“…Gait asymmetries were assessed using a pressure mat system that reliably measures peak pressures and maximum forces in humans 40 and other large animal models. 10,21 Given that the adult Yucatan minipig is of similar size and weight to an adult human, the pressure mat was appropriate to measure the same parameters used in human studies. The porcine model was also well suited for this project given the anatomic and biomechanical similarities between the pig and human.…”

Bridge-Enhanced Anterior Cruciate Ligament Repair Leads to Greater Limb Asymmetry and Less Cartilage Damage Than Untreated ACL Transection or ACL Reconstruction in the Porcine Model

Background: The extent of posttraumatic osteoarthritis (PTOA) in the porcine anterior cruciate ligament (ACL) transection model is dependent on the surgical treatment selected. In a previous study, animals treated with bridge-enhanced ACL repair using a tissue-engineered implant developed less PTOA than those treated with ACL reconstruction (ACLR). Alterations in gait, including asymmetric weightbearing and shorter stance times, have been noted in clinical studies of subjects with osteoarthritis. Hypothesis: Animals receiving a surgical treatment that results in less PTOA (ie, bridge-enhanced ACL repair) would exhibit fewer longitudinal postoperative gait asymmetries over a 1-year period when compared with treatments that result in greater PTOA (ie, ACLR and ACL transection). Study Design: Controlled laboratory study. Methods: Thirty-six Yucatan minipigs underwent ACL transection and were randomized to receive (1) no further treatment, (2) ACLR, or (3) bridge-enhanced ACL repair. Gait analyses were performed preoperatively, and at 4, 12, 26, and 52 weeks postoperatively. Macroscopic cartilage assessments were performed at 52 weeks. Results: Knees treated with bridge-enhanced ACL repair had less macroscopic damage in the medial tibial plateau than those treated with ACLR or ACL transection (adjusted P = .03 for both comparisons). The knees treated with bridge-enhanced ACL repair had greater asymmetry in hindlimb maximum force and impulse loading at 52 weeks than the knees treated with ACL transection (adjusted P < .05 for both comparisons). Although not significant, there was a trend that knees treated with bridge-enhanced ACL repair had greater asymmetry in hindlimb maximum force and impulse loading (adjusted P < .10 for both comparisons) compared with ACLR. Conclusion: Contrary to our hypothesis, the surgical treatment resulting in less macroscopic cartilage damage (ie, bridge-enhanced ACL repair) exhibited greater asymmetry in load-related gait parameters than the other surgical groups. This finding suggests that increased offloading of the surgical knee may be associated with a slower rate of PTOA development. Clinical Relevance: Less cartilage damage at 52 weeks was found in the surgical group that continued to protect the limb from full body weight during gait. This finding suggests that protection of the knee from maximum stresses may be important in minimizing the development of PTOA in the ACL-injured knee within 1 year.

“…Trimming and shoeing influence not only the morphology of the hooves [2,5,6] but also their balance [7]. In addition, correlations between hoof morphometric changes with stride length and with changes in joint angles [8][9][10][11][12] are described. Even so, there is little information relating to changes in joint angles and possible correlations with hoof measurements attributed to trimming.…”

It is important to understand the effects of hoof trimming on hoof and limb conformation to maximize its benefits on the health of the appendicular skeleton of horses, thus promoting improvements in athletic performance and sporting longevity with regard to athletic horses. There is little information on possible changes in the angulation of the thoracic limb joints after hoof trimming and correlations between the angulation of the thoracic limb joints with hoof measurements. To that purpose, nineteen Mangalarga mares received routine hoof trimming. Visual recordings (photographs) were taken before and after the procedure. Differences (p < 0.05) were found in hoof length, toe angle, heel angle, medial heel height, and metacarpophalangeal angle. Before trimming, correlations were found between frog length and scapulohumeral angle (SH) (r = −0.457; p = 0.049), and between toe length and shoulder-ground angle (SG) (r = −0.553; p = 0.049). A correlation was also seen between the distance from the frog to the lateral wall and the SH angle (r = 0.690; p = 0.001). After trimming, there was a correlation between humeroradial (HR) and SH joint angles (r = 0.669; p = 0.002), and the SG and SH angles (r = 0.488; p = 0.034). This study showed an immediate effect of trimming on the toe angle and heel angle and on the metacarpophalangeal joint angle, in addition to correlations between the hoof and proximal joint angles, following trimming, thus evidencing the relevance of trimming not only in hoof morphology, but also in the conformation of the appendicular skeleton of horses.

“…Recent studies have suggested that animal gait analysis using the pressure-sensing walkway system is less time consuming and is especially useful for repeated gait assessments (15). In addition, previous animal gait studies have utilized the pressure-sensing walkway system and validated the methodology for use with multiple species such as horses, goats, sheep, dogs, cats, and Sprague Dawley rats (16)(17)(18). However, such sensor systems have not been validated for use with the rhesus monkey, and the corresponding gait measurements have not been investigated.…”

Background: Gait analysis in non-human primate models has been performed to elucidate the neural systems involved in controlling quadrupedal locomotor behavior. This study aimed to use a pressure-sensing walkway to identify characteristics of species-specific quadrupedal locomotion in rhesus monkeys. A total of nine healthy adult female rhesus monkeys (Macaca mulatta) were used for gait analysis. We measured the temporo-spatial and kinetic parameters of quadrupedal gait using a custom-built pressure-sensing walkway and compared the left- and right-side parameters to assess the symmetry of the gait pattern. Results: All temporo-spatial and kinetic parameter values showed no significant differences among the nine rhesus monkeys for both the forelimbs and hindlimbs. However, significant differences were observed between forelimb and hindlimb kinetic parameters such as peak vertical force, vertical impulse, and the percentage of body weight distribution. All kinetic parameter values were higher for the forelimbs than for the hindlimbs. These data indicated that the center of gravity in healthy rhesus monkeys is located at the forelimbs rather than at the hindlimbs while walking. Furthermore, the symmetry indices considered for symmetric gait pattern showed a low variability. Most median symmetry index values were nearly zero, indicating no difference between the right and left sides. Conclusions: This study described valid methods for assessing gait parameters and demonstrated rhesus-specific characteristics of quadrupedal locomotion, providing a basis for the assessment of gait normality in rhesus monkeys.
