Any here have or know of someone who had a problem with the bioabsorbable interference screws not re-absorbing, or taking a longer than normal time to reabsorb? And, if so, were there any associated symptoms with it? I'm nearing two years post op and having some issues with my post-op ACL knee and recently had an MRI. The screw in my tibia has resolved, but the one in my femur is still there and shows what appears to be inflammation/fluid around a large area of the bone and the screw. The screws were used to hold my ACL graft in place. Ortho told me the inflammation could indicate an allergy to the screw. The fact that it's still there almost 2 years later, seemed to concern him. The MRI also showed effusion (fluid/inflammation) in other areas within my knee, but no other issues going on, everything in tact. Not sure why one of my screws re-absorbed and the other hasn't, doesn't seem to make sense either. But, I guess could happen??... any one ever heard of this before??
