We present the results of the Spanish right-to-left shunt (RLSh) multicenter study. Methods-Four hundred eighty-six patients with cryptogenic stoke were included at 17 participating hospitals. Patients were examined by contrast transcranial Doppler methods at baseline. The magnitude of RLSh was quantified during the Valsalva maneuver. Transthoracic and/or transesophageal echocardiography, computed tomography scan, or magnetic resonance imaging was performed. Functional outcome and stroke recurrence were evaluated at 3 months and yearly thereafter. The independent relation between RLSh magnitude and stroke recurrence was analyzed by logistic-regression analysis in the whole group and in the younger subgroup (Ͻ55 years).

The same tibio-femoral components were used in all knees. The cohorts were demographically similar. The clinical outcome and the patello-femoral revision rates were the same in the two cohorts. Analgesia was required for anterior knee pain in one patient with replacement and in one without. In the replacement group patello-femoral survival on a best-case scenario was 100% at 10 years, and on a worst-case scenario 96%; one of the nonreplaced patellae had been resurfaced for pain by 10 years. In view of the satisfactory and similar outcomes with and without replacement the authors suggest that an appropriate design for the prosthetic trochlea, rather than the replacement or otherwise of the patella, is the main determinant of patello-femoral outcome in total knee reconstruction. Thus patella replacement may be optional. Desirable trochlea design features are described.

The same tibiofemoral components were used in all knees. The cohorts were demographically similar. A total of 124 patellae were treated by replacement, and 143 were treated without replacement. The clinical outcome and the patellofemoral revision rates were the same in the 2 cohorts: 1 patient required analgesia for anterior knee pain after replacement, and 1 without replacement required patellar replacement for pain. In the replaced group, patellofemoral survival on a best-case scenario was 100% at 10 years; on a worst-case scenario, 96%. One of the unreplaced patellae had been resurfaced for pain by 10 years. In view of the satisfactory and similar outcomes with and without replacement, we suggest that an appropriate design for the prosthetic trochlea, rather than the replacement or otherwise of the patella, is the main determinant of patellofemoral outcome in total knee arthroplasty. Patella replacement may be optional. Desirable trochlea design features are described.
