13122. Anatomical reconstruction of knee posterolateral complex with the tendon of the long head of biceps femoris. (Abstract)

was performed consecutively in 28 patients with chronic posterolateral knee injuries. Two distally pedicled tendon slips more than 16 cm long were created from the tendon of the long head of the biceps femoris. The posterior tendon slip was used to reconstruct the popliteofibular ligament and popliteus tendon, and the anterior slip were doubled to reconstruct the lateral collateral ligament. The patients were followed up for 2 to 4 years.At the latest follow-up, examinations showed that 96.4% (27/28 (...) ) of the patients had a normal or nearly normal reconstructed fibular collateral ligament as judged by manual examination. All patients had a normal or nearly normal reconstructed popliteofibular ligament and popliteus tendon as judged by manual examination.Anatomical reconstruction of the knee posterolateral complex with the tendon of the long head of biceps femoris is effective in restoring knee posterolateral stability.

13123. Digital radiographic evaluation of medial joint space narrowing after partial meniscectomy of bucket-handle medial meniscus tears in anterior cruciate ligament-intact knees. (Abstract)

medial meniscectomy, intact ligaments, no surgery to the contralateral knee, and no chondromalacia greater than grade II. Seventy-nine patients living within 150 miles of the clinic were asked to return for physical examination. Joint space narrowing was measured from the middle of the femoral condyle to the middle of the tibial plateau using digitally magnified weightbearing 45 degrees flexed posteroanterior and full-extension anteroposterior radiographs. Measurements were performed twice (...) with the observer blinded to the previous measurements. Subjective follow-up was obtained prospectively on an annual basis with International Knee Documentation Committee and modified Noyes knee questionnaires.Forty-nine patients were examined at a mean of 11.8 years postoperatively. Mean medial joint space narrowing was 1.2 +/- 0.5 mm on 45 degrees flexed posteroanterior radiograph and 0.2 +/- 0.9 mm on full-extension anteroposterior radiographs (P < .001).

13124. Ultrasound Doppler of the anterior knee tendons in elite badminton players Colour fraction before and after match. (Abstract)

Ultrasound Doppler of the anterior knee tendons in elite badminton players Colour fraction before and after match. Anterior knee tendon problems are seldom reported in badminton players although the game is obviously stressful to the lower extremities.Painful anterior knee tendons are common among elite badminton players. The anterior knee tendons exhibit colour Doppler activity. This activity increases after a match. Painful tendons have more Doppler activity than tendons without pain.Cohort (...) study.72 elite badminton players were interviewed about training, pain and injuries. The participants were scanned with high-end ultrasound equipment. Colour Doppler was used to examine the tendons of 64 players before a match and 46 players after a match. Intratendinous colour Doppler flow was measured as colour fraction (CF). The tendon complex was divided into three loci: the quadriceps tendon, the proximal patellar tendon and the insertion on the tibial tuberosity.Interview: Of the 72 players

13125. Effect of proprioception training on knee joint position sense in female team handball players. (Abstract)

in the intervention team followed a prescribed proprioceptive training programme while 19 players in the control team did not have a specific propioceptive training programme. The coaches recorded all exposures of the individual players. The location and nature of injuries were recorded. Joint position sense (JPS) was measured by a goniometer on both knees in three angle intervals, testing each angle five times. Assessments were performed before and after the season by the same examiner for both teams (...) Effect of proprioception training on knee joint position sense in female team handball players.

13126. Angle specificity of the knee extensor age-related profile in young female athletes. (Abstract)

Angle specificity of the knee extensor age-related profile in young female athletes. The angle specificity of the knee extensor age-related profile was examined in young females (13-19 yr). Twenty-one track & field jumpers, 20 volleyball players and 20 non-active females were separated into the youngest and the oldest age categories, based on the official competitive age categories. The maximum knee extensor isometric torque (T MAX) was measured at 9 knee angles. The relationships between T MAX (...) extended, or more flexed, knee angles. Significant quadratic R2 joint angle trend lines were found in all track & field jumpers (p < 0.05) and, in the youngest only volleyball players (p < 0.05), but not in the non-active females (p > 0.05). In conclusion, the knee extensor profiles of young female athletes show an age-related angle specificity that should be accounted for when treating athletes within the age range examined.

13127. Effect of soccer shoe cleats on knee joint loads. (Abstract)

Effect of soccer shoe cleats on knee joint loads. Noncontact injuries frequently occur during soccer matches and training. The purpose of this study was to examine the influences of different soccer shoe studs to kinematic, kinetic and electromyographic parameters in the knee joint. Six male soccer players performed complex turning movements (180 degrees ) with bladed and round studded soccer shoes. Ground reaction forces, 3-D kinematics and electromyographic activity of the lower leg muscles (...) were recorded. Calculated external knee joint moments were similar with both stud configurations, although there was a trend towards increased vertical and anterior-posterior ground reaction forces with blades. Electromyography evidenced significantly higher activation of m. quadriceps femoris (p = 0.02) with round studs during initial phase of stance. In conclusion, comparison of soccer shoes with round and bladed studs showed no significant differences in externally applied knee joint loads

13128. Functional eccentric-concentric ratio of knee extensors and flexors in pre-pubertal children, teenagers and adult males and females. (Abstract)

Functional eccentric-concentric ratio of knee extensors and flexors in pre-pubertal children, teenagers and adult males and females. The purpose of this study was to examine the age and sex associated differences in the eccentric/concentric functional ratio for the knee. Isokinetic concentric and eccentric knee extension and flexion was measured at 0.52 rad x s (-1) and 3.14 rad x s (-1) in 121 subjects. Other than mass there were no significant age-by-sex interaction effects for all variables (...) teenagers and adults. The results of the current study suggest that functional rather than conventional ratio should be used when examining knee stability. During fast velocity movements, prepubertal children have a lower capacity for generating eccentric compared to concentric torque. The lower CON (KF)/ECC (KE) ratio in adults appears to be due to a greater ability to generate large eccentric torques at all slow and fast movement velocities. The lower CON (KF)/ECC (KE) ratio in females is a product

13132. A phase I/IIa study on intra-articular injection of holmium-166-chitosan complex for the treatment of knee synovitis of rheumatoid arthritis. (Abstract)

A phase I/IIa study on intra-articular injection of holmium-166-chitosan complex for the treatment of knee synovitis of rheumatoid arthritis. Previous animal studies have established that the intra-articular injection of holmium-166-chitosan complex (DW-166HC) causes effective necrosis of the inflamed synovium with litle leakage of radioactivity from the injected joint. Based on these findings, we conducted a phase I/IIa study to examine the biodistribution of DW-166HC and to assess the safety (...) of DW-166HC for the treatment of knee synovitis in patients with rheumatoid arthritis (RA). A total of 16 patients [1 man, 15 women; median age 49 (range 36-65) years] who had RA knee synovitis refractory to disease-modifying anti-rheumatic drug treatments of > 3 months' duration were randomly assigned to three treatment groups with different radiation doses of DW-166HC: 370 MBq (n = 6), 555 MBq (n = 5) and 740 MBq (n = 5).

13134. A comparative study of the postoperative allogeneic blood-sparing effects of tranexamic acid and of desmopressin after total knee replacement. (Abstract)

A comparative study of the postoperative allogeneic blood-sparing effects of tranexamic acid and of desmopressin after total knee replacement. Tissue hypoxia and reperfusion induce abnormal hemostatic function. Therefore, bleeding after total knee replacement (TKR) may be a result of a tourniquet-induced imbalance of the procoagulant and fibrinolytic systems. Because laboratory confirmation of tourniquet-induced abnormal hemostasis is difficult to obtain, indirect evidence must be sought.A (...) <27 percent constituted the postoperative transfusion trigger. Patients were examined daily for signs of lower-limb deep vein thrombosis, and they underwent lower-limb Doppler ultrasound on postoperative Day 5. Three months after surgery, the incidence of delayed thromboembolic events was assessed.During the first 12 postoperative hours, blood accumulation in the surgical drain was significantly (p<0.05) lower in the TA group (162 mL +/- 129) than in the desmopressin group (342 mL +/- 169).

13137. Graft tension and knee stability after anterior cruciate ligament reconstruction. (Abstract)

Graft tension and knee stability after anterior cruciate ligament reconstruction. This study examined the effect of the initial graft tension on the clinical outcome of anterior cruciate ligament reconstruction in a prospective randomized design. Fifty patients were enrolled in the study. In the reconstructive procedure, a bone-patellar tendon-bone graft was used. A set force of 25 N (5.6 lb) was applied in 25 patients and 50 N (11.2 lb) tension was maintained during fixation for the remaining (...) 25 patients with the knee in full extension. In the immediate postoperative period, the anterior cruciate ligament reconstructed knee was similarly overconstrained in both groups. At 3 months, laxity of the surgically treated knee in both groups had increased significantly and become close to that of the contralateral knee. Measured laxity value showed a slight increase between 3 and 6 months, and remained similar thereafter. No significant difference in the clinical outcome was observed between

13139. Intrathecal morphine for postoperative analgesia: a randomized, controlled, dose-ranging study after hip and knee arthroplasty. (Abstract)

Intrathecal morphine for postoperative analgesia: a randomized, controlled, dose-ranging study after hip and knee arthroplasty. In this series, we examined analgesia and side effects of intrathecal morphine sulfate (ITMS) after hip and knee arthroplasty over a dose range of 0.0-0.3 mg. Eighty patients undergoing hip (n = 40) or knee (n = 40) arthroplasty were randomized to receive ITMS (0.0, 0.1, 0.2, or 0.3 mg). A patient-controlled analgesia (PCA) device provided free access to additional (...) receiving 0.2 or 0.3 mg of ITMS were more satisfied with their pain control than those receiving 0.0 or 0.1 mg after both hip and knee arthroplasty. Analgesic needs are greater after knee arthroplasty than after hip arthroplasty. We conclude that combining small-dose (0.2 mg) ITMS with PCA morphine provides good to excellent pain control in most patients after total hip or knee arthroplasty. However, PCA morphine use was reduced by the addition of ITMS only after hip arthroplasty.This series examined
