Anterior Cruciate Ligament Reconstruction Using a Peroneus Longus Tendon Autograft
Anterior Cruciate Ligament Reconstruction Using a Peroneus Longus Tendon Autograft: 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.
Study summary
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.

Inclusion Criteria:
* Age 18 to 55 years.
* Unilateral primary anterior cruciate ligament tear confirmed by clinical examination and magnetic resonance imaging.
* Primary anterior cruciate ligament reconstruction performed using a peroneus longus tendon autograft.
* Able and willing to attend the postoperative assessments at 6-8 weeks, 3 months, and 6 months.
* Written informed consent provided before study participation.
Exclusion Criteria:
* Multiligament knee injury.
* Previous surgery on the index knee or donor ankle.
* Pre-existing ankle instability or major foot or ankle pathology.
* Neurological or neuromuscular disease.
* Inflammatory or systemic disease that may affect the assessments.
* Major lower-extremity deformity that may affect the assessments.
* Unable to complete the postoperative rehabilitation program or scheduled follow-up assessments.
Primary outcome measure(s)
Change in Mean Center of Pressure Velocity During Single-Leg Balance — Postoperative 6-8 weeks, 3 months, and 6 months Mean center of pressure (CoP) velocity during a 10-second single-leg stance, assessed separately with eyes open and eyes closed on KFORCE Plates. 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.
