Weight-Bearing and Rehabilitation After Peroneus Longus Tendon Graft Harvest

For peroneus longus tendon donor site surgery, allow immediate full weight-bearing with free ankle mobility and no orthosis, as the donor site itself requires no specific restrictions beyond those dictated by the recipient graft site reconstruction. 1

Donor Site Management

The peroneus longus tendon harvest creates minimal donor site morbidity that does not require protective weight-bearing restrictions. The key principle is that the ankle joint tolerates immediate mobilization after graft harvest 1. This differs fundamentally from recipient site protocols (ACL, extensor mechanism, etc.) which have their own specific restrictions.

Immediate Postoperative Period (Week 0-2)

  • Full weight-bearing as tolerated immediately - no crutches required for the donor ankle itself
  • Free ankle range of motion - no immobilization or bracing needed
  • No ankle orthosis required 1
  • Monitor for:
    • Incisional pain at the lateral ankle (typically minimal)
    • Swelling (address with elevation, ice)
    • Any signs of peroneal nerve traction injury (rare)

Early Recovery (Weeks 2-6)

The donor ankle demonstrates preserved function with no clinically significant morbidity:

  • Ankle function remains intact as measured by AOFAS and FADI scores 2, 3
  • Ankle range of motion is preserved 2
  • No sports restrictions related to the donor site 2
  • Patients experience less pain and dysfunction compared to hamstring donor sites 2

Critical Distinction: Recipient Site Dictates Overall Protocol

Your rehabilitation timeline is determined entirely by what reconstruction you're performing, not by the peroneus longus harvest. The donor site adds no additional restrictions. For example:

If Performing ACL Reconstruction:

  • Follow standard ACL protocols: immediate weight-bearing with correct gait pattern, no pain/effusion 4
  • Begin isometric quadriceps exercises week 1 4
  • Start closed kinetic chain exercises week 2 4
  • Initiate open kinetic chain exercises week 4 (90-45° ROM) 4
  • Continue rehabilitation 9-12 months for return to sport 4

If Performing Extensor Mechanism Reconstruction:

  • Use brace with gradual weight-bearing progression 5
  • Expect longer immobilization (6-8 weeks typical for extensor mechanism repairs)
  • Progress to full weight-bearing as extensor mechanism healing allows 5

If Performing Peroneal Tendon Repair (Recipient Site):

  • Median immobilization 6-8 weeks for primary repairs 6
  • Trend toward earlier range of motion (within 4 weeks) 6
  • Adjust protocol to specific surgical technique used 6

Evidence Quality and Nuances

The evidence for peroneus longus donor site management is remarkably consistent but comes primarily from recent research rather than formal guidelines. Multiple studies demonstrate that the peroneus longus harvest site requires no special protection 1, 7, 2, 3.

One study showed earlier mobilization and return to work when using peroneus longus grafts for ACL reconstruction compared to hamstring grafts, though this reflected combined effects of both graft choice and surgical technique 7. The key finding: no ankle dysfunction or restrictions were attributed to the donor site itself.

Common Pitfalls to Avoid

  1. Don't unnecessarily restrict the donor ankle - there is no evidence supporting immobilization or protected weight-bearing for the harvest site alone
  2. Don't confuse donor site and recipient site protocols - patients and therapists may mistakenly apply recipient site restrictions to the donor ankle
  3. Don't overlook rare peroneal nerve traction - while uncommon, monitor for delayed peroneal muscle response or weakness
  4. Don't assume ankle instability - chronic ankle instability is a contraindication to harvest 1, but if harvested appropriately, the remaining posterior half of the tendon maintains ankle stability

Return to Activities

  • Return to work: Determined by recipient site reconstruction, not donor site 7
  • Return to sport: No ankle-specific limitations from donor site; follow recipient site timeline 2
  • Long-term function: Studies show no clinically significant ankle morbidity at 1-2 year follow-up 2, 3

The peroneus longus donor site is essentially a non-issue in your rehabilitation planning - focus your restrictions and progression entirely on the reconstructed structure, allowing the ankle to move freely from day one.
