They were segregated into two groups matched for all demographic and pre-operative values: group A did not undergo debulking; group B underwent open debulking by a 15-number blade prior to UKA. [4]showed high percentages of laxity post debulking of MD-ACL, a finding which would not allow a surgeon to carry out a UKA after the debulking. The authors presume that this objective end point suggests adequate debulking, just enough to remove the impingement factor from the lateral femoral condyle, femoral notch and PCL, and consequently the symptoms associated with the impingement.
