RESUMEN
Isolated lateral-sided knee pain is a unique problem following total knee arthroplasty (TKA). Reported causes include soft tissue impingement against extruded cement, an overhanging tibial tray, remnant osteophytes rubbing against the iliotibial band (ITB), popliteal tendon impingement, fabella syndrome, and synovial tissue impingement in the lateral gutter. In addition, iliotibial band traction syndrome secondary to guided motion Bi-cruciate stabilizing knee arthroplasty has been recognized as a new clinical entity. Initial work up should include ruling out the most common causes of painful TKA including infection, aseptic loosening, and instability. Radiographs and CT scan are utilized to identify potential source of pain. Ultrasound evaluation (with elicited probe tenderness) can increase diagnostic accuracy. Ultrasound guided local anesthetic injections can confirm the source of pain. Anti-inflammatory medications, physical therapy with ITB stretches, and therapeutic local steroid injections are initial treatment modalities. Satisfactory resolution of symptoms may require surgical intervention directed at the specific cause and may avoid the morbidity associated with revision TKA.
RESUMEN
CASE: We present a 63-year-old patient diagnosed with Waldenstrom macroglobulinemia (WM) through histopathology of bone tissue after total knee arthroplasty for routine osteoarthritis. The patient, surgical team, and the pathologist were unaware of this diagnosis before the surgery. CONCLUSION: The cost-effectiveness of routine histopathologic examination of bone cuts and synovial samples after total joint arthroplasty continues to be a source of debate. Our case highlights an example of the utility of histopathology because it led to the early detection of WM, resulting in prompt treatment to improve quality of life.

CASE: A 50-year-old man presented with chronic refractory symptoms of radiating leg pain with muscle cramps because of a retained bullet in the calf after being shot in 1990. Radiographs confirmed the bullet lodged in posterolateral aspect of calf abutting proximal fibula. An intraoperative point-of-care ultrasound aided in accurate localization of bullet, thereby facilitating precise planning of surgical incision and subsequent removal. CONCLUSIONS: Ultrasound can be used as an alternative tool for safe surgical extraction of deep-seated metallic object with minimal tissue dissection, obviating the need for C-arm.

Background Cirrhosis is a growing disease affecting millions of people in the United States annually. Many cirrhosis patients undergo significant procedures and are met with increased risks such as encephalopathy, impaired immune response, ascites, variceal bleeding, renal disease, and increased malnutrition. Many cirrhosis patients need to undergo major surgical procedures such as total knee arthroplasty (TKA); however, perioperative complications following TKA in cirrhosis patients have not been studied. The purpose of this study was to analyze the demographic characteristics and perioperative complications of cirrhosis patients following TKA. Methods Using the National Inpatient Sample (NIS) database, we looked at retrospective data from the years 2016-2019 to analyze the incidence of perioperative complications, length of stay (LOS), and the cost of care (COC) among patients undergoing TKA who were categorized as cirrhosis patients, compared with those who are not. A propensity match was conducted to consider associated comorbidities that influence perioperative complications. Results Of the 558,256 patients analyzed who underwent TKA, 1670 (0.3%) were diagnosed with cirrhosis. After matching, cirrhosis patients had a longer LOS (4.22 vs. 3.68 days, p=0.016) and COC ($90,624 vs. 80676.87, p<0.001) than patients in the control group. Moreover, cirrhosis patients had a higher likelihood of developing acute renal failure (odds ratio (OR): 3.05, 95% CI: 2.07-4.50, p<0.001), blood loss anemia (OR: 1.60, 95% CI: 1.34-1.92, p<0.001), periprosthetic fracture (OR: 3.27, 95% CI: 1.31-8.18, p=0.007), periprosthetic infection (OR: 3.14, 95% CI: 1.99-4.95, p<0.001), and blood transfusions (OR: 1.62, 95% CI: 1.12-2.35, p=0.009) than patients in the control group. Conclusion The cirrhosis group had a significantly higher COC, longer LOS, and higher rates of perioperative complications than non-cirrhosis patients. This data will help providers make informed decisions about patient care and resource allocation for cirrhosis patients undergoing TKA.
RESUMEN
In the era of outpatient shoulder surgery, bundled payment, safe, predictable, and time-efficient pain management strategies for shoulder arthroplasty (SA) are important. Ultrasound-guided interscalene blocks (ISBs), currently the gold standard for postoperative pain management after shoulder surgery, can be highly operator dependent, time-consuming, and not without complications. We developed a new surgical technique of surgeon-administered intraoperative brachial plexus block in patients undergoing SA open shoulder surgery using the deltopectoral approach. This procedure could be performed after the exposure, either at the beginning or end of the bony work. This procedure is simple, safe, and effective. We did not notice any complications that are typically seen with ISB-like respiratory depression secondary to phrenic nerve palsy, rebound pain after the block wore off, and pain related conversion of outpatient SA to inpatient, over the period of four years (2018-2022). This technique has additional advantages over the established "gold standard" ISB in terms of time and cost savings and improved operating room efficiency.
RESUMEN
BACKGROUND: This research adds to the literature by providing prognostic information for physicians and patients regarding the outcomes of operative management of Maisonneuve fractures (MFs). To date, this is the only cohort study of patient-reported outcomes measurement information systems (PROMIS) scores following surgical fixation of MF. Patient outcomes were compared focusing on the mean population with an inter-analysis using basic demographic information, radiographic findings, and patient comorbidities and their respective impact on PROMIS scores. METHODS: A total of 24 patients between 2012 and 2020 met the inclusion criteria and completed PROMIS surveys at a minimum of 18 months postoperatively. Patient charts were reviewed through the electronic medical record (EMR) for demographic information and comorbidities as well as operative variables. PROMIS scores for physical function (PF), pain interference (PI), and depression were obtained via follow-up visits and phone calls. The impact of categorical variables on complications was compared using Chi-Squared tests. Variables were analyzed with a type 3 SS test to stratify independent risk factors' effect on PROMIS scores and to account for confounding variables. RESULTS: PROMIS PF averaged 44.84 and was significantly affected by BMI>30 (p=.033), hypertension (HTN) (p=.026), patients with clinical anxiety or depression (p=.047), and subsequent screw removal (p=.041). PROMIS PI averaged a score of 54.57 and was significantly affected by BMI>30 (p=.0046), coronary artery disease (CAD) (p=.0123), patients with clinical anxiety or depression (p=.0206), and subsequent screw removal (p=.0039). PROMIS depression scores averaged 46.03 and were significantly affected by the presence of CAD (p=.049) and subsequent screw removal (p=.023). CONCLUSION: Patient-reported outcomes following MF surgery demonstrated PROMIS scores within +/- 1 standard deviation of the population-based control, and thus many patients can reasonably expect to return to a level of function comparable to the general population. Nonetheless, the significant effects of patient comorbidities and surgical variables ought to be evaluated and utilized as prognostic indicators when managing patient expectations prior to operative treatment of an MF injury.
RESUMEN
Objectives: The aim of the study is to evaluate the impact of cirrhosis on inpatient hospital complications and healthcare costs in elective Total Hip Arthroplasty (THA). Methods: A 4-year retrospective analysis of the Nation Inpatient Sample (NIS) database, who underwent elective THA stratified by the presence or absence of cirrhosis was performed (2016-19). The records of specific postoperative complications, the cost of care (COC), and the length of stay (LOS) were evaluated by statistical analysis. Results: The NIS database identified 367,894 patients who underwent THA, of which 1,134 (0.3%) were cirrhotic. In the unmatched analysis, patients with cirrhosis showed significantly elevated rates (P< 0.05) of in-hospital complications compared to non-cirrhotic controls, including mortality (0.7% vs. 0.1%), acute renal failure (9.2% vs. 2.5%), blood loss anemia (30.4% vs. 19.5%), pneumonia (1.1% vs. 0.3%), periprosthetic fracture (3% vs. 1.2%), dislocations (2.5% vs. 1.4%), infection (4.2% vs. 1%), wound dehiscence (0.8% vs. 0.1%) and blood transfusion (11.3% vs. 3.5%). After propensity matching, significantly higher rates of blood loss anemia (30.4% vs. 26.7%; P=0.05), periprosthetic dislocations (2.4% vs. 1%; P=0.008), and infections (4.2% vs. 2.7%, P=0.05) were seen in the cirrhotic cohort, while the rate of pulmonary embolism was significantly lower (0% vs. 0.8%, P=0.002), as was myocardial infarction (0.08% vs. 0.7%, P=0.017). Concerning LOS in the hospital, patients with cirrhosis stayed significantly longer in both the unmatched (4.2 vs. 2.3 days; P <0.001) and matched (4.2 vs. 3.68; P=0.016) controls. The average COC was greater in the cirrhotic group, with a mean value of $90,264 vs. $66,806.31 (P<0.001) in the unmatched and $90,624 vs. $80,676.87 (P=0.001) in the matched cohort. Conclusion: Cirrhosis is associated with longer lengths of stay, higher hospital costs, and a greater risk of perioperative in-hospital complications such as blood loss anemia, dislocation, and infection after THA. This data could assist during preoperative patient counseling and improve the strategies for effectively utilizing the finite healthcare resources without compromising patient care and financial compensation from payers.
RESUMEN
Various positioning techniques have been described for the osteosynthesis of olecranon fractures, each with their own pros and cons. The supine position is time-efficient and better suited in a polytrauma setting but frequently requires an assistant to maintain optimal limb positioning. Also, adequate fluoroscopic imaging is not possible without moving the operative extremity outside the sterile field. We describe a simple and reproducible method addressing these limitations while providing excellent surgical access and intraoperative imaging.
RESUMEN
INTRODUCTION: Patients with spinal cord injury (SCI) with degenerative joint disease of the knee may require total knee arthroplasty (TKA). This study examines the demographic and immediate postoperative outcomes of patients with SCI who undergo TKA. METHODS: Admissions data for TKA and SCI were analyzed from the National Inpatient Sample database using International Classification of Diseases, 10th Revision, Clinical Modification diagnosis codes. An extensive array of preoperative and postoperative variables was compared among SCI TKA patients and non-SCI TKA patients. An unmatched and matched analysis using a 1:1 propensity match algorithm was conducted to compare the two groups. RESULTS: Patients with SCI tend to be younger and have a 7.518 times greater risk of acute renal failure, 2.3 times greater risk of blood loss, and higher risk of local complications, including periprosthetic fracture and prosthetic infection. The average length of stay in the SCI cohort was 2.12 times greater, with a 1.58 times higher mean total incurred charge than the non-SCI group. CONCLUSION: SCI is associated with an increased risk of acute renal failure, blood loss anemia, periprosthetic fractures and infections, a longer length of stay, and greater incurred charges in TKA patients. STUDY DESIGN: Retrospective study.

Purpose: To review the clinical studies describing the use of ipsilateral biceps tendon autograft for bridging irreparable massive rotator cuff tears (MRCTs). Methods: A systematic review was conducted of MEDLINE, Embase, Cochrane, CINAHL, and Scopus databases using search terms "massive rotator cuff tear," "irreparable rotator cuff tear," and "long head of the biceps tendon." Only clinical human studies in which the biceps tendon was used as a bridging graft in MRCTs were included. All review studies, technique papers, and studies describing the use of biceps tendon as superior capsular reconstruction equivalent or rotator cable were excluded. Results: A total of 45 studies were initially identified, of which only 6 studies met the inclusion criterion. All studies were retrospective in nature, with a total of 176 patients. All studies reported a clinically significant improvement in postoperative functional outcomes, although this was not compared to a control group in all the studies. Pain was assessed using the visual analog scale (VAS) in 4 studies, and all reported an improvement in postoperative VAS ranging from 5 to 6 points. One study reported an improvement in pain scale from Japanese Orthopedic Association from 13.1 to 22.5 (9 points). One study did not report a VAS score as this study was published before the VAS score was developed. All the reported studies saw improvements in range of motion. Conclusions: The use of the long head of the biceps tendon as an interposition/bridging patch to augment the MRCT repair can reduce the VAS score, improve elevation and external rotation, and improve clinical and functional outcomes. Level of Evidence: IV, systematic review of Level III and IV studies.
RESUMEN
CASE: Phosphodiesterase type-5 enzyme (PDE5) inhibitors are well tolerated and used to treat erectile dysfunction. We report a case of prosthetic knee effusions associated with PDE5 inhibitor use in a 65-year-old man after total knee arthroplasty (TKA). PDE5 inhibitor treatment was stopped, and the patient had no further episodes of painful effusions. CONCLUSION: This report describes a previously unknown adverse effect of PDE5 inhibitor use in a prosthetic joint after TKA. We hope to encourage physicians managing patients after joint replacement to be aware of the association between PDE5 inhibitor use and recurrent joint effusions to improve postoperative outcomes.

Anatomical restoration of volar tilt is a technical challenge in a displaced distal radius fracture with a dorsally angulated fracture pattern accompanied by dorsal metaphyseal comminution. We adopted a reduction technique using a mini-Hohmann retractor, to accomplish the desired volar tilt in a controlled fashion. We would like to present this technical note through a case example describing the technique specifics along with one-year postoperative outcomes.
RESUMEN
BACKGROUND: Patients with Parkinson disease (PD) undergoing total knee arthroplasty (TKA) can present with a unique subset of challenges during their hospital stay. The literature is limited to single-center studies with a small number of patients. This study was aimed to analyze the inpatient complications, length of stay (LOS), and cost of care (COC) associated after TKA with PD over 4 years (2016 to 2019). METHODS: In this retrospective cohort study, we used National Inpatient Sample (NIS) database data from 2016 to 2019 and compared in-hospital complications, LOS, and COC among patients undergoing TKA with and without PD. RESULTS: The National Inpatient Sample database is used to identify 558,371 patients (555,289 without PD and 3,082 with PD) who underwent TKA. After propensity-matching, there was an increased incidence of blood loss anemia (PD group 22.3%, control group 13.5%, P ≤ 0.01), periprosthetic dislocations (1.5% in PD group, 0.4% in control group, P < 0.001), and periprosthetic mechanical complications including but not limited to periprosthetic fractures, knee dislocations, patellar maltracking, and subluxations (1.1% in PD group, 0.6% in control group, P = 0.024) in the PD group. The other in-hospital complications including mortality, acute renal failure, myocardial infarction, pneumonia, pulmonary embolism, deep vein thrombosis, periprosthetic fracture, and wound dehiscence showed no notable differences. The average total incurred charges for the PD group were higher, with a mean of $67,581.58 (SD $44,554.64), than that in the control group, with a mean of $64,795.51 (SD $45,841.25) (P < 0.001). The average LOS was higher in the PD group with a mean of 2.7 days (SD = 1.93) compared with the control group (mean = 2.3, SD = 1.73 days, P < 0.001). CONCLUSIONS: An increased incidence of complications such as acute blood loss anemia, periprosthetic mechanical complications, and increased COC, but no difference in LOS was noted in patients undergoing TKA with PD. This information can be useful to make an informed decision regarding patient care and preferred healthcare setup for TKA in patients with PD.

Purpose: To systematically evaluate the clinical outcomes of superior capsular reconstruction (SCR) using the long head of the biceps tendon for irreparable massive rotator cuff tears. Methods: Multiple electronic databases were searched for studies treating massive and/or irreparable rotator cuff tears with SCR using the biceps tendon while retaining its proximal attachment to the superior glenoid. A PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) flowchart was created. All the included studies were assessed for quality with the Modified Coleman Methodology Score. Multiple variables including patient demographic characteristics, functional scores, visual analog scale (VAS) scores, and complications were extracted and analyzed. Results: Seven studies were included in this review, with a total of 133 patients. The age range of patients was 39 to 82 years, and the duration of follow-up ranged from 6 to 40.7 months. Various validated scoring systems were used for functional outcome evaluation in all studies; all of them showed postoperative improvement greater than the minimal clinically important difference. The VAS score improvement ranged from 3.8 to 7.1. Five studies reported improvement in shoulder forward elevation, with a range of 22° to 95°. Three studies reported retear rates of 21%, 37%, and 66% on postoperative magnetic resonance imaging scans. Two studies reported complications, with the first study reporting revision surgery in 4 of 35 patients and the second study reporting 1 infection and 1 case of deltoid detachment (open procedure) among 17 patients. Conclusions: SCR using the long head of the biceps tendon is a safe and effective procedure. VAS and patient-reported outcome scores showed significant improvement with minimal short-term complications. Level of Evidence: Level IV, systematic review of Level III and IV studies.
RESUMEN
Polyethylene liner dissociation (PLD) is a rare but catastrophic complication following total hip arthroplasty (THA). When it occurs in the early postoperative period, it can be easy to miss the diagnosis. Liner dissociation has been reported previously with the Pinnacle® (DePuy), Harris-Galante® (Zimmer), and Trident® (Stryker) acetabular components. To the best of our knowledge, this is the first case reporting PLD in the G7® cup (Zimmer-Biomet). This case report, along with a review of the literature, highlights the clinical presentation, radiological imaging, treatment options, and technical tips to avoid PLD in the early postoperative period.
RESUMEN
Introduction The surgical treatment of humeral shaft atrophic, gap nonunion following failed surgical fixation is challenging. We intended to evaluate the surgical outcome of failed fixation of humeral shaft atrophic, gap nonunions using locking compression plate (LCP) and autologous nonvascularized fibular graft (ANVFG) and autologous iliac crest bone graft (AICBG). Methods Through our database search between 2015 and 2018, we identified 12 patients with humeral shaft atrophic, gap nonunions with failed surgical fixation underwent open reduction and internal fixation using LCP with autologous fibula graft and iliac crest cancellous bone graft. Results We have followed all twelve patients for a minimum period of 24 months. All patients had radiological and clinical union with a mean time to union of 17 weeks. In one case superficial surgical site infection was noted and successfully treated with intravenous antibiotics, and in another, transient peroneal nerve palsy was identified and resolved in six months. Conclusion LCP with ANVFG and AICBG is a reliable option for "complex" diaphyseal humerus atrophic and gap non unions, especially with significant bone loss. This construct provides mechanical stability and supports biological healing in these complex fractures.
RESUMEN
Iliotibial band traction syndrome (ITBTS) after total knee arthroplasty (TKA) has been well documented following first-generation guided motion bicruciate substituting (BCS) TKA. The incidence of ITBTS following second-generation BCS has been found to be rare, and surgical release of the IT band has not been reported. A 64-year old male was diagnosed with ITBTS following second-generation guided motion BCS TKA. After a three-month trial of non-surgical treatment, he underwent selective open release of the iliotibial band (ITB), which successfully relieved his symptoms. Orthopedic surgeons should keep ITBTS as a possible differential diagnosis when evaluating the lateral-sided knee pain following guided motion BCS TKA.
RESUMEN
An 81-year-old male patient who underwent a Medacta GMK sphere kinematically aligned (KA) total knee arthroplasty (TKA) for end-stage knee osteoarthritis presented with a dislocated medial pivot (MP) tibia polyethylene (PE) insert on routine six-week postoperative x-rays. The patient presented asymptomatic with a normal range of motion. Dissociation of a fixed-bearing (FB) PE implant is an uncommon complication after TKA. There are only a few cases reported in the literature. We report for the first time a case of non-traumatic dissociation of MP PE from the tibial baseplate in a KA TKA in an asymptomatic patient but identified on routine postoperative radiographs.
RESUMEN
Lumbar spinal steroid injections (LSSI) are universally used as preferred diagnostic or therapeutic treatment options before major spinal surgeries. Some recent studies have reported higher risks of surgical-site infection (SSI) for spinal surgeries performed after injections, while others have overlooked such associations. The purpose of this study is to systematically review the literature and perform a meta-analysis to evaluate the associations between preoperative LSSI and postoperative infection following subsequent lumbar decompression and fusion procedures. Three databases, namely PubMed, Scopus, and Cochrane Library, were searched for relevant studies that reported the association of spinal surgery SSI with spinal injections. After the comprehensive sequential screening of the titles, abstracts, and full articles, nine studies were included in a systematic review, and eight studies were included in the meta-analysis. Studies were critically appraised for bias using the validated MINOR (methodological index for non-randomized studies) score. The odds ratio (OR) and 95% confidence interval (CI) were calculated. Subgroup analysis was performed according to the time between LSSI and surgery and the type of lumbar spine surgery. Meta-analysis showed that preoperative LSSI within 30 days of lumbar spine surgery was associated with significantly higher postoperative infection compared with the control group (OR,1.79; 95% CI, 1.08-2.96). Based on subgroup analysis, lumbar spine fusion surgery within 30 days of preoperative LSSI was associated with significantly high-infection rates (OR, 2.67; 95% CI, 2.12-3.35), while no association was found between preoperative LSSI and postoperative infection for lumbar spine decompression surgeries. In summary, given the absence of high-level studies in the literature, careful clinical interpretation of the results should be performed. The overall risk of SSI was slightly higher if the spinal surgery was performed within 30 days after LSSIs. The risk was higher for lumbar fusion cases but not for decompression-only procedures.
RESUMEN
Rerupture after cortical button fixation and whipstitch suture technique is a rare complication of distal biceps tendon repair. The tendon-bone fixation construct can fail for various reasons, including cortical breach, pull out or disengagement of a cortical button, suture breakage, or knot slippage. Occasionally, a cut-through of the tendon substance by the high-tensile strength suture material, called the 'cheese-wire' effect, can happen, especially with premature loading during the early postoperative period. The clinical presentation is more subtle, and the rerupture may go unnoticed. A high index of suspicion and a low threshold for ordering a magnetic resonance imaging (MRI) scan are necessary for a prompt diagnosis and early treatment. We describe the management of a reruptured distal biceps in an active male that happened in the early postoperative period, along with a critical analysis of the failure pattern and potential preventive measures.
