Reconstruction of anterior cruciate ligaments with bone-patellar tendon-bone and achilles tendon allografts.

Two hundred fourteen patients had anterior cruciate ligament (ACL) reconstructions performed with banked freeze-dried or frozen allografts using an arthroscopic-assisted technique. Of these, 181 patients were available for follow-up testing and examination. Minimum follow-up time was four years (average, 57 months).

The role of Na-hylan in reducing postsurgical tendon adhesions: Part 2.

Na-hylan, a chemically modified sodium hyaluronate jelly, was studied mechanically and histologically as a surgical device to diminish tendon adhesions in rabbit extensor hallucis longus tendons after severe surgical trauma. Na-hylan jelly of high viscoelastic properties was found to be highly effective in decreasing tendon adhesions. Na-hylan jelly of low viscoelastic properties was not effective in diminishing adhesion formation.
