Phase 1 Knee Protocol
Phase 1: Knee Stability & VMO Activation
This guide is designed for the first 1–2 weeks of recovery to manage inflammation and restore basic muscle firing patterns.
Clinical Objective
To achieve "Quiet Knee" status: minimal swelling, restored extension, and activation of the Vastus Medialis Obliquus (VMO) to support the patella.

Daily Protocol
Frequency: 2-3 sessions per day
Recommended Gear: Axis-360 Pro Knee Stabilizer (Wear during all standing movements)
1. Quad Sets (The Foundation)
- Action: Sit with your leg straight. Contract your thigh to push the back of your knee into the floor.
- Hold: 5 seconds. Reps: 10.
- Why: This re-establishes the mind-muscle connection without joint irritation.

2. Terminal Knee Extension (TKE)
- Action: Loop a Light Mobility Band behind your knee. Slowly straighten your leg against the resistance.
- Reps: 3 sets of 15.
- Why: Targets the "teardrop" muscle responsible for locking the knee into a stable position.

3. Straight Leg Raises (SLR)
- Action: Lie on your back, lock your knee, and lift your leg 12 inches off the ground.
- Reps: 10 slow controlled lifts.
- Why: Strengthens the hip flexors and quads without the "grinding" pressure on the kneecap.

When to Progress?
You are ready for Phase 2: Functional Loading when:
- You have full knee extension (can get it perfectly flat).
- You can perform 30 seconds of a single-leg stand without pain.
- The "lag" in your straight leg raise has disappeared.
