Background
Despite its high incidence, anterior knee pain syndrome is the most neglected, the least known, and the most problematic pathological knee condition. It was related to the presence of patellofemoral malalignment and patellofemoral arthritis. In this study the clinical results of arthroscopic lateral release of the patella with radiofrequency ablation in patients with recalcitrant anterior knee pain unresponsive to conservative treatment were reported.
Patients and methods
Between 2007 and 2009, 13 consecutive patients with anterior knee pain associated with patellofemoral malalignment were treated by arthroscopic lateral release of the patella. Patients were followed up prospectively for at least 1 year from surgery.
Results
The mean Feller patellofemoral score increased from 9 preoperatively to 27.5 at the final follow-up. There was significant relief from patellofemoral pain postoperatively compared with before operation.
Conclusion
Arthroscopic lateral release of the patella with radiofrequency ablation is effective in relieving pain and in correction of patellar maltracking with decreased loading of the lateral patella/trochlea.
