Tibial and Pretibial Cyst Formation After Anterior Cruciate Ligament Reconstruction With Bioabsorbable Interference Screw Fixation

Bio-interference screw cyst formation in anterior cruciate ligament reconstruction—10-year follow up

“…Two patients did develop new cyst formation from the 7 to 10 year scan, which confirms there is still biological activity taking place between these periods. Cyst formation is well described [16], with a number of postulated theories, such as a local foreign body reaction, along with the more conventional communication to the joint [17]. There are no previous 10 year 4-strand hamstrings MRI studies, which have reported cyst formation at this late stage.…”

Distant migration of a bioabsorbable implant in the shoulder

“…Similar findings of delayed resorption have been noted in the knee. 5,9 This patient clearly had progressive articular damage during the course of her treatment. The circumstances of this case do not allow one to assess whether the damage was due to the loose bioabsorbable material as has been suggested by others, 8 although the marked progression in the arthritic changes despite the absence of further instability suggest perhaps the bioimplant.…”

Inflammatory Response with Osteolysis Related to a Bioabsorbable Anchor in the Finger: A Case Report

“…In the literature, the reported rate of a clinically significant inflammatory reaction to bioabsorbable implants ranged from none to 47% [3,6,8,18,22]. The first generation of bioabsorbable implants consisted of polyglycolic acid and was found to rapidly degrade and cause an inflammatory reaction [3].…”
