Fracture Patterns, Outcomes, and Complications of Terrible Triad Injury in Elderly Patients

AimsThe aim of this study was to describe the fracture patterns of terrible triad elbow injury (TTEI) and to evaluate complications, functional and radiographic outcomes in mid-term follow-up in patients older than 65 years. MethodsA retrospective study of 29 patients, mean follow-up of 48.7±4.6 months (range 65-78). Fractures were classified according to the Mason and Regan-Morrey classifications. All patients were evaluated by the Mayo Elbow Performance Scale (MEPS), Quick-Dash, EQVAS, EQ5D scores, and ROM measurement. ResultsThe mean age was 72.3 years and 79% were women. Mason Type III (72%) and Reagan-Morrey type II (69%) were the most frequent fracture type. All patients were managed with a lateral approach consisting of repair or replacement of the radial head and repair of the lateral ulnar collateral ligament (LUCL); of these patients, 19 underwent re-attachment of the coronoid process or anterior capsule. Mean functional scores were MEPS 90.3±7.5, Quick-DASH 18.4±4.6, EQ5D .89± 0.33, EQ-VAS 86.2 ± 21, and VAS 2.2± 1.5. Mean postoperative flexo-extension arc of elbow motion was 105º (range, 65º-145º). Two patients (7%) required revision surgery. We did not observe any joint instability in the elbow after surgery. ConclusionsPatients over 65 years old with a terrible triad elbow injury (TTEI) are at substantial risk of complex fracture patterns, particularly Mason type III radial head fractures and Regan-Morrey type II coronoid fractures. Complications such as joint stiffness and heterotopic ossification are infrequent, while associated capitellum fractures are not rare and should be considered in the assessment as they can impact elbow stability. Despite these challenges, surgical management generally achieves favorable functional outcomes with low complication and reoperation rates.

Lap-re-Do Keyhole versus Lap-re-Do Sugarbaker techniques in large parastomal hernia repair: a retrospective cohort study.

To review the safety and efficacy of Lap-re-Do technique in the treatment of large parastomal hernia. We retrospectively analyzed the recurrence and complications of 81 patients with large parastomal hernia who underwent Lap-re-Do technique in Huashan Hospital of Fudan University from May 2010 to December 2019. And the patients should be able to complete follow-up. With such criteria, we included 40 Lap-re-Do Keyhole patients and 41 Lap-re-Do Sugarbaker patients. Observation time was defined as time to recurrence, death, or last nonevent visit. In large parastomal hernias, Lap-re-Do had a recurrence rate of 25.9% and complication rate of 16.0%, and reoperation rate of 9.9% during the average follow-up time of 41.1 ± 17.8 months. Recurrence rates were 40% (16/40) after Lap-re-Do Keyhole repair and 12.2% (5/41) after Lap-re-Do Sugarbaker repair. Complication rates were 12.5% after Lap-re-Do keyhole and 19.5% after Lap-re-Do Sugarbaker repair Re-operation rates referred to Lap-re-Do keyhole repair were 15% and Lap-re-Do Sugarbaker repair 4.9% during follow-up.The majority of reoperations were indicated by recurrence. Large parastomal hernias are still difficult to be treated. Lap-re-Do Sugarbaker is recommended as an appropriate procedure to close the hernia ring, removing the lengthy colostomy, and effectively reduce recurrence and complication rates.

A Retrospective Case Series of Single-Screw vs Dual-Screw Fixation for Treatment of Medial Malleolus Fractures.

Medial malleolus fractures (MMFs) are common across the world. Currently, there is a lack of consensus on the number of screws used in fixation of MMF. Our aim was to compare the radiographic outcomes of MMF with patients between fractures that have either undergone single-screw (SS) or dual-screw (DS) fixation. This retrospective study assessed patients who had undergone fixation of their MMF from 2012 to 2022. Analysis of their perioperative radiographs was performed to determine the initial type of injury and then radiographic outcomes of nonunion and malunion. A total of 653 patients suffering bimalleolar fractures were identified across a 10-year period. There were 271 patients (41.50%) in the SS group and 382 in the DS group (58.50%). There was no difference found in the nonunion rate of SS (19.19% [52 of 271]) compared with DS (18.85% [72 of 382]) (P = .931). A statistically significant difference between malunion rates was found between the SS group (11.07% [30 of 271]) compared with the DS group (3.93% [15 of 382]) (P < .001).On multiregression analysis, factors that gained significance for development of nonunion was nonfixation of syndesmosis (P = .039), ankle dislocation on arrival (P < .001), and nonrestoration of fibular length (P < .001). Other factors that showed significance for failure to achieve medial anatomical reduction was nonfixation of syndesmosis (P < .001). Use of an SS rather than DS showed a significant increase in nonanatomical reduction but did not increase nonunion or reoperation rate. Syndesmosis fixation was associated with higher rates of MMF nonunion and malunion; as such, surgeons should have a low index of suspicion of injury and fixation.

Spine to pelvis “T-Construct” using magnetic controlled growing rods in non-walkers neuromuscular early-onset scoliosis: a preliminary study

BackgroundsMagnetic controlled growing rods (MCGRs) have been proven to be effective in controlling early onset neuromuscular scoliosis but no study has evaluated the combination with a sacro-bi-iliac construct. The aim of our study is to report surgical management of early onset non-walkers neuromuscular scoliosis correction using MCGRs associated with a sacro-bi-iliac “T-construct” and its mid-term outcomes. Our hypothesis was that this set-up provided well correction of the pelvic obliquity and that this correction was maintained over time. MethodsA retrospective single-center study was conducted including all consecutive neuromuscular early onset scoliosis who underwent spinopelvic fixation using “T-construct” with two MCGRS. Four millimeters lengthening was performed every 4 months during outpatient clinics sessions. All children had a low-dose biplanar stereoradiography in EOS-Chair at pre/postoperative phase, each outpatient clinic appointment and last follow-up. ResultsEighteen patients were included and 17 analyzed at the last follow-up. The mean age at surgery was 9.5 (range from 5 to 12 years), the mean follow-up was 4,7 years (range from 2.5 to 6.6 years) and 8 patients had a Risser stage above four. The global complication rate was 35% (N = 6/17 patients) including three medical and three mechanical complications related to “T-construct”, while the reoperation rate was 18% (N = 2 patients for wound debridement and one for iterative pelvic fixation). Cobb angle and pelvic obliquity were significantly improved by surgery (mean correction was 33.2 ° (55%) and 11 ° (77%) respectively; p < 0.001). At the last follow-up, we noted a loss of frontal Cobb angle correction (p < 0.01) whereas we did not observe any significant loss of pelvic obliquity (p > 0.9). ConclusionsAlthough the global complication rate was 35% (half of which are mechanical complications), the treatment combining pelvic T-construct and MCGRs provides satisfactory correction of pelvic obliquity correction, good maintenance in the medium term and may be a procedure to consider for the surgical treatment of early onset neuromuscular scoliosis.

The Impact of Race and Ethnicity in Microvascular Head and Neck Reconstruction Postoperative Outcomes: A Nationwide Data Analysis.

Racial and ethnic disparities have been extensively reported across surgical specialties, highlighting existing healthcare inequities. Nevertheless, evidence is lacking regarding their influence on postoperative outcomes after head and neck reconstruction. This study aimed to evaluate the impact of race and ethnicity on postoperative complications in head and neck microvascular reconstruction. The ACS-NSQIP database was used to identify patients who underwent head and neck microvascular reconstruction between 2012 and 2022. Baseline characteristics were compared based on race (White, non-White) and ethnicity (Hispanic, non-Hispanic). Group differences were assessed using t tests and Fisher Exact tests. Multivariable logistic regression models were constructed to evaluate postoperative complications between the groups. A Cochran-Armitage test was conducted to evaluate the significance of trends over time. A total of 11,373 patients met inclusion criteria. Among them, 9,082 participants reported race, and 9,428 reported ethnicity. Multivariable analysis demonstrated that Hispanic patients were more likely to experience 30-day readmission (OR 6.7; 95% CI, 1.17-38.4; P=0.032) and had an average total length of stay of 5.25 days longer (95% CI, 0.84-9.65; P=0.020) compared with non-Hispanic patients. Additional subgroup analyses revealed higher rates of all readmissions among non-White patients, particularly those indicated by malignancy (OR 1.23; 95% CI, 1.1-1.4; P=0.002). No significant differences were found in mortality, reoperation rates, and operative times between racial and ethnic groups. The findings of this study suggest that ethnicity may be a significant risk factor for readmission in head and neck microvascular reconstruction. However, future studies are needed to further clarify the impact of race and ethnicity on longer postoperative outcomes, particularly in head and neck cancer minorities.

Tratamiento quirúrgico de fractura subcapital de cadera no desplazada: Femoral Neck System vs. tornillos canulados. Estudio comparativo

ObjectiveThe objective of this study is to compare the outcomes of using the Femoral Neck System (FNS) (DePuy Synthes®) versus the use of cannulated screws (CS) in the surgical treatment of non-displaced subcapital hip fractures. Materials and methodsA retrospective cohort study was conducted on non-displaced subcapital hip fractures treated with CS or FNS between 2020 and 2023, with a minimum follow-up of one year. A total of 28 patients were included, 14 treated with CS and 14 with FNS. Demographic, radiological, clinical, and functional variables were analyzed. ResultsIn the CS group, 64% were male, with a mean age of 66.5 years (SD 14.9) and an average follow-up of 22 months (range, 12-36 months). In the FNS group, 57% were male, with a median age of 60.8 years (SD 13.78) and an average follow-up of 16 months (range, 12-24 months).Regarding functional outcomes, no significant differences were found between FNS and CS in the Harris scale: 94.21±11.55 for FNS and 96.50±6.9 for CS (p=0.618).The total postoperative complications (FNS/CS) were 7.1% versus 43%, and implant failure with conversion to total hip replacement was 0% versus 43%, both significantly higher in the CS group (p=0.047; p=0.016, respectively). The FNS also presented a lower rate of avascular necrosis (0% versus 11.1%, p=0.391) and nonunion (0% versus 20%, p=0.163), although these differences did not reach statistical significance. ConclusionsAlthough both treatment methods, cannulated screws and the FNS, showed similar short-term functional outcomes in the management of undisplaced subcapital femoral fractures, the FNS demonstrated a significantly lower rate of complications and reoperations. These results suggest that the FNS could be considered a safer and more effective option compared to cannulated screws.

The Impact of Travel Distance on Patient-Reported Outcomes Following Primary Total Hip Arthroplasty

BackgroundTotal hip arthroplasties (THAs) are increasingly being performed at high-volume centers, causing some patients to travel further distances to receive care. Concerns remain that increased travel distance limits follow-up, which may impact outcomes and early return to the hospital. The purpose of this study is to evaluate the impact of travel distance on 90-day patient-reported outcomes (PROs) and 90-day complication rates. MethodsPatients undergoing inpatient primary THA at a single center by one of three surgeons between 2017 and 2021 were retrospectively reviewed. Patients whose local and distant medical records were available were included. Patients who lived ≥ 40 miles from the location or follow-up were labeled as “travelers,” and those < 40 miles were “locals.” Primary outcomes included PROs as measured by Veterans Rand 12 Item Health Survey, Harris Hip Score, and Hip Dysfunction and Osteoarthritis Outcome Score for Joint Replacement. Secondary outcomes included rates of 90-day medical complications, emergency department visits, unplanned readmissions, and reoperations. ResultsA total of 413 patients were analyzed at a mean of 897.1 days (range, 92 to 2,196) including 96 travelers. Travelers averaged 96.1 miles for follow-up (range, 40.1 to 678 miles), and locals averaged 14.1 miles for follow-up (range, 0.3 to 39.8 miles). There were no differences in the percentage of patients achieving minimal clinically important difference in PROs. There was no difference in the rate of 90-day medical complications, 90-day readmissions, and reoperations. Local patients were significantly more likely to have unplanned postoperative emergency department visits (travelers = 0%, locals = 7.4%, P = 0.003). ConclusionsTravelers did not demonstrate any significant differences with respect to rates of achieving minimal clinically important difference in PROs or 90-day complication rates. These data suggest that increased travel distance to treatment centers does not impact outcomes following primary THA.

Complications after Reverse Total Shoulder Arthroplasty in the Korean Population: A Single Center Study of 299 Cases

BackgroundKnowledge regarding differences in the order of frequency of complications after reverse total shoulder arthroplasty (RTSA) between Asian and Western populations is limited. We therefore asked for (1) What is the order of frequency of complications after primary RTSA in the Korean population? (2) What are the rates of complication, reoperation, and revision, and clinical outcomes after index surgery? MethodsWe retrospectively reviewed the 299 consecutive cases who underwent primary RTSA with more than 1 year of follow-up over a period of 12 years. The mean age of the patients was 73.4 years (range, 58-88 years) and the mean follow-up period was 3.8 years (range, 1-11.5 years). Evaluation of the clinical outcomes, complications, and reinterventions was performed at the final follow-up. ResultsThe mean VAS pain score, UCLA score, ASES score, and SSV improved from 6.7, 10.2, 30.7, and 27.7% before RTSA to 1.4, 26.4, 80.5, 77.2% after RTSA, respectively (P < .001). Overall, 45 complications (15.1%) were observed in 44 patients. The order of frequency of complications was as follows: 16 cases of scapular stress fracture (5.4%), 9 intraoperative or postoperative periprosthetic fracture (3.0%), 6 brachial plexus injury (2.0%), 4 instability (1.3%), 2 glenoid loosening (0.7%), 2 glenoid disassembly (0.7%), 2 periprosthetic joint infection (0.7%), 1 glenoid fixation failure (0.3%), 1 humeral stem fixation failure (0.3%), 1 hematoma (0.3%), and 1 complex regional pain syndrome (0.3%). Reintervention was performed in 15 cases (5.0%) including reoperation (8 cases; 2.7%) and revision surgery (7 cases; 2.3%). ConclusionAt a mean follow-up period of 3.8 years, primary RTSA showed satisfactory clinical outcomes with a complication rate of 15.1%, a reoperation rate of 2.7%, and a revision rate of 2.3%. Scapular stress fracture appears to be the most common complication after RTSA in the Korean population.

We Reduced the Incidence of Postoperative Complications in Neonatal Ostomy Patients by Using Simple Devices.

Background: Complications frequently occur after neonatal enterostomy. Enterostomy formation is a common outcome following an emergency neonatal laparotomy. This study investigated whether the incidence of complications after enterostomy could be decreased with a drainage device (composed of foreskin cerclage staple, a condom, and a 0-Mersilk braided nonabsorbable suture) fixed in the proximal ostomy bowel tube to improve proximal enterostomy in newborns. Methods: This study was a retrospective case note review of the incidence of emergency neonatal enterostomy incidence over a 3-year period (2/2016-2/2019) at the authors' center. A single surgeon conducted all surgeries. The incidence of intraoperative and postoperative complications was compared between modified and traditional surgery groups. Results: All 47 surgeries were successfully completed (32 boys and 15 girls; sex ratio: 2.13:1). The mean (±SD) birth weight, gestational period, and daily age were 2.64 ± 0.81 kg 35.62 ± 3.76 weeks and 3.49 ± 5.61 days, respectively. The patients were divided into modified surgery groups (20 cases) and traditional surgery groups (27 cases). The modified surgery group had significantly lower rates of total complications, unplanned reoperations, wound-related complications, and stoma-related complications than the traditional group (p <0.05). Conclusions: The preliminary observations suggested that the simple drainage device was a safe and effective operation device that reduced the risk of stoma-related complications.

Men and women demonstrate comparable rates of failures and reoperations following primary osteochondral allograft transplantation of the knee, but women undergo reoperation sooner.

To compare the differences between men and women who receive primary osteochondral allograft transplantation of the knee with regard to preoperative disease presentation, failures and reoperations. A retrospective review of patients ≥18 years old who underwent primary osteochondral allograft transplantation between 2002 and 2020 by a single surgeon with a minimum of 2-year follow-up was performed. Demographic, preoperative, intraoperative and postoperative data were collected for all included patients. Patients were then assigned to two groups, either male or female, based on their reported sex. Statistical analysis was performed to assess sex-related differences in baseline characteristics, comparative survival analysis for determining survival probabilities, and regression analysis for determining variables associated with subsequent reoperation or failure. Among the 437 patients that were identified, 337 patients (77.1% follow-up, 161 men, 176 women) with a minimum of 2-year follow-up were included in our study. The mean age of included patients was 31.3 ± 9.9 years (range, 18.0-55.9), with a BMI of 26.7 ± 4.4 (range, 19.0-39.0) and a mean follow-up of 5.6 ± 2.6 years (range, 2.0-16.3). Male patients had significantly higher body mass index (BMI) (p ≤ 0.01), were more likely to have lesions on the medial femoral condyle (p = 0.041), and had larger lesions at the medial femoral condyle (p ≤ 0.01) and lateral femoral condyle (p ≤ 0.01). 36.8% of patients experienced subsequent reoperation (59 male, 65 female). Mean time to reoperation was 3.5 ± 2.8 years (range, 0.4-16.3 years) in males and 2.1 ± 1.9 years (range, 0.1-13.5 years) in females. No significant difference was found between the two groups with regard to reoperation rates (n.s.) or survivability free from reoperation (n.s.), but females were found to undergo reoperation sooner (p = 0.028). Sixty-three (18.7%) patients experienced subsequent graft failure (36 male, 27 female). No significant difference was found between the two groups in terms of failure rates, time to failure, survivability free from failure, or mode of failure (n.s. for all). Despite several differences in baseline demographics and intraoperative variables, no significant differences were found between men and women receiving primary osteochondral allograft transplantation of the knee with regard to failure or reoperation, with the exception that women underwent reoperation sooner. Retrospective Comparative Cohort Study. Level III.

Revision Surgery Following Primary Reconstruction for Hand Syndactyly

Web creep and scar contracture are established complications of syndactyly reconstruction; however, few reports characterize risk factors for revision surgery. The purpose of this investigation was to examine the rate and risk factors of reoperation for congenital hand syndactyly. Patients undergoing syndactyly reconstruction from 2007 to 2021 at a single children's hospital were reviewed. Cases with less than 1 year of follow-up were excluded. Demographic, surgical, and outcomes data were recorded by each web space to account for mixed treatments. In total, 514 web spaces in 231 children were reviewed with a mean follow-up of 6.0 years after primary reconstruction; 66 (12.8%) web spaces in 51 (22.1%) children underwent revision. The most common procedures were web space deepening due to web creep (57.9% of cases) and digital scar contracture release (45.6%); these were augmented in a minority (17.5%) of cases by other aesthetic/functional procedures. Revisions occurred at a median of 1.7 years after primary reconstruction. First web spaces (thumb-index finger) were most frequently reoperated (33.3%). On multivariable analysis, first web space involvement, complete syndactyly, and complications after the primary reconstruction significantly increased odds of revision. Age at primary reconstruction was not a significant predictor. Following revision, 10.5% of cases had recurrent web creep, and 14.0% had recurrent scar contracture. Eight (1.6%) web spaces in seven (3.0%) children required multiple revisions. Approximately 13% of syndactyly reconstructions (22% of patients) require reoperation. Most revisions occur within 4 years of primary reconstruction. Complete syndactyly, complications after the primary reconstruction, and first web space involvement increase the risk of revision; age at primary reconstruction is not a risk factor. Revision outcomes mirror the index procedure, with 10% to 14% of revised web spaces experiencing recurrent web creep or contracture. Therapeutic IV.

Distal femur fractures in elderly treated with internal fixation or distal femoral replacement - retrospective cohort study on 75 patients assessing functional outcomes, reoperations, and mortality.

This cohort study aimed to describe the functional outcomes, complications, and mortality of patients over 65 with acute distal femur fractures treated with open reduction and internal fixation (ORIF) or distal femoral replacement (DFR). We retrospectively analyzed all patients older than 65, operated consecutively for a distal femur fracture treated with ORIF or DFR. We included 75 patients (9 33A, 5 33B, and 61 33C AO/OTA fractures), 55 treated with ORIF, and 20 with DFR. We used Parker's mobility index (PMI) to assess functional outcomes at 1, 3, and 12months and study closure. We analyzed complications, reoperations, and mortality at 30days, one year, and at the end of the study. The PMI was significantly higher in the DFR group at months 1 (p = 0.023) and 3 (p = 0.032). We found no significant differences between cohorts at one year and the end of follow-up. Postoperative complications were significantly more frequent in the ORIF group (38.10% vs. 10%, p = 0.022). Reoperations were similar in both cohorts (p = 0.98). Mortality at one month was 4% and 20% at one year, and at the end of follow-up, there were no significant differences between groups. The outcomes of this study suggest that DFR offers a faster functional recovery with lower complication rates than those treated with ORIF. Additionally, both options have similar reoperation and mortality rates. Appropriately designed studies are needed to define the best treatment strategy for this type of patient.

Convective Water Vapor Energy Ablation (Rezum®) Versus Prostatic Urethral Lift (Urolift®): A 2-Year Prospective Study.

Introduction: To compare the clinical outcomes and complication rates of convective water vapor energy ablation (Rezum®) and prostatic urethral lift (Urolift®). To identify predictive factors for treatment failures in both treatments. Materials & Methods: Prospective clinico-epidemiological data of patients who underwent Urolift® or Rezum® in a single institution for benign prostatic hyperplasia (BPH) was collected. The choice of intervention depended on the preference of the patients after patient-centric discussions. Results: From October 2019 to October 2022, 86 patients underwent Rezum®, and 62 patients underwent Urolift®. Rezum® involved a longer indwelling catheter duration (12.38 ± 5.548 vs 1.39 ± 3.010 days, p < 0.001) compared with Urolift®. Rezum® was associated with more complications compared with Urolift® (36 [41.9%] vs 10 [16.1%] cases, p < 0.001). Rezum® had more cases of hematuria (17 [19.8%] vs 4 [6.5%] cases [p = 0.022]) and urinary tract infections (27 [31.4%] vs 3 [4.8%] cases, p < 0.001) compared with Urolift®. There were no significant differences in Clavien-Dindo Grade 3-5 complications between the interventions. Urolift® was associated with higher reoperation rates (5 [8.1%] vs 0 [0%] cases, p = 0.010) compared Rezum®. Rezum® had higher anticholinergic usage rates compared with Urolift® post-operation (22 [25.6%] vs 8 [12.9%] cases, p = 0.024). Both interventions showed improvement in the International Prostate Symptom Score (IPSS), quality of life score, and peak velocity flow over the 2 years with no significant difference between the two. Based on receiver operating characteristic curve, preoperation IPSS ≥16 had 95.7% sensitivity and 38.4% specificity to predict the probability of treatment failures after the interventions. Conclusions: There was no difference in clinical outcomes of patients who underwent Rezum® and Urolift®. However, patients who had undergone Rezum® faced more minor complications and more required anti-cholinergic medications. Lastly, physicians should note that patients with IPSS ≥16 would unlikely benefit from either intervention.

Unintended readmissions and reoperations within 30 and 90 days following adult spinal deformity surgery.

This study investigated the rates and etiologies of unintended readmissions and reoperations within 30 and 90 days after adult spinal deformity (ASD) surgery. The authors aimed to identify the risk factors for readmission and reoperation by analyzing patient demographic and surgical characteristics. This retrospective cohort study included 307 consecutive patients who underwent surgery for ASD from 2012 to 2022 at a single academic institution. Data were collected on patient demographic characteristics, comorbidities, operative details, and postoperative complications. Chi-square and multivariable logistic regression models were used to identify the risk factors associated with 30- and 90-day readmissions and reoperations. The mean ± SD age at surgery was 66.6 ± 10.5 years, and the majority (80.8%) of patients were female. The 30-day and 90-day readmission rates were 11.7% and 15.3%, respectively. Multivariable regression for 30-day readmissions revealed that length of hospital stay (LOS) after index surgery of > 20 days (OR 2.48) and surgical factors such as vertebral column resection (VCR) (OR 4.26) and pelvic fixation (OR 4.38) were risk factors. Other factors such as the American Society of Anesthesiologists Physical Status Classification System (ASA) class, prior spine surgery, and age were not associated with 30-day readmissions. Ninety-day readmission was associated with high ASA class (OR 2.37) and LOS > 20 days (OR 2.82). The 30- and 90-day reoperation rates were 7.8% and 10.1%, respectively. The variables associated with 30-day reoperations were intraoperative VCR (OR 3.34) and LOS > 20 days (OR 9.38). Ninety-day reoperations were associated with dural tears (OR 3.33) and LOS > 20 days (OR 3.68). This study provides valuable insights into the incidence of unintended readmission and reoperation within 30 and 90 days after ASD surgery in an Asian population. By identifying the associated risk factors, healthcare providers can customize surgical strategies and optimize perioperative care to effectively mitigate these events.

Evaluation of healing after arthroscopic repair of lateral meniscal tears around the popliteal hiatus

BackgroundThe popliteal hiatus stabilizes the lateral meniscus (LM). Variable failure rates for LM repairs have been reported in knees with lateral meniscal tears (LMTs), which may be attributable to low vascularity around the popliteal hiatus. An effective repair method is essential to enhance the biological healing and stability of LMTs around the popliteal hiatus. HypothesisArthroscopic repair of LMTs, including the popliteus tendon around the popliteal hiatus, is expected to produce a low reoperation rate and effective treatment, both clinically and radiographically. Material and methodsFrom June 2011 to August 2020, 93 patients (mean age 27.9 ± 13.5 years) who underwent arthroscopic repair of LMTs including the popliteus tendon around the popliteal hiatus were enrolled. Patients with LMTs were divided into three groups: isolated LMTs, discoid LMTs, and LMTs with ACL injury. Patients had a minimum clinical follow-up of 2 years (mean 37.9 ± 19.3 months) and Tegner activity, Lysholm knee, and Hospital for Special Surgery (HSS) scores were evaluated for all patients. The widths of the popliteal hiatus and LM extrusion were measured on the sagittal and coronal planes using preoperative and postoperative magnetic resonance imaging (MRI). ResultsThe Tegner activity (2.6 ± 1.2–4.5 ± 1.3), Lysholm (67.9 ± 14.2–88.1 ± 6.4), and HSS scores (79.8 ± 11.5–93.7 ± 5.1) were significantly improved in all knees (p < 0.001). The width of the popliteal hiatus measured on MRI was significantly decreased, when comparing the preoperative and postoperative MRI for all knees (sagittal plane, 2.9 ± 1.4–1.5 ± 0.5 mm; coronal plane, 3.8 ± 2.5 to 1.9 ± 1.0 mm) (p < 0.05). The LM extrusion measured on the sagittal plane of postoperative MRI was also significantly reduced after arthroscopic repair (24.8 ± 3.1–23.7 ± 2.8 mm) (p = 0.001). Five reoperations (5/93, 5.3%) were performed, suggesting a clinical failure. ConclusionArthroscopic repair of isolated, discoid and post-traumatic LMTs including the popliteus tendon around the popliteal hiatus, is an effective surgical treatment for LM stabilization.

Microfracture for medium size to large knee chondral defects has limited long-term efficacy: A systematic review.

To evaluate clinical and radiographic outcomes, return to sport, failure rate, operations and complications in patients undergoing microfracture of the knee, including the femoral condyle, tibial plateau, patella and trochlea, at a mean 10-year or greater follow-up. A literature search was performed by querying SCOPUS, PubMed, Medline and the Cochrane Central Register for Controlled Trials from database inception through May 2023 according to the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Inclusion criteria were level I-IV human studies reporting on outcomes, reoperations and complications following microfracture of the knee at a mean 10-year or greater follow-up. Biomechanical and epidemiological studies, including patients undergoing concomitant realignment procedures, and studies with patients under 18 years old were excluded. Data regarding failure, as defined by each study, as well as reoperations were gathered. Study quality was assessed via the Methodological Index for Nonrandomized Studies criteria. Nine studies from 2003 to 2018, consisting of 727 patients (mean age 38.9 ± 8.1 years; range 25.8-47.6) undergoing microfracture for chondral defects in the knee were identified. Mean follow-up ranged from 10 to 17 years. Males composed 56.5% of patients, with a mean defect size ranging from 2.3 to 4.01 cm2. Based on radiographs at follow-up, osteoarthritis progression occurred in 40%-48% of patients. Magnetic Resonance Observation of Cartilage Repair Tissue scores were low. Patient-reported outcome measures showed significant improvement in postoperative scores at final follow-up. Return-to-sport rate ranged from 17.2% to 20%. Longitudinal analysis revealed declining clinical outcomes and return-to-sport rates from short- and mid- to long-term follow-up. There was high variability in failure definition and reoperations, with 2.9%-41% of patients requiring total knee arthroplasty. At a mean 10-year or greater follow-up, microfracture for chondral defects of the knee 2-4 cm2 in size demonstrated a high rate of osteoarthritis progression with poor healing of the chondral defect and low overall return-to-sport rates. Failure and reoperation rates ranged from 2.9% to 41%, with declining outcomes from short- and mid- to long-term follow-up. The advantages of microfracture relating to availability, complexity, and cost should be weighed against concerns about long-term success, particularly with medium-size and larger lesions. Level IV systematic review.

Nissen sleeve gastrectomy: 5-year follow-up results

BackgroundNissen sleeve gastrectomy is a new bariatric procedurebased on the combination of two well-known surgical techniques (vertical sleeve gastrectomy and Nissen fundoplication). It was conceived as a means of preventing the major drawback of the sleeve gastrectomy (SG), the gastroesophageal reflux disease (GERD), while preserving the advantages of SG in terms of weight loss and remission of obesity-related comorbidities. ObjectivesThe objectives of this study are to present the long-term (5 years) follow-up results on weight loss, evolution of GERD and other comorbidities and the complication rate of the Nissen sleeve gastrectomy. SettingMontpellier University Hospital, France. MethodsThis is a prospective analysis of patients who underwent Nissen sleeve gastrectomy as a first-line bariatric procedure between January 2018 and February 2019. A subgroup analysis of patients with no further surgery during follow-up was also performed. ResultsA total of 144 patients underwent a Nissen sleeve gastrectomy: After adjusting for exclusion criteria, 133 patients comprised the initial study population, 81.9% of whom had complete follow-up for weight and GERD clinical symptom outcomes at 5 years. The mean total weight loss (TWL%) was 22 (± 12.3)% and the mean excess weight loss percentage (EWL%) was 59.4% (± 34.2)%. Of the 63 patients with preoperative clinical symptoms of GERD, we observed an 85.5% 5-year clinical remission rate; however only 25 patients had a gastroscopy at 5 years. The cumulative short- and long-term reoperation rate was 8.1% and the mortality rate was zero. ConclusionsThe Nissen sleeve gastrectomy achieves a satisfactory long-term TWL% and a significant improvement in comorbidities, particularly regarding the incidence of GERD. The rate of complications requiring surgical reoperation is low.

Preoperative Anxiety: An Important Risk Factor of Postoperative Adverse Events and Increased Reoperation Rates in Patients Undergoing Single-Level Anterior Cervical Diskectomy and Fusion

Introduction: With the rising prevalence of mental health disorders, it is important to consider their correlation with surgical outcomes. Anxiety has been associated with adverse events after many surgical procedures, but its relationship relative to anterior cervical diskectomy and fusion (ACDF) regarding medical complications has not previously been assessed in a large database study. Methods: The 2010-Q3 2022 PearlDiver Mariner161 database was used to identify patients undergoing single-level ACDF. Those with versus without preoperative anxiety were matched 1:1 based on age, sex, and Elixhauser Comorbidity Index. Rates of 90-day adverse events were compared by multivariate regression analyses, and 5-year cervical revision surgery rates were compared. Results: Of 287,278 ACDF patients, preoperative anxiety was identified for 36.73%. After matching, patients with anxiety had greater odds ratios of all assessed individual 90-day adverse outcomes, as well as any (OR: 3.09), severe (OR: 2.07), and minor (OR: 3.39) adverse events (P &lt; 0.0001 for all). Those with preoperative anxiety had slightly greater 5-year rates of subsequent cervical spine surgery than those without (P &lt; 0.0001, at 5 years 12.9% versus 11.7%). Discussion: ACDF patients with a history of anxiety had higher odds of many 90-day adverse outcomes and slightly higher 5-year revision surgery rates. These findings may inform patient counseling and risk management strategies.

Addressing meniscal deficiency part 1: An umbrella review of systematic reviews and meta‐analyses on meniscal allograft transplantation

AbstractPurposeMeniscal injuries are common in the young and active population. There is increasing utilization of surgical interventions like meniscal allograft transplantation (MAT) to restore the protective function of menisci following injury leading to meniscal deficiency. Extensive research and publications exist on the management of meniscal injury and the sequalae of meniscal deficiency. However, a comprehensive synthesis of the existing evidence through an umbrella review is lacking. This study aims to fill this gap by providing a current examination of the literature on MAT.MethodsA comprehensive search was conducted in the MEDLINE, Embase and Scopus databases to identify relevant systematic reviews and meta‐analyses. Studies were screened based on predefined inclusion and exclusion criteria. The quality of the included studies was assessed using the AMSTAR‐2 tool.ResultsA total of 41 studies were included in the review, with most published within the last decade. The majority of studies (56.1%) received a ‘Critically Low’ confidence rating, 26.8% were rated as ‘Low’, and only 14.6% were rated as ‘High’ confidence. From the included studies, 51.2% reported on PROMs, with the Lysholm score being the most common. Transplant failure and reoperation rate were reported in 34.1% and 19.5% of studies respectively. Studies on MAT reported favourable short‐term outcomes in terms of patient‐reported outcome measures (PROMs) but were limited by the lack of randomized control trials and consistent comparison groups.ConclusionsThis umbrella review highlights an increase in interest in MAT but underscores the need for higher‐quality reviews with standardized reporting and rigorous methodologies. Future research should focus on long‐term outcomes, optimal surgical techniques, patient selection criteria and risk factors for transplant failure. There is also a need for more studies focusing on MAT in pediatric populations. Overall, this review provides a comprehensive assessment of the current state of research in MAT and identifies areas for improvement in future studies.Level of EvidenceLevel IV.

Clinical outcomes and complications of a non-modular dual-mobility acetabular device, minimum 2 years follow-up.

Non-modular dual-mobility (DM) acetabular bearing constructs are becoming more popular due to their potential advantages for addressing range of motion (ROM) and stability. The objective of this post-market clinical study was to assess clinical outcomes, including patient satisfaction, pain and function, survivorship, and component positioning, in patients ⩾2 years after primary THA using non-modular DM acetabular components. This retrospective, multicentre study evaluated complications and functional outcomes in recipients of non-modular DM acetabular constructs at least 2 years post-THA. Our primary outcomes included the dislocation rate and mean Hip disability and Osteoarthritis Outcomes Score (HOOS). Secondary outcomes included radiographic measurements, patient satisfaction, Forgotten Joint Score (FJS), Harris Hip Score (HHS), and survivorship. 316 eligible patients enrolled in this study across 3 sites, including 168 men (53%) and 148 women (47%). The cohort averaged 5.37 years post-THA (range 2.2-10.1 years) at the study visit. The mean FJS, HHS, and HOOS were good to excellent, with values of 82.3, 90.7, and 92.0, respectively. Patient satisfaction averaged 4.68, between "Very Good" (4) and "Excellent" (5). Minimal radiolucent lines (RLL) surrounded the acetabulum. More RLL surrounded the femur, but most lines were less than 1 mm (4.7% of the study population). There were few adverse events (4 events, 1.3%). Three revisions were performed (0.9%), with one patient requiring removal of the acetabular cup. The high mid- to long-term survivorship and low to no dislocation and reoperation rates indicate this acetabular DM device is a viable option for THA patients. The patient metrics reflect satisfaction, alleviated pain, and restored function with a low risk of adverse outcomes.
