Introduction. Baropodometry is used to measure the load distribution on feet during rest and walking. The aim of this study was to evaluate changes in plantar foot pressures distribution due to period of working and due to stretching exercises of the posterior muscular chain.Methods. In this transversal study, all participants were submitted to baropodometric evaluation at two different times: before and after the working period and before and after stretching the muscles of the posterior chain.Results. We analyzed a total of 54 feet of 27 participants. After the working period, there was an average increase in the forefoot pressure of 0.16 Kgf/cm²and an average decrease in the hindfoot pressure of 0.17 Kgf/cm². After stretching the posterior muscular chain, the average increase in the forefoot pressure was 0.56 Kgf/cm²and the hindfoot average pressure decrease was 0.56 Kgf/cm². These changes were not statistically significant.Discussion. It was reported that the strength of the Achilles tendon generates greater forefoot load transferred from the hindfoot. In our study, no significant variation in the distribution of plantar pressure was observed. It can be inferred that baropodometry was a reliable instrument to determine the plantar pressure, regardless of the tension of the posterior chain muscles.

The aim of this study is to systematically review the literature on clinical outcomes of patients who have undergone autologous matrix-induced chondrogenesis (AMIC) for treatment of osteochondral lesions of the talus (OCL) and compare the studies' outcomes. Pubmed and Embase were searched in January 2020 for articles concerning OCL surgery. Studies were included if they had a minimum 1-year follow-up and the primary measures were functional outcomes. The meta-analysis compared the Visual Analogic Score (VAS), the American Orthopedic Foot and Ankle Score (AOFAS), and the Foot Function Index (FFI) between baseline and follow-up of 1-2years, and 3-5years. A random effects model was used to evaluate outcome changes. The search returned 15 studies, with a total of 492 patients. The VAS improved 4.45 and 4.6 points from baseline to the 1-2year and 3-5yearfollow-up, respectively (p<0.001). AOFAS improved 31.59 and 32.47 points from baseline to the 1-2year and 3-5yearfollow-up, respectively (p<0.001). The FFI showed a significant improvement of 30.93 points from baseline to year 3-5 (p<0.001). A total of 6 patients with revision surgeries have been reported within the follow up period. It was not possible to correlate clinical features like lesion size, surgical approach, and bone marrow stimulation technique to the reported outcome. Surgical treatment of OCL via the AMIC procedure provided significant improvement in the functional outcome and pain scores when compared to the pre-operative values. Improvements were observed up to 5years post-operatively.

Achilles tendon ruptures may lead to proximal retraction of the stump if not treated acutely, increasing the chances of poorer functional outcomes. The flexor halluces longus transfer is a well-established treatment option, usually performed as an open procedure. The aim of this paper is to report the preliminary results and describe the technique of endoscopic flexor halluces longus transfer. Six patients with chronic Achilles tendon injuries or re-ruptures were treated with endoscopic FHL transfer. The Achilles Tendon Rupture Score was used to clinically evaluate the patients. Single leg heel rise ability, functional hallux weakness, complications and procedure length were also checked. On average, we took 56 minutes to perform the surgery. All patients had a major increase in the ATRS score value postoperatively. Single leg heel rise was possible for all patients without limitation. None of the patients noticed functional weakness of the hallux during daily life activity and no wound or soft tissue complications were seen. Endoscopic FLH transfer is a reliable option for patients with high skin risk and soft tissue complications. Other studies are needed to compare this technique with the open procedure, gold standard by now, to ensure its safety and efficacy. 4.

Objective: There are no specific criteria that define the level of amputation in diabetic patients. The objective of this study was to assess the influence of clinical and laboratory parameters in determining the level of amputation and the wound healing time. Methods: One hundred and thirty-nine diabetic patients were retrospectively assessed. They underwent surgical procedures due to infection and/or ischemic necrosis. Type of surgery, antibiotic use, laboratory parameters and length of hospital stay were evaluated in this study. Results: The most common amputation level was transmetatarsal, occurring in 26 patients (28.9%). The wound healing time increased with statistical significance in individuals undergoing debridement, who did not receive preoperative antibiotics and did not undergo vascular intervention. Higher levels of amputation were statistically related to limb ischemia, previous amputation and non-use of preoperative antibiotics. Conclusion: Patients with minor amputations undergo stump revision surgery more often, but the act of always targeting the most distal stump possible decreases energy expenditure while walking, allowing patients to achieve better quality of life. Risk factors for major amputations were ischemia and previous amputations. A protective factor was preoperative antibiotic therapy. Level of Evidence III, Retrospective Study.

Background. The usual initial treatment for insertional Achilles tendinopathy is nonsurgical. Yet there is no standard conservative treatment for Achilles insertional tendinopathy. Shockwave therapy (SWT) has become a reliable option for the management of this illness over the past years. The aim of this study is to report the effectiveness of low-energy SWT associated with an eccentric strengthening protocol in 19 consecutive patients. Methods. This is a prospective study with 19 patients aged between 26 and 72 years diagnosed with insertional Achilles tendinopathy. The protocol consisted of SWT associated with eccentric exercises for 12 weeks. All patients were evaluated on the first day and after 24 weeks (final follow-up) with the Victorian Institute of Sports Assessment–Achilles (VISA-A) score, visual analogue scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) questionnaire, and by algometry. At the last follow-up, patients were also assessed for adherence to the protocol, complications and final outcome (in their perception as success or fail). Results and Conclusion. Fifteen (79%) patients were fully adherent to the Alfredson protocol, and 13 (68%) patients considered the treatment protocol successful. At the last evaluation, patients demanded higher pressure on calcaneus to trigger pain (algometry 1), reported less pain when the algometer was applied with 3 kg (algometry 2), had less global pain (VAS), and had higher AOFAS and VISA-A scores. This study evidences that eccentric loading associated with SWT can dramatically improve patients’ symptoms. We can conclude that eccentric loading associated with SWT is an effective treatment for Achilles insertional tendinopathy. Levels of Evidence: Therapeutic, Level III: Prospective cohort
