PCL Injury Rehab - 7 Week Plan

Generated by MMSx Authority Team

Overview: A Posterior Cruciate Ligament (PCL) injury is a tear or sprain of the ligament at the back of the knee. It often occurs from a direct blow to a bent knee or a hyperextension injury. Unlike ACL injuries, PCL injuries are sometimes managed without surgery, but a structured rehabilitation plan is essential to restore stability and strength. Pain and stiffness are common, and the focus of recovery is to strengthen the quadriceps to compensate for the PCL's function of preventing the tibia from moving too far backward. This 7-week plan follows the NEEBAL framework (Neutral → Elasticity → Endurance → Balance → Activation → Load) to systematically address the issue by managing pain, building foundational strength, and safely re-educating movement patterns. This plan is designed to be a guide, but all movements should be pain-free and approved by a medical professional or physical therapist. A professional's guidance is paramount for this type of recovery.

Pain Profile (10 Parameters)

Technical Name: Posterior Cruciate Ligament Injury
Layman's Description: Stiffness and instability in the back of the knee.
Common Triggers: Trauma (e.g., car dashboard injury), sports falls, or hyperextension.
Movement Pattern Involved: Knee flexion, squatting, and single-leg stability.
Region / Body Part: The back of the knee joint.
Pain Type: A dull ache or a feeling of instability and giving way.
Severity / Stage Tags: Grade 1 (mild sprain), Grade 2 (partial tear), Grade 3 (complete tear).
Suggested Drill Focus: Pain-free range of motion exercises, non-weight-bearing exercises, quadriceps-focused isometrics, and gait re-education.
Red Flags: Severe, unmanageable pain, excessive swelling, fever, or signs of infection.

Warm-Up (5–7 mins)

Light Cardio (2 min): Gentle walking or stationary cycling to increase blood flow to the joint.
Supine Pelvic Tilts (2 min): Lie on your back. Gently rock your pelvis forward and back to gently mobilize the spine and pelvis.
Supine Hip Circles (1 min each leg): Lie on your back. Gently move your hip in a small circle, both clockwise and counterclockwise.
Glute Bridges (10 reps): A gentle activation to wake up the glutes, which are crucial for hip stability.

Weeks 1–2 — Pain & Swelling Management & Gentle Activation (Daily)

Goal: Reduce swelling and pain, restore a pain-free range of motion, and activate the quadriceps. This phase is non-weight-bearing unless cleared by a medical professional.

#	Exercise	Instructions	Key Cues
1	Quad Sets (Isometric)	Sit or lie with your leg straight. Press the back of your knee into the floor and squeeze the thigh muscle. Hold for 5-10 seconds. 10 reps x 3 sets.	Focus on feeling the muscle contract. This is a pain-free way to activate the quads without joint movement.
2	Passive Knee Extension	Lie on your back with a rolled-up towel under your ankle. Allow gravity to gently straighten the knee. Hold for 5-10 minutes, several times per day.	The goal is a pain-free, passive stretch. Do not push through any sharp pain.
3	Straight Leg Raises	Lie on your back. With the knee straight and quad engaged, slowly lift the leg about 6-12 inches off the floor, then lower it with control. 10-15 reps x 3 sets.	This exercise builds quad control. Keep your knee locked out and avoid lifting the leg with your hip flexors.
4	Heel Slides with caution	Lie on your back and slowly slide your heel towards your buttock, bending your knee as far as comfortable. Do not go past 90 degrees of flexion and avoid feeling any pain at the back of the knee. Then slowly slide it back. 10-15 reps x 3 sets.	Keep the movement slow and controlled. Do not force past the point of pain or tightness. Avoid excessive knee flexion.

Cooldown (5–7 mins)

Diaphragmatic Breathing (2 mins): Lie on your back. Focus on slow, deep belly breaths to promote relaxation.
Gentle Hamstring Stretch (1 min each side): Lie on your back and gently pull one knee toward your chest with a towel or band around the foot to gently stretch the hamstring.
Gentle Quad Stretch (1 min each side): Standing, hold onto a chair for balance. Gently pull your ankle towards your buttock.
Self-Assessment (1 min): Briefly assess current discomfort and overall feeling of relaxation. Note any changes.
