Experience of Bone-Block Transfer of the Medial Head of the Gastrocnemius in Cases of PCL Insufficiency
1985
Three cases of old PCL insufficiency were treated by bone-block transfer of the medial head of the gastro-cnemius as presented by J. N. Insall in 1982. The mean follow-up time was twelve months. The results were evaluated following the scoring scale advocated by Lysholm and Gillquist. Case 1 was marked 92 points, case 2, 75 points and case 3, 70 points. The most improved were concerning instability and pain during gait. Static instability was not improved. The functional improvement of the knee is speculated to be due to the dynamic function of the medial head of the gastrocnemius which tends to reduce the upper tibia anterioly during gait and running.
