Weight‑Bearing Guidelines After Complex Knee and Ankle Reconstruction

General Recommendations (American Physical Therapy Association)

• The American Physical Therapy Association advises that early weight‑bearing may be used only when tolerated, requiring a progressive rather than immediate load in complex postoperative cases. 1, 2

Criteria Required Before Full Weight‑Bearing (British Journal of Sports Medicine 2016)

• Full weight‑bearing may be initiated only after the patient demonstrates:

Partial Weight‑Bearing Progression (British Journal of Sports Medicine 2016)

• Weeks 0‑2: (not cited – omitted).
• Weeks 3‑6: Progress to 25 %–50 % of body weight (partial load) provided there is no pain, effusion, or temperature rise. 3
• Bilateral crutch use is recommended to distribute load evenly and preserve a symmetric gait pattern. 3

Objective Criteria for Advancing Load (British Journal of Sports Medicine 2016)

• Advancement to a higher load level is permitted when all of the following are met:

Early Knee Mobilization and Quadriceps Activation (British Journal of Sports Medicine 2020)

• Initiating knee range‑of‑motion exercises within the first postoperative week is critical for preserving motion and reducing pain, but must be performed without weight‑bearing. 1, 7, 8, 9
• Quadriceps isometric exercises can be started from the first week as long as they are pain‑free. 3

Ankle Lateral Ligament Partial Tear – Independent Load Restriction (American Physical Therapy Association)

• A partial tear of the lateral ankle ligament complex constitutes a separate indication for weight‑bearing restriction; assistive devices such as crutches are recommended according to APTA guidelines. 2, 4

Documentation of Weight‑Bearing Protocol (British Journal of Sports Medicine 2016)

• Clinical records should explicitly state the percentage of body weight allowed at each phase and list the objective criteria (pain, effusion, gait quality, exercise performance) that must be satisfied before progressing. 3
