Knee arthroscopy encompasses a range of procedures: diagnostic arthroscopy, partial meniscectomy, meniscal repair, microfracture (cartilage restoration), lateral release, and ACL reconstruction. Each has a different post-operative weight-bearing protocol and a different role for a walking cane. The common error is applying the same walking aid protocol to all knee arthroscopies -- when in fact a partial meniscectomy patient may be fully weight-bearing same day, while a microfracture patient is non-weight-bearing for 6-8 weeks.
Knee Arthroscopy Procedures and Walking Aid Requirements
| Procedure | Weight-Bearing Protocol | Walking Aid | Cane Duration |
|---|---|---|---|
| Diagnostic arthroscopy only | Full weight-bearing from day 1 | Cane optional; for pain and confidence | 3-7 days |
| Partial meniscectomy (meniscal resection) | Full weight-bearing from day 1 or day 2 | Cane contralateral; for antalgic limp and confidence | 1-2 weeks |
| Meniscal repair (meniscal suture) | Partial weight-bearing in locked brace 6-8 weeks; no deep flexion | Crutches 6-8 weeks; cane from 8-12 weeks | 2-4 weeks (cane phase) |
| Microfracture (cartilage restoration) | Non-weight-bearing 6-8 weeks (critical for clot maturation) | Crutches; frame; cane introduced at 8-10 weeks | 4-8 weeks (cane phase) |
| ACL reconstruction (graft) | Full weight-bearing from day 1 (contemporary protocol); brace for 6 weeks | Crutches first 1-2 weeks; cane weeks 2-6 if needed | 2-4 weeks |
| Lateral release (MPFL repair) | Full weight-bearing with brace | Cane for 2-3 weeks; knee brace primary | 2-3 weeks |
The Microfracture Exception: Why Non-Weight-Bearing Is Mandatory
Microfracture involves creating small holes in the subchondral bone to stimulate fibrocartilage formation (a blood clot that matures into fibrocartilage at the defect). Any weight-bearing during the first 6-8 weeks disrupts the forming clot and destroys the repair. A cane is completely insufficient for microfracture post-operatively -- crutches or a frame providing true non-weight-bearing are required. A cane is introduced only as a transition aid from crutches to independent walking at 8-12 weeks.
ACL Reconstruction: Contemporary vs Traditional Protocol
Traditional ACL reconstruction protocols (1990s-2000s) required non-weight-bearing for 1-4 weeks. Contemporary accelerated protocols allow full weight-bearing from day 1 or day 2 (the graft does not bear load -- the brace does). Under accelerated protocols, crutches are used for 1-2 weeks primarily for pain and confidence, with a cane transition at 2-4 weeks. By 4-6 weeks, most ACL patients progress to independent walking without aids.
