Objective and Subjective Analysis of the Knee Joint Function Using Lower Extremity Assessment Protocol after Anterior Cruciate Ligament Reconstruction / 대한스포츠의학회지

Purpose@#Anterior cruciate ligament reconstruction (ACLR) is one of the most common procedures in sports medicine.It is important for patients to determine whether or not to return to the pre-operative state after the ACRL. This study is to evaluate the objective and subjective analysis of the knee joint function and to compare between injured knee and non-injured knee in those with ACLR.Methods: This cross-sectional study recruited 15 individuals with ACLR using autograft (age, 27.87±4.10 years; height, 172.56±4.81 cm; weight, 75.51±13.03 kg; time to surgery, 27.11±14.03 months). International Knee Document Committee subjective knee evaluation form and Lower Extremity Assessment Protocol (LEAP) including muscle strength, static and dynamic postural control, functional task was used to assess the knee joint function. Deficit ratio between injured knee and non-injured knee and independent t-test were used for analysis. @*Results@#Injured knee has significantly decreased isokinetic extension strength (90º/sec), isometric flexion strength and one-leg hopping distance (p＜ 0.05). @*Conclusion@#Although individuals who successfully returned to play (RTP) did not experience subjective dysfunction and pain, there are items of LEAP that indicates deficit ratio between injured knee and non-injured knee. Therefore, when considered whether and when to RTP, it is very important to assess not only subjective dysfunction and pain but also whether the patient has recovered to a level similar to that of the non-injured knee in various aspects of the knee joint.

Effects of Reduced Plantar Cutaneous Sensation on Static Postural the Kinematic Strategy Control in Individuals with or without Chronic Ankle Instability / 대한스포츠의학회지

PURPOSE: To investigate the alteration of lower extremity movement during maintaining balance test with their eyes closed in chronic ankle instability (CAI) patients compared to healthy group with and without plantar cutaneous sensation. METHODS: Ten healthy volunteers (age, 23.40±2.22 years; height, 165.42±6.67 cm; weight, 60.93±13.42 kg) and 10 CAI patients (age, 23.90±2.56 years; height, 166.89±10.50 cm; weight, 67.43±12.96 kg), were recruited. Subjects immersed both feet in an ice water for 10 minutes and performed three trials of a single-leg stance balance test with their eyes closed while standing on a force plate for 10 seconds. RESULTS: CAI group showed increased knee flexion, reduced knee external rotation, and hip internal rotation compared to the healthy group from single-limb stance with eyes closed after diminished plantar cutaneous sensation. However, there was no significant interaction between group and time. CONCLUSION: These findings indicate that the postural kinematic analyses revealed that individuals with CAI used different strategy of controlling their lower extremities, which alters transverse plane motion of hip and knee compared to the healthy group in order to compensate for their ankle deficits after freezing the plantar cutaneous.

Ventriculotransverse Sinus Shunt for Hydrocephalus

The new operative technique of ventriculotransverse sinus shunt for hydrocephalus is introduced in this paper. This method has been applied to 6 hydrocephalic patients with Pudenz-Heyer low pressure valve in our department of Kyungpook National University Hospital from June 1990 to to May 1992. 4 cases including 2 high pressure hydrocephalus of all the patients improved in neurologic deficit within 2 weeks postoperatively. 2 Cases of normal pressure hydrocephalus installed the same shunt showed no improvement without any shunt valve dysfunction, so the shunts were revised to ventriculoperitoneal shunts. The choice of transverse sinus rather than superior sagittal sinus for CSF recipient of shunt seems more reasonable anatomically and physiologically. And this procedure could first apply to the poor risk patients with local anesthesia in such cases with old age, deteriorated, and to the patients requiring revision of the other shunting. To confirm the effect and perspect for continuous using this new technique, more patients applying this method and long term follow-ups of them should be needed.
