NCT02760589

Brief Summary

The purpose of the study is a clinical evaluation with special regard to magnetic resonance imaging and functional performance at least one year after injury / surgery in all three groups (subjects who underwent InternalBrace surgery, subjects who underwent surgery with a semitendinosus graft and subjects who were treated conservatively).

Outcome Measures

Primary Outcomes (1)

  • Signal Intensity in Magnetic resonance Imaging

    The integration of the ligament in magnetic resonance imaging is represented by using values from 1 to 3 (1= continuous ligament; 2= wavy but continuous ligament contour; 3= non-delineated ligament) which are determined by an experienced independent radiologist. Source of the data: axial, coronal, and sagittal scans with proton density-weighted sequences with and without fat saturation by a 1.5-Tesla MRI unit (1.5-Tesla MRI unit, Espree; Siemens AG, Erlangen, Germany).

    at least one year after injury

Secondary Outcomes (7)

  • Limb symmetry Index

    at least one year after Injury / surgery

  • Subjective Outcome: German Version of the IKDC Subjective Knee Form (International Knee Documentation Committee

    at least one year after Injury

  • Subjective Outcome: German Version of the WOMAC (Western Ontario and McMaster Universities Arthritis Index

    at least one year after Injury

  • Subjective Outcome: SF-12 (short form)

    at least one year after Injury

  • Subjective Outcome: German Version of the KOOS (Knee Osteoarthritis Outcome Score)

    at least one year after Injury

  • +2 more secondary outcomes

Sampling MethodNon-Probability Sample
Study Population

Patients with rupture of the ACL between 18 and 60 years

You may qualify if:

  • Female and male subjects
  • Age between 18 and 60 years
  • Patients who sustained an isolated rupture of the anterior cruciate ligament at least 12 month after injury (for the subjects who received conservative therapy), respectively surgery (for the two groups in which subjects underwent surgery)
  • MRI-confirmed tear of the anterior cruciate ligament near the femoral attachment
  • Surgical treatment of the InternalBrace group must have been performed within the first six weeks after injury
  • Women of reproductive age
  • Confirmed written consent of each subject

You may not qualify if:

  • Injury to the other knee
  • Previous knee injuries which required treatment
  • Concomitant injuries such as fractures, articular cartilage lesions reaching subchondral bone, meniscal tears or lesions of the collateral ligaments which required an additional surgical intervention and therefore an extended post-op rehabilitation protocol
  • Pregnant and nursing women
  • Claustrophobia
  • Existing contraindication against performing an MRI scan
  • Taking certain concomitant medication(s) (especially cortisone), or conditions that interfere with a patient's ability to comply with all procedures
  • Circumstances that interfere with the participant's ability to give informed consent (diminished understanding or comprehension, or a language other than German or English spoken
