Understanding Posterior Tibial Tendonitis: Briefly Explained
Posterior tibial tendonitis, often shortened to PTT, is one of the common foot complaints seen within the NHS. This particular condition occurs when inflammation and swelling affect the posterior tibial tendon, a key tendon located on the inside of your leg and ankle. This tendon has an important role—it maintains arch support and helps stabilise your foot and ankle during movement.
If you’re experiencing posterior tibial tendonitis, you’ll typically notice discomfort or swelling around the inside ankle area, particularly when walking, standing on tiptoes or running up an incline. Left untreated, symptoms can gradually progress to potentially serious problems, affecting your overall mobility.
But there’s good news: posterior tibial tendonitis generally responds well to specially targeted exercises and self-care measures. NHS practitioners are well-versed in gently guiding patients through exercises aiming not only to relieve symptoms but also to prevent recurrence.
The Importance of Engaging in Correct Exercises
Choosing and performing tailored exercises from reliable sources like the NHS is fundamental in managing posterior tibial tendonitis effectively. Exercise therapy aims to relieve pain, strengthen supportive muscles, promote healing of the tendon, and restore natural foot function gradually.
Always follow proven advice from reputable sources—and ideally consult an NHS health professional, such as a physiotherapy specialist, prior to initiating any rehabilitation programme. This ensures your exercise choices are appropriate for your unique condition stage and severity and prevents unnecessary aggravation of your injury.
NHS-Recommended Exercises for Posterior Tibial Tendonitis
Below we’ve outlined a range of exercises commonly recommended by NHS physiotherapists to help combat posterior tibial tendonitis. Whether you’re experiencing mild aching or more significant symptoms, incorporating these into a regular routine can lead to steady improvement.
Gentle Calf Stretch (Gastrocnemius Stretch)
Calf stretches are crucial in the early rehabilitation phase, allowing calf muscle tension to ease and helping relieve stress around the posterior tibial tendon.
To perform this exercise:
- Stand facing a wall, hands placed comfortably against it.
- Step one leg back, ensuring the heel stays flat on the ground.
- Bend your front knee forward slowly, keeping your back leg straight.
- You should feel a gentle stretch along the back calf. Hold for 20–30 seconds.
- Repeat 3–5 times each leg, ideally twice daily.
Soleus Muscle Stretch
Targeting deeper calf musculature like the soleus muscle helps reduce additional tension placed upon the posterior tibial tendon.
Here’s the ideal way to perform this stretch:
- Stand facing a wall, place palms against it for stability.
- Step slightly closer to the wall compared to your first calf stretch.
- With feet pointing straight forward, gently bend both knees, but primarily emphasise bending your back knee.
- You’ll feel a lower stretch around your Achilles area and deep within your calf.
- Hold for around 20–30 seconds. Repeat 3–5 times, twice daily.
Towel Scrunches to Improve Foot Strength
Strengthening intrinsic muscles within your foot improves support to the posterior tibial tendon and enhances arch strength. For towel scrunches:
- Sit comfortably on a chair with feet flat on a towel placed upon the floor.
- Use your toes to grip and pull the towel towards you.
- Repeat these scrunching movements for around 30 seconds at a time, rest, then repeat for around 3–4 sets.
Arch-Lifting Foot Exercise (Foot Doming)
Strengthening your arch can immensely benefit posterior tibial tendon function. Foot doming exercise is effective in activating and reinforcing intrinsic arch muscles:
- Sit comfortably on a chair with feet shoulder-width apart.
- Imagine creating a slight dome shape with your foot by gently lifting your arch while keeping toes and heel firmly grounded.
- Hold this domed shape for a count of 5–10 seconds, then relax.
- Perform sets of 10–15 repetitions, ideally twice daily.
Resistance Band Strengthening for Tibialis Posterior
Once symptoms are somewhat controlled, resistance band exercises beneficially challenge tendon strength and endurance.
Here’s a common variation recommended by NHS therapists:
- Sit on the floor or chair, wrap a resistance band securely around the ball of your foot, holding the other end firmly in your hand.
- Slowly rotate your ankle inwardly against the band’s resistance, then slowly release back to a neutral position.
- Repeat slowly and intentionally for around 10–15 repetitions and complete 2–3 sets. Build repetitions and resistance levels gradually over weeks.
Lifestyle and General NHS Advice to Maximise Recovery
Exercises alone are highly beneficial, but combining them with broader lifestyle adjustments will significantly enhance your recovery progress:
- Wear supportive footwear with adequate arch support during activities.
- Gradually reintroduce normal exercise routines, avoiding sudden increases in training intensity or frequency.
- Use over-the-counter anti-inflammatory medications or ice application (wrapped in a towel) to help reduce inflammation and ease discomfort—as recommended by your NHS healthcare provider.
- Consider physiotherapist advice on customised orthotics if required to enhance foot biomechanics.
When to Seek Further Medical Advice from Your NHS Healthcare Provider
Most cases of posterior tibial tendonitis manage well with these conservative NHS recommendations. Nevertheless, being aware of scenarios requiring professional assistance is crucial.
Please contact an NHS healthcare professional promptly if:
- The pain noticeably worsens or persists despite consistent exercise efforts.
- You notice significant swelling, severe discomfort or difficulty bearing weight that affects daily routines.
- You identify notable deformities in the shape of your foot arch developing or worsening.
Failing to get timely intervention could potentially lead to chronic ankle instability or deformity, making early intervention critical.
The Road to Recovery: Patience and Progression with NHS-Guided Exercises
Rehabilitation of posterior tibial tendonitis largely depends on patience, consistency, and appropriate exercise technique performed regularly. NHS physiotherapists frequently emphasise gradual progression and moderation over rapid approaches that might exacerbate symptoms.
It’s entirely normal that improvements happen gradually, typically spanning weeks to months, depending on symptom severity, individual factors, and consistency of exercise.
Keep motivated, stay confident, and—with NHS-approved exercise guidance—you’ll find yourself steadily regaining comfortable and active movement, returning safely to the activities you enjoy.
