Introduction
Posterior tibial tendinopathy is a condition characterized by the dysfunction and degeneration of the posterior tibial tendon, which runs along the inner side of the ankle and foot. This vital tendon plays a crucial role in supporting the arch of the foot and controlling foot movement during walking.
Understanding the causes, symptoms, and treatment options for posterior tibial tendinopathy is essential for effectively managing this condition and maintaining optimal foot function. This article aims to explore the causes and treatment of posterior tibial tendinopathy, providing valuable insights into managing this debilitating foot condition.
Anatomy of the Posterior Tibial Tendon
The posterior tibial tendon is a critical structure in the lower leg, playing a pivotal role in maintaining the normal foot arch and stability. This tendon originates from the Tibialis Posterior muscle, positioned deep within the calf. It extends downward, passing behind the medial malleolus—the bony prominence on the inner aspect of the ankle—before attaching to the bones of the midfoot.
The primary function of the posterior tibial tendon is to support the arch of the foot during walking and standing. It also aids in the inversion of the foot, allowing the sole to turn inward. The tendon receives its blood supply from small vessels that are susceptible to injury and inflammation, often leading to conditions like tibial tendonitis.
Understanding this tendon’s anatomy is vital for clinicians in diagnosing issues and crafting treatments such as physical therapy or surgical reconstruction when needed.
Causes of Posterior Tibial Tendinopathy
Posterior Tibial Tendinopathy, commonly associated with tibial tendon dysfunction, is a condition characterized by pain and impaired function in the posterior tibial tendon. Understanding the causes is crucial to proper diagnosis and treatment.
Overuse and Microtrauma
The most frequent cause of posterior tibial tendinopathy results from overuse and repetitive microtrauma to the tendon. This typically occurs in athletes or individuals engaged in high-impact sports or occupations that place continuous stress on the ankle and calf muscles. Microtrauma leads to small tears within the tendon fibers, resulting in inflammation and pain.
Injury
A sudden injury, often seen in high-impact sports like basketball and hockey, such as an ankle sprain or a direct blow to the medial malleolus, can cause significant damage to the posterior tibial tendon. In the realm of hockey, this condition is recognized as one of the most common hockey injuries due to the sport’s physical demands, including rapid direction changes, collisions, and the stress of skating motions. Basketball ankle injuries, in particular, due to the sport’s rapid direction changes, jumping, and landing, heighten the risk of such trauma. This can range from mild inflammation to complete rupture, greatly affecting the tendon’s ability to support the arch.
Age-Related Factors
As we age, the tendons lose some of their elasticity and capacity to handle stress, increasing the risk of tendinopathy. The posterior tibial tendon is no exception, and deterioration can progressively lead to tibial tendon insufficiency, particularly in adults over 40.
Flat Feet (Pes Planus)
An individual with flat feet lacks natural arch support, placing extra strain on the posterior tibial tendon. This can exacerbate or even cause tibial tendon dysfunction over time, leading to the development of adult-acquired flatfoot deformity.
Hypertension and Diabetes
Medical conditions such as hypertension and diabetes can affect the blood supply to the soft tissues, including tendons. A compromised blood supply can delay healing or contribute to the degeneration of the tendon fibers, increasing the likelihood of tendinopathy.
Obesity
Excessive body weight puts additional strain on the tendons and can lead to overstretching and weakening of the posterior tibial tendon, increasing the risk for tendinopathy.
Inflammatory Diseases
Conditions that cause systemic inflammation, such as rheumatoid arthritis, can affect the posterior tibial tendon, leading to pain, swelling, and a weakened tendon.
Improper Footwear
Shoes that lack proper support can contribute to the abnormal positioning of the foot and excess stress on the posterior tibial tendon, potentially leading to tendinopathy.
Genetic Factors
There may be hereditary aspects that predispose individuals to weaker tendons or issues like flat feet, which in turn can increase the risk of developing posterior tibial tendinopathy.
Signs and Symptoms of the Posterior Tibial Tendinopathy
Pain and Swelling
- Discomfort inside the ankle, near the medial malleolus.
- Swelling may be present along the course of the tendon.
Change in Foot Shape
- The development of adult-acquired flatfoot deformity.
- Collapse of the foot’s arch, leading to a flatter foot.
Difficulty Walking
- Challenges with activities that involve pushing off the foot.
- A tendency to walk on the inner side of the foot.
Inability to Perform the Heel-Rise Test
- Difficulty or inability to stand on tiptoes on the affected foot.
- Known as the single heel raise, an indication of tendon dysfunction.
Tenderness
- Sensitivity to touch along the posterior tibial tendon route.
Decreased Flexibility
- Limited range of motion in the ankle joint.
- Stiffness that impedes normal foot movement.
Diagnosis of Posterior Tibial Tendinopathy
Diagnosis of Posterior Tibial Tendonopathy typically begins with a thorough physical examination followed by imaging tests.
Physical Examination
During a physical assessment, a healthcare provider will evaluate for tenderness along the Tibialis Posterior tendon, particularly in the area behind the medial malleolus. The single heel raise test is crucial for assessing the function of this tendon, where the patient attempts to stand on the toes of one foot. Difficulty or inability to perform this task can be indicative of tibial tendon dysfunction.
Imaging Test
Imaging tests such as Magnetic Resonance Imaging (MRI) play a vital role. MRIs allow physicians to visualize the inflamed tissues and the condition of the tendon and surrounding soft tissues. Other imaging tests may include ultrasound or X-rays to assess for flat feet or changes to the alignment of the ankle bones.
In a recent study, it was discovered that 67% of participants showed signs of tendinopathy in their tibialis posterior tendons, even though they did not experience any pain in the medial foot/ankle region. Additionally, almost half (48.1%) of the tibialis posterior tendons evaluated through ultrasound examination exhibited such changes. This highlights the importance of imaging tests in determining the prevalence of tendinopathy in individuals with tibialis posterior tendons, suggesting that it may be more common than previously thought.
Treatment Options for Posterior Tibial Tendinopathy
Posterior tibial tendonitis treatment option starts conservatively and may progress to surgical intervention depending on severity.
Physical Therapy: Strengthens calf muscles and the tibial tendon, improving foot mechanics.
Rest and Immobilization: A walking boot or cast helps decrease stress on the tendon, allowing it to heal.
Medications: Anti-inflammatory drugs can reduce pain and swelling.
Activity Modification: Avoiding activities that exacerbate symptoms is recommended, alongside incorporating specific posterior tibial tendinopathy exercises. These targeted exercises are designed to strengthen and stretch the affected tendon, promoting healing and reducing the risk of further injury.
Footwear: Shoe inserts or custom orthotics can provide support for a flat foot, relieving tendon strain.
Bracing: A posterior tibial tendonitis brace may help stabilize the ankle joint and limit tendon movement during recovery.
Surgical Intervention: Considered In severe cases or when nonsurgical treatments fail.
- Posterior tibialis tendon surgery: Repairs the damaged tendon.
- Surgical reconstruction: Addresses flat foot deformity or changes in the alignment of the ankle bones.
Prevention Of Posterior Tibial Tendon
Foot Care & Hygiene
Ensuring good foot care and maintaining proper hygiene are essential in preventing posterior tibial tendon dysfunction. This involves regular cleaning, drying of feet to prevent infections, and checking for any signs of inflammation or pain.
