ABSTRACT

PURPOSE: This literature review aims to present evidence-based clinical recommendations for the eight most debated topics related to perioperative management in total knee arthroplasty: counselling, prehabilitation, transfusion risk, tranexamic acid, drainage, analgesia, urinary catheter and compression stockings. METHODS: A multidisciplinary team conducted a systematic review on these topics. The study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for the literature review and result presentation. The research encompassed articles from 1 January 2009 to 28 February 2023, retrieved through the MEDLINE database via PubMed, Embase database and Cochrane Library. RESULTS: Forty-five articles were selected. Preoperative counselling has limited evidence for its impact on postoperative outcomes; yet, it can help alleviate surgery-related anxiety and manage postoperative symptoms. Prehabilitation can also prepare patients for surgery, reducing hospital stays and improving postsurgery functionality. Numerous studies suggest that preoperative Hb levels are independently linked to transfusion risk, with a recommended level of 13 g/dL. Combining intravenous and local tranexamic acid administration is strongly advised to reduce perioperative blood loss, while drainage after primary total knee arthroplasty offers no functional advantages. Employing a multimodal analgesia approach yields better results with reduced opioid usage. Indwelling urinary catheters provide no benefit and avoiding them can lower the risk of urinary tract infections. As for compression stockings, there is insufficient evidence in the literature to support their efficacy in preventing venous thromboembolism. CONCLUSION: The best-track protocol has demonstrated its efficacy in reducing hospitalisation time and perioperative/postoperative complications. It is success relies on a collaborative, resource-adaptive approach led by a multidisciplinary team. Both patients and hospitals benefit from this approach, as it enhances care quality and lowers costs. Several studies have highlighted the significance of a patient-centred approach in achieving high-quality care. Creating a novel treatment protocol could be a prospective goal in the near future. LEVEL OF EVIDENCE: Level III.

ABSTRACT

PURPOSE: This study's goal is to propose a straightforward classification system based on the MEI (Meniscal Extrusion Index), a measure of meniscal extrusion, that relates to various meniscal lesion patterns and has clinical and biomechanical significance. The study's secondary goal is to determine whether the standard 3 mm meniscal extrusion parameter still has value by correlating the MEI with it. METHODS: 1350 knee MRIs that were performed over the course of 2 years made up the study cohort. Following the application of inclusion and exclusion criteria, 200 of those patients were qualified to participate in the study. All the measurements examined for this study underwent an interobserver reliability test. RESULTS: In the 1350 MRIs that were examined for this study, meniscal extrusion of any grade was present 18.9% of the time. The use of the MEI revealed three groups of patients: those with a MEI < 20%, who are likely para-physiological; those with a MEY between 20% and 40%, who are in a grey area; and those with a MEY > 40%, who have lesions that are impairing the proper meniscal function. According to the authors' findings, the percentage of meniscal extrusion did not correlate with the finite number (3 mm), making the 3 mm parameter an unreliable evaluation method. CONCLUSIONS: This study is clinically relevant, because it proposes a simple and reproducible classification of meniscal extrusion that may aid in evaluating the severity of an extrusion and help in the diagnosis of lesions that might be difficult to identify on MRI. LEVEL OF EVIDENCE: Level IV.

ABSTRACT

PURPOSE: This study aims to find a correlation between bone marrow lesions (BMLs) in knee MRI and pathologies of joint structures. In addition, according to the six-letter system classification, the authors analyzed a potential association between the area affected by BMLs and the specific type of joint lesion. METHODS: The authors screened all the knee MRIs performed in the investigation center between 2017 and 2018 to identify the presence of BMLs. The lesions were then categorized following the "six-letter system". The authors searched the presence of associated meniscal, chondral or ligamentous lesions. Finally, the authors researched a correlation between the lesion type described by the six-letter system classification and the associated lesions. RESULTS: MRI exams of 4000 patients were studied, identifying 666 BMLs. The associated lesions were collected for all patients, resulting in an overall prevalence of related lesions in almost 90% of patients. The authors found a statistical significance for type TLD (Tibia-Lateral-Articular) and ACL rupture. The study suggests a strong positive correlation between type E (Edge) and meniscal fracture or extrusion. CONCLUSION: BMLs in the knee are associated in 90% of cases with a radiological sign of related injury to the joint structures. The six-letter system of BMLs type TLD can be considered a sign of ACL rupture and type E as a high suspicious sign for meniscal extrusion. Those very typical BML patterns can help the clinician in the diagnosis of ACL tears and meniscal extrusion. Furthermore, the presence of a BML must be, for the clinician, a high suspicious sign of joint-related injuries. LEVEL OF EVIDENCE: Level 1.

ABSTRACT

PURPOSE: The aim of this study was to propose and validate a new six-item topographical classification of knee bone marrow lesions in coronal MRI images, to provide an easy-to-use aid to describe their location in a more reproducible and accurate way. METHODS: This study was conducted in four phases. The first was to do a literature search for methods of describing bone marrow lesions in MRI of the knee. The second was creation of a six-area topographic classification of bone marrow lesions in coronal MRI of the knee. The third phase was selection of cases with bone marrow lesions on knee MRI performed in a single hospital between January of 2017 and December of 2018. The fourth phase was categorization of the bone marrow lesions' location according to the new proposed classification by three independent examiners, two orthopedic surgeons and one radiologist. Patient's demographic data and associated lesions were collected. The inter-observer and intra-observer reliability of the proposed classification was then calculated. RESULTS: MRI examination of 4000 patients were studied and in 520 patients a total of 666 bone marrow lesions were identified and their location classified using the new system. The inter-observer and intra-observer reliability analysis found a Fleiss' Kappa value of 0.96 (0.95-0.97) and 0.97 (0.96-0.97), respectively, confirming the high reproducibility of the proposed classification. CONCLUSIONS: The proposed six-location classification of bone marrow lesions is highly reproducible and can help researchers develop studies and share information in a more accurate and reliable way. The correct classification of bone marrow lesions can lead to a more accurate description of this pathology and help clinicians to propose appropriate therapies for this group of patients.

ABSTRACT

BACKGROUND: The Zimmer Trabecular Metal Total Ankle Replacement (Zimmer TM TAR) is a recent ankle arthroplasty approved for use in the United States and Europe. Many of the studies reporting the results of this implant are provided by surgeons involved at least in the initial design of the implant under study. The aim of this study is to describe the early clinical and radiological outcomes in patients who underwent this procedure performed by non-designer surgeons. METHODS: A total of thirty consecutive patients underwent total ankle replacement with a Zimmer TM TAR surgery between July 2013 to January 2016.All clinical assessments were collected pre- and post-operatively with minimum follow-up of 12 months for each patient using the American Orthopedic Foot and Ankle (AOFAS) score, the Foot Function Index (FFI) and a visual analogue scale (VAS) for pain. Radiographic outcomes included ankle orientation assessed with angle "α","ß" and "γ" according to Wood. Furthermore, the anteroposterior offset ratio was measured in weight-bearing lateral ankle radiographs at the last follow-up. RESULTS: The mean preoperative FFI-pain (FFI-P) value was 53.67, the FFI-disability (FFI-D) was 64.19. At the last follow-up visit, the FFI-P and FFI-D was 16.95 and 20.76 respectively (p<0.01 for the both scales). Preoperatively, the mean VAS for pain and AOFAS score was 7.81 and 40.95 respectively, and at the last follow-up 2.29 and 86.38 (p<0.01 for the both scales). The mean angle calculated using Wood and Deakin's method were "α"= 89.02°, "ß"= 85.11 and "γ"= 27.54 post-operatively. At the last follow-up the same values were respectively 89.43, 85.18 and 29.94. At the last follow-up, the mean offset ratio was 0.06 (range 0.003/-0.17). CONCLUSIONS: These early results show high levels of patient satisfaction, and we are encouraged to continue with lateral approach total ankle arthroplasty.
