Objective To explore the therapeutic efficacy of arthroscopic reconstruction of anterior cruciate ligament (ACL) with autologous multistranded semitendinous tendon (ST). Methods From September 2000 to December 2004, 50 casesof ruptures of ACLs were diagnosed by clinical and arthroscopic examinations. There were 32 males and 18 females with an average age of 26.3 years (18-51 years). The locations were left knee in 31 cases and right knee in 19 cases. All patients had the history of knee joint injury. Arthroscopy showed 26 cases of rupture, 14cases of defect, 4 cases of avulsion and 6 cases of laceration. All patients were operated upon arthroscopically by using autologous multistranded ST. Plaster splints were used for 4 weeks after operation. The result was estimated by AO Yingfang’s standards and Lysholm knee scores. Results All patients achieved healing bythe first intention. The extension and flexion function was restored normal at 8-10 weeks. The patients were followed up averagely 1 year and 8 months (6.48 months). The results of drawer test and Lachman test were positive in 3 cases and suspiciously positive in 8 cases. The results were excellent in 23 patients, good in 18 and fair in 9. Lysholm knee scores were 4057±1068 preoperatively and 86.43±9.33 postoperatively, showing significant difference (P＜0.01). Conclusion Arthroscopy reconstruction of ACL with autologous multistranded ST may be one of the excellentmethods bringing less injury.
A new method of transfer of the nasolabial skin flap, the myocutaneous flap with pediculated guadratus labii superioris muscle was introduced. It was applied in 9 cases mid-face defects with satisfactory results. The applied anatomy and the its operative technique were briefly discussed.
ObjectiveTo summarize the experience of colon interposition for esophageal replacement. MethodThe clinical data of 108 consecutive patients underwent colon interposition for esophageal replacement in our hospital between January 2005 and March 2013 were reviewed for benign and malignant lesions. Their ages ranged from 2 to 71 years (mean age at 34.3 years). There were 81 males and 27 females. ResultThere was no surgical death. Esophago-colic anastomotic insufficiency occurred in 7 patients. One case of graft necrosis was observed. Injury of recurrent laryngeal nerve occurred in 8 patients, incomplete intestinal obstruction in 2 patients, and wound infection of the abdominal wall in 1 patient, and deep venous thrombosis in 1 patient. In-hospital mortality was 15.7% (17/108). The postoperative follow-up was made for 12 months in 97 patients (91.5%) and all of them were alive. The patients' body weight and appetite improved. ConclusionColon interposition is a valuable alternative with a good long-term function.
ObjectiveTo compare the effectiveness of anterior cruciate ligament (ACL) reconstruction between by long fibular muscle tendon and by hamstring tendon under arthroscopy after ACL rupture. MethodsBetween February 2010 and December 2012, 56 cases of ACL rupture underwent ACL reconstruction under arthroscopy. The long fibular muscle tendon was used in 26 cases (group A) and the hamstring tendon was used in 30 cases (group B). There was no significant difference in gender, age, side, disease duration, and preoperative Lachman test, Lysholm score, and the International Knee Documentation Committee (IKDC) score between 2 groups (P>0.05). The treatment after operation was identical in 2 groups. ResultsPrimary healing of incision was obtained after operation in 2 groups. There was no major neurovascular injury and knee synovitis. There was no significant difference in operation time, hospitalization time, and postoperative 24-hour drainage volume between 2 groups (P>0.05). The patients were followed up 25-32 months (mean, 28 months) in group A, and 27-37 months (mean, 31 months) in group B. There was no related complication at donor site in 2 groups. MRI examination showed good ACL reconstruction. The Lysholm score and the IKDC score of group A at 6 months after operation were significantly better than those of group B (P<0.05), but no significant difference was found between 2 groups at 2 years after operation (P>0.05). There was no significant difference in Lachman score between 2 groups at 6 months and 2 years after operation (P>0.05). ConclusionThe long fibular muscle tendon for arthroscopic reconstruction of ACL has much simpler operation, earlier knee function recovery, and better subjective satisfaction than the hamstring tendon.
Objective To summarize the clinical experiences of various types of the second dorsal metacarpal artery (SDMA) flap for hand reconstruction. Methods From 1988 to 2003, 139 SDMA flaps were transferred for hand injuries. The flaps were used in 5 types according to vascularization and technique in transplantation:orthograde pedicled island SDMA flaps in 37 cases (cutaneous in 24and teno-cutaneous in 13), retrograde pedicled island SDMA flaps in 25 cases(cutaneous in 19 and teno-cutaneous in 6),double pivot SDMA flaps in 36 cases(cutaneous in 28 and teno-cutaneous in 8), distal perforator branch pedicledflaps in 19cases (cutaneous in 16 and composite in 3), free SDMA flaps in 22 cases (cutaneous in 15 and composite in 7). The skin islands were 3.0 cm×1.5 cm to 6.3 cm×5.0 cm in size. Results Of the 139 flaps, 135 flaps survived completely, 3 survived partially, and1 failed in the operation because of intractable vascular spasm. Follow-up wasdone in 116 cases for 12 to 57 months. The flap had good texture and color match. The twopoint discrimination was 5 to 9 mm in 78 sensate flaps, while it was 10 to 15 mm in 38 nonsensate flaps. In 21 tenocutaneous flaps, the TAM score of range of motion was 60% to 70% of the healthy side. Conclusion The SDMA flap has a constant and reliable vessel and a thin, pliable, and good-quality skin. It is versatile in creatingcomposite flaps. It is a good flap resource for hand and finger reconstruction.
Objective To investigate the effectiveness of meniscal allograft in treatment of discoid meniscus tear. Methods Between May 2005 and September 2009, 7 cases of discoid meniscus tear were treated with meniscal allograft. There were 2 males and 5 females with an average age of 22.6 years (range, 18-33 years). The locations were the left knee in 5cases and the right knee in 2 cases. The causes were sport trauma in 4 cases, impact injury in 2 cases, and no apparent reason in 1 case. Of them, 7 cases had joint tenderness gap, 2 cases had positive results in floating patella test, 7 cases had positive results in McMurray test, and 6 cases had positive results in squatting test. The range of knee motion was 0-60°. The disease duration ranged from 3 months to 17 years (median, 26 months). Results The number of the pins was 9-13 (mean, 11). The operative time ranged from 1.5 to 2.7 hours (mean, 1.7 hours). The postoperative fever time ranged from 31 to 57 hours (mean, 46.4 hours). Incisions healed by first intention in 6 cases; infection occurred in 1 case after operation and was cured after 18 days of local irrigation with antibiotic sal ine. Seven patients were followed up 21.6 months on average (range, 12-53 months). The range of knee motion was 0-125°. All patients had the negative results of floating patella test, McMurray test, and squatting test. MRI showed that there was a good heal ing between the transplanted meniscus and the surrounding synovium. The Japanese Orthopaedic Association (JOA) score was 80.71 ± 4.82 at 6 months after operation, showing significant difference (t=10.11, P=0.00) when compared with the score (41.71 ± 8.07) before operation. Conclusion Meniscal allograft in treatment of discoid meniscus tear is a rel iable and effective method, which can ease knee pain.
OBJECTIVE: To investigate the clinical effect of reconstructing anterior cruciate ligament by using a bone-patellar tendon-bone autograft under arthroscopy. METHODS: Among 13 patients with anterior cruciate ligament injury, there were 9 males and 4 females(aged 23-45). Their anterior cruciate were reconstructed by applying the mid-one third autologous bone-patellar tendon-bone strip in -press fit technique under arthroscopy. The result was positive in 13 cases in anterior drawer test, in 4 cases in pivot shift test and in 7 cases in Lachman’s test preoperatively. RESULTS: The follow-up period was 5-25 months averaged 15 months. The results of the above tests were negative in all the patients. According to Boszotta’s evaluation quota, the results were excellent in 9 cases, good in 3 cases and fair in 1 case. The knee stability improved obviously in all patients. CONCLUSION: Anterior cruciate ligament injury can be treated by arthroscopic reconstruction with autologous bone-patellar tendon-bone strip and the clinical result of short-term followup is satisfactory.
From 1987, in 4 cases having muscle damage associated with extensive skin defeet, the repair was carried out by anastomosing the neurovascular pedicle of the free latissimus dorsi myocutaneous graft with the host. The patients were followed up from 6 months to 3 years. The muscle power of the injured part following repair had returned to about 4 degrees, and the external appearance and the function were satisfactory. The advantages and disadvantages of this operation, the preparation of the recipient area and the management of the tendon were discussed.
To fix the ligaments, tendons or other transplantation materials by passing through bone channels was commonly used and a relialde method in the reconstruction of joint stability. Usually an additional incision was necessary on the side of the outlet of the bone channel, that the screws, plates or U-shaped staple could be applied. An instrument was designed that the steel miniplate could be fixed to the bone by noninvasive method. This technique was applied in 20 cases in which anterior cruciate ligament in 14, posterior cruciate ligament in 4, and collateral ligaments in 2 with carbon fibers. The result was successful in all patients. It was shown that it gave simple manipulation, reliable fixation and no need to have an additional incision, and it could lessen patients’ suffering and lead to satisfactory clinical result.
