Achilles Tendon Repair

RESTRICTIONS: 

  • NO weight bearing on operative extremity x4 weeks 
  • NO dorsiflexion past neutral x8 weeks 

Phase I: Protection (Weeks 0–2)

Goals
 

  • Protect the repair 
  • Control pain and swelling with consistent elevation 
  • Maintain proximal lower extremity strength 

Immobilization 

  • Posterior splint in approximately 20° plantarflexion 

Weight Bearing 

  • Non-weight bearing with crutches or knee scooter 

Range of Motion 

  • Active ROM of knee and hip encouraged 

Therapeutic Exercises 

  • Quad sets 
  • Straight leg raises 
  • Core exercises 

Precautions 

  • Keep splint clean and dry 

Criteria to Progress 

  • Incision healed 
  • Pain controlled 
  • Minimal swelling 

Phase II: Early Motion (Weeks 2–6) 

Goals 

  • Protect repair while initiating tendon mobility 
  • Gradually return to light weight bearing 
  • Reduce edema 
  • Prevent stiffness 

Immobilization 

  • CAM walking boot with 3 heel wedges (approximately 1 inch lift) 

Weight Bearing 

  • Week 4: Partial weight bearing (progress 25% à 50%) in boot with heel wedges 
  • Full weight bearing in boot around 6 to 8 weeks 

Range of Motion 

Begin gentle active ROM 

  • Plantarflexion 
  • Inversion/Eversion 
  • Dorsiflexion only to neutral (0°) 

Avoid dorsiflexion beyond neutral until at least 8 weeks. 

Therapeutic Exercises 

  • Ankle AROM 
  • Gentle seated heel raises (minimal load) 
  • Intrinsic foot strengthening 
  • Stationary bike (boot on, minimal resistance) 
  • Core and proximal hip strengthening 

Precautions 

  • No resisted plantarflexion 
  • No passive dorsiflexion stretching 
  • Avoid barefoot walking 

Criteria to Progress 

  • Full weight bearing in boot 
  • Minimal swelling 
  • ROM to neutral without pain 

Phase III: Motion & Early Strengthening (Weeks 6–12) 

Goals 

  • Restore normal gait 
  • Improve ROM 
  • Improve proprioception 

Weight Bearing 

  • Remove one wedge every week beginning at week 6 until all removed at 8 weeks 
  • Transition from CAM boot to supportive athletic shoe with heel lift 
  • Gradually discontinue heel lift over several weeks 

Range of Motion 

  • Progress to full ankle ROM 
  • Gentle calf stretching after 8 weeks as tolerated; may stretch beyond neutral dorsiflexion after 8 weeks 

Strengthening 

  • Double-leg heel raises 
  • Theraband strengthening 
  • Leg press (light resistance) 
  • Closed-chain strengthening 
  • Step-ups 
  • Mini squats 
  • Balance training 
  • Single-leg stance progression 

Criteria to Progress 

  • Full ROM 
  • Normal gait 
  • Able to perform 20 double-leg heel raises without pain 

 Phase IV: Strengthening (Months 3–6) 

Goals 

  • Restore calf strength 
  • Improve endurance 
  • Improve dynamic balance 
  • Prepare for higher-level activity 

Therapeutic Exercises 

  • Single-leg heel raises 
  • Eccentric calf strengthening 
  • Lunges 
  • Step-downs 
  • Single-leg balance on unstable surfaces 
  • Agility ladder 
  • Plyometric progression (begin around 16–20 weeks if appropriate) 

Running Progression 

Initiate light jogging around 4–5 months if: 

  • Pain free 
  • Full ROM 
  • Near-normal calf strength 
  • Able to perform ≥20 single-leg heel raises 

Phase V: Return to Sport (6–9+ Months) 

Goals 

  • Restore maximal strength and power 
  • Return to unrestricted activities 
  • Prevent reinjury 

Exercises 

  • Sprint progression 
  • Cutting and pivoting drills 
  • Jump training 
  • Sport-specific drills 
  • Single-leg hopping progression 

Return to Sport Criteria 

Patient should demonstrate: 

  • Full ankle ROM 
  • No pain or swelling 
  • Symmetric gait 
  • ≥90–95% plantarflexion strength compared with contralateral side 
  • Successful completion of functional hop and balance testing 
  • Surgeon clearance 

 General Precautions 

  • Avoid aggressive dorsiflexion stretching during the first 8 weeks. 
  • Tendon elongation is associated with persistent weakness; avoid excessive early loading. 
  • Swelling may persist for several months. 
  • Recovery of calf strength commonly continues for 9–12 months after surgery. 
  • Progression should be based on objective function rather than time alone.
