BACKGROUND: This study sought to evaluate the thickness of supportive bands and ligaments surrounding the patella in post-stroke patients, with the objective of informing tailored rehabilitation interventions. This is necessitated by the ambiguous effects of tissue alterations on pain and joint injury.
METHODS: We assessed first-time stroke patients aged 30-80 years within one year post-onset using ultrasound. The thickness of the patellar tendon, quadriceps tendon, and medial and lateral patellofemoral ligaments was measured on both affected and unaffected sides. We also evaluated the differences in thickness (horizontal and vertical power) across patients with varying disease durations.
RESULTS: Significant differences in horizontal power were found between sides, diminishing on the unaffected side with longer disease duration. Vertical power varied on the affected side depending on whether the disease duration was above or below 60 days. The mean power center shifted medially and laterally on the affected and unaffected sides, respectively, within the first 60 days, and further shifted downwards and laterally in patients beyond 60 days.
CONCLUSIONS: Support tissue distribution around the patella differs between sides in hemiplegic patients, with changes becoming more pronounced over time. Rehabilitation should include targeted muscle training to prevent knee injuries and enhance recovery.
