Knee PainPatellofemoral Syndrome, IT Band & Tendinopathy
Patellofemoral syndrome, IT band, patellar tendinopathy, and knee pain in active patients. Often a biomechanical problem, not just a knee problem.
Book Your First VisitThe knee sits between the hip and foot, and it's heavily influenced by both. Weak hips and stiff ankles are common drivers of knee pain. Addressing the knee alone often produces limited results. Assessment needs to cover the whole lower limb. For most mechanical knee presentations, modified training can continue alongside rehabilitation. Stopping entirely is rarely necessary.
Why the knee is rarely just a knee problem
The knee is a hinge joint that sits between the hip and foot, and it's heavily influenced by what happens at both ends of that chain. Weak hip abductors can contribute to the femur tracking inward, increasing load on the medial knee and altering how the kneecap tracks in its groove. Restricted ankle dorsiflexion can produce compensatory movement patterns that stress the knee during squatting, running, and stairs.
This is why combined hip and knee treatment produces better outcomes than knee-focused treatment alone for patellofemoral pain. The knee is where the pain is; the hip or ankle is often where the problem is. Assessment needs to cover the whole lower limb to find the actual driver.
Common causes
- Patellofemoral pain syndrome (PFPS, commonly called runner's knee): pain around or behind the kneecap, often worse going downstairs, squatting, or sitting for long periods. Associated with altered kneecap mechanics, usually related to hip abductor weakness and quadriceps imbalance, and often triggered or aggravated by a sudden increase in training volume. Foam rolling the quad provides temporary relief but the underlying mechanics respond better to targeted strengthening.
- IT band syndrome: lateral knee pain from iliotibial band tension where it crosses the lateral femoral condyle. Common in runners with a rapid mileage increase. The IT band itself doesn't stretch, so foam rolling the band has limited benefit. Hip abductor strengthening is a central component of treatment.
- Patellar tendinopathy: pain at the bottom of the kneecap from tendon overload. Common in volleyball, basketball, and gym athletes. Responds to progressive loading rehabilitation, not rest.
- Pes anserine tendinopathy: medial knee pain that is often confused with meniscal problems. Located slightly below and medial to the joint line.
- Post-surgical rehabilitation: after ACL reconstruction or knee replacement, progressive loading and joint mobilization restore range of motion and function. For ACL reconstruction and knee replacement, physiotherapy is the conventional lead for post-surgical rehabilitation. I work as an adjunct within that team's care plan, within the surgeon's guidelines.
What helps
Treatment combines joint mobilization at the knee, hip, and ankle where restricted, soft tissue work for structures contributing to altered mechanics, and progressive loading rehabilitation that builds the capacity of the affected tissue. The specific program depends on what the assessment finds.
On IT band syndrome
IT band syndrome is often managed with IT band foam rolling and IT band stretching, but the IT band doesn't respond meaningfully to either of these directly. What does work: hip abductor and external rotator strengthening to reduce the hip drop that increases IT band tension, training load management, and hip and knee mobilization where restricted. Address why the IT band is under load, not just the band itself. Research consistently shows that hip abductor weakness and reduced hip abductor strength are characteristic findings in runners with IT band syndrome. A systematic review of conservative treatment approaches found hip abductor strengthening, combined where needed with load management, is effective for resolving IT band syndrome in runners.
How I approach knee pain
The first session assesses hip strength and mobility, knee mechanics, ankle dorsiflexion, foot pronation, and the movement pattern that provokes symptoms, including running gait for runners and cyclists. Acute swelling with a clear mechanism of injury needs imaging to rule out meniscal or ligament damage before treatment proceeds. Gradual-onset anterior knee pain without the features in the red flag section below rarely requires imaging before assessment begins.
For runners and cyclists with a race or event timeline, I'll build the rehabilitation plan around your training rather than defaulting to rest. For most mechanical knee presentations, modified training can continue alongside rehabilitation.
The pattern most common in recreational runners is gradual-onset pain under or around the kneecap, worse on stairs or after longer runs, without swelling and without a specific injury. That presentation is appropriate for assessment here before imaging or specialist referral. For that presentation, hip and knee strengthening together outperform knee strengthening alone for patellofemoral pain.
Patellofemoral pain and IT band syndrome often show meaningful improvement within weeks to months of consistent rehabilitation, though individual timelines vary and longer-standing presentations often take more time. In my clinical experience, patellar tendinopathy is slower: often 3 to 6 months, depending on severity and loading history, because tendon remodelling takes time. Exercise prescription (progressive loading, such as eccentric or heavy slow resistance training) is the core treatment for patellar tendinopathy; manual therapy is adjunctive.
Knee pain often has identifiable mechanical drivers (in the hip, the foot, or the movement pattern) that are addressable without imaging. If you'd like to talk through your situation before booking, get in touch.
When to seek care promptly
See a doctor if you have:
- Acute knee swelling after a twisting injury or direct impact
- A sensation of locking, giving way, or the knee catching
- Significant instability or inability to weight-bear
- Knee pain with fever, warmth, or unexplained joint swelling that is rapidly worsening (possible infection or inflammatory arthritis)
- Knee pain in a child or adolescent that worsens at night, doesn't improve with rest, or involves a palpable swelling (warrants urgent medical assessment)
- Calf pain, swelling, or redness following surgery or prolonged immobilization (possible DVT: seek emergency care)
These warrant imaging and possible orthopaedic review. Gradual-onset knee pain without these features is appropriate for conservative assessment and management.

Common questions
Pain on descent rather than ascent is a classic pattern for patellofemoral pain, where the kneecap isn't tracking well under load. Going downstairs increases the load on the quadriceps (the thigh muscles that control the descent) and compresses the kneecap into its groove, which is provocative when the mechanics are off or the cartilage is inflamed. This pattern guides the assessment and helps distinguish patellofemoral pain from a meniscal problem or other issue inside the joint, which tends to behave differently under load.
Not necessarily. Degenerative tears are those found incidentally on MRI and not associated with mechanical symptoms such as locking or catching. They are common findings in imaging of people over 35 who may have no significant symptoms at all. For that presentation, research consistently shows conservative management produces outcomes comparable to APM (arthroscopic partial meniscectomy) at 12 months. Physical therapy alone produces similar outcomes to APM combined with physical therapy. Five-year follow-up data found no sustained benefit from APM and a slightly higher rate of progression to osteoarthritis. Traumatic tears in younger patients from a specific incident have a higher surgical rate, but even then, a trial of conservative care is often reasonable first. I'll assess which category your presentation falls into and give you an honest view of what the evidence says for your situation.
It can be treated, rest alone doesn't address the underlying cause. IT band syndrome is associated with hip abductor weakness and altered running or cycling mechanics, not by the band itself being too tight (it can't be stretched significantly). Treatment focuses on hip strengthening, load management, and correcting the movement pattern that's provoking it. Foam rolling the IT band gives temporary relief but doesn't change the underlying mechanics. I'll assess what's driving it and build a rehabilitation plan accordingly.
Yes, depending on what's persisting. Post-surgical knee pain at 6 months is often related to quad inhibition, altered movement patterns, scar tissue sensitivity, or adjacent joint dysfunction, not necessarily a sign that something went wrong structurally. I'll assess what's contributing and work alongside your surgical team's rehabilitation plan. If you're not already working with a physiotherapist post-surgery, that's typically the right primary referral. If I think something warrants reassessment by your surgeon, I'll tell you directly.
Patellofemoral pain with identified mechanics issues often shows meaningful improvement within weeks to months of consistent rehabilitation when combined with targeted hip and quad strengthening, though individual timelines vary and longer-standing presentations often take more time. IT band syndrome often follows a similar rehabilitation arc when training load is managed alongside hip strengthening, though individual timelines vary. Degenerative meniscal presentations take longer. In my clinical experience, often 8–12 weeks to show consistent change. Post-surgical rehabilitation timelines depend on what was done and how far along healing is. I'll give you a realistic estimate based on your presentation after the first visit. If you have a race or event coming up, that timeline factors directly into how we sequence the rehabilitation plan.
