Combined arthroscopy and "mini-reconstruction" techniques in the acutely torn anterior cruciate ligament

A concept of the "knee at risk" has been discussed. Such knees with acute anterolateral rotatory instability require stabilization. The combination procedure of arthroscopy for diagnosis and treatment of internal derangement with an extra-articular reconstruction has been described. In a follow-up study of 69 cases so treated, objective results were 94 per cent acceptable, and subjective results were 93 per cent acceptable. There was no apparent difference either objectively or subjectively between 12 to 24 months and 24 to 65 months postoperatively in this series. The high incidence (80 per cent) of meniscal lesions in this series re-emphasizes the need for a high index of suspicion of internal derangement in acute knee ligament injuries.
