Brief Summary:
To evaluate the knee functionality, screw integrity, graft integrity, cartilage effect, and bony ingrowth in patients treated with the CALAXO screw and MILAGRO screw two years after ACL reconstruction.

Condition or disease
Rupture of Anterior Cruciate Ligament

Detailed Description:
This study will combine the use of survey response, MRI, and x-rays of the knees in Dr. Spindler's ACL reconstructed patients in order to examine long term healing of two types of bioabsorbable screw. We will use a 2-4 yr time point to look at patient reported symptoms of pain and swelling from the surveys and use the x-rays and MRIs to look at absorption of the screw, healing of the graft, and body reactions to the screw.
