ACL Injury: Your Options

A summary to help guide your conversation with your orthopedic surgeon and rheumatologist.

Option 1 — Surgery (Reconstruction)

Advantages

  • Restores rotational stability in the knee

  • Better outcome for cutting and pivoting sports

  • Reduces risk of further joint damage from instability episodes

Drawbacks

  • 9–12 month recovery minimum

  • Risks include infection, stiffness, and graft failure

  • Surgical stress can trigger autoimmune flares

  • Does not eliminate long-term arthritis risk

Option 2 — Conservative Management (PT Only, No Surgery)

Advantages

  • No surgical or anesthesia risks

  • Avoids complications from pausing immunosuppressant medications

  • Works well for many people in their 40s with lower activity demands

  • Strong quad and hamstring strength can compensate significantly

Drawbacks

  • Instability episodes (knee giving way) can cause secondary damage to the meniscus and cartilage

  • Not ideal for high-demand sports involving cutting or pivoting

  • Some people don't adapt naturally ("non-copers")

If Surgery — Graft Options

Cadaver (Allograft) Tissue from a donor. No harvest site recovery needed. Slightly higher re-tear rate than autograft, but often well-suited for patients in their 40s with lower athletic demands. May be preferable when autoimmune conditions could compromise healing at a harvest site.

Your Own Tissue (Autograft) Typically taken from the patellar tendon, hamstring, or quad tendon. Gold standard for younger, high-demand athletes. Adds a second recovery site. Healing reliability may be reduced with autoimmune conditions.

Autoimmune — Important Considerations

This is the most significant factor in your decision and should be front and center in any surgical discussion.

  • Autoimmune conditions affect tissue repair at a fundamental level — healing is often slower and less predictable

  • Infection risk is higher, especially if you're on immunosuppressants (methotrexate, biologics, steroids)

  • Many rheumatologists recommend pausing certain medications around surgery, which carries its own risks

  • Surgical stress and anesthesia can trigger flares

  • Some autoimmune conditions directly affect connective tissue quality

  • For these reasons, conservative (non-surgical) management becomes a more attractive option — the risk/benefit ratio for surgery narrows considerably

Questions to Bring to Your Doctors

  • Am I having true instability episodes, or is the knee stable but painful?

  • Is there meniscus damage involved? (This often changes the recommendation toward surgery)

  • How do my specific autoimmune conditions affect surgical healing?

  • Would my rheumatologist need to modify my medications around surgery, and what are the risks of that?

  • Based on my activity goals, am I a good candidate for PT-only management?

Key Takeaway

Your rheumatologist and orthopedic surgeon need to make this decision together — not in separate conversations. The autoimmune piece is significant enough that both doctors should be aligned before any surgical decision is made.
