These developments have renewed interest in organisational models capable of supporting coordinated, high-quality musculoskeletal care while maintaining clinical efficiency and professional sustainability. This structured narrative review evaluates contemporary organisational models of orthopaedic practice, with particular emphasis on structured group practice, within the Indian healthcare context. A structured narrative review was undertaken using PubMed as the primary database, supplemented by targeted Google Scholar searches and manual reference screening. Forty-five publications meeting predefined eligibility criteria were included in the final narrative synthesis. Evidence relating to orthopaedic practice organisation, subspecialisation, volume-outcome relationships, multidisciplinary care, clinical governance, registry participation, workforce wellbeing, health-system organisation, and practice sustainability was synthesised. The available literature suggests that structured group practice may facilitate subspecialty-focused care, multidisciplinary collaboration, standardisation of perioperative pathways, registry participation, continuous quality improvement, and equitable workload distribution. However, direct comparative evidence demonstrating superiority over well-organised solo or small-group practice remains limited, particularly in India. Many reported advantages appear to arise from effective evidence-based organisational processes rather than organisational size alone. The available evidence suggests that organisational models capable of supporting multidisciplinary care, clinical governance, and evidence-based organisational processes are increasingly important for contemporary orthopaedic practice. Structured group practice represents one context-dependent organisational approach that may be particularly relevant to urban India. The review identifies important evidence gaps, particularly the lack of comparative Indian studies, and highlights priorities for future research.</p>","PeriodicalId":16608,"journal":{"name":"Journal of Orthopaedic Surgery","volume":"34 2","pages":"10225536261476473"},"PeriodicalIF":1.6,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148678936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Local infiltration analgesia (LIA) using multimodal cocktail drugs injections has become an effective approach for perioperative pain control in UKA. However, most existing studies have focused on the use of cocktail drugs in total knee arthroplasty (TKA), whereas differences in their intraoperative application between UKA and TKA have rarely been reported.MethodsThis narrative review synthesizes literature identified from three databases. A comprehensive review of recent literature was conducted to summarize the different categories of cocktail drugs, their applications, efficacy, and evolving roles in UKA, and to compare their use with that in TKA.ResultsLocal injection of cocktail drugs, as an essential component of multimodal analgesia, has been widely applied during UKA. The cocktail drug approach provides synergistic advantages by combining multiple agents, resulting in enhanced analgesic and anti-inflammatory effects, prolonged duration of pain relief, and hemostatic benefits. At present, the primary method of administration involves intraoperative periarticular local infiltration. In most patients, postoperative pain scores and analgesic requirements during the early postoperative period, particularly within the 1-2 days after surgery, are lower after UKA than after TKA. Therefore, the formulations and dosages of cocktail drugs used in the two operations are not entirely identical.ConclusionsCocktail drug therapy is characterized by a simple administration procedure. Current evidence indicates that, for selected UKA patients, periarticular cocktail drugs injections can facilitate postoperative pain control and early functional recovery. Given the significant differences in surgical trauma, pain intensity, and tissue exposure between UKA and TKA, the direct application of TKA formulations to UKA should be approached with caution. However, UKA-specific studies remain limited, and further research is warranted to refine these protocols.</p>","PeriodicalId":16608,"journal":{"name":"Journal of Orthopaedic Surgery","volume":"34 2","pages":"10225536261451053"},"PeriodicalIF":1.6,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148421737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

WC patients (N = 4,101) were matched 1:5 with non-WC patients (N = 20,505) based on demographic and comorbidity characteristics.
