2.Correlation Analysis of KT 2000 arthrometer, Cybex Isokinetic Test and Lysholm Knee Score in ACL deficient knees.
Journal of the Korean Knee Society 2002;14(2):173-179
PURPOSE: The authors performed correlation analysis among the values of KT 2000 arthrometer, Cybex isokinetic test, and Lysholm knee score to reveal the clinical significance and their role in functional evaluation of ACL insufficiency. MATERIALS AND METHODS: Fifty-one patients with isolated ACL insufficiency were evaluated with KT 2000 arthrometer (15, 20, 30 lb, max.manual), Cybex isokinetic test (60 & 180 degrees/sec), and Lysholm knee score. Correlation analysis was performed between the values of the tests. RESULTS: The Lysholm knee scores had significant linear correlation with the values of KT 2000 of maximal manual difference (r=0.587, P<0.05). The Lysholm knee score had significant linear correlation with all the values of Cybex test of hamstring & quadriceps muscle weakness (r=0.585, 0.635, 0.656, 0.720, p<0.05). The degree of muscle weakness and maximum manual difference in KT 2000 did not show any linear correlation. The time lap between injury and evaluation did not show any correlation with any of the above parameters. CONCLUSION: Lysholm knee score appears to be mostly influenced by the degree of muscle weakness than anterior displacement. The values of KT 2000 of maximal manual difference revealed to be best correlated with Lysholm knee score. The time interval after injury cannot be clinically correlated with muscle weakness or Lysholm knee score.

Tensor of vastus intermedius is a newly discovered muscle located between vastus lateralis and vastus intermedius. The purpose of this study was to investigate the detailed morphology of tensor of vastus intermedius, specifically to provide data pertaining to the attachments, innervations, variation in the types and its morphometry in South Indian population. The tensor of vastus intermedius was studied in thirty six cadaveric lower limbs using macrodissection techniques. The origin of the muscle was from upper part of intertrochanteric line and anterior part of greater trochanter of femur inserted to medial aspect of upper border of patella. The muscle was classified into four types based on the origin and also the aponeurosis course with independent type (type 1) being common. The mean and standard deviation of the length of tensor of vastus intermedius and aponeurosis were 145.40±37.55 mm and 193.55±42.32 mm, respectively. The results of the study suggest that tensor of vastus intermedius is variable and the information provided regarding the attachments, types and quantitative data will contribute to the existing knowledge of the muscle.

Baker's cysts are one of the most common cystic lesions around the knee joint and mainly caused by fluid distension of the gastrocnemius-semimembranous bursa that is situated along the medial side of the popliteal fossa. Typically, a Baker's cyst extends along the intermuscular planes around the knee joint and may enlarge any direction. However, it is mostly located in the inferomedial or superficial layers of the knee joint and less commonly extends laterally or proximally. Expansion of the cyst tends to respect the intermuscular planes, and Baker's cysts along the intramuscular route have been rarely reported. Thus, we report a case of Baker's cyst with intramuscular extension into the vastus medialis muscle.

The aim of this study is to evaluate the contractile properties of thigh muscles in bodybuilders through tensiomyography (TMG). Our hypothesis is that maximal displacement (Dm) in bodybuilders would be lower than in controls because Dm is increased when the muscle is stiffed or hypertrophied. Nine bodybuilder athletes and 15 university students were assessed by TMG. The biceps femoris (BF), semitendinosus (ST), vastus lateralis, vastus medialis (VM), and rectus femoris (RF) were evaluated. The TMG parameters obtained for each muscle were Dm, contraction time (Tc). And we calculated contraction velocity (Vc) as the rate of the radial displacement occurring during the time period of Tc with respect to Tc. Dm values of all muscles in bodybuilders were significantly higher compared to the control group. There were no significant differences in Tc values of most muscles except right BF and ST muscles. Vc values of VM, RF, and ST muscles were lower in bodybuilders than in the control group. This is the first report about TMG assessment of muscle hypertrophy. We found that Dm was most effective in detecting muscle hypertrophy and muscle stiffness secondary to muscle hypertrophy could induce decrease in Dm and Vc.

OBJECTIVE: The aim of this study was to develop objective evaluation method of spasticity which reflects the characteristics of lengthening velocity-dependent stretch reflex of spasticity. METHOD: Kinematic analysis for knee angle and rectus femoris muscle lengthening parameters, and dynamic EMG were performed simultaneously during pendular movement of spastic lower leg for thirty two patients with spasticity and ten normal control subjects. Angular parameters consist of angular relaxation index (ARI), maximal angular velocity (MAV), angular threshold (AT) and angular velocity threshold (AVT). And lengthening parameters consist of lengthening relaxation index (LRI), maximal lengthening velocity (MLV), lengthening threshold (LT) and lengthening velocity threshold (LVT). RESULTS: 1) ARI, MAV, AT, and AVT according to Modified Ashworth scale (MAS) were 1.32+/-0.11, 303.84+/-45.11 deg/sec, 44.19+/-13.81 deg, 262.15+/-33.54 deg/sec in MAS I, 1.16+/-0.16, 279.92+/-42.94 deg/sec, 30.33+/-6.02 deg, 247.65+/-35.92 deg/sec in MAS II, and 0.95+/-0.14, 241.31+/-19.98 deg/sec, 20.55+/-2.68 deg, 209.11+/-48.11 deg/sec in MAS III (P<0.05). 2) LRI, MLV, LT, and LVT according to MAS were 1.27+/-0.11, 0.58+/-0.07, 1.164+/-0.14, 0.53+/-0.05 in MAS I, 1.12+/-0.09, 0.53+/-0.05, 1.150+/-0.08, 0.42+/-0.04 in MAS II, and 0.99+/-0.10, 0.44+/-0.01, 1.137+/-0.15, 0.36+/-0.02 in MAS III (P<0.05). 3) There were significant correlation between various pendulum test parameters and MAS. CONCLUSION: Muscle lengthening parameters as well as knee angular parameters were sensitive parameters reflecting the degree of spasticity. LVT is the most sensitive parameter among all parameters (p<0.01).

OBJECTIVEThe objective of this anatomic study was to investigate the intramuscular neurovascular configuration and to evaluate whether the muscle could be split into two functional units in transplantation.
METHODSTen fresh cadavers and ten preserved cadavers were used in the study. A mixture of lead oxide, gelatin and water was injected to the femoral artery of the fresh cadaver. The rectus femoris muscle with its neurovascular pedicles was dissected and radiographed.
RESULTSThree vascular patterns of the rectus femoris muscle were found in the 40 cadaver legs. The muscle received its blood supply through a single vascular pedicle (12.5%), or a dominant pedicle with 1-2 ramified (80%), or two dominant vascular pedicles (7.5%).
CONCLUSIONSThe study provided a detailed description on the intramuscular neurovascular territories of the rectus femoris muscle. Based on the neurovascular supply of the muscle, it is possible to subdivide the muscle into two functional units for segmental muscle transfer.

Nine patients, who had ten painful bipartite patellae, were managed with a new operative tech nique in which the vastus lateralis insertion to the painful patellar fragment is detached subpe riosteally while the continuity of the tendon-periosteum complex to the main portion of the patella is preserved. A grossly mobile patellar fragment was removed in 3, fragment that showed minimum mobility was left in situ in 5 and fragment that had significant articular component was fixed with 4.0 mm cancellous screw in one. All of the patients had prompt relief of pain and returned to full sports activity within three months of the operation, 2 of 5 patellas that had not been removed united by bone to the main portion of the patella within 2 years post-operatively. Overall, 10 knees had excellent results at an average of four years post-operatively.

9.Diagnosis and Treatment for Delayed Pseudoaneurysm of Deep Femoral Artery: A Case Report.
The Journal of the Korean Orthopaedic Association 2008;43(1):118-121
Post-traumatic arterial injuries are often reported in crushing or penetrating gun-shot injuries that include massive soft tissue damage. In most cases, the injured arteries are treated with early repair or reconstruction surgery. When there is a delayed in diagnosis, a pseudoaneurysm might be detected several weeks or months after the trauma. Pseudoaneurysms after femoral fracture are usually detected in the superficial femoral arteries, but rarely in the very deep femoral arteries, which are protected by the vastus medialis. There are many reports on post-traumatic pseudoaneurysms, most of which are in the superficial femoral arteries, and there are few reports with normal findings in an early angiogram. We report a pseudoaneurysm of the deep femoral artery with a normal angiogram in the early stage that was diagnosed and treated 4weeks after the trauma.

PURPOSE: This study is designed to evaluate the reliability for studies of tensiomyography (TMG). TMG can evaluate muscle function noninvasively and selectively. METHODS: We measured 12 male volunteers (age, 26.5±7.6 years; height, 175.3±4.7 cm; weight, 78.8±13.3 kg) in this study and measured TMG during three occasions over 3 consecutive days. None of the participants has had any history of neuromuscular disorders or muscle diseases. Vastus lateralis, vastus medialis (VM), rectus femoris (RF) in quadriceps and biceps femoris, semitendinosus in hamstrings muscles were measured. Coefficient of variation (CV%) and intraclass correlation coefficient (ICC) have been calculated about maximal displacement (Dm, mm) and contraction time (Tc, ms) which are main parameters. RESULTS: Most of the ICC of Dm were over 0.8 and the highest among the muscles except both VM. And, most ICC of Tc was lower than Dm except both BF (right, 18.31; left, 15.03). But, the ICC of Tc was lower than Dm except left RF (0.890) and VM (0.859). CONCLUSION: This study has shown that the Dm is high levels of the ICC and CV(%) in thigh muscle except VM. In the future, we plan to establish the method of measurement more clearly for reducing the errors of measurements. The technique of correct palpation of measurable muscles using TMG devices is also necessary.
