Brief Summary:

This is a clinical trial, unicentric, prospective, controlled, randomized, double blind during the experimental phase A.

In the experimental phase B, it is contemplated to administer the experimental treatment to the subjects included in the group treated with P-PRP in the event that the first treatment would be significantly more effective, both from a clinical and regenerative point of view

Condition or disease Intervention/treatment Phase
Patellar Tendinopathy Procedure: mesenchymal stem cells Procedure: Pure platelet-rich plasma Not Applicable

Detailed Description:
  • Main objective

    1. Confirm the presence of patellar tendon gap regeneration after the peritendinous and intratendinous infusion of MSV and compare it with the P-PRP group, evaluated by ECO, NMR and UTC.
    2. To evaluate the clinical efficacy of infusion of MSC in refractory patellar tendinopathy compared with the P-PRP group through the subjective clinical evolution of the patient, the EVA and VISA-P questionnaires and the strength of the extensor muscle group measured by dynamometry.
  • Secondary objective 1. To evaluate the feasibility and safety of the advanced therapy medication MSV and P-PRP when applied by percutaneous infusion into the body of the patellar tendinosis, verifying that each of the procedures established in the protocol is feasible and recording the possible adverse effects related with both treatments and adverse events arising during the period of the clinical trial, whether or not related to it

Arm Intervention/treatment
Experimental: mesenchymal stem cells Procedure: mesenchymal stem cells

Autologous bone marrow aspiration is used as a cellular source to obtain MSVs and is subjected to the protocolized anticoagulant procedure. After checking the perfect condition of the shipment and the correct completion of the documentation that accompanies it, the processing of the bone marrow will be carried out.

The processing of the bone marrow will be done in the Cell Therapy Unit of the IBGM under NCF, within 24 hours of the completion of the aspiration

Active Comparator: Pure platelet-rich plasma Procedure: Pure platelet-rich plasma

Under aseptic conditions, in surgical medium, 6 ml of P-PRP will be obtained from 36 ml of autologous peripheral venous blood sample.

The plasma coagulation will be activated by the addition of Cl2Ca at a concentration of 5%.

Primary Outcome Measures :
  1. Improvement in the tendon ecotexture [ Time Frame: 24 months ]
    The patellar tendon will be examined longitudinally and transversely using gray scale and color, exerting a minimum pressure with the probe. Images will be recorded in static and dynamic formats to develop a consensus of the findings.

Secondary Outcome Measures :
  1. Presence of patellar tendon regeneration by the peritendinous and intratendinous infusion of MSV patellar tendinopathy compared to the P-PRP group [ Time Frame: 24 months ]
    Using ECO, RMN and UTC (Ultrasound Tissue Characterisation)

  2. the strength of the extensor muscle group [ Time Frame: 24 months ]
    using dynamometry.

  3. subjective clinical evolution of the patient [ Time Frame: 24 months ]
    Using EVA and VISA-P (Victorian Institute of Sport Assessment (patelar)) questionnaries.

  4. strength of the extensor muscle group [ Time Frame: 24 months ]
    Using dynamometry
