Abstract
Twenty four operations were reviewed in 23 patients to show a modified Roux-Goldthwait operation would improve the symptoms of chronic patella instability. This retrospective study used a questionnaire to record symptoms before and after surgery. The examination assessed joint hypermobility, patella tracking and stability, the Q and valgus angles of the knee. Apprehension test and assessment of patella tilt was also assessed. All patients underwent radiographic assessment. Twenty of 23 patients were improved by this procedure. Patella subluxation was reduced by 22%. Patella dislocation was reduced by 86%. The 3 unsuccessful cases had generalised joint laxity and may have been improved by the addition of a medial reefing procedure. There were no cases of tibial tuberosity numbness post operatively, patella tilt or failure of the transposed tendon. We showed that this procedure is effective, regardless of x-ray signs. We did observe a subjective increase in patellofemoral pain post operatively.
