Reactions to Vicryl have rarely been reported in the literature. Moreover, a reaction that begins less than 24 hours postoperatively is even rarer. We present a case of Vicryl hypersensitivity that developed within 24 hours at the site of the wounds following arthroscopic anterior cruciate ligament (ACL) reconstruction and meniscal repair. A 32-year-old male patient underwent arthroscopic ACL reconstruction and lateral meniscus repair due to an injury on the soccer field. On postoperative day one, erythema and edema were observed around the wounds, and the patient complained of itching and tenderness in the same areas. Despite local and systemic medication for infection, contact dermatitis, and antiseptic allergy, no improvement was noted. Vicryl hypersensitivity was suspected. Vicryl was removed, and a polydioxanone suture (PDS) was used instead, resulting in clinical improvement for the patient. In patients presenting with erythema, edema, blistering, itching, and tenderness around the wound, Vicryl hypersensitivity as a differential diagnosis can be considered after ruling out common causes. Hypersensitivity tests may be performed in suspected cases.
