Outcome Measures

Primary Outcomes (1)

  • Performance of the Trammpolin® medial meniscus prosthesis

    Performance of the Trammpolin® medial meniscus prosthesis in improving pain as assessed by the Knee Osteoarthritis and injury Outcome Score (KOOS) Pain Sub-scale at 24 months post-operative compared to baseline (pre-operative) The minimum value is 0 and maximum value is 100, a score of 100 is being no pain and the highest attainable score

    24 months

Secondary Outcomes (13)

  • Knee Osteoarthritis and injury Outcome Score (KOOS) Pain

    6 weeks, 3 months, 6 months, 12 months and 24 months

  • Knee Osteoarthritis and injury Outcome Score (KOOS) overall

    at 6 weeks, 3 months, 6 months, 12 months and 24 months post-operative compared to baseline (pre-operative).

  • PAIN Visual Analog Scale (VAS)

    at 6 weeks, 3 months, 6 months, 12 months and 24 months post-operative

  • Lysholm Knee Scoring Scale

    at 6 weeks, 3 months, 6 months, 12 months and 24 months

  • Oxford Knee Score

    at 6, 12 and 24 months

  • +8 more secondary outcomes

Study Arms (1)

Single arm

OTHER

Implantation of a medial meniscus prosthesis in the medial knee compartment of a post medial meniscectomy knee.

Device: Trammpolin medial meniscus prosthesis

Interventions

Implantation of the Trammpolin medial meniscus prosthesis in patients with a severe medial meniscus damage

Single arm

Eligibility Criteria

Age18 Years - 70 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Has medial compartment knee pain and had a medial partial or total meniscectomy \> 6 months ago. The lack of meniscus tissue is confirmed by patient history and MRI
  • Has a KOOS Pain of ≤ 75 (100 being no pain and the highest attainable score)
  • Is between age 18 and 70 years (inclusive) at the time of screening
  • Has neutral alignment ± 5° of the mechanical axis, i.e., the angle formed by a line drawn from the center of the femoral head to the medial tibial spine and a line drawn from the medial tibial spine to the center of the ankle joint, as confirmed by X-ray
  • Is willing to be implanted with the Trammpolin® medial meniscus prosthesis
  • Is willing and able to comply to the clinical investigation required follow up visits, questionnaires, X-rays and MRI's
  • Is able and willing to understand and sign the clinical investigation Informed Consent Form
  • Is able to read and understand the national language of the country in which the relevant clinical site is located

You may not qualify if:

  • Has a symptomatic knee because of a tear that could potentially be addressed by a repeat partial meniscectomy
  • Has evidence of a modified Outerbridge Grade IV cartilage loss on the medial tibial plateau or femoral condyle that potentially could contact a Trammpolin® medial meniscus prosthesis
  • Has lateral compartment pain and Grade III or Grade IV modified Outerbridge cartilage score in the lateral compartment
  • Has a varus or valgus knee deformity of \> 5° requiring a tibial or femoral osteotomy
  • Has a varus alignment that is not passively correctable
  • Has a laxity level of more than Grade II (IKDC), primary or secondary to an injury of the anterior cruciate ligament (ACL) and/or posterior cruciate ligament (PCL) and/or lateral collateral ligament (LCL) and/or medial collateral ligament (MCL)
  • Has significant trochlear dysplasia, patellar instability or symptomatic patellar misalignment
  • Has patellar compartment pain and Grade III or Grade IV modified Outerbridge cartilage score in the patellar compartment.
  • Compared to a normal knee, has obvious radiological evidence of medial femoral squaring, anatomical variance in the medial tibial plateau, or irregularly shaped cartilage surface
  • Had an ACL reconstruction performed \< 9 months prior to surgery
  • Has a BMI \> 30 at the time of screening
  • Has a knee flexion contracture \> 10°
  • Has a knee flexion \< 90°
  • Had a previous High Tibial Osteotomy (HTO) \< 1 year ago
  • Has insufficiency fractures or avascular necrosis of the medial compartment
  • +14 more criteria
