Rebound is a rehabilitation support tool and does not constitute medical advice. It is not a substitute for your physiotherapist or surgeon. Always follow your clinical team's guidance.
Why we built Rebound
In July 2025, I tore my ACL racing motorcycles. I had surgery, and I have been in rehabilitation ever since. Being part of ACL recovery communities, I saw the same story repeated constantly - people weeks or months post-op, doing their best, but without access to a complete and structured rehabilitation protocol and with no clear sense of whether they were doing the right things or progressing safely.
As a former medical doctor with a background in sports medicine and orthopaedic surgery, I knew the clinical frameworks existed. The protocols physiotherapists use in practice are well-established. But most people recovering from ACL surgery never get consistent access to them.
The reality is that specialist sports physiotherapy is expensive. Most people can't afford to be seen frequently enough for it to make a real difference. And even those who can are left on their own between sessions - no guidance, no structure, no way of knowing whether what they're doing day-to-day is right. On top of that, not everyone lives near a clinic with someone who specialises in ACL recovery, and the gap becomes even wider.
The knowledge to recover well exists. The problem is that it has always been locked behind access. So I built Rebound.
ACL recovery is one of the hardest things you will do
Reconstructing your ACL is just the beginning. The rehabilitation that follows typically takes 9 to 12 months or longer - five distinct phases of daily structured exercise, each with different goals, intensity levels, and milestones. It is as much a mental challenge as a physical one. Fear of re-injury, loss of confidence, and frustration with the pace of progress are part of the journey for almost everyone.
Following a structured protocol is not optional - it is what determines whether you achieve a full recovery. Without one, patients risk returning to activity too early, skipping critical strengthening phases, or losing motivation during the long middle months.
Most patients receive a programme from their surgeon or physiotherapist, but between appointments - which can be weeks apart - there is no guidance on what to do today, whether your pain levels are normal, or whether it is safe to progress.

Professional-level recovery, on your phone
Professional athletes recover because they have dedicated rehab teams managing every detail of their recovery, every day. Most people do not have that - whether you are a competitive amateur, a weekend runner, or someone who just wants to walk without pain again.
Rebound puts that same level of structured, daily guidance on your phone. Personalised to your graft type, your injury, and your timeline. It tells you exactly what to do every day, advances you through five phases based on real criteria - not arbitrary timelines - and monitors your safety throughout.
Personalised to your surgery
Your graft type, injury profile, and additional procedures determine your protocol.
Guided daily sessions
One exercise at a time with sets, reps, load targets, coaching cues, and rest timers.
Criterion-based progression
Gate assessments with step-by-step instructions, so you advance when your body is ready.
Recovery beyond exercise
Phase-specific guidance on stretching, nutrition, sleep, and when to ice. A confidence journal to track your mental recovery alongside the physical.
Track everything
Full programme timeline, session logs, assessment history, pain reports, and streaks. See your entire recovery journey at a glance.
Pain and safety monitoring
Log pain during any session. The app responds in real-time - continue, reduce load, stop and rest, or end session. Red flag alerts keep you safe.
Smart missed session handling
Life gets in the way. The app adjusts based on how long you have been away and what you missed. No punishment - just intelligent re-entry.
