Abstract

Case

A 26-year-old elite male swimmer presented with chronic, isolated, hallux metatarsophalangeal joint varus instability status post previous lateral collateral ligament repair. We report a novel surgical technique for revision first metatarsophalangeal joint (MTP-1) lateral collateral ligament reconstruction using soft tissue imbrication and augmentation with a degradable polycaprolactone-based polyurethane urea (PUUR) matrix. There is paucity in the literature describing the surgical management of revision lateral collateral ligament injury in these cases.

Conclusion

Our reconstruction technique using degradable PUUR matrix restores natural soft tissue elasticity, provides a scaffolding for neocollagenesis, is bioinert, and delivers a low-profile reconstruction allowing the patient to return to high level competition with excellent patient outcomes at one year follow up.

用聚氨酯尿素基质重建一名精英运动员的第一跖趾关节外侧副韧带：病例报告

病例一名 26 岁的精英男子游泳运动员在之前的外侧副韧带修复术后出现了慢性、孤立的跖趾关节屈曲不稳状态。我们报告了一种新颖的第一跖趾关节（MTP-1）外侧副韧带翻修重建手术技术，该技术使用软组织连接和可降解聚己内酯基聚氨酯尿素（PUUR）基质增强。结论：我们使用可降解聚己内酯基质的重建技术恢复了软组织的天然弹性，为新胶原蛋白的生成提供了支架，具有生物惰性，而且重建后的外型低调，使患者能够重返高水平比赛，并在一年的随访中取得了良好的疗效。
