NCT05840887

Brief Summary

This is a prospective randomized double-blind controlled clinical trial with parallel arms and 1:1 allocation. The main objective of the BIOMAT project is to demonstrate, through an RCT, whether the combined approach by knee osteotomy and MAT can provide clinical improvement over knee osteotomy alone for the treatment of patients with monocompartmental knee OA associated with meniscal insufficiency and lower extremity malalignment. Secondary objectives are to demonstrate whether the addition of MAT to knee osteotomy in patients with monocompartmental OA can improve biomechanical parameters and whether this treatment has protective effects on the joint environment and cartilage degeneration.

Outcome Measures

Primary Outcomes (1)

  • IKDC-Subjective Score (Subjective International Knee Documentation Committee)

    This is a subjective, knee-specific rating scale that is considered one of the most reliable assessment tools in the evaluation of knee pathology. The questionnaire examines 3 categories: symptoms, sports activity, and knee function

    12 months follow-up

Secondary Outcomes (11)

  • IKDC-Subjective Score (Subjective International Knee Documentation Committee)

    baseline, 1 month, 3 months and 6months follow-up

  • WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index) score

    baseline, 1 month, 3 months, 6 months and 12 months follow-up

  • KOOS Score ( Knee Injury and Osteoarthritis Outcome score)

    baseline, 1 month, 3 months, 6 and 12 months follow-up

  • VAS-dolore (Visual Analogue Scale)

    baseline, 1 month, 3 months, 6 and 12 months follow-up

  • EQ-VAS

    baseline, 1 month, 3 months, 6 and 12 months follow-up

  • +6 more secondary outcomes

Study Arms (2)

Knee Ostetomy combined with meniscal allograft transplantation

EXPERIMENTAL

The treatment group will perform osteotomy and meniscal allograft transplantation to restore the meniscal deficiency.

Procedure: Knee osteotomy associated with meniscal allograft transplantation

Knee Osteotomy

ACTIVE COMPARATOR

The control group will consist of patients who will perform an isolated osteotomy.

Procedure: Knee osteotomy

Interventions

Knee osteotomy

Knee Osteotomy

Patients will undergo knee osteotomy associated with meniscal allograft transplantation, which will be implanted by arthroscopic technique with body fixation by all-inside and transosseous sutures to the posterior horn and if necessary to the anterior horn.
