What is the recommended management for a patient with swelling and protrusion on the anterior horn repair site after leg press, with no mechanical symptoms or pain, that resolves after cessation of activity?

Management of Localized Swelling at Anterior Horn Repair Site After Leg Press

Continue your leg press exercises with appropriate load modification while monitoring the swelling response, as this represents normal tissue remodeling rather than a pathological process. 1

Understanding the Clinical Picture

Your presentation is consistent with expected postoperative tissue adaptation rather than repair failure:

• Reactive synovitis from mechanical stress on healing tissue during loaded exercises like leg press occurs as a normal physiological response 1
• Exercise-induced swelling that resolves with rest indicates ongoing tissue remodeling and incomplete healing adaptation, which is expected during the recovery timeline 1
• Most patients experience resolution of this exercise-induced swelling by 6-8 weeks postoperatively as the repaired tissue matures and adapts to mechanical loads 1

The absence of pain and mechanical symptoms is reassuring and suggests the repair integrity remains intact 1

Recommended Activity Modification Strategy

Continue Progressive Loading

• Maintain closed kinetic chain exercises such as leg press and squats, as these are appropriate for your postoperative timeline 1
• These exercises are safe and beneficial for tissue remodeling when performed within appropriate parameters 2, 3

Load Management Parameters

• Reduce load or volume if swelling persists beyond 24 hours after exercise, as this indicates excessive mechanical stress on healing tissue 1
• The key metric is not whether swelling occurs, but rather how long it takes to resolve 1
• Swelling that resolves within hours to one day after exercise cessation is acceptable and expected 1

Adjunctive Measures

• Apply cryotherapy and compression immediately post-exercise to minimize reactive inflammation 1
• Cryotherapy is inexpensive, easy to use, has high patient satisfaction, and is rarely associated with adverse events 3
• Elevation after exercise sessions can further facilitate resolution 4

Critical Monitoring Parameters

You should seek urgent evaluation if any of the following develop:

• Progressive worsening of swelling intensity or duration despite appropriate activity modification 1
• Swelling becomes constant rather than exercise-related, suggesting possible repair failure 1
• Pain intensity increases despite activity modification and anti-inflammatory measures 1
• Development of mechanical symptoms such as catching, locking, or giving way 2

Expected Timeline

• Minor physiological swelling is normal and expected after any surgical repair, typically resolving within the first week with rest and elevation 1
• Persistent localized swelling with loading that you're experiencing indicates ongoing tissue remodeling, which is a normal phase of healing 1
• Resolution typically occurs by 6-8 weeks postoperatively as collagen remodeling progresses and tissue tensile strength increases 1

Common Pitfalls to Avoid

• Do not completely cease loading activities based solely on transient swelling, as early progressive mobilization is needed to optimize regeneration and recovery 4
• Avoid excessive immobilization, as the duration should be limited to allow scar tissue of sufficient strength while preventing stiffness 4
• Do not ignore persistent swelling beyond 24 hours after exercise, as this requires load reduction 1

The key principle is progressive loading within the limits of acceptable tissue response, where transient swelling that resolves quickly is acceptable, but persistent swelling requires modification 1, 4
