Is Venous Thromboembolism Prophylaxis Needed in Patients Undergoing Knee Arthroscopy? A Prospective Observational Study.

BACKGROUND: Although rare, deep vein thrombosis is a potentially life-threatening complication of knee arthroscopy. There are scanty literature analysing deep vein thrombosis after arthroscopy in Nepal. This study aimed to identify the prevalence of deep vein thrombosis in patients undergoing knee arthroscopy without chemoprophylaxis postoperatively at 2 weeks and 6 weeks, respectively. The study also aimed to estimate the risk of deep vein thrombosis in these patients by using Caprini Risk Assessment Model. METHODS: This prospective observational study was conducted at AKB center, B and B Hospital, Gwarko, Lalitpur, over a period of 16 months. All patients who underwent arthroscopy knee surgeries fulfilling the inclusion criteria were included in the study. The primary outcome measure was the prevalence of deep vein thrombosis as diagnosed by compression color-coded ultrasonography of the popliteal vein and calf vein at 2 weeks and 6 weeks postoperatively. The secondary outcome measure was the prevalence of deep vein thrombosis in the risk groups according to Caprini Risk Assessment Model. RESULTS: Out of 612 patients who underwent arthroscopic knee surgeries during the study period, 2 patients (0.33%) developed deep vein thrombosis at 6 weeks follow-up as diagnosed with ultrasonography of the popliteal and calf veins. The prevalence rate in high-risk group was 0.33% (1 in 307) and in very high-risk group was 5.88% (1 in 17). CONCLUSIONS: There was a low prevalence of deep vein thrombosis without chemoprophylaxis following knee arthroscopy in our study. There was higher prevalence of deep vein thrombosis in very high-risk group patients, so close monitoring of such patients during follow-up is recommended.

[Risk factors for hip osteoarthritis after arthroscopy in patients with femoroacetabular impingement].

OBJECTIVE: To investigate the risk factors of hip osteoarthritis（HOA） after hip arthroscopy in patients with femoro-acetabular impingement（FAI） syndrome, and to reduce and prevent HOA. METHODS: From September 2018 to September 2020, 106 patients with FAI underwent hip arthroscopy, including 40 males and 66 females, aged from 20 to 55 years old with an average age of （33.05±10.19） years old. The mechanism of injury included 51 cases for sports injury, 36 for traffic accidents, and 19 for blunt object injury. The duration of the disease ranged from 5 to 19 days with an average of （12.02±3.69） days. All patients were followed up for 18 months. Patients were divided into HOA group （23 cases） and non-HOA group （83 cases） according to the occurrence of HOA. Multivariate Logistic regression was used to analyze the risk factors of HOA after hip arthroscopy in FAI patients. RESULTS: By univariate analysis, aged from 50 to 70 years old, female, body mass index（BMI）> 30 kg·m-2, physical labor, cam type, postoperative infection, last follow-up hip degree of motion （range of motion, ROM） （flexion, abduction, adduction, internal rotation） and Tönnis grade 1 and above of the HOA group were higher than those of the non-HOA group （P<0.05）, and the relative appendicular skeletal muscle index （RASM） was lower than that of non-HOA group（P<0.05）. By multiple Logistic regression analysis, cam type, BMI>30 kg·m-2, last follow-up hip internal rotation ROM and Tönnis grade 1 were risk factors for HOA after hip arthroscopy in FAI patients （P<0.05）. CONCLUSION: FAI classification, body mass index, hip ROM and Tönnis grade are all related to HOA after hip arthroscopy in FAI patients. Follow-up and intervention should be strengthened in high-risk FAI patients to reduce the occurrence of HOA.

Perioperative Intravenous Dexamethasone Significantly Reduces Postoperative Opioid Requirement and Nausea After Unilateral Elective Hip Arthroscopy: A Randomized Double-blinded Placebo-controlled Trial.

BACKGROUND: Previous studies have shown that dexamethasone has a positive effect on postoperative pain control, opioid consumption, nausea, and vomiting and length of hospital stay after arthroplasty surgery. PURPOSE/HYPOTHESIS: The purpose of this study was to assess whether adding perioperative dexamethasone to our current pain regimen after hip arthroscopy is more effective than a placebo. It was hypothesized that dexamethasone would reduce postoperative pain, reduce opioid consumption, improve subjective pain and nausea scores, and reduce the number of vomiting events. STUDY DESIGN: Randomized controlled trial; Level of evidence, 1. METHODS: A total of 50 patients requiring unilateral elective hip arthroscopy were randomized to receive intravenous dexamethasone immediately before induction of anesthesia and at 8 am on the first postoperative day (2 ×12 mg) or a placebo (sodium chloride 0.9%). The patient, the surgeons, the treating anesthesiologist, and the involved nursing and physical therapy personnel were blinded to group assignment. The primary outcome was postoperative pain, and secondary outcomes were opioid consumption and nausea scores-assessed using a translated revised version of the American Pain Society Patient Outcome Questionnaire 6 hours postoperatively and on days 1 and 2-and vomiting events. A clinical follow-up was performed 12 weeks postoperatively to assess adverse events. RESULTS: The mean age at inclusion was 29 years in both groups. Postoperative pain levels did not differ significantly in most instances. Opioid requirements during the hospitalization in the dexamethasone group were significantly lower than those in the placebo group (31.96 ± 20.56 mg vs 51.43 ± 38 mg; P = .014). Significantly fewer vomiting events were noted in the dexamethasone group (0.15 ± 0.59 vs 0.65 ± 0.91; P = .034). Descriptive data and surgical parameters did not differ significantly. CONCLUSION: Perioperative intravenous dexamethasone significantly reduced postoperative opioid consumption by 40% without compromising pain level and safety, as no corticosteroid-related side effects were observed. Dexamethasone may be a valuable adjuvant to a multimodal systemic pain regimen after hip arthroscopy. REGISTRATION: NCT04610398 (ClinicalTrials.gov identifier).

Prognostic factors for clinical outcomes after arthroscopic treatment of traumatic central tears of the triangular fibrocartilage complex.

Aims: The study aimed to assess the clinical outcomes of arthroscopic debridement and partial excision in patients with traumatic central tears of the triangular fibrocartilage complex (TFCC), and to identify prognostic factors associated with unfavourable clinical outcomes. Methods: A retrospective analysis was conducted on patients arthroscopically diagnosed with Palmer 1 A lesions who underwent arthroscopic debridement and partial excision from March 2009 to February 2021, with a minimum follow-up of 24 months. Patients were assessed using the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, Mayo Wrist Score (MWS), and visual analogue scale (VAS) for pain. The poor outcome group was defined as patients whose preoperative and last follow-up clinical score difference was less than the minimal clinically important difference of the DASH score (10.83). Baseline characteristics, arthroscopic findings, and radiological factors (ulnar variance, MRI, or arthrography) were evaluated to predict poor clinical outcomes. Results: A total of 114 patients were enrolled in this study, with a mean follow-up period of 29.8 months (SD 14.4). The mean DASH score improved from 36.5 (SD 21.5) to 16.7 (SD 14.3), the mean MWS from 59.7 (SD 17.9) to 79.3 (SD 14.3), and the mean VAS pain score improved from 5.9 (SD 1.8) to 2.2 (SD 2.0) at the last follow-up (all p < 0.001). Among the 114 patients, 16 (14%) experienced poor clinical outcomes and ten (8.8%) required secondary ulnar shortening osteotomy. Positive ulnar variance was the only factor significantly associated with poor clinical outcomes (p < 0.001). Positive ulnar variance was present in 38 patients (33%); among them, eight patients (21%) required additional operations. Conclusion: Arthroscopic debridement alone appears to be an effective and safe initial treatment for patients with traumatic central TFCC tears. The presence of positive ulnar variance was associated with poor clinical outcomes, but close observation after arthroscopic debridement is more likely to be recommended than ulnar shortening osteotomy as a primary treatment.

Long-term Outcomes of Primary Hip Arthroscopy: Multicenter Analysis at Minimum 10-Year Follow-up With Attention to Labral and Capsular Management.

BACKGROUND: Hip arthroscopy is rapidly advancing, with positive published outcomes at short- and midterm follow-up; however, available long-term data remain limited. PURPOSE: To evaluate outcomes of primary hip arthroscopy at a minimum 10-year follow-up at 2 academic centers by describing patient-reported outcomes and determining reoperation and total hip arthroplasty (THA) rates. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Patients with primary hip arthroscopy performed between January 1988 and April 2013 at 2 academic centers were evaluated for postoperative patient-reported outcomes-including the visual analog scale, Tegner Activity Scale score, Hip Outcome Score Activities of Daily Living and Sport Specific subscales, modified Harris Hip Score, Nonarthritic Hip Score, 12-item International Hip Outcome Tool, surgery satisfaction, and reoperations. RESULTS: A total of 294 patients undergoing primary hip arthroscopy (age, 40 ± 14 years; 66% women; body mass index, 27 ± 6) were followed for 12 ± 3 years (range, 10-24 years) postoperatively. Labral debridement and repair were performed in 41% and 59% of patients, respectively. Of all patients who underwent interportal capsulotomy, 2% were extended to a T-capsulotomy, and 11% underwent capsular repair. At final follow-up, patients reported a mean visual analog scale at rest of 2 ± 2 and with use of 3 ± 3, a 12-item International Hip Outcome Tool of 68 ± 27, a Nonarthritic Hip Score of 81 ± 18, a modified Harris Hip Score of 79 ± 17, and a Hip Outcome Score Activities of Daily Living of 82 ± 19 and Sport Specific subscale of 74 ± 25. The mean surgical satisfaction was 8.4 ± 2.4 on a 10-point scale, with 10 representing the highest level of satisfaction. In total, 96 hips (33%) underwent reoperation-including 65 hips (22%) converting to THA. THA risk factors included older age, higher body mass index, lower lateral center-edge angle, larger alpha angle, higher preoperative Tönnis grade, as well as labral debridement and capsular nonrepair (P≤ .039). Patients undergoing combined labral and capsular repair demonstrated a THA conversion rate of 3% compared with 31% for patients undergoing combined labral debridement and capsular nonrepair (P = .006). Labral repair trended toward increased 10-year THA-free survival (84% vs 77%; P = .085), while capsular repair demonstrated significantly increased 10-year THA-free survival (97% vs 79%; P = .033). CONCLUSION: At a minimum 10-year follow-up, patients undergoing primary hip arthroscopy demonstrated high satisfaction and acceptable outcome scores. In total, 33% of patients underwent reoperation-including 22% who underwent THA. Conversion to THA was associated with patient factors including older age, higher Tönnis grade, and potentially modifiable surgical factors such as labral debridement and capsular nonrepair.

Venous Thromboembolism Chemical Prophylaxis in Patients Undergoing Shoulder Arthroscopy.

¼ Venous thromboembolism (VTE) after shoulder arthroscopy is rare (0.01%-0.38%) but impacts a significant number of patients because of the high procedure volume.¼ Studies found no significant benefit in reducing VTE risk with aspirin or low-molecular-weight heparins.¼ Current guidelines for thromboprophylaxis in shoulder arthroscopy lack consensus and need patient-specific considerations.¼ Further research is required to develop evidence-based thromboprophylaxis guidelines for shoulder arthroscopy.

Sequential surgery for the treatment of type I knee ankylosis: a series of 62 cases.

BACKGROUNDS: The lack of systematic classification and standard treatment principles for knee ankylosis prevents optimal treatments. This study explored treatments for type I (mild) knee joint ankylosis. METHOD: This retrospective study analysed patients with knee joint ankylosis admitted from March 2013 to January 2018 who underwent sequential arthroscopic release. RESULT: The 62 patients had 12-36 (average, 18) months of follow-up. Thirty-eight patients were released; of these, 18 were assisted by limited incision with partial quadriceps femoris expansion myotomy and released according to arthroscopy. Six patients underwent lengthening and release of the quadriceps femoris. All surgeries combined with full-course rehabilitation resulted in improved joint mobility. The range of motion (ROM) of the knee joint recovered to a range of 0° to 85°-140° (mean: 118.32 ± 9.42°) from the preoperative range of 30°-70° (mean: 45° ± 15.50°). The clinical effect was evaluated according to the Judet criteria at the final follow-up. The outcomes at the last follow-up (at least for 1 year) were excellent in 55 cases, good in six cases, and fair in one case. CONCLUSION: Sequential arthroscopic release, minimal selective invasion of limited incision of partial quadriceps femoris expansion myotomy, assisted by pie-crusting technique to release, or quadriceps femoris lengthening, and release surgery for type I knee joint ankylosis, accompanied by early rehabilitation training provided satisfactory results without significant complications.

Risk of suprascapular nerve injury in open Trillat procedure: an anatomical study.

PURPOSE: The open Trillat Procedure described to treat recurrent shoulder instability, has a renewed interest with the advent of arthroscopy. The suprascapular nerve (SSN) is theoretically at risk during the drilling of the scapula near the spinoglenoid notch. The purpose of this study was to assess the relationship between the screw securing the coracoid transfer and the SSN during open Trillat Procedure and define a safe zone for the SSN. METHODS: In this anatomical study, an open Trillat Procedure was performed on ten shoulders specimens. The coracoid was fixed by a screw after partial osteotomy and antero-posterior drilling of the scapular neck. The SSN was dissected with identification of the screw. We measured the distances SSN-screw (distance 1) and SSN-glenoid rim (distance 2). In axial plane, we measured the angles between the glenoid plane and the screw (α angle) and between the glenoid plane and the SSN (ß angle). RESULTS: The mean distance SSN-screw was 8.8 mm +/-5.4 (0-15). Mean α angle was 11°+/-2.4 (8-15). Mean ß angle was 22°+/-6.7 (12-30). No macroscopic lesion of the SSN was recorded but in 20% (2 cases), the screw was in contact with the nerve. In both cases, the ß angle was measured at 12°. CONCLUSION: During the open Trillat Procedure, the SSN can be injured due to its anatomical location. Placement of the screw should be within 10° of the glenoid plane to minimize the risk of SSN injury and could require the use of a specific guide or arthroscopic-assisted surgery.

The relevance of knee arthroscopy photographs in medicolegal proceedings.

PURPOSE: Whether photographs included in the operative report of knee arthroscopies can make the surgeon liable in the event of a legal investigation remains unknown. The main objective of this study was to establish inter-observer reliability in determining the presence or absence of lesions of the cartilage, meniscus and anterior cruciate ligament (ACL). Secondary objective was to assess the inter-observer reliability in classifying lesions. METHOD: A retrospective observational study was conducted in a continuous serie of 60 patients who underwent knee arthroscopy from the same operator. The photographs of each patient's operative report were presented separately to three experts, blinded to each other. Each expert had to decide on the presence or absence of injuries to the following structures: meniscal, cartilage and ACL and then, classify it. Primary and secondary endpoints were evaluated using the Fleiss' kappa index. RESULTS: Inter-observer reliability for lesion detection was between 0.4 and 0.61 for all structures with three exceptions: for cartilage, it was low (0.15) at the lateral tibial plateau and poor (-0.01) at the external condyle. On the contrary, the concordance was almost perfect (0.8) for the ACL. For classifying cartilaginous and meniscal lesions, inter-observer reliability was poor (from 0.03 to 0.14), except for at the lateral meniscus (0.65). CONCLUSION: Inter-observer reliability of arthroscopic knee diagnoses is poor when photographs alone are used. In the event of a legal investigation following knee arthroscopy, the photographs included in the operative report should not be used alone to hold the surgeon liable.

Arthroscopic ankle surgery in people with haemophilia.

INTRODUCTION: People with haemophilia (PWH) not administered primary haematological prophylaxis since childhood, that is, those treated haematologically on demand or not treated at all, often experience the degeneration of the ankles, leading to pain and functional impairment. AIM: To analyse the outcomes and complications of arthroscopic ankle surgery performed on PWH. METHODS: For this narrative review of the literature, a search was conducted in PubMed on 2, December 2023, using the keywords "haemophilia", "ankle" and "arthroscopy". Of the 29 articles identified, 15 specifically related to ankle arthroscopy in PWH were selected (inclusion criterion). The remaining articles did not meet this requirement (exclusion criterion) and were therefore eliminated. RESULTS: Arthroscopic procedures (arthroscopic synovectomy, debridement and arthrodesis of the ankle) are increasingly used in the surgical treatment of haemophilic ankle arthropathy. Although arthroscopic ankle surgery offers good outcomes in patients with haemophilia, the procedure is not free of complications, which range from 7.9% for arthroscopic ankle debridement to 13.1% in arthroscopic ankle synovectomy and 17.8% in arthroscopic ankle arthrodesis, respectively. The non-union rate of arthroscopic ankle arthrodesis is 7.1% (2/28). CONCLUSION: Although arthroscopic interventions in the haemophilic ankle (synovectomy, debridement, arthrodesis) offer good functional outcomes, they are associated with a non-negligible rate of complications. Arthroscopic ankle surgery in PWH is major surgery and should be treated as such.

Complications after arthroscopic triangular fibrocartilage complex (TFCC) surgery.

Wrist arthroscopy is a valuable and widely utilized tool in the treatment of triangular fibrocartilage complex (TFCC) injuries. These procedures include synovectomy alone, peri-capsular or transosseous repair, and arthroscopic-assisted reconstruction, and each are associated with specific complications. This review describes the types of complications and their rates in different types of arthroscopic TFCC surgery reported in the literature and in our centre. Across the spectrum of arthroscopic TFCC surgery, complication rates and the learning curve increase with surgical complexity. Relevant anatomy, prevention and management of complications including nerve injury and irritation, extensor tendon injury and tendinitis, fracture, stiffness, and persistence of symptoms or instability are discussed. Vigilance to anatomical details and careful dissection can help to reduce complications that may result in disturbing pain and functional loss.

Hip Capsulolabral Complex: Anatomy, Disease, MRI Features, and Postoperative Appearance.

The hip is a uniquely constrained joint with critical static stability provided by the labrum, capsule and capsular ligaments, and ligamentum teres. The labrum is a fibrocartilaginous structure along the acetabular rim that encircles most of the femoral head. Labral tears are localized based on the clock-face method, which determines the extent of the tear while providing consistent terminology for reporting. Normal labral variants can mimic labral disease and can be differentiated by assessment of thickness or width, shape, borders, location, and associated abnormalities. The Lage and Czerny classification systems are currently the most well-known arthroscopic and imaging systems, respectively. Femoroacetabular impingement is a risk factor for development of labral tears and is classified according to bone dysmorphisms of the femur ("cam") or acetabulum ("pincer") or combinations of both (mixed). The capsule consists of longitudinal fibers reinforced by ligaments (iliofemoral, pubofemoral, ischiofemoral) and circular fibers. Capsular injuries occur secondary to hip dislocation or iatrogenically after capsulotomy. Capsular repair improves hip stability at the expense of capsular overtightening and inadvertent chondral injury. The ligamentum teres is situated between the acetabular notch and the fovea of the femoral head. Initially considered to be inconsequential, recent studies have recognized its role in hip rotational stability. Existing classification systems of ligamentum teres tears account for injury mechanism, arthroscopic findings, and treatment options. Injuries to the labrum, capsule, and ligamentum teres are implicated in symptoms of hip instability. The authors discuss the labrum, capsule, and ligamentum teres, highlighting their anatomy, pathologic conditions, MRI features, and postoperative appearance. ©RSNA, 2024 Test Your Knowledge questions for this article are available in the supplemental material.

The Septic Elbow Joint: Treatment Approaches for Improved Patient Outcomes.

Septic arthritis of the elbow is a serious problem requiring prompt, accurate diagnosis and urgent surgical intervention. Achieving successful patient outcomes depends heavily on early diagnosis and efficient streamlined surgical treatment. Essential tactics for treating the septic elbow joint include immediate joint irrigation and debridement in addition to administration of appropriate antibiotics. This comprehensive review delves into the cause of the septic elbow joint, identifies associated risk factors, and provides a comprehensive approach encompassing the diagnosis and treatment of the septic elbow. The aim of this review is to optimize patient care and outcomes.

Bilateral Os Trigonum Fracture Treated With Simultaneous Posterior Ankle Arthroscopy.

This is a case report of a 21-year-old female undergraduate student who sustained bilateral ankle injuries while jumping from a moving van wearing 3-inch high heel shoes. Upon initial presentation, her injury was treated conservatively as an acute bilateral ankle sprain for 6 weeks. However, the patient reported no improvement of pain and remained unable to self-ambulate. Bilateral MRI and CT scans of both ankles demonstrated bilateral os trigonum fractures. She underwent bilateral posterior ankle arthroscopic débridement of both os trigonum. At the postoperative 36-month follow-up, the patient reported notable improvement of all functional outcomes (36-item Short Form survey and Foot and Ankle Ability Measure), reported return to the same level of sports activities, and experienced no pain (visual analog scale) on either ankle. This is the first report in the literature of bilateral os trigonum fracture treated with simultaneous posterior ankle arthroscopic débridement.

Comparison of the incidence of inadvertent perioperative hypothermia between general anesthesia and interscalene brachial plexus block in shoulder arthroscopy: A randomized prospective study.

INTRODUCTION: Inadvertent perioperative hypothermia (IPH), defined as core body temperature below 36°C, is associated with various complications. Shoulder arthroscopy is a risk factor of IPH. This study aimed to compare the incidence of IPH between general anesthesia (GA) and interscalene brachial plexus block (ISBPB) for shoulder arthroscopy. METHOD: Patients scheduled for shoulder arthroscopy were prospectively enrolled and randomly assigned to GA or ISBPB groups. The body temperature of the patients was measured from baseline to the end of anesthesia and in the post-anesthetic care unit to compare the incidence of IPH. RESULTS: Of the 114 patients initially identified, 80 were included in the study (GA = 40, ISBPB = 40). The incidence of IPH differed significantly between the groups, with GA at 52.5% and ISBPB at 30.0% (P = .04). Profound IPH (defined as < 35.0°C) occurred in 2 patients with GA. Upon arrival at the post-anesthesia care unit, the GA group exhibited a significantly lower mean body temperature (35.9 ±â€…0.6°C) than the ISBPB group (36.1 ±â€…0.2°C, P = .04). CONCLUSION: The incidence of IPH in the GA group was higher than that in the ISBPB group during shoulder arthroscopy, suggesting that ISBPB may be a preferable anesthetic technique for reducing risk of IPH in such procedures.

No difference in prevalence of postoperative iliopsoas tendinitis in patients undergoing arthroscopic hip surgery when using absorbable versus non-absorbable suture for capsular closure.

PURPOSE: The volume of arthroscopic hip surgery has increased dramatically in recent years with iliopsoas tendinitis (IPT) being one of the most common complications of this procedure. The purpose of this study is to investigate the prevalence of post-operative IPT in patients who undergo arthroscopic hip surgery with capsular closure using absorbable versus non-absorbable suture. METHODS: This is a single center, single surgeon, retrospective analysis performed between August 2007 and May 2023 comparing two cohorts who underwent hip arthroscopy. Patients were divided into those who underwent surgery with capsular closure using absorbable (Vicryl®, Johnson and Johnson, New Brunswick, NJ) suture and those who underwent capsular closure with non-absorbable suture (Suturetape, Arthrex, Naples FL). All patients who underwent primary or revision hip arthroscopy and were at least 2 months post-operation were initially included in the study. RESULTS: Between August 2007 and May 2023 a total of 1513 hip arthroscopy surgeries were performed. Within this cohort, 1421 hips underwent hip arthroscopy with non-absorbable suture and 64 hips underwent surgery with absorbable suture. There was no significant difference between the proportion of IPT in the non-absorbable cohort (2.3%) versus the absorbable cohort (1.6%) (P = 0.669). CONCLUSION: Capsular closure with Absorbable sutures was non-inferior to capsular closure with non-absorbable sutures with respect to the proportion of post-operative IPT following hip arthroscopy for FAI. Additionally, the proportion of post-operative IPT was found to be significantly higher in patients undergoing revision versus primary hip arthroscopy, regardless of capsular closure suture type. LEVEL OF EVIDENCE: IV.

Comparative analyses of arthroscopic and open repairs of lateral ligament complex injuries of the ankle: a systematic review and meta-analysis of the medium-term outcomes.

PURPOSE: Little is known regarding the comparative analyses of the medium-term outcomes (with a mean minimum follow-up period of 24 months), between arthroscopic and open repairs of lateral ligament complex (LLC) injuries of the ankle. Thus, in this study, we aimed to explore the comparative analyses regarding the medium-term follow-up outcomes of these repairs, by conducting a systematic review and meta-analysis. METHODS: The systematic review and meta-analysis were performed as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines; data were extracted from the PubMed and Google Scholar databases. From an initial search, a total of 1182 abstracts (280 and 902 abstracts, from PubMed and Google Scholar, respectively) were found and screened in accordance with the eligibility criteria. Subsequently, six articles were found to be eligible for further review. RESULTS: A total of 419 patients underwent surgical repairs; 205 and 214 patients underwent arthroscopic and open repairs, respectively. The mean minimum follow-up period was 29.2 months. The medium-term follow-up for arthroscopic LLC repairs was found to be superior to that of open LLC repairs, with more favorable outcomes; as evidenced by better clinical scores, lower pooled complication rates, earlier return times to pre-injury sport, and higher early sport ratios. CONCLUSIONS: The findings of this systematic review and meta-analysis support near-future developments validating arthroscopic repair as the new gold standard for LLC repairs, similarly to arthroscopic ligament and tendon repairs, as well as arthroscopic reconstruction surgeries, of the knee and shoulder.

The effect of block side on hemodynamic and respiratory parameters in patients who had interscalene block for upper limb surgery.

OBJECTIVE: The administration of interscalene block (ISB) may lead to several hemodynamic effects, likely due to the diffusion of local anesthetic to nearby structures such as carotid sinus baroreceptors. This study aimed to compare hemodynamic and respiratory changes resulting from right and left-sided ISB. PATIENTS AND METHODS: A retrospective analysis was conducted on adults who had ultrasound-guided ISB for upper limb surgery between January 2020 and December 2021. All patients had ISB with bupivacaine 0.5% and lidocaine 2% mixture following premedication. Demographic data, arterial blood pressure, heart rate, and peripheral oxygen saturation (SpO2) were measured before and after the block at regular intervals. Block characteristics, surgical and post-anesthesia care unit (PACU) durations, intraoperative analgesic requirements, and side effects were analyzed. RESULTS: A total of 94 patients had ISB for upper limb surgery, 54 for the right and 40 for the left-sided surgeries. Patients' data were analyzed in two groups according to the block side. Increased arterial blood pressure was observed in both groups after the block compared to the control values. Systolic arterial pressure from 10 to 30 minutes, diastolic arterial pressure at the 25th minute, and mean arterial pressure at the 15th, 20th, and 25th minutes were significantly higher on the right-sided blocks. Heart rate, SpO2, analgesic requirements, block characteristics, and PACU durations did not differ between the groups. CONCLUSIONS: Ultrasound-guided ISB-applied patients demonstrated increased blood pressure compared to control values. This increase, without concurrent changes in heart rate, was more pronounced in right-sided ISB. These findings indicate that careful hemodynamic monitoring is necessary whenever hypertension should be avoided for the patients.

[Progress on study of factors influencing the prognosis and complications of surgery for discoid meniscus injury in children].

The discoid meniscus is a common congenital meniscal malformation that is prevalent mainly in Asians and often occurs in the lateral discoid meniscus. Patients with asymptomatic discoid meniscus are usually treated by conservative methods such as observation and injury avoidance, while patients with symptoms and tears need to be treated surgically. Arthroscopic saucerization combined with partial meniscectomy and meniscus repair is the most common surgical approach., and early to mid-term reports are good. The prognostic factors are the patient's age at surgery、follow-up time and type of surgery. Some patients experience complications such as prolonged postoperative knee pain, early osteoarthritis, retears and Osteochondritis dissecans. The incidence of prolonged postoperative knee pain was higher and the incidence of Osteochondritis dissecans was the lowest. Retears of the lateral meniscus is the main reason for reoperation.

Predictors of Postoperative Patient-Reported Outcome Measure Response Rates Among Patients With Rotator Cuff Repair.

BACKGROUND: Patient-reported outcome measures (PROMs) contribute to evaluating and improving the quality of patient care. Patient outcomes after rotator cuff repair (RCR) have been researched; however, the relationship between PROM response rates and individual and health care correlates has not been thoroughly investigated. PURPOSE: To examine differences in individual and health care factors among patients who had undergone RCR based on their PROM response rates. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: Shoulder-specific and general PROMs were solicited via email and text message of all patients who underwent RCR between 2016 and 2020. Three subgroups were classified: (1) complete responders completed all 1-year postoperative PROMs, (2) partial responders answered enough questions to produce ≥1 usable score, and (3) nonresponders did not respond to a single measure. Correlates were assessed using analysis of variance and chi-square tests. Adjusted multinomial logistic regression models identified predictors of 1-year PROM response. RESULTS: Of 2195 patients included at the 1-year follow-up, 34% were complete responders; 11%, partial responders; and 55%, nonresponders. Patients had a mean age of 61.8 years, 63% were men, and 90% were White. Pre- and postoperative PROM scores were similar across responder groups. In stepwise selection, 1-year responses (complete or partial) were associated with older age, later year of surgery, White race, and having workers' compensation insurance. The strongest predictor of PROM response was having workers' compensation insurance. CONCLUSION: Patients with workers' compensation insurance compared with other insurance types responded to PROMs at disproportionately higher rates. This could distort postoperative PROM scores in the population studied because there are known differences among patients with this insurance status.
