- ItemAchilles Tendon Allograft Preparation Technique for Anterior Cruciate Ligament Reconstruction: A Technical Note(2021) Zamorano, Hector; Yanez-Diaz, Roberto; Vergara, Francisco; Caracciolo, Gaston; Valdes, Sebastian; Yanez-Rojo, Roberto; De la Fuente, CarlosSeveral factors associated with graft preparation for the surgery of the anterior cruciate ligament (ACL) like the wrong thawed, prophylaxis, bone cuts, excessive bone removal as well as positioning problems like a tunnels-graft mismatch, insufficient harvesting of the donor's tendon, size graft limitations (length and diameter), uncontrolled rotation of graft in their longitudinal axis, over or under tensioned graft, fixation mistakes, bone defects, secondary arthrofibrosis or morbidity of the donor site, and others factors importantly affect the outcomes of the ACL surgery. In this sense, the Achilles tendon Allograft is an advantageous technique where many of the previous limitation factors described can be controlled during an appropriate preparation. However, to obtain the maximum potentialities of the graft a detailed knowledge of the preparation is required. Hence, we aimed to describe how to prepare the Achilles tendon Allograft to control the graft's length and diameter, bone removal, and fixation requirements.

- ItemDo the heel-rise test and isometric strength improve after Achilles tendon repair using Dresden technique?(2022) De la Fuente, Carlos; Henriquez, Hugo; Carmont, Michael R.; Huincahue, Javiera; Paredes, Tamara; Tapia, Maria; Araya, Juan Pablo; Diaz, Nicolas; Carpes, Felipe P.Background: Achilles' tendon ruptures result in impaired plantar flexion strength and endurance. It is interesting to know the plantar flexion strength, the number of heel-rise repetitions, and the maximal calf circumference following Achilles' tendon ruptures repair. Methods: Both the injured and non-injured legs of thirty male patients with Achilles' tendon ruptures treated with the percutaneous Dresden technique were compared with the ankle function of 30 healthy participants. Rehabilitation involved partial weight-bearing for three weeks and then increased to full weight-bearing and ankle exercises. Results: The injured legs had weaker plantar flexion strength (1.64 +/- 0.17 Nm/kg) compared with the non-injured legs (1.91 +/- 0.24 Nm/kg; p = 0.002) and the healthy participants' legs (1.93 +/- 0.32 Nm/kg; p < 0.001). The non-injured leg had greater ability in doing heel-rise repetitions (39.4 +/- 6.1 rep.) compared with the injured legs (37.2 +/- 5.7 rep.; p < 0.023) and the healthy participants' legs (31.0 +/- 13.0 rep.; p < 0.001). Conclusions: The injured leg had not recovered full isometric strength but had improved heel-rise repetition. (c) 2021 European Foot and Ankle Society. Published by Elsevier Ltd. All rights reserved.
- ItemEarly Short-Term Recovery of Single-Leg Heel Rise and ATRS After Achilles Tenorrhaphy: Cluster Analysis(2018) De la Fuente, Carlos; Cruz Montecinos, Carlos; De La Fuente, Constanza; Pena y Lillo, Roberto; Chamorro Lange, Claudio Hernán; Henriquez, Hugo
- ItemEccentric and concentric contraction of multifidus lumborum and longissimus muscles during flexion-relaxation test using discrete wavelet transform(2023) Silvestre, Rony; Carlos Letelier, Juan; Perez, Marcelo; Cifre, Manuela; De la Fuente, CarlosPurpose Muscle activation can reflect the stability of the lumbar spine based on the electrical features and kinematics during a dynamic test. However, there is a lack of knowledge of the activation of paravertebral muscles i.e., during the flexion-relaxation test. Hence, we determine the band frequency differences between eccentric (ECC) and concentric (CON) contraction during the flexion-relaxation test in healthy untrained participants without lumbar pain, both multifidus lumborum and longissimus muscles. Methods 40 healthy participants (aged 30.6 +/- 6.9 years) were recruited. Kinematic and surface electromyography were collected to compare the ECC and CON spectral characteristics of both multifidus lumborum and longissimus. The bursts were transformed using a discrete wavelet transform (Daubechies). The band frequencies were compared through mean comparison test with alpha set to 5%. Results Both multifidus lumborum and longissimus muscles had higher intensity in ECC contraction than CON for frequency bands lower than 32 Hz (P < 0.05); meanwhile, there was a higher intensity in CON contraction than ECC for frequency bands higher than 32 or 64 Hz until 256 Hz (P < 0.05). Conclusion For both paravertebral muscles analyzed, discrete wavelet decomposition suggests that during the flexion-relaxation test there is an ECC contraction characterized by low-frequency bands compared with the CON phase characterized by medium- and higher-frequency bands both paravertebral muscles analyzed. The spectral characteristics might be a useful physiological neuromuscular reference to the pathophysiology adaptations of the paravertebral muscle contraction.

- ItemImpact of Visual Biofeedback of Trunk Sway Smoothness on Motor Learning during Unipedal Stance(2020) Cruz-Montecinos, Carlos; Cuesta-Vargas, Antonio; Munoz, Cristian; Flores, Dante; Ellsworth, Joseph; De la Fuente, Carlos; Calatayud, Joaquin; Rivera-Lillo, Gonzalo; Soto-Arellano, Veronica; Tapia, Claudio; Garcia-Masso, XavierThe assessment of trunk sway smoothness using an accelerometer sensor embedded in a smartphone could be a biomarker for tracking motor learning. This study aimed to determine the reliability of trunk sway smoothness and the effect of visual biofeedback of sway smoothness on motor learning in healthy people during unipedal stance training using an iPhone 5 measurement system. In the first experiment, trunk sway smoothness in the reliability group (n = 11) was assessed on two days, separated by one week. In the second, the biofeedback group (n = 12) and no-biofeedback group (n = 12) were compared during 7 days of unipedal stance test training and one more day of retention (without biofeedback). The intraclass correlation coefficient score 0.98 (0.93-0.99) showed that this method has excellent test-retest reliability. Based on the power law of practice, the biofeedback group showed greater improvement during training days (p = 0.003). Two-way mixed analysis of variance indicates a significant difference between groups (p < 0.001) and between days (p < 0.001), as well as significant interaction (p < 0.001). Post hoc analysis shows better performance in the biofeedback group from training days 2 and 7, as well as on the retention day (p < 0.001). Motor learning objectification through visual biofeedback of trunk sway smoothness enhances postural control learning and is useful and reliable for assessing motor learning.
- ItemIntraoperative pivot-shift accelerometry combined with anesthesia improves the measure of rotatory knee instability in anterior cruciate ligament injury(2021) Caracciolo, Gastón; Yáñez, Roberto; Silvestre, Rony; De la Fuente, Carlos; Zamorano, Héctor; Ossio, Alejandra; Strömbäck, Lars; Abusleme, Sebastian; P. Carpes, FelipePurpose: The knee stifness acquired following an Anterior Cruciate Ligament (ACL) injury might afect clinical knee tests, i.e., the pivot-shift maneuver. In contrast, the motor efects of spinal anesthesia could favor the identifcation of rotatory knee defciencies prior to ACL reconstruction. Hence, we hypothesized that the intra-operative pivot-shift maneuver under spinal anesthesia generates more acceleration in the lateral tibial plateau of patients with an injured ACL than without. Methods: Seventy patients with unilateral and acute ACL rupture (62 men and 8 women, IKDC of 55.1±13.8 pts) were assessed using the pivot-shift maneuver before and after receiving spinal anesthesia. A triaxial accelerometer was attached to the skin between Gerdys’ tubercle and the anterior tuberosity to measure the subluxation and reduction phases. Mixed ANOVA and multiple comparisons were performed considering the anesthesia and leg as factors (alpha=5%). Results: We found a higher acceleration in the injured leg measured under anesthesia compared to without anesthesia (5.12±1.56m.s−2 vs. 2.73±1.19m.s−2 , p<0.001), and compared to the non-injured leg (5.12±1.56m.s−2 vs. 3.45±1.35m.s−2 , p<0.001). There was a presence of signifcant interaction between leg and anesthesia conditions (p<0.001). Conclusions: The pivot-shift maneuver performed under anesthesia identifes better rotatory instability than without anesthesia because testing the pivot-shift without anesthesia underestimates the rotatory subluxation of the knee by an increased knee stifness. Thus, testing under anesthesia provides a unique opportunity to determine the rotational instability prior to ACL reconstruction.
