Evidence of knee extensor dysfunction during sit-to-stand following distal femoral extension osteotomy and patellar tendon advancement in young adults with cerebral palsy: A pilot study

The functional deficit among DFEO + PTA participants may be due to patella baja decreasing the knee extensor moment arm, which concurs with the modeling prediction. The group differences may also be due to the non-DFEO + PTA group being slightly higher functioning. Future research is warranted to determine if optimizing patella position during a DFEO + PTA may improve unaided STS function without compromising gait improvements.
