Several conditions may require medial collateral ligament (MCL) surgery, especially when high physical demands are required. Thus, we described a technique for anatomical repair of distal MCL rupture using a distal anchor and MCL augmentation through Achilles tendon allograft with proximal bone block and interference screw. This procedure fixes an anchor distally at the tibia. Then, the ligament endings are sutured using a continuous simple-type technique. Subsequently, a low-radiated Achilles tendon allograft is attached proximally and fixed through an interference screw. Finally, the allograft is sutured using a continuous simple-type technique. Our anatomical MCL repair and augmentation allows a reinforced anatomical technique to control the valgus instability caused by MCL distal ruptures, considering the MCL axial traction and posterior oblique ligament fiber orientations.
几种情况可能需要内侧副韧带（MCL）手术，尤其是在对身体要求较高的情况下。因此，我们描述了一种使用远端锚钉进行MCL远端断裂解剖修复的技术，并通过带近端骨块和挤压螺钉的跟腱同种异体移植物进行MCL增强。该手术将一个锚钉远端固定在胫骨上。然后，使用连续单纯缝合法缝合韧带断端。随后，将低辐射的跟腱同种异体移植物近端附着并通过挤压螺钉固定。最后，使用连续单纯缝合法缝合同种异体移植物。考虑到MCL的轴向牵引力和后斜韧带纤维方向，我们的解剖学MCL修复和增强技术允许采用一种强化的解剖学技术来控制由MCL远端断裂引起的外翻不稳定。
