Preliminary experience with a method of quadricepsplasty in recurrent subluxation of the patella
R Madigan, HA Wissinger and WF Donaldson
Nineteen knees were treated for recurrent subluxation or dislocation of the
patella by lateral and distal transfer of the vastus medialis with or
without release of the lateral retinaculum. Fifty-eight per cent has good
or excellent and 42 per cent had poor results after a mean follow-up of
twenty-nine months. The factors that predisposed to failure were genu
valgum greater than 15 degrees and, to a lesser extent, palpable synovitis
associated with symptomatic chondromalacia patellae.
