Posterior Tibial Tendon Dysfunction (PTTD) Therapy
What is Posterior Tibial Tendon Dysfunction (PTTD)?
Posterior Tibial Tendon Dysfunction (PTTD) is a condition that is characterised by the weakening or tearing of the posterior tibial tendon, which runs along the inside of the ankle and foot.
When this tendon becomes damaged or inflamed, it can lead to symptoms like pain, swelling, and a progressive flattening of the foot. PTTD is often referred to as adult-acquired flatfoot because it typically develops in adults and leads to the gradual loss of the arch.
Understanding the nature of PTTD, including its symptoms, causes, diagnosis, and treatment options, is essential for effective management. At UFIT Podiatry, a specialised approach is adopted to provide relief and promote recovery for individuals suffering from PTTD.
What is Posterior Tibial Tendon Dysfunction (PTTD)?
Posterior Tibial Tendon Dysfunction (PTTD) is a condition that affects the posterior tibial tendon, which plays a crucial role in supporting the arch of the foot and maintaining proper foot mechanics. When this tendon becomes damaged or inflamed, it can lead to pain, swelling, and a progressive flattening of the foot. Understanding the nature of PTTD, including its symptoms, causes, diagnosis, and treatment options, is essential for effective management. At UFIT Podiatry, a specialized approach is adopted to provide relief and promote recovery for individuals suffering from PTTD.
PTTD is a progressive condition characterized by the weakening or tearing of the posterior tibial tendon, which runs along the inside of the ankle and foot. This tendon is responsible for supporting the arch and stabilizing the foot during movement. When the tendon becomes dysfunctional, it can lead to a collapse of the arch, resulting in flatfoot deformity. PTTD is often referred to as adult-acquired flatfoot because it typically develops in adults and leads to the gradual loss of the arch.
Symptoms of Posterior Tibial Tendon Dysfunction (PTTD)
The symptoms of PTTD can vary depending on the stage of the condition but generally include:Pain and Swelling
Pain along the inside of the ankle and foot, which may be accompanied by swelling. The pain often worsens with activity.
Flatfoot Deformity
A visible flattening of the arch, leading to an outward rolling of the ankle and foot.
Weakened Foot Function
Difficulty in standing on tiptoe or performing activities that involve pushing off with the affected foot.
Limited Mobility
Reduced range of motion in the foot and ankle, making walking or other activities painful and challenging.
Tenderness in the
Inner Ankle or Arch
Tenderness along the course of the posterior tibial tendon, from the inside of the ankle to the middle of the arch.
Knee & Back Pain
Feeling pain in any part of your and/or have back pain after a long day of activity


Causes of Posterior Tibial Tendon Dysfunction (PTTD)
Stages of Posterior Tibial Tendon Dysfunction (PTTD)
Understanding its stages helps in early diagnosis and appropriate intervention at podiatry clinics.
Stage 1: Early Inflammation & Pain
In this initial stage, the posterior tibial tendon is inflamed and painful, typically along the inside of the ankle and foot. There may be mild swelling, but the foot arch remains largely intact and flexible. Walking may be painful.
Stage 2: Tendon Damage & Arch Collapse
As the condition progresses, the posterior tibial tendon begins to lengthen and degenerate, losing its ability to support the arch effectively. Patients often experience increased pain, weakness, and difficulty with activities like walking or running. At this stage, you may not be able to stand on your toes on one leg.
Stage 3: Rigid Flatfoot Deformity
At this advanced stage, the foot deformity from Posterior Tibial Tendon Dysfunction becomes more significant and rigid. Arthritis may begin to develop in the joints of the hindfoot due to the chronic misalignment and increased stress. Pain symptoms are often more severe and constant, and walking can become significantly impaired.
Stage 4: Ankle Deformity & Arthritis
The most severe stage involves the progressive flatfoot deformity extending to affect the ankle joint. The ankle may start to tilt outwards (valgus deformity), leading to instability and further pain. Significant arthritis develops not only in the foot but also in the ankle joint itself, severely limiting motion and function.

Frequently Asked Questions about Posterior Tibial Tendon Dysfunction (PTTD)
Individuals over the age of 40, especially women, are at higher risk. Other risk factors include obesity, pre-existing flat foot problems, participation in high-impact sports like running or basketball, and certain inflammatory conditions such as rheumatoid arthritis.
Yes, absolutely. Overuse and repetitive stress from activities such as running, jumping, or sports involving sudden changes in direction are common contributors to PTTD. These activities can cause micro-tears and inflammation in the tendon, leading to its progressive weakening.
Physical therapy for PTTD typically focuses on strengthening the posterior tibial muscle and other supporting muscles, improving flexibility, and correcting gait abnormalities. This often includes specific stretching exercises, strengthening exercises for the foot and ankle, and balance training.
In many cases, particularly in the earlier stages, PTTD can be effectively managed and improved with non-surgical approaches. These conservative treatments include custom orthotics in Singapore, braces, physical therapy, activity modification, and anti-inflammatory medication. Surgery is generally considered for more advanced stages or when conservative methods have not provided sufficient relief.
