What Causes Knee Pain Going Downstairs?
Descending stairs requires the quadriceps to work eccentrically — contracting while lengthening — to control the lowering of your body weight, a demand that produces far greater tendon and cartilage stress than concentric stair climbing. The patellofemoral joint experiences compression forces of three to four times body weight during stair descent, which is why conditions that might be silent on flat ground or stair ascent become intensely painful going down. The knee must also work as a stable, precise hinge while the body's centre of gravity shifts forward, meaning any instability from weak hip muscles or ligament laxity is immediately amplified.
Common Conditions That Cause This Symptom
- Patellofemoral Pain Syndrome: Eccentric loading during stair descent compresses an already-irritated kneecap against the femoral groove, producing sharp anterior knee pain that is consistently worse going down than up.
- Patellar Tendinopathy: The patellar tendon is under peak eccentric load during controlled descent; degenerated tendon tissue is highly sensitive to this demand and produces pain just below the kneecap.
- Chondromalacia Patellae: Softening and early breakdown of the cartilage on the back of the kneecap creates pain precisely during the high-compression eccentric phase of stair descent.
- ACL or Posterior Capsule Laxity: Subtle instability caused by ligament insufficiency becomes most apparent on stair descent when the knee must control a large flexion moment, leading to pain and a sense of the knee 'going through'.
Warning Signs — When to See a Physiotherapist
If stair descent is becoming a significant daily limitation or you are starting to avoid certain stairs or activities, professional assessment is strongly recommended sooner rather than later.
- Pain lasting more than 2 weeks without improvement
- A sense that the knee will give way on descending steps
- Swelling appearing on the outer or front of the knee after stair use
- Numbness, tingling or weakness alongside the pain
- Pain that disturbs sleep
How Physiotherapy Treats This
Eccentric quadriceps exercises — specifically step-down protocols — progressively reload the patellar tendon and cartilage at controlled intensities to drive adaptation and reduce pain. Hip abductor and external rotator strengthening corrects the dynamic valgus collapse that overloads the patellofemoral joint during eccentric stair use. Patellar taping and joint mobilisation provide immediate symptomatic relief while the strengthening programme takes effect.
What to Expect at Your First Assessment
At Realign Rehab Clinic in Faridabad, Dr. Vaishali Suri will carry out a step-down movement screen, patellar tracking assessment, eccentric quad strength testing and a functional stair analysis to observe the exact breakdown in your movement pattern. This pinpoints the exact cause so a personalised treatment plan can be created.
Self-Care Tips While You Wait
- Hold the handrail firmly on stair descent to partially offload the knee until your assessment
- Practise slow, controlled single-leg step-downs from a low step to begin building eccentric quad strength without excessive pain
- Apply a patellar tendon strap (available at most pharmacies) when using stairs to reduce tendon load temporarily
- Avoid running downhill or taking stairs quickly, as speed dramatically increases eccentric knee forces and will worsen the underlying condition
Frequently Asked Questions
Why does my knee hurt more going downstairs than upstairs?
Going downstairs demands an eccentric quad contraction that loads the patellofemoral joint and patellar tendon with three to four times body weight — significantly more than the concentric demand of stair ascent. This is why conditions like patellofemoral syndrome and patellar tendinopathy are almost always worse on the way down. Targeted eccentric rehabilitation at Realign Rehab Clinic resolves the problem in the majority of cases without surgery.
Can physiotherapy fix this without surgery?
In most cases, yes. Physiotherapy addresses the root mechanical cause. Dr. Vaishali Suri uses evidence-based manual therapy, targeted exercises and electrotherapy at Realign Rehab Clinic, Faridabad.
How many sessions will I need?
Most patients see improvement within 4-6 sessions. A personalised programme is designed after your initial assessment — call +91 9818185589 to book.
