Then V-Y quadricepsplasty was done which allowed full flexion of knee without dislocation of patella (Fig.
In our case, we have done proximal realignment surgery which includes lateral release and medial plication and in addition to this we have done V-Y quadricepsplasty to address quadriceps contracture.
In habitual dislocation of the patella, if full flexion is not possible by keeping patella in trochlea, quadriceps contracture should be considered and in these cases, the addition of V-Y quadricepsplasty to the proximal realignment surgery (lateral release and medial plication) will provide excellent result.
The traditional Thompson quadricepsplasty, which has a history of more than 50 years, is called lysis of the extensor mechanism, but serious surgical trauma has remained.
The results of quadricepsplasty on knee motion following femoral fractures.
Examples of proximal procedures include the Madigan quadricepsplasty, arthroscopic medial imbrication, and MPFL reconstruction.
Proximal quadricepsplasty involves a release of tight lateral structures and advancement of the VMO insertion distally and laterally on the patellar surface.
Arthroscopic medial reefing is a slight deviation from the quadricepsplasty procedure as re-tensioning of the medial structures remains the same goal.
As emphasized by Insall and colleagues, (33) in 1972, and Insall, (43) in 1982, the operation is not a capsular procedure but rather a quadricepsplasty
