over a 6-month postoperative period, a total of 215 patients were noncompliant with at least one of their follow-up appointments between hospital discharge and the 6-month follow-up. A logistic regression showed male gender, uninsured or government insurance, and smoker to be statistically significant risk factors for noncompliance with the 6-month follow-up (P < 0.05). Noncompliance with any follow-up appointment was significantly increased in patients with illicit drug abuse (P = 0.02) as per logistic regression analysis. CONCLUSIONS: Loss of follow-up is a common problem in orthopaedic trauma. Our study suggests different risk factors for noncompliance, including male gender, smoker, lack of commercial health insurance, and illicit drug abuse. Health care providers may consider establishing protocols for facilitating follow-up appointments to patients who are at risk for noncompliance.

Cost comparison of patients with 3-level artificial total lumbar disc replacements versus 360° fusion at 3 contiguous lumbar vertebral levels: an analysis of compassionate use at 1 site of the US investigational device exemption clinical trial.

BACKGROUND: We sought to evaluate the difference between hospital service costs of 2 treatment options for patients diagnosed with 3-level degenerative disc disease (DDD) in the lumbar spine. In this retrospective analysis, itemized billing records of hospital stay for patients with 3-level DDD treated with artificial disc replacement (ADR) were compared with those treated with circumferential fusion (standard of care). METHODS: Sequential 3-level DDD patients treated with either ADR (ProDisc-L; Synthes, West Chester, Pennsylvania) or circumferential fusion during the period from January 2004 to October 2005 were included. Surgeries were performed at the same hospital for all patients. The ADR-treated patients were participating in the investigational device exemption clinical trial as part of the compassionate-use arm. Patients treated with fusion at the same institution during this same time interval were evaluated. Itemized billing records were collected at least 1 year after the index surgery. Costs according to hospital service categories were compared between ADR-treated and fusion-treated patients by use of analysis of variance and multivariate statistical techniques. RESULTS: There were 43 consecutive patients treated for 3-level DDD between January 2004 and October 2005. Of these, 21 underwent 3-level ADR and 22 had a 3-level fusion procedure. There was a mean of 3 fewer hospital days for patients treated with ADR (4.77 ± 1.11 days) than for those treated with fusion (8.00 ± 1.82 days) (P < .0001). The cost of hospital services for ADR-treated patients was 49% less excluding instrumentation costs and 54% less when accounting for instrumentation. The pattern of cost was similar when workers' compensation patients were analyzed separately. CONCLUSIONS: ADR-treated 3-level patients benefited from significantly lower costs from their in-hospital stay compared with those treated by fusion. Hospital service costs were 49% (54% when instrumentation was included in the costs) less for ADR patients than for fusion patients.

Allogeneic transfusion after predonation of blood for elective spine surgery.

UNLABELLED: The literature suggests preoperative autologous blood donation in total joint arthroplasty is associated with increased overall transfusion rates compared with nondonation and is not cost-effective for all patients. We asked whether the amount of intraoperative blood loss and blood replacement differs between autologous donors and nondonors in elective spine surgery and whether the rates of allogeneic blood transfusions differ between the two groups; we then determined the cost of wasted predonated units. We retrospectively reviewed 676 patients who underwent elective lumbar spine surgery and compared relevant data to that in a matched cohort of 51 patients who predonated blood and 51 patients who received only cell-saver blood and underwent instrumented spinal fusion. Patients who predonated blood had similar blood loss as patients who did not predonate, but they had more blood replacement (1391 cc compared with 410 cc). Patients who predonated blood also had a lower preoperative hemoglobin level and wasted a half unit of blood on average. There was no major difference in allogeneic blood transfusion rates between the two groups. Our data suggest for short, instrumented lumbar fusion surgeries in patients with a normal coagulation profile, preoperative blood donation is not beneficial. LEVEL OF EVIDENCE: Level II, therapeutic study.
