“…19,20 Finally, the results of the current study also suggest that patients with stage I PTTD exhibit similar arch structure and ankle invertor strength as compared to healthy controls and that these variables may not be associated with early identification of the condition. 5,34 In contrast, individuals in the more severe stages of the PTTD progression generally exhibit marked differences in arch height, strength, and gait kinematics. 20,24 Several limitations are acknowledged.…”

“…Moreover, the lack of differences in MLA between groups for the present study and a reported 8° change in MLA for stage II PTTD 32 suggest that stage I PTTD may not involve midfoot or forefoot changes in walking kinematics, whereas these factors may be apparent in stage II and beyond. 5,7,34 Thus, PTTD progression may be best understood by rearfoot kinematic measures during stage I, whereas altered midfoot and forefoot kinematics may play a role in stage II and beyond. 19,20 Finally, the results of the current study also suggest that patients with stage I PTTD exhibit similar arch structure and ankle invertor strength as compared to healthy controls and that these variables may not be associated with early identification of the condition.…”

Posterior tibial tendon dysfunction (PTTD) is a progressive and debilitating condition that is estimated to affect nearly 5 million people in the United States. 7 In the early stages (stage I) of the condition, PTTD is a common running-related injury. 31While the aetiology of PTTD has not been established, it is considered multifactorial in nature and has generally been related to progressive alterations in arch structure, muscular strength, and gait biomechanics. T T BACKGROUND:PTTD is a progressive condition, so early recognition and treatment are essential to help delay or reverse the progression. However, no previous studies have investigated stage I PTTD, and no single study has measured static anatomical structure, muscle strength, and gait mechanics in this population. T T METHODS: Twelve individuals with stage I PTTDand 12 healthy, age-and gender-matched control subjects, who were engaged in running-related activities, participated in this study. Measurements of arch height index, maximum voluntary ankle invertor muscle strength, and 3-dimensional rearfoot and medial longitudinal arch kinematics during walking were obtained. T T RESULTS:The runners with PTTD demonstrated significantly lower seated arch height index (P = .02) and greater (P = .03) and prolonged (P = .05) peak rearfoot eversion angle during gait, compared to the healthy runners. No differences were found in standing arch height index values (P = .28), arch rigidity index (P = .06), ankle invertor strength (P = .49), or peak medial longitudinal arch values (P = .49) between groups. T T CONCLUSION:The increased foot pronation is hypothesized to place greater strain on the posterior tibialis muscle, which may partially explain the progressive nature of this condition.

“…The PTT is the tendon of the ankle most usually damaged in middle-aged and elderly women 16---18 mainly in a spectrum of injuries ranging from peritendonitis to tendinosis, then tio partial focal tear and eventually leading to complete tear 17,19,20 . The degeneration and tear of the PTT usually occurs in the tarsal tunnel or the perimalleolar region due to the relative hypovascularization of this area 21---23 and pressure exerted on the tendon.…”

“…TPT dysfunction is under-recognised and early stages of the disease are rarely diagnosed in the ED 4 5. Patients may complain of pain and swelling around the medial ankle following forced eversion, difficulty in mobilising and tenderness along the course of the tendon.…”
