Advantages and Limitations

Advantages

A single-stage procedure can be performed.

Addressing all the problems during the same procedure allows the surgeon to balance the effect of each technique over the patellar tracking and stability.

Adding trochleoplasty to the procedure in patients with a dysplastic trochlea (Dejour type B, C, or D) helps normalize the patellar tracking and likely reduces the redislocation rate.

Limitations

Aggressive procedures can lead to more scar tissue. Physical therapy should be initiated on the first day postoperatively.

A longer surgical time is required.

The literature still lacks outcome studies reporting results for the combined technique.
