This study was undertaken to generate and validate a murine model of knee joint trauma following noninvasive controlled injurious compression in vivo.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The right knees of 8\u2010week\u2010old mice were placed in a hyperflexed position and subjected to compressive joint loading at 1 of 3 peak forces (3N, 6N, or 9N) for 60 cycles in a single loading period and harvested on days 5, 9, and 14 after loading (n = 3\u20135 for each time point and for each loading). The left knees were not loaded and were used as the contralateral control. Histologic, immunohistochemical, and enzyme\u2010linked immunosorbent assay analyses were performed to evaluate acute pathologic features in chondrocyte viability, cartilage matrix metabolism, synovial reaction, and serum cartilage oligomeric matrix protein (COMP) levels.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Acute joint pathology was associated with increased injurious loads. All loading regimens induced chondrocyte apoptosis, cartilage matrix degradation, disruption of cartilage collagen fibril arrangement, and increased levels of serum COMP. We also observed that 6N loading induced mild synovitis by day 5, whereas at 9N, with tearing of the anterior cruciate ligament, severe posttraumatic synovitis and ectopic cartilage formation were observed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>We have established a murine model of knee joint trauma with different degrees of overloading in vivo. Our results suggest that immediate therapies particularly targeted to apoptosis and synovial cell proliferation could affect the acute posttraumatic reaction to potentially limit chronic consequences and OA.<\/jats:p><\/jats:sec>","DOI":"10.1002\/art.38375","type":"journal-article","created":{"date-parts":[[2014,1,27]],"date-time":"2014-01-27T14:22:01Z","timestamp":1390832521000},"page":"1256-1265","source":"Crossref","is-referenced-by-count":60,"title":["Early Response of Mouse Joint Tissue to Noninvasive Knee Injury Suggests Treatment Targets"],"prefix":"10.1002","volume":"66","author":[{"given":"P.","family":"Wu","sequence":"first","affiliation":[{"name":"Washington University School of Medicine St. Louis Missouri"},{"name":"First Affiliated Hospital of Sun Yat\u2010sen University Guangzhou China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N.","family":"Holguin","sequence":"additional","affiliation":[{"name":"Washington University School of Medicine St. Louis Missouri"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.
