About this study
Official title: Recovery of Donor Ankle Sensorimotor Function Following Anterior Cruciate Ligament Reconstruction Using Peroneus Longus Tendon Autograft: A Prospective Longitudinal Study
This prospective longitudinal observational cohort study will characterize recovery of donor-ankle sensorimotor function in adults who have undergone primary anterior cruciate ligament reconstruction using a peroneus longus tendon autograft. Twenty participants aged 18 to 55 years will be evaluated at postoperative 6-8 weeks, 3 months, and 6 months. The donor limb and the contralateral non-donor limb will be compared using surface electromyography of the peroneus longus, force-platform measures of postural control, inertial-sensor gait analysis, active ankle joint-position sense testing, and clinical and patient-reported foot and ankle function measures. The study does not assign the surgical procedure or rehabilitation treatment.
Read the detailed description
Peroneus longus tendon autograft is used as an alternative graft source for anterior cruciate ligament reconstruction, but the longitudinal course of donor-site sensorimotor recovery has not been sufficiently described with objective measures. This study is designed to examine within-participant changes over time and differences between the donor and contralateral non-donor limbs.
Eligible participants who underwent primary unilateral anterior cruciate ligament reconstruction with a peroneus longus tendon autograft at Dr. Abdurrahman Yurtaslan Ankara Oncology Training and Research Hospital or Halil Şıvgın Çubuk State Hospital and who are referred to the Sports Health Unit of Gazi University will be followed at postoperative 6-8 weeks, 3 months, and 6 months. No graft type, surgery, or rehabilitation intervention is assigned by the investigators.
At each assessment, peroneus longus activation will be recorded during single-leg heel-rise and medially inclined heel-rise tasks using surface electromyography and normalized to a session-specific maximal voluntary isometric contraction. Postural control will be assessed with KFORCE Plates during double-leg and single-leg balance tasks. Spatiotemporal gait and pelvic kinematics will be recorded with the G-Walk inertial sensor system. Active ankle joint-position sense will be assessed on a Cybex NORM dynamometer using a 15-degree eversion target. Foot and ankle function will be assessed using the Foot and Ankle Ability Measure.
The primary analysis will examine time, limb, and time-by-limb effects across the three postoperative assessments. Parametric data will be analyzed using two-way repeated-measures analysis of variance, with nonparametric alternatives used when assumptions are not met. The planned enrollment is 20 participants, allowing for approximately 20% attrition from the minimum required sample of 16 completers.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Anterior Cruciate Ligament Reconstruction Using a Peroneus Longus Tendon AutograftProcedure or surgery
Participants undergo primary anterior cruciate ligament reconstruction using a peroneus longus tendon autograft as part of their routine clinical care. The graft choice and surgical procedure are determined by the treating orthopedic surgeon independently of study participation. The study does not assign or modify the graft choice, surgical technique, or postoperative rehabilitation. Participants receive routine postoperative rehabilitation according to their clinical needs, while donor-ankle sensorimotor recovery is assessed prospectively at 6-8 weeks, 3 months, and 6 months after surgery.

Each limb will be tested in three trials, and the mean for each condition will be used. Values are expressed in millimeters per second (mm/s); lower values indicate less postural sway. Change from the postoperative 6-8-week assessment to 3 and 6 months and donor-versus-contralateral limb differences will be evaluated.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This prospective longitudinal observational cohort study will characterize recovery of donor-ankle sensorimotor function in adults who have undergone primary anterior cruciate ligament reconstruction using a peroneus longus tendon autograft. Twenty participants aged 18 to 55 years will be evaluated at postoperative 6-8 weeks, 3 months, and 6 months. The donor limb and the contralateral non-donor limb will be compared using surface electromyography of the peroneus longus, force-platform measures of postural control, inertial-sensor gait analysis, active ankle joint-position sense testing, and clinical and patient-reported foot and ankle function measures. The study does not assign the surgical procedure or rehabilitation treatment.
Detailed description
Peroneus longus tendon autograft is used as an alternative graft source for anterior cruciate ligament reconstruction, but the longitudinal course of donor-site sensorimotor recovery has not been sufficiently described with objective measures. This study is designed to examine within-participant changes over time and differences between the donor and contralateral non-donor limbs.
Eligible participants who underwent primary unilateral anterior cruciate ligament reconstruction with a peroneus longus tendon autograft at Dr. Abdurrahman Yurtaslan Ankara Oncology Training and Research Hospital or Halil Şıvgın Çubuk State Hospital and who are referred to the Sports Health Unit of Gazi University will be followed at postoperative 6-8 weeks, 3 months, and 6 months. No graft type, surgery, or rehabilitation intervention is assigned by the investigators.
At each assessment, peroneus longus activation will be recorded during single-leg heel-rise and medially inclined heel-rise tasks using surface electromyography and normalized to a session-specific maximal voluntary isometric contraction. Postural control will be assessed with KFORCE Plates during double-leg and single-leg balance tasks. Spatiotemporal gait and pelvic kinematics will be recorded with the G-Walk inertial sensor system.

Questions about this trial
What is this clinical trial studying?
An observational study of Anterior Cruciate Ligament Injury and Anterior Cruciate Ligament Reconstruction, run by Gazi University at 1 site in Turkey (Türkiye).
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 5 inclusion and 7 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: looking for participants now, as of the sponsor's last update on 9 Oct 2026. 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 Turkey (Türkiye). 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Dudu Ozdemir Can, Msc (+90 5534448492, duduozdemir@gazi.edu.tr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Mean Center of Pressure Velocity During Single-Leg Balance (time frame: Postoperative 6-8 weeks, 3 months, and 6 months). 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 9 Oct 2026.
