Posterior Tibial Tendon Dysfunction

Understanding Posterior Tibial Tendon Dysfunction: Causes, Symptoms, and Treatments

Tibial tendon dysfunction, also known as PTTD, is a prominent contributor to pain in the foot and can lead to difficulty with movement. This guide provides an insightful understanding of what posterior tibial tendon dysfunction entails, its causes, identifiable symptoms, and practical approaches for rehabilitation. Join us as we explore effective treatment options and techniques to preserve the health and function of your feet amidst challenges posed by PTTD.

Key Takeaways

  • The posterior tibial tendon is crucial for foot stability. It enables efficient gait, but it’s prone to disorders like PTTD, which can result in flatfoot conditions and requires potential treatments ranging from conservative care to surgery.
  • Early symptoms of PTTD include tenderness and swelling along the tendon, progressive pain with activity, and changes in foot shape. At the same time, diagnosis is aided through physical examinations and imaging techniques like X-rays, ultrasound, and MRI.
  • Conservative treatments for PTTD, such as orthotics, bracing, and physical therapy, focus on pain relief and slowing the progression of the deformity, whereas surgery might be necessary to correct severe or unresponsive cases.

Exploring the Role of the Posterior Tibial Tendon in Foot Health

The posterior tibial tendon plays a crucial role in maintaining the stability of the medial longitudinal arch and is essential for proper foot support from the inside. It stems from where it originates at the back and side of the upper part of the shinbone, lying deep within that area’s rear compartment, functioning in unison with the deltoid ligament to achieve its purposes. Its primary responsibilities are facilitating plantarflexion and inversion of our ankles, which are fundamental actions required for standing, walking, or running effectively.

This critical tendon assists us in sustaining an upright posture and transitioning smoothly through each phase of our gait cycle, particularly moving from heel strike towards toe-off. This posterior tibial tendon remains vulnerable to injuries or progressive wear and tear despite its strength and importance. Such deterioration could lead to conditions identified as either posterior tibial tendonitis or, more broadly, encompassing dysfunctions like PTTD (posterior tibial tendon dysfunction) and related insufficiency issues. To combat these problems when they occur – ensuring relief from symptoms while providing necessary stabilisation – sometimes wearing a specialised supportive device known as a walking boot may be advised.

Unveiling the Mechanism Behind Posterior Tibial Tendon Dysfunction (PTTD)

Should the posterior tibial tendon fail to perform effectively, its critical role in supporting the medial longitudinal arch is compromised, often leading to a condition known as flat foot. This failure typically stems from tendon degeneration associated with reduced blood supply and increased stress on the tendon, particularly at its sharp turn near the medial malleolus.

Degenerative changes in the Achilles tendon can result in various issues, such as:

  • development of heel valgus alignment
  • alteration to a lateral orientation of the tendon axis
  • occurrence of either acute rupture or degeneration due to repeated microtrauma
  • replacement of normal tendon tissue by fibrous material
  • disintegration of the medial longitudinal arch’s structural integrity
  • progression towards an advanced stage flatfoot deformity

In some instances, it might also necessitate Achilles tendon lengthening procedures.

Identifying the Symptoms: Recognising PTTD Early On

Patients with PTTD may initially notice subtle signs such as swelling and tenderness around the tendon, particularly in the region behind and beneath the medial malleolus, and inflammation and discomfort surrounding the inner part of the ankle joint. These symptoms typically intensify during physical activities, resulting in challenges when attempting tasks like standing on tiptoe or manoeuvring across uneven terrain, which can aggravate any existing limp.

As PTTD advances, noticeable deformities emerge due to changes in foot structure—specifically, a deterioration of the medial longitudinal arch that leads to flatfootedness and a heel that shifts into a valgus alignment. A classic indicator of advancing PTTD is the ‘too many toes’ sign. This occurs when an observer can see more than one or two toes from outside (the lateral view), suggesting that there has been a significant collapse of the medial longitudinal arch.

Risk Factors and Causes: Understanding Who is at Risk for PTTD

Numerous risk factors can increase the likelihood of developing posterior tibial tendon dysfunction (PTTD). These risk enhancers include obesity, elevated blood pressure, diabetes, prior injuries to the ankle region, steroid exposure, and inflammatory conditions such as seronegative arthropathies. Such factors elevate the susceptibility to PTTD.

The risk for PTTD is notably higher in women and individuals over 40 years old. This condition has a strong correlation with adult-acquired flatfoot deformity. The typical individual frequently diagnosed with adult-acquired flatfoot tends to be an overweight female around her sixties.

Henceforth it’s clear that specific demographics and health issues play a significant role in predisposing someone towards acquiring flatfoot deformity. Understanding these risks may aid in both prevention and early detection strategies for those potentially affected by adult-acquired flatfoot.

Diagnosing PTTD: From Physical Examination to Advanced Imaging

Assessing PTTD requires a combination of advanced imaging methods alongside physical examination. The single-limb heel-rise test, performed during the physical exam, indicates PTTD as it tests for weakness or difficulty when performing toe rises – a sign of tendon dysfunction. Physical symptoms may include the heel taking on a valgus position and a collapse in the medial longitudinal arch.

Advanced imaging plays an essential role in diagnosing PTTD. Structural changes and progression related to PTTD can be identified through weight-bearing X-rays that capture alterations within the foot’s architecture. Ultrasound provides an efficient and cost-effective way to evaluate tendon size, degeneration, and surrounding fluid accumulation.

Magnetic resonance imaging (MRI) is crucial for identifying early signs of tendon alterations and joint degeneration associated with PTTD, which are pivotal aspects influencing both treatment approaches and considerations for surgery.

Conservative Care Strategies: NNonsurgicalTreatments for PTTD

When detected early, Posterior Tibial Tendon DysfuNonsurgicalD) can be successfully treated using conservative methods that don’t involve surgery. The nonsurgical approaches recommended for managing PTTD consist of the following:

  • Utilising supportive braces
  • Enonsurgicalthotic devices
  • Modifying physical activities
  • Taking nonsteroidal anti-inflammatory drugs (NSAIDs)
  • Immobilising the affected area
  • Engaging in physical therapy

The primary goals of these treatment options are to alleviate discomfort, restore standard functionality, and decelerate or stop deformity from developing.

The Role of Orthopedic Devices

The treatment of posterior tibial tendon dysfunction (PTTD) often involves the deployment of specialised orthopaedic aids. Braces designed specifically for PTTD serve as a surrogate ligament, offering substantial support to the tibial tendon and diminishing associated discomforts. Initiating brace usage promptly can help rectify gait irregularities and halt the progression of the affliction. These braces are frequently adjustable, allowing tailored modifications to provide optimal tension that benefits the tibial tendon.

Similarly lauded for their effectiveness in treating PTTD are custom-fitted orthotic inserts which deliver essential arch support to ease symptoms related to this condition. Ankle-foot orthoses (AFOs), devices purposed for ankle stabilisation and foot reinforcement, may be prescribed in managing PTTD—aiding in symptom management and upkeep of foot anatomy over time.

Physical Therapy and Rehabilitation

Rehabilitation and physical therapy are crucial in managing PTTD, aiming to bolster the weakened muscles, enhance their flexibility, and augment balance and proprioception. Targeted exercises that encourage plantarflexion coupled with inversion efficiently strengthen the Tibialis Posterior muscle—this support for the arch is vital in correcting problems tied to muscular weakness. Utilising tools such as therabands and weights can be beneficial when performing resistance-focused ankle movements designed to stabilise the foot experiencing PTTD.

Treatment extends beyond just focusing on the foot itself. Strengthening leg muscles around both hips and knees is essential in maintaining correct limb alignment during activities supporting those supporting PTTD. Engaging regularly in a range of motion routines like runner’s stretch or towel ankle stretches alongside calf stretching proves indispensable for preserving suppleness within one’s feet and ankles, thus averting rigidity. Honing balance skills through practices like standing on a single leg or employing balance boards takes some pressure off an impaired posterior tibial tendon—a significant aspect of recovery efforts.

When Surgery Becomes Necessary: Surgical Treatment Options

In instances where nonsurgical methods fail to produce results and before the foot deformity solidifies into a nonsurgical state, surgery for Posterior Tibial Tendon Dysfunction (PTTD) may be required. Surgical options for PTTD vary from bone realignment procedures known as osteotomies to arthritis in situations of advanced arthritis, along with the implantation of apparatus such as titanium supports to address extreme pronation.

Reconstructing the Medial Arch: Flatfoot Correction Procedures

A foot and ankle surgeon aims to restore the medial arch of the foot, correct its shape, alleviate discomfort, and improve function through flatfoot correction surgeries. The choice of surgical approach depends on various factors, including how severe the tendon and ligament damage is, whether arthritis has set in within any joints involved, and considering patient-specific health conditions.

Occasionally, some techniques may be employed to realign bones without transferring tendons. They primarily concentrate on rectifying alignment issues for reconstructing the arch. In contrast, other procedures might require manipulating bone structure and moving tendons. Ankle surgeons have methods such as Evans’, Kidner’s or Hoke’s, which are adept at correcting deformities and specifically targeting problems with a malfunctioning tibialis posterior tendon or addressing instances of forefoot abduction.

Joint Preservation vs. Joint Fusion

Deciding whether to opt for joint preservation or proceed with joint fusion in addressing PTTD hinges on multiple considerations, such as the extent of the foot deformity, the presence of arthritis and what activities and functional demands are expected by the patient. Joint preservation aims to maintain or improve foot mobility using procedures like Evans Calcaneal Osteotomy and rotational calcaneal osteotomies that correct malalignment while preserving movement within joints.

In contrast, arthritis—commonly known as joint fusion—is adopted not only to align but also to eliminate arthritis from a rigid flatfoot condition. This results in a stable foot that is less mobile. Typically regarded as a last resort when confronting severe arthritis associated with an inflexible flatfoot, fusing major joints can lessen pain and enhance walking ability. Nevertheless, it might prompt additional ankle arthritis over time due to changes in how forces operate through altered foot biomechanics.

Life After PTTD Treatment: Recovery and Long-Term Management

Recovering from PTTD treatment is slow and steady, requiring consistency and determination. Typically, the recovery period for PTTD spans 6 to 8 weeks but may be extended over several months based on how severe the condition is. For those undergoing surgical treatment, full recovery and noticeable reduction in pain can take upwards of half a year.

Gradual resumption of activities after treating PTTD under the supervision of a physical therapist is crucial. It’s also essential to follow all recommended treatments closely to prevent delays or complications during recovery. Long-term management strategies for PTTD may involve shifting towards low-impact exercises and require collaboration among healthcare professionals such as physicians, nurses, and pharmacists for adequate control.

Regular check-ins with medical professionals are critical in monitoring healing progress. Recovery plans post-surgery are explicitly designed—whether they’re aimed at preserving joint integrity or necessitating fusion—to ensure that healing proceeds optimally while restoring foot function.


Recognising the importance of the posterior tibial tendon for foot well-being and movement is vital in addressing PTTD. It’s critical to grasp not only how this condition affects the body but also its symptoms, mechanisms involved, risk factors leading up to it, and diagnostic methods necessary for detection. Early intervention is imperative. Management options range from conservative treatments like orthotic supports and physical therapy aimed at restoring function while alleviating discomfort to surgical procedures if required—all with a focus on enhancing life quality. A consistent dedication towards maintaining foot health can effectively keep PTTD under control throughout one’s lifetime.
