Rebuilding a knee after severe trauma requires a precise biomechanical blueprint—especially for a sedentary, 60-year-old female with a thin frame and no prior exercise history. This complex case involved complete tears of both the Medial Collateral Ligament (MCL) and the Medial Patellofemoral Ligament (MPFL), requiring 1.5 months of strict immobilization in a 20-degree flexion brace to allow these primary medial stabilizers to heal.
To safely restore stability and combat arthrogenic muscle inhibition, a phased, 3-month rehabilitation strategy was implemented:
Phase 1: Mat-Based Activation
Initial care utilized gravity-eliminated mat exercises alongside daily heel drags. Focus centered on waking up the gluteus maximus and medius to prevent valgus collapse (which would stress the healing MCL), while using Straight Leg Raises (SLRs) and Terminal Knee Extension (TKE) to safely re-engage the quadriceps and support patellar tracking without overloading the healing MPFL.
Phase 2: Progressive Closed-Chain Loading
Post-brace removal, stationary cycling promoted non-weight-bearing joint lubrication. We transitioned to standing via pillar-assisted squats, reducing axial load while safely restoring flexion range. Progressive resistance within available, stable ranges followed to build muscular tissue tolerance.
Phase 3: Terminal Range & Deceleration
The final weeks captured the stubborn, end-range 10 degrees of knee flexion. Eccentric training was integrated to build essential deceleration capacity, paired with dynamic mobility work to solidify long-term joint autonomy.
The Outcome
The 3-month timeline utilized a step-down frequency (3 sessions/week for two months, tapering to 2/week). The patient was successfully discharged with full mobility, strength, and functional independence—proving that structured, phased programming can safely guide an unconditioned patient through complex ligamentous recovery.
