Knee pain is the second most common musculoskeletal complaint (after back pain) in adults. Most people with knee pain do not have a confirmed diagnosis when they first consider a walking cane -- they have pain that limits walking and want relief. The good news: the decision to use a cane does not require a diagnosis. The indication is functional, not diagnostic.
Common Causes of Knee Pain Affecting Walking
- Knee osteoarthritis (most common in adults over 45; medial joint line pain; worse with stairs and prolonged walking)
- Patellofemoral pain syndrome (anterior knee pain; worse with stairs and prolonged sitting; younger active adults)
- Meniscal tear (medial or lateral joint line; pain with twisting; locking or giving way)
- Ligamentous injury (MCL, LCL; lateral or medial pain after injury; may have instability)
- Baker cyst (posterior knee swelling and tightness; pain with full flexion)
- Prepatellar or infrapatellar bursitis (anterior knee swelling and pain; worse with kneeling)
- Osgood-Schlatter disease (adolescents; tibial tuberosity pain; worse with activity)
Cane Placement for Undiagnosed Knee Pain
The universal rule applies: cane in the hand opposite the painful knee. This reduces knee joint reaction force through the hip abductor offloading mechanism. A cane contralateral to the painful knee reduces medial compartment loading, which is the most commonly affected area in knee OA, and reduces overall knee joint reaction force from 3-4x body weight to approximately 2-3x body weight during walking.
Symptoms That Warrant Investigation Before Cane-Only Management
| Knee Symptom | Concern | Action |
|---|---|---|
| Knee giving way or locking | Ligament rupture or loose body; may need surgery | Orthopaedic assessment before relying on cane alone |
| Hot, swollen knee with fever | Septic arthritis (emergency) | Urgent hospital presentation; do not treat with cane |
| Severe acute knee pain after injury | Fracture; ligament rupture | X-ray; do not weight-bear without imaging |
| Night pain waking from sleep; no activity relationship | Tumour; infection; inflammatory arthritis | GP assessment; do not assume mechanical cause |
| Gradual onset; worse with activity; improving with rest | Likely mechanical; OA or overuse | Cane appropriate empirically; physiotherapy |
The Cane as a Diagnostic Indicator
Paradoxically, a cane can help confirm the diagnosis. If a contralateral cane significantly reduces pain during walking, the pain is loading-related and mechanical in origin (OA, cartilage, meniscal). If the cane makes no difference to walking pain, the pain source may be non-loading (inflammatory, referred from spine, vascular). This observation is not diagnostic but is a useful clinical signal that patients can report to their physiotherapist or GP.
