From ACL Injury to 100km: Rebuilding Confidence One Step at a Time
When this patient first attended Wimbledon Physiotherapy and Sports Injury Clinic, he presented with a long history of right knee instability following a complete ACL rupture sustained during adolescence while playing football. Over the years he had adapted remarkably well, remaining active despite previous surgical washout procedures and ongoing episodes of pain, swelling, fatigue, and instability.
His main goal was to complete an ambitious 100km endurance walking event.
At assessment, the knee demonstrated signs of chronic overload and reduced confidence in single-leg control, particularly during prolonged walking, downhill terrain, and rotational movements. Functional testing highlighted reduced quad power, hamstring fatigue, mild joint swelling after exertion, and compensatory movement strategies that had developed over time.
During rehabilitation, there were several setbacks. Following periods of increased loading and prolonged walking, symptoms would flare, creating apprehension around exercise progression and concerns about whether the knee could tolerate endurance activity long term. At times the patient described the knee as vulnerable and unstable, especially on uneven ground and during twisting movements.
Treatment focused on carefully graded strengthening, neuromuscular rehabilitation, and endurance preparation. The programme included:
- Quadriceps and hamstring isometric strengthening
- Glut and calf conditioning
- Proprioceptive and balance retraining
- Load management strategies for long-distance walking
- NMES (neuromuscular electrical stimulation) to improve quadriceps activation
- Taping and support strategies to improve confidence and stability
- Recovery guidance including icing, heat, stretching, foam rolling, and pacing advice
As rehabilitation progressed, the patient became increasingly independent with self-management. He transitioned from relying heavily on rigid supports toward more functional taping strategies and gradually rebuilt confidence in the knee. Despite occasional flare-ups, he remained highly motivated and committed throughout the process.
The result was outstanding.
He successfully completed the full 100km walking event a major physical and psychological milestone after years of managing chronic ACL deficiency and knee instability. Following the event, he expressed how grateful he was for the rehabilitation support, education, and guidance that helped him achieve something he previously doubted was possible.
This case highlights that even with longstanding ACL injuries, previous meniscal surgery, and chronic instability, carefully structured rehabilitation, strength development, and confidence-building strategies can allow individuals to return to extremely demanding endurance activities safely and successfully.
