Brief Summary:
The purpose of this study is to evaluate the efficacy and safety of adding CARTISTEM®(allogenic umbilical cord blood-derived stem cell product) on microfracture, a currently standard treatment for OLT, in patients with talar chondral or osteochondral defect.

Condition or disease Intervention/treatment Phase
Chondral or Osteochondral Lesion of Talus Biological: CARTISTEM® Procedure: Microfracture Phase 3

Layout table for study information
Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 102 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: A multicenter, Single-blinded, Stratified randomized
Masking: Double (Participant, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Multi-center, Single-blind, Randomized, Phase III Clinical Trial to Evaluate the Efficacy and Safety of Adding CARTISTEM® on Microfracture in Patients With Talar Chondral or Osteochondral Defect
Actual Study Start Date : March 3, 2020
Estimated Primary Completion Date : June 2022
Estimated Study Completion Date : June 2022

Arm Intervention/treatment
Experimental: Microfracture + CARTISTEM®
CARTISTEM® is added on the lesion as a single dose of 500 ㎕/㎠ according to the defect size after arthroscopic curettage and microfracture.
Biological: CARTISTEM®

*Stratified randomization by lesion size below 1.5㎠ or more than 1.5㎠

  1. Procedure: Microfracture
  2. Biological: CARTISTEM®(Human Umbilical Cord Blood-derived Mesenchymal Stem Cell product)

Active Comparator: Microfracture
Standard treatment of arthroscopic curettage and microfracture is performed for cartilage defect.
Procedure: Microfracture

*Stratified randomization by lesion size below 1.5㎠ or more than 1.5㎠

1. Procedure: Microfracture

Primary Outcome Measures :
  1. ICRS-Cartilage Repair Assessment Total Score [ Time Frame: Week 48 ]

    Arthroscopic evaluation of articular cartilage repair

    : The score range from 12(normal) to 1(severely abnormal) where lower scores indicate more severity of injury

Secondary Outcome Measures :
  1. ICRS-Cartilage Repair Assessment Overall Grade [ Time Frame: Week 48 ]
    The grades range from 1(normal) to 4 (severely abnormal) where lower grades indicate more complete repair

  2. Improvement degree of Cartilage Repair by MRI [ Time Frame: Week 0 and 48 ]

    Changes in MOCART(Magnetic resonance Observation of Cartilage Repair Tissue) score

    : MOCART score is a 9-part and 29-item scoring system, also resulting in a find cartilage repair tissue score between 0 and 100 points. 100 points represent the best imaginable score

  3. Degree of Functional improvement in FAOS(Foot & Ankle Outcome Score) [ Time Frame: Week 0, 24 and 48 ]
    : FAOS consists in 42 items that cover 5 dimensions (symptoms, pain, activities of daily living, sport and recreation activities, and quality of life. Raw scores of each sub-scales results of the sum of each items. A normalized score (100 indicationg no symptoms and 0 indicating extreame sysmptoms) is calculated for each subscale

  4. Degree of Functional improvement in AOFAS(The American Orthopaedic Foot & Ankle Score) [ Time Frame: Week 0, 24 and 48 ]
    : AOFAS consists in 9 items that can be divided into 3 sub-scales (pain, function and alignment). 100 points of 1 to 100 represent no symptoms or impairments

  5. Degree of Functional improvement in Tegner activity score [ Time Frame: Week 0, 24 and 48 ]
    : Tegner activity represents the highest level of activity on scale of 0 to 10 that you are able to participate in currently . The higher values represent a better outcome

  6. Degree of Quality of Life improvement in SF-36(Short Form Health Survey-36) [ Time Frame: Week 0, 24 and 48 ]
    : SF-36 comprises 36 items divided into two components of physical health and mental health. Higher scores between 0 and 100 represent better health status

  7. Degree of pain improvement in 100 mm VAS(Visual Analogue Scale) [ Time Frame: Week 0, 24 and 48 ]
    • VAS represents higher scores mean higher pain
    • 0 mm (no pain) and 100 mm (worst pain)
