This guide provides general education and does not diagnose a condition or replace individual medical or physiotherapy assessment.
Understanding Recurrent patellar instability
Recurrent patellar instability affects tissue that helps guide and stabilise a joint. Severity ranges from a mild sprain to complete disruption, and associated bone, cartilage or tendon injury can change the rehabilitation pathway.
The diagnosis describes the starting point, not a complete treatment plan. Severity, irritability, medical history, previous injury and the demands of work or sport all influence rehabilitation.
Symptoms and physiotherapy assessment
Assessment aims to confirm the most likely pain or injury pattern, identify current limitations and decide whether physiotherapy is appropriate or medical investigation is needed.
- Mechanism of injury, swelling and bruising
- Joint stability and ability to bear weight or use the limb
- Movement, strength and neurological status
- Need for bracing, imaging or specialist review
Treatment and early management
Early treatment is matched to the examination. It should protect irritable or healing tissue without creating avoidable stiffness, weakness or fear of movement.
- Protect the injured structure without unnecessary complete rest
- Use support or an aid when clinically indicated
- Restore comfortable movement and normal walking or arm use
- Begin safe muscle activation and swelling management
A staged rehabilitation plan
Rehabilitation progresses from settling the current problem to rebuilding the physical qualities the person needs. Exercises are selected and adjusted according to response rather than copied from a one-size-fits-all list.
Later rehabilitation can include quadriceps and hamstring strength, single-leg control, stairs, running, landing, deceleration and planned then reactive change of direction.
- Progress strength through increasingly demanding ranges
- Balance, proprioception and joint-position training
- Landing, hopping, gripping or closed-chain control as relevant
- Reactive and sport- or work-specific drills
Returning to work, exercise or sport
Readiness is based on stability, strength, functional testing, confidence and exposure to the task—not simply the number of weeks since injury.
A useful return plan increases one variable at a time—such as duration, load, speed, range or complexity—then checks the response during the activity and over the following day.
When medical review is important
Prompt review is appropriate when the joint is grossly unstable, cannot be used or loaded, is visibly deformed, repeatedly locks, or follows high-energy trauma.
If the diagnosis is uncertain or progress is not following the expected pattern, the plan should be reviewed and referral arranged where appropriate.
