Study summary

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.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Males or females, age between 18 years and 65 years
  • Females of must have a negative serum or urine pregnancy test at the time of inclusion
  • Females of childbearing potential must be willing to use effective means of for at least 1 year post surgery. Medically acceptable contraceptives include:

    1. Surgical sterilisation
    2. Approved hormonal contraceptives
    3. Barriers methods combined with a spermicide
    4. An intrauterine device
    5. Abstinence alone is not considered an acceptable method of contraception
  • Late stage Osteochondritis Dissecans (ICD-10 code M93.2) of the knee classified as stage III or IV (Anderson MRI classification)
  • Mature skeleton
  • Written prior to any study specific procedures (except the procedures necessary to determine eligibility)
  • Ability and willingness to comply with all study specific procedures, including attending all follow-up visits up to 12 months postoperative and completing questionnaires in a local language

Exclusion criteria

Exclusion Criteria:

  • More than 1 knee affected
  • Patients who can be treated with conservative treatment alone, unless there is evidence of at least 6 months failed previous treatment
  • Systemic disease including AIDS, , Hepatitis or any other disease that would prevent normal organ and marrow function.
  • Patients undergoing systemic cortisone treatment or therapy (e.g. avascular necrosis)
  • Patients undergoing active cancer therapy (chemotherapy, radiation treatment).
  • 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 for DBX® Putty
Terms in these criteria, in plain language(6)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

What researchers measure

Primary outcomes

  1. Change of Brittberg-Peterson functional assessment score from baseline until 12 months post-op

    Score 0-130 (see Clin Orthop Relat Res 2000 May;374:212-34) to assess function and pain

    Time frame: At enrollment (day -7), at full weight-bearing (6-8 weeks post-operative), 6 months post-operative, 12 months post-operative

Secondary outcomes

  1. Type and quality of the formed cartilage to assess the effectiveness of the treatment

    The type and quality of the newly formed cartilage will be assessed with arthroscopy and/or MRI /dGEMRIC)

    Time frame: 12 months post-operative

  2. Number of patients with complications to assess the safety of the use of the treatment

    All adverse events and complications will be recorded throughout the trial and assessed for severity and causality.

    Time frame: Enrolment (day -7) until 12 months post-operative
