Running Gait Case Study for a Safer Return

A runner can complete most of a 5 km comfortably, then feel a familiar ache build through the outside of the ankle or beneath the kneecap as they slow down. They may have changed trainers, stretched more, or taken several days off, yet the problem returns when training resumes. This running gait case study shows why looking beyond the painful area can be valuable when running pain is persistent or keeps recurring.

The case is illustrative and reflects a common type of presentation seen in podiatric biomechanics. Every runner has different training demands, injury history, anatomy and recovery capacity, so assessment and treatment should always be individual.

The runner and the problem

Our runner was a 38-year-old recreational runner training three times a week. She had gradually increased her weekly mileage while preparing for a half marathon. Her main concern was pain on the outside of her right knee, beginning after approximately 25 minutes of running and becoming more noticeable on downhill sections.

Walking was comfortable. She could cycle and use the gym with little difficulty, but running had become frustrating and unpredictable. She had reduced her mileage twice, only for the pain to return once she tried to build back up. Her goal was not simply to get through the race. She wanted to run regularly without worrying about the next flare-up.

Pain around the knee does not automatically mean that the knee is the only area needing attention. During running, the foot, ankle, lower leg, hip and trunk work together to manage repeated impact and forward movement. A change in control or loading at one part of that chain can alter the demands placed elsewhere.

What a running gait case study can reveal

A running gait assessment is not about deciding that there is one perfect running style. Runners vary widely, and many gait features are normal variations rather than faults to correct. The clinical question is more useful: does the way this person is moving, combined with their training load and physical capacity, make their symptoms more likely?

The assessment began with a detailed history. We discussed when symptoms started, recent mileage changes, terrain, pace, footwear rotation, previous injuries, sleep, work demands and strength training. A rapid increase in distance or intensity can be enough to exceed the body’s current capacity, even where a runner’s technique has not changed.

A physical examination then considered joint movement, muscle strength, balance, tenderness and the ability to control the leg during tasks such as a single-leg squat and step-down. The runner had reduced control of the pelvis and thigh on the right during these activities, alongside limited ankle dorsiflexion. In simple terms, the ankle had less available movement as the shin moved forward over the foot.

Her running was observed at a comfortable pace. Video can be useful here, particularly when it allows movement to be reviewed carefully, but it is only one part of the picture. The assessment noted that as fatigue developed, her right knee moved inwards relative to the foot and her pelvis dropped slightly on the opposite side. Her stride also became a little longer when running downhill, increasing braking forces through the leg.

None of these findings alone diagnosed the cause of pain. Taken together with the history and examination, however, they suggested that the outer knee was being asked to absorb more load than it could currently tolerate.

Why a single frame is not enough

It is tempting to focus on one image of a foot rolling inwards or a knee turning in. That can be misleading. Movement is dynamic, and an apparent alignment issue may be a normal response to speed, fatigue, surface or an individual’s anatomy.

For this runner, the more meaningful finding was the pattern: symptoms appeared at a predictable point in a run, worsened with downhill running, and coincided with reduced control as fatigue accumulated. A good gait assessment connects what is seen with what the runner feels and what they need to do.

Building a treatment plan around load and capacity

The plan did not involve telling the runner to stop running indefinitely or trying to force her into a completely different gait. Both approaches can be unhelpful. Extended rest may reduce symptoms temporarily, but it does not necessarily rebuild the capacity needed for a return to training. Major technique changes can also shift stress to a new area if introduced too quickly.

Instead, treatment focused on reducing aggravation while retaining fitness where possible. Her running distance was reduced to a level that did not produce significant pain during or after the session. Downhill routes were avoided initially, and cycling was used for additional aerobic exercise.

A progressive strength programme targeted hip control, calf capacity and single-leg stability. Exercises were selected because they related to the findings of the assessment and could be performed consistently, not because there is one exercise that suits every runner with knee pain. The programme was progressed as control and tolerance improved.

We also worked on ankle mobility and discussed a small adjustment to running cadence. A modest increase in step rate can shorten overstriding for some runners and may reduce braking forces. It is not a universal prescription, and the change was introduced gradually. The runner was encouraged to focus on a light, comfortable rhythm rather than trying to consciously control every part of her stride.

Footwear was reviewed too. Her trainers were not inherently unsuitable, but the pair used for longer runs was worn and had little remaining midsole resilience. Replacing them formed part of the plan. Footwear choice should reflect comfort, training needs and the individual runner, rather than marketing claims or a label such as neutral or stability shoe.

When might insoles be considered?

Insoles or custom orthoses can be helpful for some runners when foot mechanics, symptoms and footwear interact in a way that changes loading higher up the leg. They are not automatically required because a foot appears to pronate or because pain occurs during running.

In this case, an insole was not the first intervention. The runner’s symptoms improved with load adjustment, strength work and footwear replacement. If progress had stalled, or if foot and ankle findings had suggested a clearer contribution, an orthotic option could have been considered as one tool within a broader rehabilitation plan.

Progress was measured beyond pain alone

At the first review, the runner reported that she could run for 35 minutes on flat ground before noticing only mild discomfort. Her single-leg control had improved, and she was managing the strength programme without symptom flare-ups. The next step was not to return immediately to previous mileage. It was to build duration gradually, then reintroduce gentle hills before adding faster sessions.

By monitoring symptoms during the run, later that day and the following morning, she could distinguish a manageable response from a flare-up that indicated excessive load. Mild awareness that settled quickly may be acceptable in some rehabilitation plans. Sharp pain, altered running mechanics, swelling, worsening symptoms or pain that lingers should prompt a review of the activity and, where needed, further clinical advice.

This approach recognises that recovery is rarely linear. A demanding week at work, poor sleep, a hard gym session or an unexpectedly hilly route can affect tolerance. The aim is not perfection. It is to make training decisions with enough information to keep moving forward safely.

What runners can take from this case

Persistent running pain deserves more than repeated rest and guesswork. A biomechanical assessment can help establish whether training load, strength, joint movement, footwear, running mechanics or a combination of factors may be contributing. It can also identify when a runner needs assessment from another health professional or further investigation.

A gait assessment is most useful when it leads to practical decisions: what to modify now, what to strengthen, whether footwear or insoles may have a role, and how to progress back to the running that matters to you. For runners in London, Surrey, Essex or around Romford, Footporium Podiatry can assess lower-limb pain in the context of the whole movement pattern.

If every attempted return to running ends at the same point of pain, that pattern is useful information. It is a reason to assess the load your body is managing, rather than simply pushing through or giving up the activity you enjoy.
