We report on 28 patients (47 knees) who were treated using the Lord's procedure. Overall results were evaluated by Hukubayashi's classification, X-ray evaluation and Q angle.
All cases were clinically evaluated as almost excellent or good. We then compared excellent cases with good ones in regard to degree of medialization and ventralization.
Results showed that the degree of medialization correlated with an improvement in X-ray evaluation and Q angle, but the degree of ventralization did not correlate.
Therefore, when performing the Lord's procedure, corrct medialization is more important than ventralization.
