Filter by:This study is a prospective randomized controlled clinical study. After the Achilles tendon rupture repaired by our suture technique, patients were randomly divided into 4 groups, and the brace fixation time was 0, 2, 4 and 6 weeks, respectively, to study the difference in efficacy between the groups.
The purpose of this study is to examine the effect of utilizing blood flow restriction (BFR) therapy in the rehabilitation of Achilles tendon rupture (ATR). Muscle atrophy occurs following Achilles tendon rupture, whether managed non operatively or operatively, which has implications on patient outcomes. The goal of physical therapy in the perioperative period is to regain and ultimately return to activity. BFR has been proposed to reduce atrophy and maintain strength, which would theoretically mitigate the deconditioning effects of an injury on surrounding musculature. BFR is proposed to work by restricting arterial inflow leading to an oxygen depleted environment and the ability to induce muscle adaption at lower maximum repetition via reactive hyperemia and induction of growth cytokines, thus leading to muscle hypertrophy. The goal of this investigation is to determine if using BFR as an adjunct in physical therapy following ATR would reduce muscular atrophy and lead to increased and expedited strength gains. Additionally, the investigators would like to determine if BFR accelerates the rehabilitation process and allows patients to perform standard rehabilitative functional tests and return to play sooner. Furthermore, the investigators will investigate patient reported outcomes metrics. The investigators hypothesize that the BFR group will have significantly greater strength gains at all time points in both non operatively and operatively treated ATR. Previous studies have shown that BFR has potential in increasing Achilles tendon stiffness, tendon cross-sectional area, muscle strength and muscle hypertrophy. However, there is a lack of evidence regarding the use of BFR in both the pre and postoperative period specifically relating to ATR. The investigators believe that the use of BFR in the perioperative period surrounding an Achilles tendon rupture and ATR has the potential to significantly decreased muscle atrophy, improve patient satisfaction and lead to earlier return to sport.
This retrospective study identified 12 patients with Achilles sleeve avulsion from November 2013 to March 2016, aiming to explore a new transosseous suture technique for the repair of Achilles sleeve avulsion and observe the short-term curative effect.
Patients with acute achilles tendon rupture will go through an acute ultrasound. Based on the distance between the ends of the tendon the investigators will decide if the patient is going to be treated with or without surgery.
This is a retrospective chart review to determine the etiologies contributing to prolonged PACU discharge at a major Orthopedic Ambulatory Center
The purpose of the study is to investigate if delayed loading following surgical treated Achilles tendon rupture influence the clinical outcome and muscle and tendon structure after one year. The investigators hypothesize that delaying the gradual introduction of loading in the initial 26 weeks may reduce the heel-rise deficit (primary outcome) and thus improve the clinical outcome one year after surgery (primary endpoint).
The aim of this study is to investigate the feasibility of an early progressive exercise program for patients with Achilles tendon rupture treated non-surgically. The outcomes will concern the patient's acceptability of the intervention, adherence to the intervention and safety of the healing tendon.
The purpose of this study is to evaluate the surgically repaired tendon of a ruptured achilles tendon. We will investigate fixation slippage and tendon creep and correlate how these post-repair findings can contribute to outcomes of tendon repairs.
The etiology and pathogenesis of acute Achilles tendon ruptures are complex and not fully understood. It is well known that they are associated with pre-existing pathological alterations, similar to the changes observed in tendinopathy. The present study investigates if bacteria and collagen metabolism play a role in the etiology of acute Achilles tendon rupture. During surgery, 20 patients will have taken two biopsies from the ruptured part of the tendon and two biopsies from the healthy tissue of the same tendon 2-4 cm proximal to the rupture, as a control.
Early rehabilitation protocols have been studied in Achilles tendon (AT) rupture patients, but deficits in tendon biomechanical properties have been observed several years after the injury. AT rupture patients are unable to return to their previous levels of physical activity. They present deleterious adaptations in the plantar flexor muscles that lead to functional deficits, and deficits in the tendon's structural and mechanical properties. Eccentric contractions have been suggested to recover these muscle properties. This contraction is known to produce higher force compared to isometric and concentric contractions, and increases tendon stiffness. However, there is a lack of studies showing the effects of the eccentric training in AT rupture rehabilitation. We want to know if an isokinetic eccentric training program will determine the desired adaptations on triceps surae muscle-tendon unit's properties in patients subjected to the AT surgical repair. More specifically, the aim of this study is verifying the effects of a 12-week eccentric training program on triceps surae muscle-tendon unit's properties in subjects that were subjected to the AT surgical repair. 30 subjects will be randomized in two groups: (1) isokinetic eccentric training; and (2) traditional eccentric training control group. All participants will be submitted to a four-week control period, followed by a 12-week period of training for the plantar flexor muscles. Neuromuscular system properties, AT biomechanical properties and functional tests will be evaluated. Participants will be evaluated in four moments: at baseline; after 4, 8 and 12 weeks of rehabilitation. Tendon mechanical (stiffness, stress, strain), material (Young's modulus) and morphological (cross-sectional area and tendon length) properties; muscle architecture (thickness, pennation angle and fascicle length); and functional tests (heel rise resistance and height) will be analyzed between groups and periods. Effects and interactions will be analyzed with ANOVA two-way. Clinical effects will be analyzed using effect size and magnitude-based inferences.
