If you have laced up for a run along the Kay Park, round the Dean Castle grounds, or out towards Irvine beach and felt that nagging ache around or to the side of your kneecap, you are in good company. Knee pain is one of the most common complaints we see from runners at the clinic, whatever the season, and the good news is that most cases respond really well to the right kind of physio.
Two conditions come up again and again: patellofemoral pain syndrome (better known as "runner's knee") and iliotibial band, or ITB, syndrome. They can feel similar at first. Both tend to flare up during or after a run and settle with rest, but they are caused by different things and respond best to slightly different approaches. Here is a plain-English guide to both.
Runner's Knee (Patellofemoral Pain Syndrome)
Runner's knee shows up as an ache just behind or around the front of the kneecap. It is usually worse going downstairs, after sitting for a long time with your knee bent, or towards the end of a longer run. You might also notice some crackling or grinding around the kneecap. On its own, that is not something to worry about.
This is genuinely one of the most common knee problems around, particularly in active teenagers and adults, and research suggests roughly half of people recover within a few months while others find it lingers or comes back if the underlying cause is not addressed (InformedHealth.org / IQWiG, 2024). It tends to develop from a mix of factors: training load ramping up too quickly, weaker thigh and hip muscles, and sometimes how the foot and leg move together when you run. A Cochrane review of 31 trials involving over 1,600 people found consistent (if still fairly low-certainty) evidence that structured exercise therapy leads to a meaningful reduction in pain and better function, both in the short term and further down the line, and that combining hip strengthening with knee strengthening tends to outperform knee exercises alone (van der Heijden et al., Cochrane Database of Systematic Reviews, 2015).
In other words: your hips matter just as much as your knees when it comes to sorting this out.
ITB Syndrome
Iliotibial band syndrome feels different. It is typically a sharper, more localised pain on the outside of the knee, often appearing at a fairly predictable point in a run (many runners can tell you almost exactly which mile it starts). The IT band is a thick strip of connective tissue running from the hip down the outside of the thigh to just below the knee, and when it is repeatedly loaded, through higher mileage, hill running, or a sudden jump in training, the tissues around the knee can become irritated.
A 2024 systematic review looking specifically at conservative treatment for ITB syndrome in runners found that hip abductor strengthening was the standout intervention, forming part of the majority of successful treatment programmes, with pain reductions ranging widely from around 27% up to full resolution over two to eight weeks of consistent work (Sanchez-Alvarado et al., Frontiers in Sports and Active Living, 2024). Interestingly, combining strengthening with other approaches, such as manual therapy, gait adjustments, or shockwave therapy in some cases, tended to work better than strengthening alone, with combined approaches achieving around 71% pain reduction on average compared to roughly 61% for single interventions.
When to See a Physio
You do not need to grit your teeth and run through either of these, and you do not need a GP referral to get seen at Jordan Physiotherapy Ayrshire, so there is no reason to wait it out for weeks before getting help. It is worth booking in if:
- The pain is affecting your usual training and is not easing with a few days' rest
- It has been nagging for more than two to three weeks
- You have noticed swelling, locking, or your knee giving way
- You have had a go at resting and stretching and it just keeps coming back once you restart running
Getting an accurate diagnosis matters here, because while runner's knee and ITB syndrome can look similar from the outside, the rehab plan that actually resolves them differs. Treating the wrong one, or treating symptoms without addressing training load and strength, is a common reason knee pain becomes a repeat visitor.
What Treatment Looks Like
At the clinic, sorting out knee pain in runners usually starts with a proper look at how you move, not just the knee itself, but your hips, foot mechanics, and how your current training load compares to what your body is actually adapted to. From there, treatment typically includes:
- A targeted strengthening programme focused on the hip and thigh muscles (the evidence above is pretty consistent that this is where the real gains are made)
- Hands-on treatment to ease irritated, tight tissue and support your range of movement
- Practical advice on adjusting your training, including mileage, hills, footwear, or rest days, so you are not just treating the pain but the cause
- A gradual, structured return to running so you build confidence back into the knee rather than jumping straight back to where you left off
Simple Self-Care Tips in the Meantime
While you are waiting to get seen, or if things are mild, a few sensible steps can help: ease off the mileage rather than stopping altogether if you can manage pain-free movement, avoid hills and cambered pavements for a week or two, and keep some gentle hip and glute strengthening ticking over. Things like side-lying leg raises or clamshells are a reasonable starting point. Ice after activity can take the edge off discomfort. What is best avoided is pushing through sharp pain hoping it will "run off". That is usually how a mild niggle turns into weeks off training.
