入选标准

  • 1. 1. Has medial compartment joint pain with > 6 months ago a medial partial meniscectomy as confirmed by patient history and MRI
  • 2. Has a KOOS Pain of * 75 (100 being the highest attainable and 0 is no pain)
  • 3. Is between age 30 and 65 years (inclusive) at the time of screening
  • 4. Has neutral alignment ± 5º 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
  • 5. Is willing to be implanted with the Trammpolin® meniscus prosthesis.
  • 6. Is able to do the study required follow up visits, questionnaires, X-rays, CT-scans, and MRI*s
  • 7. Is able and willing to understand and sign the study Informed Consent Form
  • 8. Is able to read and understand the national language of the country in which the relevant clinical site is located

排除标准

  • 1. Has a symptomatic knee because of a tear that could be addressed by a repeat partial
  • meniscectomy
  • 2. Has evidence of a modified Outerbridge Grade IV cartilage loss on the medial tibial plateau or femoral
  • condyle that potentially could contact a Trammpolin® meniscus prosthesis (e.g., a focal lesion > 0.5 cm correlating to a circular defect of > 8 mm in diameter)
  • 3. Has lateral compartment pain and Grade III or Grade IV modified Outerbridge cartilage score in the lateral
  • compartment
  • 4. Has a varus or valgus knee deformity of > 5º requiring a tibial or femoral osteotomy
  • 5. Has a varus alignment that is not passively correctable
  • 6. 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)
  • 7. Has significant trochlear dysplasia, patellar instability or symptomatic patellar misalignment
  • 8. Has patellar compartment pain and Grade III or Grade IV modified Outerbridge cartilage score in the patellar compartment.
  • 9. 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
  • 10. Had an ACL reconstruction performed < 9 months prior to surgery
  • 11. Has a BMI > 32.5 at the time of screening
  • 12. Received any type of prosthetic knee implant made of artificial non-resorbable plastic, metal or ceramic, not including the Trammpolin® meniscus prosthesis
  • 13. Has a knee flexion contracture > 10º
  • 14. Has flexion < 90º
  • 15. Had a previous medial femoral condyle surgery (not including microfracture) or High Tibial Osteotomy (HTO)
  • 16. Has insufficiency fractures or avascular necrosis of the medial compartment
  • 17. Has an active infection or tumor (local or systemic)
  • 18. Has any type of knee joint inflammatory disease including Sjogren*s syndrome
  • 19. Has neuropathic knee osteoarthropathy, also known as Charcot joint
  • 20. Has any medical condition that does not allow possible arthroscopy of the knee
  • 21. Has neurological deficit (sensory, motor, or reflex)
  • 22. Is currently involved in another investigation of the lower extremity
  • 23. Anticipates having another lower extremity surgery during the study period
  • 24. Is contraindicated for corticosteroid injections (i.e., patients with allergy to any of the components or with idiopathic thrombocytopenic purpura)
  • 25. Has received any corticosteroid knee injections * 3 months prior to surgery
  • 26. Has chondrocalcinosis
  • 27. Has proven osteoporosis
  • 28. Is on immunostimulating or immunosuppressing agents
  • 29. Has ipsilateral or contralateral lower limb joint conditions that may affect ambulation or KOOS (e.g. have a leg length discrepancy > 2.5 cm [1 inch], causing a noticeable limp)
