There were 1 male and 2 females with the age of 81, 68, and 68 years old. The affected knee has varus or valgus deformity, with tibia-femoral angles of 169.7°, 203.3°, and 162.2°, respectively. The hip-knee-ankle angle (HKA), range of motion (ROM), knee society scoring system (KSS), and pain visual analogue scale (VAS) score were used to evaluate joint function and pain relief. Based on model bone, the thickness and bone bed area of the medial and lateral femoral condyle osteotomy blocks in FCSO were measured. During TKA in 12 patients, the range of osteotomy block movement was evaluated. By simplifying the upward and forward movement of the osteotomy block into a geometric model, the impact of movement on the flexion gap and external rotation of the prosthesis was calculated.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;After application of FCSO during TKA, the limb alignment and medial and lateral balance at extension and flexion positions were restored in 3 patients. Three patients were followed up 23, 11, and 3 months, respectively. Postoperative HKA, pain VAS score, KSS score, and ROM all showed significant improvement compared to preoperative levels. The maximum thickness of osteotomy blocks by MCSO and LCSO was 17 and 12 mm, respectively. The simple upward movement of the osteotomy block mainly affected the extension gap, and had little effect on the flexion gap and external rotation of the prosthesis. Moving the osteotomy block forward at the same time had a significant impact on the flexion gap and external rotation of the prosthesis, especially on LCSO. Mild forward movement leaded to a decrease in external rotation of more than 3°, which had a serious impact on the patellar trajectory.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;FCSO can effectively solve the problem of imbalance between the medial and lateral spaces during initial TKA, avoiding knee joint instability caused by excessive loosening and limiting the use of constrained condylar prosthesis. The distance for the downward movement of the osteotomy block in MCSO and LCSO was 3-5 mm and 6-8 mm, respectively, with 10-15 mm of space for forward movement and almost no space for backward movement. For MCSO, the upward and forward movement of the osteotomy block will increase the external rotation of the prosthesis, which is beneficial for improving the patellar trajectory and suitable for valgus knee. LCSO is suitable for varus knee, and the osteotomy block only slides vertically up and down wit","PeriodicalId":23979,"journal":{"name":"中国修复重建外科杂志","volume":"39 4","pages":"425-433"},"PeriodicalIF":0.0,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12011504/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144031598","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}

There were 13 males and 5 females with an average age of 28.3 years (range, 17-41 years). Causes of injury included 11 cases of direct violence injury, including 6 cases of traffic accident injury, 4 cases of sports injury, 1 case of falling injury; 7 cases of indirect violence injury, all sports injury. All patients had complete ACL rupture, including 15 acute injuries and 3 old injuries. The preoperative pivot shift test was grade Ⅱ in 9 cases and grade Ⅲ in 9 cases. All patients were treated with ACLR combined with modified Lemaire procedure. The International Knee Documentation Committee (IKDC) score and Lysholm score were used to evaluate the effectiveness before operation and at 3, 6, 12 months after operation. KT-2000 arthrometer was used to measure the anterior stability of the knee joint, and the difference between the healthy and affected sides was recorded.

There were 10 cases of acute injury and 21 cases of chronic injury. According to DeOrio and Cofield classification criteria, the degree of rotator cuff tear rated as medium-sized tears in 3 cases, large tears in 12 cases, and massive tears in 16 cases. Associated injuries included 5 cases of shoulder joint adhesions, 12 cases of subscapularis muscle tears, and 31 case of shoulder impingement syndromes. The shoulder range of motion (ROM) (forward flexion, abduction, lateral external rotation, lateral internal rotation) and pain/function scores [visual analogue scale (VAS) score, University of California Los Angeles (UCLA) shoulder score, Constant-Murley score] were recorded before operation and at last follow-up. MRI at last follow-up were taken to evaluate the rotator cuff healing and structural integrity.</p><p><strong>Results: </strong>All 31 surgeries were successfully completed with operation time ranging from 90 to 210 minutes (mean, 144 minutes). The 3-5 anchors (mean, 3.8 anchors) were used during operation. All incisions healed by first intention. All patients were followed up 12-29 months (mean, 18.5 months). At 3 months after operation, 2 cases developed joint adhesions, 3 had internal rotation limitations, and 2 experienced residual pain at the intertubercular groove, all resolved with conservative management. No Popeye deformity occurred during follow-up. At last follow-up, shoulder ROM (forward flexion, abduction, lateral external rotation, lateral internal rotation) and pain/function scores (VAS, UCLA, and Constant-Murley scores) showed significant improvements compared to preoperative values ( <i>P</i><0.05). At last follow-up, MRI evaluation showed that the rotator cuff healing rate reached 90.3% according to the Sugaya classification criteria. LHBT exhibited normal morphology, course, and continuity without dislocation. Surrounding synovial sheath showed no thickening or effusion.</p><p><strong>Conclusion: </strong>Arthroscopic double fixation and enhanced suture of LHBT <i>in situ</i> for repairing rotator cuff tear can significantly reduce shoulder joint pain, improve ROM, and achieve a high rotator cuff healing rate.</p>","PeriodicalId":23979,"journal":{"name":"中国修复重建外科杂志","volume":"39 4","pages":"451-456"},"PeriodicalIF":0.0,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12011503/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144034970","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}
