Read on to learn the exact red flags to watch for and the fast, practical ways to start feeling better.
Quick take
Ankle and knee pain often show up together because your joints share the workload. When one stiffens up, the other works overtime. First, notice the pattern. Then, act early so small issues don’t turn into big ones.
If ankle and knee pain lingers more than a week, schedule a physical therapy evaluation
If swelling keeps coming back after normal activity, get checked
If stairs, squats, or long walks feel shaky or painful, don’t wait
If you felt a pop, heard a click with catching, or now feel unstable, move sooner rather than later
If symptoms ease with warm-up but return after sitting, you likely need targeted mobility and strength
At Physiopros Performance Rehab in Parsippany, NJ, we assess how you move, treat the root cause, and map a simple plan you can follow. This guide shows the red flags to watch for and the next steps to get you back to pain-free motion.
Why ankles and knees team up
Your body moves as a chain. When the ankle gets stiff, the knee often pays the price. Likewise, when the hip is weak, the knee twists or collapses inward, and the ankle strains to keep up.
Old ankle sprains can limit motion and load the knee
Tight calves and limited dorsiflexion change squat and step mechanics
Weak hips and poor balance push extra stress into both joints
Guessing and “working through it” usually delays real progress
Red flags to book a physical therapy evaluation now
These signs mean it’s time to see a physical therapist soon, especially if you live or work near Parsippany, NJ.
Pain lasts more than 7–10 days despite rest and simple care
Repeated swelling after regular activity or gym sessions
Instability or giving way on stairs, hills, or uneven ground
Clicking, catching, or a sense of blockage with squats or steps
Pain that shifts between joints (ankle today, knee tomorrow)
Trouble with everyday tasks: rising from a chair, long walks, carrying groceries
After a minor twist or tweak, ankle and knee pain keeps returning
Red flags that mean urgent care or ER first
If you notice any of these, seek medical care first. After clearance, physical therapy helps restore motion and strength.
Major trauma, visible deformity, or inability to take four steps
Sudden pop with rapid swelling within a few hours
Fever, chills, and a hot, very swollen joint
Numbness, tingling, or new foot drop
Calf pain with warmth, redness, or unexplained swelling
What a physical therapist will do
A thorough evaluation points treatment in the right direction. Expect a clear plan and actionable next steps at Physiopros Performance Rehab.
Conversation: history, goals, aggravating and easing factors
Movement screen: squat, step-down, single-leg balance, gait check
Range and strength: ankle dorsiflexion, calf strength, hip control
Targeted treatment: manual therapy, mobility work, exercise loading
Game plan: visit frequency, home program, and return-to-activity timeline
Simple self-checks you can try today
Use these quick screens to learn what your body needs. If any trigger ankle and knee pain, note it and share at your visit.
Wall ankle test: knee to wall without lifting the heel (compare sides)
Step-down control: slow, quiet tap from a low step (no wobble or knee collapse)
Single-leg balance: 20–30 seconds eyes open on each leg
Comfortable squat: heels grounded, knees track over toes without pinching
Smart care until your appointment
Keep things moving without making symptoms worse. Small, steady steps beat big swings.
Short walks and gentle range of motion a few times a day
Swap impact for cycling or pool work if pounding flares symptoms
Use ice or heat based on what feels better for you
Wear supportive, broken-in shoes you can keep on all day
Prevention once you’re feeling better
Build capacity so ankle and knee pain doesn’t keep coming back.
Progress activity in small weekly steps instead of weekend spikes
Keep a quick routine: calf and hip mobility, balance, and strength
Rotate shoes and replace worn-out pairs on schedule
Plan recovery days after long runs, hikes, or games
Revisit your form for squats, lunges, and step-downs

FAQ: Ankle and knee pain
Do I need an MRI before physical therapy for ankle and knee pain?

Can I keep running or working out with ankle and knee pain?
Often yes, with adjusted volume and intensity. A physical therapist will map a graded plan.
How many visits does it take to feel better?
Many feel change in 2–4 visits; full resolution depends on strength, mobility, and activity goals.
Will a brace or sleeve help ankle and knee pain?
Sometimes, short term. The goal is to rely on strength, balance, and good mechanics.

A physical therapy screen checks training load, footwear, and movement patterns that affect both limbs.
