Purpose: Poor wound-healing and skin necrosis are serious but not unusual complications after total knee arthroplasty, and when skin or soft tissue necrosis occurs, reconstructions in the knee area need thin, pliable, tough skin flaps.
Methods: A 62-year-old man, who previously underwent multiple TKR operations due to recurrent infection, was transferred from another hospital after a gastrocnemius muscle rotation flap failed. We decided to treat the affected area with a reverse gracilis muscle flap. After confirming that the secondary pedicle was intact by Doppler sonography, muscle dissection was extended to the entry of the secondary pedicle. The proximal tendon of the gracilis muscle was transected, and the muscle was rotated 180° and placed at the recipient site.
Results: The aim is to report a case of reconstruction at the anterior knee using a reverse gracilis muscle flap that achieved an excellent final clinical result.
Conclusion: This case suggests that the indications for a reverse gracilis muscle flap could be broadened when other flaps are not available for knee prosthesis coverage.

Malignant mesenchymal tumors are a diverse group of aggressive cancers originating from mesenchymal cells in connective tissues such as bone, muscle, cartilage, and fat. These tumors often invade surrounding tissues and metastasize to distant organs, posing significant treatment challenges. Among them, malignant mesenchymal tumors located in the distal femur are particularly rare, with limited reports detailing effective surgical and functional reconstruction strategies following wide resection.

Background: Free functional muscle transfer (FFMT) for brachial plexus injury (BPI) requires adequate donor arterial flow for successful anastomosis. However, concomitant BPI and subclavian artery injury are not uncommon. Arteriovenous (AV) loop graft is one of the methods used to extend vessels to areas with vascular depletion.

Background: Facial palsy (FP) is a widespread condition affecting over 3 million people annually, with a complex etiology requiring tailored, multidisciplinary management. Despite advancements, there remains a lack of reliable, automated tools for objective pre- and postoperative assessment, limiting progress in treatment optimization. This study introduces the AI Research Metrics Model (CAARISMA ® ARMM) to evaluate FP severity and outcomes following microsurgical gracilis muscle transfer.

Proximal gracilis tear is a rare sports-related injury that can easily lead to misdiagnosis and underdiagnosis. Clinical manifestations are dominated by localized pain, tenderness, and dysfunction. Here, we report a therapy of proximal segmental tear of the gracilis and demonstrate its treatment process and clinical outcome.

Purpose: For the athlete, anterior Cruciate Ligament (ACL) rupture and its surgical management are often a turning point in their career. Success and time to return to sport are essential parameters for athletes and their support staff, so it is critical to understand the prognostic factors influencing return to sport after anterior cruciate ligament reconstruction (ACLR). The aim of this study was to determine the influence of hamstring muscle composition on muscle power following ACLR with autogenous hamstring grafts.
