An arthroscopic method for lateral release of subluxating or dislocating patella.


Arthroscopically controlled lateral release for subluxating and dislocating patellae was reviewed in 93 knees (79 patients) at an average of 48.7 months follow-up. Of the patients, 92 % reported significant subjective improvement. Eighty-nine per cent of males and 69% of females were rated good or excellent by objective criteria. Failure to maintain good quadriceps muscle strength was the major reason for fair and poor results. Of 14 knees with dislocations, none had a recurrence after surgery. Patellar shaving was not done in any of the knees. The results of lateral release did not correlate with the severity of chondromalacia patellae. Complications and morbidity were significantly reduced by this outpatient procedure. Experience in endoscopic techniques is an important prerequisite. In the properly selected and motivated patient, this procedure offers an effective alternative to major patellar realignment procedures.
