Background: Magnetic resonance imaging (MRI) has been used as a diagnostic and prognostic instrument to evaluate the results of conservative treatment for plantar fasciitis. However, there are scarce data available relative to changes in the plantar fascia after operative treatment. The primary objective of this study is to evaluate the imaging changes in patients with recalcitrant plantar fasciitis treated operatively by means of proximal medial gastrocnemius release.
Methods: Thirteen patients with recalcitrant plantar fasciitis were studied with MRI preoperatively and 1 year after operative treatment. Quantitative (plantar fascia thickness) and qualitative variables (hyperintensity in the plantar fascia, insertional calcaneus bone edema, a plantar fascia tear, and the presence of perifascial collections) were assessed by 2 musculoskeletal radiologists. Clinical results were also measured with American Orthopaedic Ankle & Society (AOFAS), visual analog scale (VAS) pain, and 36-Item Short Form Health Survey (SF-36) scales.
Results: The mean plantar fascia thickness was 6.59 mm preoperatively and 6.37 mm postoperatively ( = .972). No statistically significant differences were found in any of the qualitative variables on comparing the pre- and postoperative periods. Patients reported clinical improvements in pain VAS, AOFAS measurement, and the physical subdomains of the SF-36 scale.
Conclusion: Quantitative and qualitative variables assessed for the plantar fascia on MRI did not show any significant change after medial gastrocnemius release despite clear clinical improvement.
Level Of Evidence: Level II, perspective cohort study.

Background: The goal of this study was to examine the effects of spinal cord stimulation (SCS) on muscle activity during walking after lower-limb amputation. Amputation results in a loss of sensory feedback and alterations in gait biomechanics, including co-contractions of antagonist muscles about the knee and ankle, and reduced pelvic obliquity range-of-motion and pelvic drop. SCS can restore sensation in the missing limb, but its effects on muscle activation and gait biomechanics have not been studied in people with lower-limb amputation.

Background: Pregnancy is associated with distinct risks of fascia thickness compared to nulliparous. Therefore, this study aimed to compare plantar fascia thickness between asymptomatic pregnant women and nulliparous, evaluating the relationship with age, body mass index (BMI), arch height index (AHI), gestational age, and number of pregnancies.
Methods: This cross-sectional study was conducted between January and March 2023, and subjects were through a simple random sampling method.

The plantaris tendon may be absent in some individuals, indicating its unclear function. Anatomically, the plantaris tendon originates from the lateral femoral condyle and has a variable course and insertion point at the calcaneal tuberosity. The plantaris tendon may influence conditions such as Achilles tendinopathy, particularly in its midportion, whether by its close relation to the calcaneal tendon or adhesions between both tendons.

Plantar fasciitis (PF), a common cause of heel pain, primarily results from inflammation of the plantar fascia due to excessive strain. Its complex pathophysiology, influenced by various biomechanical factors, has led to the development of diverse surgical techniques. Most of these techniques, when used in isolation, have shown benefits in treating refractory PF.

Objective: This study aims to compare the efficacy of platelet-rich plasma (PRP) and corticosteroids (CS) in treating plantar fasciitis, focusing on pain relief, foot function, and plantar fascia thickness to identify the optimal treatment approach.
Design: A comprehensive search of medical databases was conducted following PRISMA guidelines, utilizing an extensive keyword strategy. Inclusion criteria encompassed prospective RCTs involving adult patients with plantar fasciitis treated with local PRP or CS injections, specifically assessing outcomes such as the Visual Analogue Scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) scores, and plantar fascia thickness.
