The patients were divided into the acute lesion group and the chronic lesion group according to the time from first injury to surgery. The size of bone fragment was used to group the patients into the small and the medium sized fragment groups. All the patients underwent arthroscopic repairs using the transosseous sling-suture technique. Preoperative and postoperative evaluations including Rowe score, West Ontario Shoulder Instability Index (WOSI), Visual Analogue Scale (VAS) for pain scores, ROMs and number of dislocations were recorded. No significant differences were found in the comparisons of postoperative ROMs ang functional outcomes regarding between the small and the medium sized fragment groups.</p></div><div><h3>Results</h3><p>No dislocations occurred for both groups postoperatively.

Increase in MME occurs during the stance phase of the gait cycle, which is key for its expand. The knee adduction moment (KAM) represents the mechanical stress on the medial compartment; however, the relationship between the increase in MME and KAM is still unknown. Therefore, the present study aimed to investigate the relationship between MME during gait and KAM.</p></div><div><h3>Methods</h3><p>Twenty-one patients with medial knee osteoarthritis and 11 healthy middle-aged adults were recruited. Three-dimensional motion analysis system and ultrasonography were used to measure the KAM and MME in the stance phase. The increase in MME was identified as the difference in MME between the maximum and minimum (ΔMME). Patients with knee osteoarthritis performed two conditions as normal and toe-out gait. The difference in KAM and ΔMME between conditions were evaluated.</p></div><div><h3>Results</h3><p>ΔMME was correlated with the KAM second peak in normal gait of knee osteoarthritis patients (r = 0.51, p &lt; 0.05). Toe-out gait reduced the KAM second peak and the ΔMME, and these reductions were correlated (r = 0.50, p &lt; 0.05).</p></div><div><h3>Conclusions</h3><p>Toe-out gait immediately inhibited the expansion of MME associated with the KAM second peak.</p></div>","PeriodicalId":44283,"journal":{"name":"Asia-Pacific Journal of Sport Medicine Arthroscopy Rehabilitation and Technology","volume":"33 ","pages":"Pages 13-19"},"PeriodicalIF":2.1,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/dc/14/main.PMC10474330.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10149859","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}
