Before You Start

Who is this guide for?

After patellar dislocation and assessment of associated injuries. After surgery, select only entries compatible with the surgeon’s protocol: this catalogue does not define postoperative weight bearing, brace use or movement limits.

What you need

A stable, clear surface, comfortable clothing and a secure support. Check resistance-band anchors. Adult supervision; avoid marbles and small objects if the child may put them in their mouth, using a towel instead.

Suggested frequency

Perform only the exercises selected during the visit. The listed dosages are examples to adapt: follow the dose, frequency, rest and progression prescribed for age, symptoms and phase. Do not automatically perform the whole list.

Common mistakes to avoid

  • •Forcing a painful or unauthorised movement
  • •Increasing load, resistance or frequency without the agreed rest periods
  • •Doing balance exercises without stable support or supervision

⚠️ Red flags — when to stop and contact the doctor immediately

Stop exercises immediately and contact the specialist if any of the following occur:

  • Acute or sudden pain during exercise
  • Significant swelling after exercises
  • Pain that progressively worsens over days
  • Fever or general malaise
  • Difficulty walking or using the limb after exercises
  • Any neurological symptoms (tingling, numbness, sudden weakness)
  • A red or hot joint, or inability to bear weight: seek prompt assessment; use emergency care if severe.
In case of doubt, always prefer a check-up over continuing exercises.

Detailed Exercises

    Quadriceps activation

    Global quadriceps recovery is the basis of patellar control

    Illustration: Quadriceps activation

    Seated with leg extended, small rolled towel under knee. Press knee down (squashing towel) while slightly lifting heel off floor. Hold 5-10 seconds. Aim for a full, even contraction of the whole quadriceps, without trying to isolate a single portion of the muscle. In the early phases it is one of the most used exercises, because it reactivates the quadriceps safely; progression is based on pain control and contraction quality, not on repetition count.

    3 × 15-20 repetitions, several times daily

    Straight leg raise (SLR)

    Quadriceps strengthening without bending knee

    Illustration: Straight leg raise (SLR)

    Only when permitted in your pathway. Lying on your back, contract the quadriceps with the knee straight, then slowly raise the leg to the taught height. If the knee bends during the lift (extension lag), stop and have quadriceps activation, assistance or bracing reassessed by the physiotherapist; do not compensate by increasing effort. After surgery follow the specific restrictions.

    3 × 15-20 reps, 2-3 times daily

    Controlled mini-squat (0-30°)

    Shallow squat at the authorised stage and range; patellofemoral loading varies with angle, technique and resistance.

    Illustration: Controlled mini-squat (0-30°)

    Standing with back to wall or holding support. Descend ONLY 20-30° knee flexion (very shallow squat). Patella is under more stress at greater flexion degrees, so limiting movement is protective. Rise slowly. Feet shoulder-width, weight evenly distributed.

    3 × 10-15 reps, slow movement
  • 4

    Lateral step-up

    Strengthens lateral patellar control

    Illustration: Lateral step-up

    Standing sideways to low step (10-15 cm). Step up with affected leg, then lower controlling movement. Observe that knee doesn't "collapse" inward during rise. If it does, lower step. Progress to higher step only when control is excellent.

    3 × 10 per leg, progressive height
  • 5

    Gluteus medius and maximus strengthening

    Hip strengthening for strength and control; patellar instability is multifactorial and is not simply caused by “weak glutes”.

    Illustration: Gluteus medius and maximus strengthening

    Use the selected versions: a side-lying clamshell without rolling the pelvis, a supine bridge or side-lying hip abduction. Agree range and resistance at the authorised stage. Hip work supports limb strength and control; patellar instability also depends on anatomy and associated injuries, not only gluteal strength.

    3 × 15 for each exercise
  • 6

    Proprioception and balance

    Recover knee position sense

    Illustration: Proprioception and balance

    After clearance for weight bearing, start on firm ground with eyes open, next to a secure support and with adult supervision. Place the other foot down before losing balance. Progress to an unstable surface or eyes-closed work only under direct professional supervision; do not add these challenges independently. Stop for pain or instability.

    3 × 30 seconds per level

    Motor control with visual feedback

    Learn to control knee during movements

    Illustration: Motor control with visual feedback

    In front of mirror, perform squats, step-ups and lunges checking that the knee stays aligned over the 2nd toe throughout the movement. Knee must NOT "collapse" inward. If it does, actively correct or reduce range of motion. This motor-control retraining is one of the elements associated with a lower risk of recurrence and is a useful criterion before return to sport.

    Integrate control into ALL exercises

    Quadriceps and lateral chain stretch

    Soft-tissue mobility when indicated; the IT band or retinaculum are not assumed to “push” the patella laterally by themselves.

    Illustration: Quadriceps and lateral chain stretch

    QUADRICEPS: standing with support, pull the heel toward the buttock keeping knees together and pelvis tucked, 30 seconds. LATERAL CHAIN: standing, cross the affected leg behind the other and lean the trunk to the opposite side, feeling the stretch along the side and outer thigh. You can add foam-roller self-massage on the outer thigh, avoiding the painful area of the kneecap.

    3 × 30 seconds per exercise, daily

    Controlled landing and progressive plyometrics

    Plyometrics and landing work in the advanced phase after recovery of strength and control; there is no universal starting week.

    Illustration: Controlled landing and progressive plyometrics

    Only from the advanced phase (usually after 10-12 weeks) and with specialist clearance. Start by stepping down from a low step and landing on two feet with soft knees, aligned over the feet and silent. Progress to: hops in place, forward-backward jumps, lateral jumps, single-leg landing. If the knee collapses inward or a feeling of instability appears, go back to the previous stage.

    3 × 8-10 reps per level, 2-3 times a week

    Gradual return to sport

    Protected progression toward sports activities

    Illustration: Gradual return to sport

    Return to sport follows the pathway for the dislocation, associated injuries and any surgery. First regain movement, strength, control and confidence in the knee; then introduce straight running, direction changes, jumps and sport-specific tasks as authorised. Do not progress simply because a set week has arrived. Full-training tolerance, no subsequent worsening and clinical assessment are required. Any brace is an individual choice and does not replace rehabilitation.

Frequently Asked Questions

How long does recovery take after a patellar dislocation?

Recovery often takes several months; 3-6 months is an approximate reference, not a promise or a rule for every operation. Bracing, protection and mobilisation depend on stability, associated injuries and treatment. Return to sport requires clinical and functional assessment, rather than the passage of weeks alone.

Can it happen again?

Unfortunately yes, recurrence risk after first dislocation is significant (15-40%). Global quadriceps recovery, hip strength and neuromuscular control are essential to reduce this risk. In some cases surgery may be indicated.

When can I return to sports?

The decision considers pain and effusion, motion, strength, single-leg control, the quality of jumping and changes of direction when appropriate, and confidence in the knee. Comparison with the other leg is useful but can mask weakness in both legs: an isolated percentage, such as 85%, is not enough. The team interprets tests according to age, treatment and sport and plans a gradual return; associated injuries or surgery change the pathway.
