Summary

This study is testing two types of Poly-Tape devices used to rebuild a key ligament in the kneecap. Researchers will follow 59 patients for up to 5 years after surgery to see if the tape helps prevent the kneecap from dislocating again and improves knee function. The goal is to confirm the devices are safe and work well over time.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Poly-Tape devices (10mm Poly-Tape or 5mm Infinity-Lock Tape)
What this could lead to
If successful, this could confirm that Poly-Tape devices are a safe and effective option for repairing the kneecap ligament, helping patients regain stability and function.
What could go wrong
This is a small, non-randomized study with only 59 participants, so results may not apply to everyone. There is a risk of re-dislocation or complications like any surgery.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

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.
