Task: Answer Verification
Input (English): Question: Do changes in patellofemoral alignment cause clinical impact after open-wedge high tibial osteotomy?
Answer: After open-wedge high tibial osteotomy, clinical results showed improvement, compared to pre-operative values. The patellar tilt and lateral patellar shift were not changed; however, descent of the patella was observed. Therefore, mild patellofemoral problems should not be a contraindication of the open-wedge high tibial osteotomy.
Output (English): no
