Trochlear Osteochondral Defect Repair Protocol
Preoperative
Goals:
- Maximize ROM and progress functional strength
- Independent post operative HEP
- Independent in crutch use Non-weight bearing (NWB) including all of patient’s known ambulation barriers (stairs, varied surfaces)
Treatment:
- ROM, joint mobilization
- Aquatics exercise program, Therapeutic exercise program
- Education on HEP to be initiated post operatively
- Crutch training NWB. Include training for any ambulatory barriers
- Any modalities needed for symptomatic control
Phase 1

- SLR 4 directions (no resistance)
- Stationary bike when ROM permits (no resistance)
- Initiate weight shifts by week 2-3
- At week 4
- Multi angle leg press isometric
- Pool program (gait and exercise)
- Modalities for pain and swelling control
- Biofeedback and muscle stim as needed
- gradual return to activities
- NO PROLONGED STANDING
- Strong caution with stair climbing
Phase 2
Postoperative Week 6-12
Goal:

Treatment:
- Brace discontinued by week 6
- Consider unloading brace
- Weight Bearing
- Progress to Weight Bearing As Tolerated
- Full Weight Bearing by week 6-8
- Discontinue crutches Week 6-8
- Gradual increase in ROM
- Maintain full Passive knee extension
- Progress knee flexion to 120-135° by week 8
- Continue patellar mobilizations and soft tissue mobilizations

- Closed kinetic chain exercises (leg press 0-60°) by week 8
- Toe-calf raises by week 6 (full weight)
- Open kinetic chain knee extensions
- No resistance
- Start 0-30 then progress to deeper angles
- Exercise bike (gradually increase time)
- Elliptical week 9-10
- Treadmill walking week 10-12
- Stairmaster at week 12
- Balance a proprioception drills. Progress static to dynamic
- Initiate front and lateral step ups by week 8-10
- Initiate front and lateral step ups and wall squats by week 8-10
- Modalities for pain and swelling control
- Biofeedback and muscle stim as needed
- Continue pool
- Continue slow steady progressions into functional activities
- Increase standing and walking tolerances
