Arthroscopic roofplasty: a method for correcting an extension deficit caused by roof impingement of an anterior cruciate ligament graft.
نویسنده
چکیده
Intercondylar roof impingement should be suspected in any patient having difficulty regaining knee extension following an anterior cruciate ligament (ACL) reconstruction. An arthroscopically performed roofplasty can eliminate the clinical complaints. The extent of bone removal can be planned from studying a lateral radiograph taken with the knee in terminal extension. Extension exercises or passive extension devices should not be used in patients with extension deficits caused by roof impingement because they may further damage the graft.

Arthroscopic findings associated with roof impingement of an anterior cruciate ligament graft.
Nineteen patients with roof impingement of an anterior cruciate ligament graft had their grafts inspected during second-look arthroscopy. The diagnosis of roof impingement was suspected from the clinical findings of an effusion, extension deficit, recurrent instability, or anterior knee pain. The diagnosis was confirmed when a portion of the tibial tunnel was anterior to the tibial intersection...
متن کاملQuadriceps load aggravates and roofplasty mitigates active impingement of anterior cruciate ligament grafts against the intercondylar roof.
Because of the complications of impingement of anterior cruciate ligament grafts on the intercondylar roof and because current surgical procedures locate the tibial tunnel such that impingement is avoided during passive but not active extension, the objectives of this study were to determine if (a) active extension precipitates and aggravates roof impingement, and (b) a roofplasty mitigates the...
متن کاملKnee extension and its relationship to the slope of the intercondylar roof. Implications for positioning the tibial tunnel in anterior cruciate ligament reconstructions.
This study determined that knee extension (range, -30 degrees to 2 degrees) and the slope of the intercondylar roof (range, 26 degrees to 46 degrees) vary widely between knees in both men and women. We found a weak relationship between knee extension and the slope of the intercondylar roof (r2 = 0.207); therefore, roof angle cannot be predicted by clinically measuring knee extension. CLINICAL R...
متن کاملContact pressure and tension in anterior cruciate ligament grafts subjected to roof impingement during passive extension.
Contact between an anterior cruciate ligament graft and the intercondylar roof has been termed roof impingement. Grafts with impingement sustain permanent damage, and if the injury is extensive enough, then the graft may fail, causing recurrent instability. This study evaluated two mechanical factors that could be responsible for the graft injury associated with roof impingement: an increase in...
متن کاملCheckpoints for judging tunnel and anterior cruciate ligament graft placement.
This article examines how the relationship between sagittal and coronal anatomy, anterior cruciate ligament (ACL) graft dimensions, and tibial and femoral tunnel placement affects the posterior cruciate ligament (PCL) and roof impingement, and their undesirable clinical consequences of motion loss and instability. Based on these interrelationships, a variety of checkpoints are defined that can ...
