About this study

Official title: Treatment of Patella Dislocation in Childhood and Adolescence. Soft Tissue Realignment of the Tibial Insertion of the Patella Tendon. Long-term Outcome.

Soft tissue realignment of the tibial insertion of the patella tendon is a simple operative technique for treating dislocation of the patella in childhood and adolescence. It is performed in children with either recurrent dislocation or complicated primary dislocation in cases with malalignment or maltracking of the patella and a lateralised tibial tuberosity. It can be performed in patients with open epiphyses. We investigate long-term outcome after this procedure.

Read the detailed description

Method. Investigation of the outcome of a relatively new method for centralisation of the insertion of the patella tendon in patients with open epiphyses. Using a soft tissue technique the patella tendon is released from the tibial tuberosity with the tendon still fixed to the distal periosteum. The tibial periosteum is split on the lateral border of the tibia distally. Together with lateral release this procedure releases the patella tendon which finds a new insertion more medially. Because the tendon is still fixed at the distal periosteum no additional fixation is needed and therefore no complications occur at the tibial apophysis due to osteosynthetic material. Full weight bearing is possible after 4 weeks and movement is not restricted.Results. From 1999 to 2004 a total of about 90 operations in about 80 patients for soft tissue centralisation of the distal insertion of the patella tendon were carried out on children and adolescents aged between 10 and 18 years old. This study is a retrospective analysis of the outcome after 6 to 10 years. Relevant outcome criteria will be evaluated with the occurrence of recurring dislocation, the Lysholm score, the Tegner activity scale and subjective measurement with the VAS scale and an additional functional outcome score, that we created especially for children. Eventual occurrence of growth disturbance or osteoarthritis will be documented be clinical or radiological features.

Questions about this trial

What is this clinical trial studying?

A study testing Medialising insertion of patella tendon in people with Patella Dislocation, run by Medical University of Graz.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Feb 2012. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Lyshom Score, Tegner-activity scale, VAS Pain assessment.Own examination form especially for children (time frame: 6 to 10 Years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Feb 2012.
