Outcome Measures

Primary Outcomes (3)

  • Knee range of motion (ROM)

    Goniometer measure range of motion (minimum 0, maximum 145)

    Change from baseline Knee range of motion (ROM) at 3 months, 6 months, and 12 months after surgery

  • Knee flexion

    Goniometer measure knee flexion (minimum 135, maximum 145)

    Change from baseline knee flexion at 3 months, 6 months, and 12 months after surgery

  • Knee extension

    Goniometer measure knee extension (minimum -10, maximum 0)

    Change from baseline knee extension at 3 months, 6 months, and 12 months after surgery

Secondary Outcomes (4)

  • Knee Society and Knee Society function score

    Change from baseline Knee Society and Knee Society function score at 3 months, 6 months, and 12 months after surgery

  • New patellar score

    Change from baseline new patellar score at 3 months, 6 months, and 12 months after surgery

  • Oxford knee score

    Change from baseline Oxford knee score 3 months, 6 months, and 12 months after surgery

  • Prevalence of anterior knee pain ,AKP

    Change from baseline Prevalence of anterior knee pain ,AKP 3 months, 6 months, and 12 months after surgery

Study Arms (2)

Complete contact

ACTIVE COMPARATOR
Procedure: Complete patellofemoral articular contact

Incomplete contact

ACTIVE COMPARATOR
Procedure: Incomplete patellofemoral articular contact

Interventions

The patellofemoral condition is in constant contact with the femoral trochlea when the knee is bent from 30 to 90 degrees during the No thumb test.

Complete contact

The patellofemoral condition is in no constant contact with the femoral trochlea when the knee is bent from 30 to 90 degrees during the No thumb test.

Incomplete contact
