The Lachman and pivot-shift tests are 2 standard manual to diagnose anterior cruciate ligament (ACL) insufficiency. However, the global variation of these testing procedures is not known.To survey currently used techniques measure knee movement during among various expert surgeons from across globe.Controlled laboratory study.Part 1: descriptive survey. A questionnaire asking about was conducted 33 ACL surgeons. Part 2: kinematics comparison. were performed on a unilateral ACL-injured...
Abstract Introduction Previous studies have reported that alignment changes depend on the patient’s position in orthopedic surgery. However, it has not yet been well examined how affects preoperative planning high-tibial osteotomy (HTO). Therefore, aim of this study was to investigate effects HTO. Materials and methods A total 60 knees 55 patients who underwent HTO were retrospectively examined. Virtual for medial open-wedge (OWHTO), lateral closed-wedge (CWHTO), hybrid CWHTO performed by...
The pivot shift test is a commonly used clinical examination by orthopedic surgeons to evaluate knee function following injury. However, the can only be graded subjectively examiner. Therefore, purpose of this study develop software for computer tablet quantify anterior translation lateral compartment during test. Based on simple image analysis method, was developed with primary design constraint - should easy use in setting and it not slow down an outpatient visit. Translation intact 2.0 ±...
The femoral and tibial bone tunnel enlargement after anatomic double-bundle anterior cruciate ligament reconstruction (ACL-R) has not been fully documented.To evaluate the region-specific volume changes those transpositions using 3-dimensional multidetector-row computed tomography (MDCT) ACL-R.Case series; Level of evidence, 4.Eleven patients who underwent unilateral ACL-R with hamstring tendon autografts were included in this study. MDCT scanning their knees was performed at 3 weeks 1 year...
The anterior cruciate ligament (ACL) does not heal spontaneously after injury, and ACL patients of different ages respond differently to treatment. Although ACL-derived CD34-positive cells contribute bone-tendon healing reconstruction, the relationship between potential a patient's age is unknown.ACL-derived from young will have greater effect on maturation integration in an immunodeficient rat model reconstruction compared with derived older patients.Controlled laboratory study.Sixty...
Anatomic anterior cruciate ligament (ACL) reconstruction is common procedure performed by orthopedic surgeons, particularly in association with sports-related injuries. Whereas traditional techniques used a single bundle graft that was typically placed non-anatomic position, renewed interest anatomy has facilitated the popularization of anatomic techniques. Recently, focus been on individualizing ACL surgery based each patient's native anatomical characteristics (e.g., insertion site size,...
This study aimed to examine the effects of SRT1720, a potent SIRT1 activator, on osteoarthritis (OA) progression using an experimental OA model.Osteoarthritis was surgically induced by destabilization medial meniscus in eight-week-old C57BL/6 male mice. SRT1720 administered intraperitoneally twice week after surgery. Osteoarthritis evaluated histologically Research Society International (OARSI) score at four, eight, 12 and 16 weeks. The expression SIRT1, matrix metalloproteinase 13 (MMP-13),...
Simvastatin is clinically used for the treatment of hypercholesterolaemia. This study investigated effects intra-articular administration a simvastatin-conjugated gelatin hydrogel on osteoarthritis (OA) progression in murine model. The medial meniscus knee joint was de-stabilized to induce OA 10-week-old mice. Mice were then intra-articularly injected with dimethyl sulfoxide (control), drug-free hydrogel, simvastatin, or hydrogel. At 8 weeks postsurgery, significantly attenuated...
In knee arthroscopic surgery, fibrin clot (FC) and leukocyte-rich platelet-rich (L-PRF) may be used in augmentation for meniscal repair. Studies have investigated growth factors released from FC L-PRF; however, it is difficult to compare L-PRF between different studies. Direct comparison of that support healing beneficial deciding whether use or L-PRF. If no significant difference seen, the surgeon decide which easier prepare compared The purpose this pilot study investigate release amount...
No study has examined the possible factors associated with different characteristics of stem-like cells derived from anterior cruciate ligament (ACL) remnants. And purpose is to elucidate whether demographic are healing potential ACL remnants tissue. Thirty-six were harvested patients who received primary arthroscopic reconstruction. Interval injury surgery, age, sex, and combined meniscal or chondral injuries analyzed. Cells isolated remnant tissues their was evaluated by: 1)...
Rotator cuff tears are a significant clinical problem. Tears in the anterior supraspinatus might behave differently compared to central due differences regional structural properties. The objective of this study was determine strain distributions for tendon and relationship tear propagation during cyclic loading. It hypothesized that highest maximum principal would be posterior tear, propagate direction strain. Eight human cadaveric tendons with surgically created small third were tested...
Vascular CD34+ cells in anterior cruciate ligament (ACL) tissue have the potential for high proliferation and multilineage differentiation that can accelerate tendon-bone healing. While patient characteristics, such as age, affect healing, influence of elapsed time after injury on healing process is unclear.Cells obtained during early phase will exhibit a greater compared with chronic counterparts when applied to an immunodeficient rat model ACL reconstruction.Controlled laboratory...
