Overview

This is a Post Market Clinical Follow Up Study in Orthopaedics. It will verify the long-term safety and performance of the device in the intended patient population, when indicated for the reconstruction of a ligament in the kneecap - the Medial Patellofemoral ligament (MPFL).

The Medical Device in this study, Poly-Tape, is a Class IIb CE-Marked device manufactured by Xiros Ltd. Poly-tapes are a single-use device, they are indicated for patients repair of soft tissue and/or reconstruction of ligaments, tendons, and other soft tissues. The device can be fixed to the bone using several different methods including screws.

This study is a prospective, multicentre, consecutively recruited non-randomised study. The total length of the study is expected to be 7 years. This includes a recruitment period of approximately 24 months and a 5-year follow-up. A total of 55 subjects will be enrolled into the study with follow up at 6 months, 1 year, 2 years and 5 years in clinic and by questionnaires. All subjects treated with the Poly-Tape for MPFL reconstruction, will be consecutively recruited into the study.

Eligibility

Inclusion Criteria:

        Patient must be 13 years old or above. Patients who require MPFL reconstruction. Patients
        willing to participate in the study and have been informed of the nature of the study,
        agree to its follow-up and have provided written informed consent as approved by the
        Research Ethics Committee (REC).
        Exclusion Criteria:
        These devices should not be used in procedures which bridge, disturb, or disrupt the growth
        plate in immature patients since they will not elongate as the patient grows.
        Patients known to be hypersensitive to titanium alloy or polyester. Appropriate tests
        should be carried out on patients with suspected material sensitivity prior to
        implantation.
        Patients with any infections or structural or pathological condition of the bone or soft
        tissue that would be expected to impair healing or secure fixation. Bone quality should be
        assessed prior to surgery.
        Patients who are unable or unwilling to restrict activities to prescribed levels or to
        follow the rehabilitation instructions during the healing period.
        Patients for whom the implantation is intended to be non-permanent, since they integrate
        well with the patient's tissue.
