Understanding the 5 Common Lower Limb Tendon Conditions
A sore knee after climbing a few flights of steps, aching around the ankle after a longer walk in the park, or a heel that becomes more sensitive after exercise may all be described as tendonitis. Even so, the tendon involved, the way it’s being loaded, and the tissue response beneath the surface can differ quite a bit. Because of that, these problems are often easier to brush aside than they should be, especially when the discomfort seems mild, settles for a while, or only shows up after certain activities.
At the same time, tendonitis is often the first term most come across, even though the issue might be more nuanced than that label suggests. They might then encounter terms such as tendinitis, tendinosis, tenosynovitis, or tendinopathy when searching online, and start to wonder whether these all mean the same thing. Medically, they are related, but not identical. Tendinitis, also commonly spelled tendonitis, refers to inflammation of the tendon itself, while tenosynovitis affects the sheath around a tendon. Rather than getting too caught up in the wording at the outset, it’s best to first look at how these problems tend to present. After all, the location of the discomfort, the activity that causes it, and the way symptoms behave over time can offer clearer clues about which tendon might be involved.
Why Lower Limb Tendon Pain Can Be Difficult to Identify
What makes lower limb tendon problems harder to pin down is that they don’t all present in one clear or predictable way. While the discomfort is often linked to movement or load, the trigger can vary depending on the structure involved. In some cases, symptoms are more noticeable when climbing stairs or squatting. In others, they are brought on by walking, push off, side to side movement, or pressure over the top of the foot. So before narrowing things down, it often helps to look more closely at where the pain is felt, what tends to bring it on, and how it changes over time.
Patellar Tendonitis
Patellar tendonitis affects the tendon just below the kneecap and is often linked to repeated strain through jumping, landing, squatting, or stair climbing. Because it’s commonly seen in sports that place higher load through the knee, it’s also known as jumper’s knee.
- Pain is usually felt just below the kneecap.
- Symptoms often become more noticeable with jumping, squatting, stairs, or push off.
- Discomfort might begin during sport or after activity, then become more persistent over time.
- The tendon can feel tender when pressed.
- Repeated loading through the knee is a common contributing factor.
Posterior Tibial Tendonitis
Posterior tibial tendonitis affects a key tendon along the inner side of the ankle that helps support the arch and stabilise the foot during walking. When this tendon becomes irritated, the pain is often felt around the inside of the ankle or arch, especially after longer periods on the feet.
- Pain is usually felt along the inner side of the ankle or into the arch.
- Symptoms might become more noticeable after walking, exercise, or push off.
- The area can feel sore or swollen as the irritation builds.
- In some cases, standing on tiptoe or balancing on the affected foot becomes harder.
- Ongoing strain through the tendon can gradually affect arch support over time.

Peroneal Tendonitis
Peroneal tendonitis affects the tendons along the outer side of the ankle and foot, where they help steady the foot during walking and movement. When these tendons become irritated, the pain is usually felt around the outer ankle, especially with repeated activity or loading.
- Pain is usually felt around the outer ankle or along the outer side of the foot.
- Symptoms often become more noticeable with walking, running, or repeated loading.
- The area might feel tender, and in some cases slightly swollen.
- Uneven ground or side to side movement can make the ankle feel less comfortable.
- Overuse, repeated strain, or an ankle sprain can all contribute to the problem.
Extensor Tendonitis
Extensor tendonitis affects the tendons that run across the top of the foot and help lift the toes during walking. When these tendons become irritated, the pain is usually felt over the top of the foot, especially with movement, longer periods on the feet, or pressure from footwear.
- Pain is usually felt across the top of the foot.
- Symptoms might become more noticeable with walking, running, or time spent on the feet.
- The area can feel tender, and in some cases mildly swollen.
- Pressure from shoes or tightly tied laces might make the discomfort worse.
- Repeated strain, activity changes, or footwear pressure can all contribute to the problem.
Achilles Tendonitis
Achilles tendonitis affects the tendon at the back of the ankle that helps with push off during walking, stair climbing, and running. When this tendon becomes irritated, the pain is usually felt at the back of the heel or just above it, especially after activity or when the tendon has stiffened after rest.
- Pain is usually felt at the back of the heel or ankle.
- Symptoms might become more noticeable with walking, running, stairs, or push off.
- The tendon can feel stiff, especially after rest or first thing in the morning.
- In some cases, the area might feel tender, slightly swollen, or thickened.
- Repeated strain, calf tightness, or a sudden increase in activity can all contribute to the problem.
Have Your Lower Limb’s Pain Assessed at Straits Podiatry
When pain in the knee, ankle, or foot keeps returning, starts showing up more easily, or begins to affect walking, exercise, or day to day movement, it’s usually a sign that the problem needs a closer look by a podiatrist. At first, it might still seem manageable. Even so, this can change when the same strain continues building in the background, especially if the pain keeps following a similar pattern without properly settling.
Here at Straits Podiatry, our aim isn’t simply to put a label on the pain and assign a generic treatment to it. Instead, it’s to assess the problem thoroughly, understand how the area is responding to load, and identify what might be contributing to the strain in the first place. This includes looking at where the discomfort is felt, what tends to bring it on, how it behaves over time, and how these findings fit with your daily activity needs. Having done so, the next step is to put together a care plan that’s better matched to the structure involved, the demands placed on the area, and what you need in order to move more comfortably again. Book an appointment today for a professional assessment, especially if your lower limb tendon pain is persistent, recurring, or becoming harder to ignore.
