Recent trends indicate a shift towards nonoperative treatment, even for severe Rockwood type V injuries, which traditionally required surgery. Despite this shift, some patients may still benefit from surgical stabilisation, particularly if significant pain and disability persist. Modern surgical techniques focus on cortical button systems and restoration of the coracoclavicular ligaments, emphasising the importance of the posterosuperior acromioclavicular capsuloligamentous complex in managing horizontal instability. Clavicular hook plates offer rigid stability but present risks, such as damage to the subacromial structures and acromial erosion. Although anatomical repair techniques have gained prominence due to their biomechanical advantages and have been endorsed by international societies, non-anatomic methods may also provide acceptable outcomes with lower costs. The use of tendon grafts in chronic ACJ instability has shown promise, although evidence for their use in acute cases remains limited. This review discusses various treatment strategies, including operative and nonoperative management, focusing on patient outcomes, complication rates, and return-to-sport scenarios.

Given the challenges in diagnosing LMPRTs and the biomechanical significance of the lateral meniscus, this research highlights the potential long-term impact of untreated root tears. A prospective analysis was conducted on seven patients with chronic LMPRTs and suspected LFC lesions, identified through clinical symptoms, history of ACL injuries and magnetic resonance imaging (MRI) findings. The presence of LMPRTs was confirmed via arthroscopy, and the lesions were classified using the LaPrade Classification. The patients underwent various surgical interventions, including ACL reconstruction with lateral tenodesis and meniscus repair. All seven cases demonstrated a significant association between chronic LMPRTs and chondral/osteochondral lesions of the LFC. The lesions were consistently located in the posterolateral compartment, with MRI indicating subchondral bone oedema and cartilage thinning. Surgical findings confirmed Type II posterior root tears in all patients, with subsequent repair. The study suggests that chronic LMPRTs, especially in the context of ACL injuries, may contribute to the development of chondral or osteochondral lesions in the LFC. This association underscores the importance of early diagnosis and treatment of meniscus root tears to prevent long-term joint degeneration.

However, the evidence of effectiveness is limited, possibly due to the heterogeneity of parameters. This scoping review aims to summarise existing evidence, clarify the mechanism and effect of cryotherapy on swelling after total knee arthroplasty, and analyze various parameters, providing evidence for clinical practice and future research.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>A literature search was performed on PubMed to include articles which reported on the cryotherapy impacts postoperative swelling after total knee arthroplasty. Snowballing research was used to obtain more sources.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>A total of 69 studies were identified from the initial research, of which 40 articles were included for the full text analysis. Cryotherapy primarily acts on swelling by reducing haemorrhage and inflammatory responses. The level of evidence for the effectiveness of cryotherapy is low, and there is no standard in its parameters. The initiation of cryotherapy is increasingly recommended to start immediately after surgery. The selection of treatment temperature needs to balance efficacy and safety, but measuring intra-articular temperature presents obstacles, making skin temperature a more feasible option. However, it is unclear how to achieve the desired skin temperature by setting a combination of treatment temperature, pressure and duration. When determining the length of the interval, particular attention should be paid to the changes in blood perfusion levels during the rewarming phase, as evidence suggests that skin temperature during rewarming may not accurately reflect the actual level of blood perfusion. The location and duration of cryotherapy can be preliminarily determined through existing evidence and mechanism analysis.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>Some cryotherapy parameters are supported by evidence and can be practiced in clinical practice. It should be noted that skin temperature has limitations as an observation indicator during the rewarming stage, and the frequency of cold therapy needs further research to determine.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Level of Evidence</h3>\u0000 \u0000 <p>Level IV.</p>\u0000 </section>\u0000 </div>","PeriodicalId":36909,"journal":{"name":"Journal of Experimental Orthopaedics","volume":"12 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/jeo2.70197","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143571332","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All patients were followed up for 30 months. Psychological factors of anxiety, depression, kinesiophobia and catastrophizing were assessed by means of self-administered Hospital Anxiety and Depression Subscale (HADS), Tampa Scale for Kinesiophobia (TSK) and Pain Catastrophizing Scale (PCS) questionnaires one week prior to surgery. Clinical outcomes were evaluated preoperatively and at 3, 6, 9, 12, 15 and 30 months postoperatively using the Kujala score, the Western Ontario Meniscal Evaluation Tool (WOMET) score, the International Knee Documentation Committee (IKDC) score and the Tegner Activity Scale. Participants were classified as pathological or non-pathological scores for each psychological parameter in accordance with the cut-off point proposed by the authors of each questionnaire. The interaction between clinical outcome's evolution and pathological scores was analysed using two-way ANOVA tests with Greenhouse–Geisser correction to avoid non-sphericity errors.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>Forty-one cases were included (mean age 37.1 years old, 41% female).
