[Spontaneous fracture of the tibia after replacement of the anterior cruciate ligament with absorbable interference screws. A case report and review of the literature].

We report a granulomatous inflammatory reaction after administration of absorbable interference-fit screws for fixation of patellar-tendon-autograft in anterior-cruciate-ligament reconstruction, leading to spontaneous fracture of the tibia. Radiological evaluation demonstrated osteolytic lesions at the interference-fit screw insertion-site. Histological findings included a sterile inflammatory reaction and giant-cell formation.
