NCT04943341

Brief Summary

The aim of this pilot study is to evaluate the clinical and radiological outcomes (ultrasound and MRI) for a treatment utilized in the medial plica syndrome resistant to conservative therapy. Will be evaluated an intra-plica ultrasound-guided injections of Triamcinolone-Acetonide and lidocaine percutaneously, and associated rehabilitation therapy. The aim of the study will be to evaluate the efficacy and safety of the injection procedure by revealing clinical improvement and monitoring the incidence of adverse events following treatment.

Outcome Measures

Primary Outcomes (1)

  • KUJALA Scale (Kujala Anterior Knee Pain Scale (AKPS

    This is a patient-reported assessment of patellofemoral disorders that evaluates subjective symptoms and functional limitations. The evaluation consist of 13 questions with a total score of 100 points.

Study Arms (1)

Eco-guided Triamcinolone-Acetonide injection

EXPERIMENTAL

Patients affected by medial plica syndrome will be treated with an eco-guided injection of Triamcinolone-Acetonide.

Procedure: Eco-guided Triamcinolone-Acetonide injection

Interventions

The treatment consists in injecting 1 ml of Kenacort (corresponding to 40 mg of Triamcinolone Acetonide) diluted in about 1 ml of local anesthetic (Lidocaine) directly into the medial fold of the knee. Through an ultrasound guidance with "in plane" technique, the flute beak of the needle will be positioned between the two sheets of the synovial fold and the injection will be performed.

Eco-guided Triamcinolone-Acetonide injection

Eligibility Criteria

Age18 Years - 50 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Ultrasonographic and/or MRI signs of medial plica pathology;
  • Failure, defined as the persistence of symptomatology, after at least one course of conservative treatment of at least 6 weeks (rest and drug treatment, physiotherapy);
  • Ability and consent of patients to actively participate in clinical follow-up;

You may not qualify if:

  • BMI \> 35;
  • Patients with: rheumatic diseases, diabetes, infectious processes, epilepsy, severe stage osteoporosis
  • Patients undergoing intra-tendon infiltration of other substance within the previous 6 months;
  • Patients undergoing surgery on the affected knee within the previous 12 months;
  • Patients undergoing femoro- patellar joint stabilization surgery to the affected knee;
  • Trauma to the affected knee within the past 6 months;
  • Episodes of patellar dislocation and subluxation to the affected knee;
  • State of immunodepression;
  • Ongoing systemic inflammatory diseases (stabilized outcomes of these diseases are not considered absolute contraindications).
  • Contraindications to use or hypersensitivity to the active ingredient (Triamcinolone Acetonide) or to the excipients (sodium chloride, benzyl alcohol, sodium carboxymethylcellulose, polysorbate 80 and water for injectable preparations)found within Kenacort as per the product package insert;
  • \. Contraindications or hypersensitivity to the active ingredient of the local anesthetic (Lidocaine) or their excipients; 13. Pregnancy or lactation status or intention to become pregnant during the period of study participation. In particular, in the case of a suspected pregnancy , this will be excluded by serological testing (hCG).
