Comparing surgery and exercise for chronic knee pain

Surgery and Exercise Versus Exercise Only for Chronic Patellofemoral Pain Syndrome: a Randomised Controlled Trial

Not applicable Interventional Canisius-Wilhelmina Hospital · NCT06227806

This study is testing whether combining a specific knee surgery with a home exercise program helps people with chronic knee pain feel better compared to just doing the exercise program alone.

What this trial studies

This clinical trial aims to compare the effectiveness of tibial tubercle transfer surgery combined with a home exercise program against a home exercise program alone in patients suffering from chronic patellofemoral pain syndrome (PFPS). Participants will be randomly assigned to either the surgery group or the exercise-only group. The study will evaluate differences in activity-related pain and patient-reported outcomes between the two groups over time. The goal is to determine whether the surgical intervention provides significant benefits over exercise alone.

Who should consider this trial

Good fit: Ideal candidates are individuals with a history of chronic patellofemoral pain syndrome lasting at least 12 months and specific anatomical criteria.

Not a fit: Patients with previous knee surgeries or other significant knee conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into more effective treatment options for patients with chronic knee pain.

How similar studies have performed: Other studies have explored similar surgical and exercise interventions for knee pain, showing varying degrees of success, but this specific comparison is less commonly tested.
