  Purpose

This is a 1:1 randomised pilot study in 30 patients in 1 site in Helsinki, Finland.

The investigators hypothesize that function, pain, type and quality of cartilage in adult patients with osteochondritis dissecans of the knee will be better in the DBX group compared to the mosaicplasty group.


Condition Intervention Phase
Osteochondritis Dissecans
Device: DBX Putty
Procedure: Mosaicplasty
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Single Blind (Subject)
Primary Purpose: Treatment
Official Title: A Randomized, Subject-blind, Controlled Pilot Trial to Evaluate the Effectiveness and Safety of the Use of Demineralized Bone Matrix (DBX®) Versus Mosaicplasty in the Treatment of Late-Stage Osteochondritis Dissecans (OCD) of the Knee in Patients With a Mature Skeleton

Further study details as provided by Synthes GmbH:

Primary Outcome Measures:
  • Change of Brittberg-Peterson functional assessment score from baseline until 12 months post-op [ Time Frame: At enrollment (day -7), at full weight-bearing (6-8 weeks post-operative), 6 months post-operative, 12 months post-operative ] [ Designated as safety issue: No ]
    Score 0-130 (see Clin Orthop Relat Res 2000 May;374:212-34) to assess function and pain


Secondary Outcome Measures:
  • Type and quality of the formed cartilage to assess the effectiveness of the treatment [ Time Frame: 12 months post-operative ] [ Designated as safety issue: No ]
    The type and quality of the newly formed cartilage will be assessed with arthroscopy and/or MRI /dGEMRIC)

  • Number of patients with complications to assess the safety of the use of the treatment [ Time Frame: Enrolment (day -7) until 12 months post-operative ] [ Designated as safety issue: Yes ]
    All adverse events and complications will be recorded throughout the trial and assessed for severity and causality.

  • History of alcohol abuse or illegal drug use.
  • Participation in any other device or drug trial within 3 months prior to the inclusion in the study
  • Presence of at least one contraindication for DBX® Putty
