Trial summary

At the foot and ankle group at the Department of Orthopaedics, Uppsala University Hospital, the routine is to perform a tendon transfer of peroneus longus to brevis in case of a ruptured peroneus brevis tendon in the ankle. The reports of patient outcome from this surgery varies in different studies. Read more about this study

About this study

At the foot and ankle group at the Department of Orthopaedics, Uppsala University Hospital, the routine is to perform a tendon transfer of peroneus longus to brevis in case of a ruptured peroneus brevis tendon in the ankle. The reports of patient outcome from this surgery varies in different studies. The aim of the current study is to analyse how well the patients think their general health has improved after the surgery, and how they perceive that the foot function has changed after the surgery. In an objective way the changes in gait after surgery will be measured with gait analysis.

Read the detailed description

The patients are asked to fill in Short Form 36 (SF 36) and Foot and Ankle Outcome Score (FAOS) before surgery, six months and one year after surgery. At each visit a clinical examination is done by a foot and ankle surgeon, according to a protocol. At the same visit a gait analysis is performed with force plates, registration of speed and gait length and 3D recording. The surgery itself is performed according to the clinic's usual protocol and standardised, so all patients are treated in the same way. The physiotherapy is also done according to a protocol. The surgeon is not involved in the follow- up, this is done by another surgeon, and the gait analysis is done by a physiotherapist.

The patients are chosen from two groups: primary tear of the peroneus brevis tendon, requiring a longus to brevis transfer, and primary tear of the peroneus longus tendon, requiring removal of the tendon.

The first group has a sub-group: patients who are in need of a calcaneal osteotomy because of a severe varus hindfoot. The reason the study group is so heterogenous is that peroneus longus and brevis tears are very rare, and 10 patients are referred to the Orthoaedic deparment each year, that need this type of surgery. The sample size has been calculated to 30 patients (based on changes in force measurements during gate), but more patients need to be involved in the study in order to have 30 patients at one year follow up.

Study groupRoleWhat they receive
Patients with tears to their peroneal tendonsPatients with pain over their peroneal tendons clinically, with a verified injury to either of the two tendons on MRI, where we might expect a tendon transfer of the peroneus longus, or extirpation of the peroneus longus, during surgery.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Changes in quality of life one year after foot surgery including a peroneus longus transfer

    Patients quality of life is measured with the self-administered Short Form 36 ( SF 36 ) (range 0-100 points, 100 points best health) before surgery, at 6 months and 12 months after surgery.

    Measured: Before surgery to 12 months after surgery

  2. Changes in foot function one year after surgery including a peroneus longus transfer

    Changes in foot function after surgery is measured using a patient reported outcome measure: Foot and Ankle Outcome Score (FAOS) (range 0-100 points, 100 points being a totally healthy foot). The patient fill in the score before surgery, at 6 months and 12 months after surgery.

    Measured: Before surgery to 12 months after surgery

Secondary outcomes (1)
  1. Weakness in push-off during gait

    After removal of the peroneus longus tendon one might observe a weakness in the plantar flexion of the first metatarsal bone, leading to a weakness in push off during gait. This will be measured on the RSscan pressure mat (from RSscan International), recording the pressure at push-off in Newtons/ m2. The patient will be walking both bare foot and with shoes. Measurements are done before surgery, at 6 months and 12 months after surgery.

    Measured: One year after surgery

Questions about this trial

What is this clinical trial studying?

An observational study of Patient Satisfaction and Gait, Rigid, run by Anna Sprinchorn at 1 site in Sweden.

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 2 inclusion and 4 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: status not confirmed, as of the sponsor's last update on 30 Nov 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Sweden. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

Results are not available in the source record.

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?

Changes in quality of life one year after foot surgery including a peroneus longus transfer (time frame: Before surgery to 12 months after surgery). The study lists 2 primary outcomes in all. 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 30 Nov 2023.
