Outcome Measures

Primary Outcomes (1)

  • Kellgren-Lawrence Grading Scale

    Using Magnetic Resonance Imaging (MRI) examination, and based on the images of bilateral knee joint, grade by Kellgren-Lawrence Grading Scale. Kellgren-Lawrence Grading Scale is a method of classifying the severity of knee osteoarthritis (OA). Grade 0: No radiographic features of osteoarthritis; Grade 1: Possible joint space narrowing (normal joint space is at least 2 mm at the superior acetabulum) and osteophyte formation; Grade 2: Definite osteophyte formation with possible joint space narrowing; Grade 3: Multiple osteophytes, definite joint space narrowing, sclerosis and possible bony deformity; Grade 4: Large osteophytes, marked joint space narrowing, severe sclerosis and definite bony deformity.

    12 months

Secondary Outcomes (4)

  • Assessment of Preoperative Cartilage Defect Severity (AMADEUS)

    12 months

  • Lysholm scoring

    12 months

  • The international knee documentation committee (IKDC) knee evaluation form

    12 months

  • Visual Analogue Scale/Score(VAS)

    12 months
