Abstract

To discuss a new technique about reconstruction of medial collateral ligament (MCL) with double bundle allograft and to evaluate the short-term clinical efficacy. All 53 patients who suffered from valgus instability of the knee were selected. All cases were diagnosed of MCL injury because the medial gap of the knee widened more than 5 mm compared with collateral knee by the stress X-ray, MRI displayed discontinuity of MCL and valgus stress test was positive. All patients were accepted arthroscopic evaluation through inferomedial and inferolateral arthroscopy portal incisions to ascertain whether there were intra-articular injuries. An 8 cm incision was made from 1 cm superior adductor tubercle to 5 cm proximal medial tibia joint line in a longitudinal fashion. The anterior tibia insertion was defined as 15 mm lateral from the medial tibia edge and 45 mm under the medial tibia joint line. The posterior tibia insertion was defined as 15 mm lateral from the medial tibia edge and 20 mm under the medial tibia joint line. We used 5 mm or 6 mm reamer to drill the tibia tunnel along with guide pin, and then drill the femur tunnel with 6 mm or 7 mm drill in the top of the adductor tubercle about 25 mm or 30 mm length. The allograft was ...Continue Reading

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
