To The Editor:The otherwise excellent article, "Comparison of the Vastus-Splitting
and Median Parapatellar Approaches for Primary Total Knee Arthroplasty: A
Prospective, Randomized Study. Surgical Technique" (2007;89 Suppl 2 Part
1:80-92), by Kelly et al., was marred by an error in the legend to Figure 1.
The axial radiograph of the knee was mislabeled as "a Merchant
radiograph of the patella."The shape and appearance of the dista part of the femur on the radiograph
demonstrates that it is really a Settegast view. This technique requires the
knee to be acutely flexed well beyond 90°, drawing the patella, which
might otherwise be severely subluxated laterally at the trochlear level, into
the intercondylar space to articulate with the distal, or weight-bearing,
surface of the femoral condyles.
