Meniscal ramp lesion classification systems: A systematic review.

PURPOSE: To describe the proposed classification systems for meniscal ramp lesions (RLs) in the literature and evaluate their accuracy and reliability. METHODS: A systematic search was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-analyses guidelines utilising PubMed, Embase and Cochrane Library databases. Level I-IV studies referencing RLs along with either an arthroscopic- or magnetic resonance imaging (MRI)-based classification system used to describe RL subtypes were included. RESULTS: In total, 21 clinical studies were included. Twenty-seven (79%) of the included studies were published in 2020 or later. There were four main classification systems proposed within the literature (two arthroscopic-, two MRI-based), describing tear patterns, mediolateral extent, associated ligament disruption and stability of the lesion. The first classification was proposed in 2015 by Thaunat et al. and is referenced in 22 (64.7%) of the included studies. The application of the Thaunat et al. criteria to MRI showed variable sensitivity (31.70%-93.8%) and interobserver agreement (k = 0.55-0.80). The Greif et al. modification to the Thaunat et al. system was referenced in 32.4% of the included studies and had a substantial interobserver agreement (k = 0.8). Stability to probing and specific tear location were each used to classify RLs in 28.6% and 23.8% of the included clinical studies, respectively. CONCLUSION: Although there has been a recent increase in the recognition and treatment of meniscal RLs, there is limited consistency in descriptive classifications used for this pathology. Current RL classification systems based on preoperative MRI have variable reliability, and arthroscopic examination remains the gold standard for diagnosis and classification. LEVEL OF EVIDENCE: Level IV.

Association of dietary patterns with sarcopenia in adults aged 50 years and older.

PURPOSE: Although numerous studies have investigated the impact of dietary factors on the prevention of decreased muscle mass and function, limited research has examined the relationship between dietary patterns and sarcopenia. This study aimed to assess the associations between dietary patterns, and sarcopenia, muscle strength, and mass in adults following a Mediterranean diet residing in southern Italian cities. METHODS: This cross-sectional study utilized data from an existing database, comprising 528 individuals aged 50 years or older who underwent health-screening tests at the Clinical Nutrition Unit of the "R.Dulbecco" University Hospital. Strength was assessed through handgrip strength, and appendicular skeletal muscle mass was estimated using bioelectrical impedance analysis. Dietary intake information was collected through a food frequency questionnaire linked to the MetaDieta 3.0.1 nutrient composition database. Principal Component Analysis, a statistical technique identifying underlying relationships among different nutrients, was employed to determine dietary patterns. Multinomial logistic regression analysis was conducted to estimate the odds ratio for sarcopenia or low handgrip strength in relation to the lowest tertile of dietary pattern adherence compared to the highest adherence. RESULTS: The participants had a mean age of 61 ± 8 years. Four dietary patterns were identified, with only the Western and Mediterranean patterns showing correlations with handgrip strength and appendicular skeletal muscle mass. However, only the Mediterranean pattern exhibited a correlation with sarcopenia (r = - 0.17, p = 0.02). The highest tertile of adherence to the Mediterranean dietary pattern demonstrated significantly higher handgrip strength compared to the lowest tertile (III Tertile: 28.3 ± 0.5 kg vs I Tertile: 26.3 ± 0.5 kg; p = 0.01). Furthermore, even after adjustment, the highest tertile of adherence to the Mediterranean pattern showed a significantly lower prevalence of sarcopenia than the lowest adherence tertile (4% vs 16%, p = 0.04). The lowest adherence to the Mediterranean dietary pattern was associated with increased odds of having low muscle strength (OR = 2.38; p = 0.03; 95%CI = 1.05-5.37) and sarcopenia (OR = 9.69; p = 0.0295; %CI = 1.41-66.29). CONCLUSION: A high adherence to the Mediterranean dietary pattern, characterized by increased consumption of legumes, cereals, fruits, vegetables, and limited amounts of meat, fish, and eggs, is positively associated with handgrip strength and appendicular skeletal muscle mass. The highest adherence to this dietary model is associated with the lowest odds of low muscle strength and sarcopenia. Despite the changes brought about by urbanization in southern Italy compared to the past, our findings continue to affirm the superior benefits of the Mediterranean diet in postponing the onset of frailty among older adults when compared to other dietary patterns that are rich in animal foods.

A nutraceutical with Citrus bergamia and Cynara cardunculus improves endothelial function in adults with non-alcoholic fatty liver disease.

OBJECTIVE: Polyphenol intake may prevent hepatic steatosis and cardiovascular disease by potentially improving endothelial function. The purposes of this study are to investigate the association between fatty liver disease and endothelial dysfunction and to test the effects of a nutraceutical containing extracts made from Citrus bergamia and Cynara cardunculus on peripheral vascular endothelial function in adults with liver steatosis. METHODS: We analyzed data from 32 individuals with hepatic steatosis and endothelial dysfunction (reactive hyperemia index ≤ 1.67). Sixteen subjects took 1 capsule/d (300 mg/d) containing Cynara cardunculus extract and bergamot polyphenol fraction, while the other 16 subjects matched for age, sex, and body mass index took 1 capsule/d of placebo (maltodextrin) for 12 wk. All anthropometric parameters were assessed at baseline and after 12 wk as were lipids, glucose, and reactive hyperemia index using an EndoPAT 2000. RESULTS: The mean age was 52 ± 9 y. The mean reactive hyperemia index was 1.15 ± 0.4. After 12 wk, we found a greater increase in reactive hyperemia index in the participants taking the nutraceutical rather than placebo (0.58 ± 0.5 versus 0.13 ± 0.5; P = 0.02, respectively). The stepwise multivariable analysis confirmed a positive association between reactive hyperemia index change and the nutraceutical treatment (B = 0.38; P = 0.025) and negative association with reactive hyperemia index values at baseline (B = -0.81; P < 0.001). No association was found between the reduction in the amount of intrahepatic fat and the improvement of endothelial function (B = 0.002; P = 0.56). CONCLUSIONS: A nutraceutical containing bergamot and artichoke extracts improves peripheral vascular endothelial function in adults with hepatic steatosis and early phase of atherosclerosis.

How to Avoid Common Complications in Hamstrings Harvest for Anterior Cruciate Ligament Reconstruction: A Practical Guide.

More than 100,000 anterior cruciate ligament (ACL) reconstructions are performed annually in the United States and one of the most common autografts for ACL reconstruction (ACLR) is the HS tendons. Nevertheless, proper HS harvest can be challenging, and several complications can be encountered, including, iatrogenic neurovascular damage, premature amputation of the tendons, graft contamination, and postoperative hematoma. The aim of this technical note is to describe a safe and effective technique for autologous HS tendon harvest in ACLR.

Efficacy of intra-articular injections of hyaluronic acid in patients with glenohumeral joint osteoarthritis: A systematic review and meta-analysis.

Symptomatic primary glenohumeral (GH) joint osteoarthritis (OA) can be challenging to treat. Hyaluronic acid (HA) has emerged as a promising treatment for the nonsurgical management of GH-OA. In this systematic review with meta-analysis, we aimed to evaluate the current evidence regarding the efficacy of intra-articular HA on pain relief in patients suffering from GH-OA. A total of 15 studies (only randomized controlled trials providing data at the end of the intervention) were included. The relevant studies were selected based on the following PICO model: P: patients with diagnosis of shoulder OA; I: HA infiltrations as therapeutic intervention administered; C: no restriction for comparators assessed; O: pain, in terms of visual analog scale (VAS) or numeric rating scale. The risk of bias among the included studies was estimated using the PEDro scale. A total of 1023 subjects were analyzed. Comparing HA injections combined with physical therapy (PT) compared to PT alone resulted in superior scores, showing an overall effect size (ES) of 4.43 (p = 0.00006). Moreover, pooled analysis of VAS pain scores demonstrated a significant improvement in the ES of the HA in comparison with corticosteroid injections (p = 0.002). On average, we reported a PEDro score of 7.2. A total of 46.7% of studies showed probable signs of a randomization bias. The findings of this systematic review and meta-analysis showed that IA injections of HA might be effective on pain relief with significant improvements compared to baseline and compared to corticosteroid injections in patients affected by GH-OA.

Therapeutic Fasting in Reducing Chemotherapy Side Effects in Cancer Patients: A Systematic Review and Meta-Analysis.

The aim of this study was to assess the available evidence regarding the effect of a variety of fasting-like regimens on preventing chemotherapy-related side effects. PubMed, Scopus and Embase were used to select the studies for this review, which concluded on 24 November 2022. All types of clinical trials and case series reporting chemotherapy toxicity associated with fasting regimens and any comparison were considered. A total of 283 records were identified, of which 274 were excluded, leaving only nine studies that met the inclusion criteria. Five of these trials were randomized. Overall, moderate to high-quality evidence showed that several fasting regimens did not provide benefits compared to a conventional diet or other comparators in reducing the risk of adverse events. The overall pooled estimate for a variety of fasting regime when compared to non-fasting, indicated no significant difference in the side effects (RR = 1.10; 95% CI: 0.77-1.59; I2 = 10%, p = 0.60), including neutropenia alone (RR = 1.33; 95% CI: 0.90-1.97; I2 = 0%, p = 0.15). A sensitivity analysis confirmed these results. Based on our systematic review and meta-analysis, there is currently no evidence supporting the superiority of therapeutic fasting over non-fasting in preventing chemotherapy toxicity. The development of cancer treatment that do not entail toxicities remains imperative.

Subacromial Balloon Spacer for Massive Irreparable Rotator Cuff Tears.

Massive irreparable rotator cuff tears (MIRCTs) represent 10% to 40% of cases of rotator cuff abnormality and are challenging to treat. When MIRCTs are unresponsive to nonoperative treatment, surgery may be considered. An arthroscopically inserted biodegradable subacromial balloon spacer (InSpace; Stryker) has grown in popularity in recent years for treatment of patients with MIRCTs. The balloon spacer is made of a copolymer of poly-L-lactide-eco-ε-caprolactone and is expected to fully resorb within 12 months after implantation. Research has suggested the balloon spacer becomes progressively compressed and is slowly replaced with fibrous tissue between the humeral head and the acromion, which may support a prolonged benefit following resorption. Clinical benefits may be achieved through reduced acromiohumeral abutment and subacromial friction during shoulder movement by lowering the humeral head and facilitating humeral gliding. The primary population indicated for use of the implant are patients older than 40 years with persistent shoulder pain and functional disability due to MIRCTs. Contraindications include irreparable subscapularis tears, moderate to severe arthritis, axillary nerve palsy, and known allergy to the implant material. There are not clear indications for use of the implant for treatment of partial-thickness tears or repairable complete rotator cuff tears. Familiari et al. reported that treatment with the balloon spacer was associated with a significant improvement in shoulder function, limited need for revision surgery, and high satisfaction at mean 3-year follow-up. More recently, a prospective multicenter randomized controlled trial was conducted to evaluate the efficacy and safety of the balloon spacer in 93 patients compared to 91 patients undergoing arthroscopic partial repair. Significant and clinically relevant improvements in the American Shoulder and Elbow Surgeons score from baseline were noted in both groups up to the 2-year follow-up.

Anatomy of the anterior cruciate ligament and the common autograft specimens for anterior cruciate ligament reconstruction.

A thorough understanding of the anatomical properties of the native anterior cruciate ligament (ACL), as well as the native specimens that are most commonly considered as viable autograft choices for anterior cruciate ligament reconstruction (ACLR), is warranted for continuing to pursue the best-possible graft choice for patients undergoing ACLR. While a wide variety of graft choices remain available to the operating surgeon, choosing the correct graft choice remains a consideration and discussion with patients on the pros and cons of each option. This article combines a review of the current literature on the quantitative and qualitative anatomy of the native ACL and common autograft specimens with the expert consensus of the senior author on the surgically-pertinent anatomy of these structures. The purpose of this article is to review the anatomy pertaining to the native ACL, along with the distal anatomy of the hamstring tendons, patellar tendon and quadriceps tendon (QT). Multiple tendinous and ligamentous structures exist around the knee that serve as viable candidates for use as autologous grafts for ACLR, and the anatomy of these distal extents of these structures are discussed thoroughly, including bony attachments, quantitative and relational anatomy, cross sectional area, and histological features of these structures.

Shoulder arthroplasty in patients with glenohumeral osteoarthritis, glenoid bone loss and an intact rotator cuff: an algorithmic approach and review of the literature.

In patients with severe glenohumeral osteoarthritis (OA) and preserved rotator cuff function who have failed nonoperative treatment, anatomic total shoulder arthroplasty (TSA) has historically been the preferred surgical treatment. Shoulder arthroplasty in the setting of glenoid bone loss setting is technically demanding. Many techniques have been described to deal with glenoid bone loss including eccentric reaming, bone grafting, augmented glenoid baseplates, and patient-specific implants. Still, the decision to perform anatomic TSA or reverse total shoulder arthroplasty (RTSA) is often unclear, especially as the use of RTSA increases and evolves, making historical studies less useful when considering modern implant designs. RTSA has been advocated as a solution for patients with severe glenoid bone loss with intact rotator cuff function. Moreover, in appropriately selected patients, good outcomes can be achieved without the use of bone grafting or augmented baseplates. In cases of severe glenoid bone loss, RTSA can be performed with reaming the glenoid flat such that the baseplate rests on native glenoid bone. We have previously reported excellent prosthetic survival with this technique at 5-year follow-up. The purpose of this article is to highlight our suggested treatment algorithm for glenohumeral OA with glenoid bone loss and intact rotator cuff. Specifically, we focus on situations where RTSA may be preferred as opposed to anatomic TSA, and our suggested approach to managing bone loss intraoperatively in this complex patient population.

Biomarkers for Osteoarthritis Diseases.

Growing evidence has revealed the pivotal role of inflammatory biomarkers in the pathogenesis of osteoarthritis. There is significant interest in the prognostic value of select biomarkers, given the potential for early identification and treatment of patients at risk of osteoarthritis prior to the development of irreversible clinical disease. Clinical trials of novel therapeutics that disrupt the inflammatory pathways of osteoarthritis are also ongoing. The purpose of this review is to summarize the current literature on key biomarkers within the context of osteoarthritis pathogenesis, clinical symptom development, and treatment capabilities. Multiple recent studies have established biomarkers that signal the existence of osteoarthritis pathology and the development of clinical symptomology. However, prior to implementation in clinical practice, additional research is required to precisely define the prognostic value for numerous biomarkers and standardize their measurement. Biomarker-driven investigations represent a promising avenue for the early diagnosis and treatment of osteoarthritis.

Arthroscopic Repair of Posterior Root Tears of the Lateral Meniscus with All-Suture Anchor.

Meniscus root tears are increasingly being recognized and treated because of improved awareness and diagnostics. These injuries commonly occur in combination with knee ligament injuries. Untreated posterior meniscus root teats have been demonstrated to increase contact pressure and decrease contact area, ultimately leading to unfavorable joint loading and development of early osteoarthritis. Posterior lateral meniscus root tears (PLMRTs) also have been reported to increase anterior tibial translation and pivot shift in anterior cruciate ligament-deficient knees. Therefore, it is crucial to repair meniscal root tears when possible to restore knee joint loading and kinematics. Several techniques for repair of the PLMRT have been described. In this Technical Note, we describe our preferred technique for repair of PLMRT using an all-suture anchor. This technique is reproducible, does not need a tunnel, mitigates bungee effect of transtibial technique, and the anchor can easily be inserted on the footprint without a need for a guide.

Subacromial Balloon Spacer for Massive, Irreparable Rotator Cuff Tears Is Associated With Improved Shoulder Function and High Patient Satisfaction.

PURPOSE: To investigate associations between clinical and demographic parameters and Constant-Murley (CM) scores after subacromial balloon placement for massive, irreparable rotator cuff tears and to evaluate implant survival, shoulder function, and patient satisfaction. METHODS: We prospectively analyzed patients with rotator cuff tears deemed irreparable on preoperative magnetic resonance imaging for whom nonoperative therapy was unsuccessful and who underwent balloon placement from 2014 to 2017 with minimum 1-year follow-up. Shoulder function was assessed using the CM score and the 12-Item Short Form Health Survey. RESULTS: The study included 51 patients (22 women and 29 men) with a mean age at surgery of 63 years (range, 50-78 years). The mean follow-up period was 36 months (range, 24-56 months). The postoperative acromiohumeral interval and total preoperative CM score predicted the postoperative CM score at final follow-up. The implant survival rates were 92% at 6 and 12 months, 90% at 2 years, and 87% at 3 and 4 years. Five patients underwent reverse total shoulder arthroplasty, and 1 underwent latissimus dorsi tendon transfer. Postoperatively, mean CM scores (± standard deviation) improved for range of motion (from 11 ± 5.4 to 34 ± 6.8) and strength (from 13 ± 5.4 to 28 ± 12) (P < .01 for both). The total CM score improved from 27 ± 7.4 preoperatively to 77 ± 15 postoperatively (P < .01). The physical and mental component summary scores on the 12-Item Short Form Health Survey improved from 27 ± 5.0 to 51 ± 6.5 (P = .02) and from 44 ± 15 to 56 ± 8.0, respectively (P < .01). Thirty-eight patients reported excellent satisfaction, 8 were satisfied, and 5 were dissatisfied. Of the patients, 50 (98%) exceeded the minimal clinically important difference (≥10.4) and patient acceptable symptom state (≥44). CONCLUSIONS: At mean 3-year follow-up, subacromial balloon spacer placement for massive, irreparable rotator cuff tears was associated with a significant improvement in shoulder function, limited need for revision surgery, and high patient satisfaction. A greater postoperative acromiohumeral interval and lower preoperative CM score predicted a lower postoperative CM score at final follow-up. LEVEL OF EVIDENCE: Level IV, retrospective cohort study and treatment study.
