    ABSTRACT: To evaluate the clinical outcome of arthroscopic repair method of meniscus injury with Fast-fix under local anesthesia. From October 2005 to September 2012,106 patients with meniscus injuries admitted into our - hospital were studied, including 74 males and 32 females, ranging in age from 13 to 71 years old, averaged 27.6 years old. The duration of the disease ranged from 15 days to 5 years. The main clinical manifestations included knee joint pain after exercise, joint locking, pressing pain of knee joint and positive McMurray signs. The MRI showed meniscus tear or degeneration. Arthroscopic repairing surgeries were performed with Fast-fix under local anesthesia. Each patient was assessed with VAS pain evaluation and Lysholm knee-joint score system before and after operation. All the patients were followed up more than 1 year. One hundred and 2 patients were followed up by recording subjective symptoms, clinical examinations and questions naires for an average of 2.6 years (ranged, 1.1 to 8 years), and 4 patients lost follow-up. All the 102 patients had no anesthetic complications. Ninety-six patients had normal subjective symptom and clinical examinations. Four patients had a mild ache with activities,2 patients had moderate pain after activities with joint space pressing pain. VAS pain evaluation and Lysholm knee-joint score after operation both were much better than that before operation. onclusion: Local anesthesia can provide nice circumstances for surgeries. Arthroscopic repair using Fast-fix is an idea method for meniscus injury, especially for the posterior horn tear of medial meniscus, which is simple and convenient with less complications, and satisfactory results.

    ABSTRACT: To explore the histological outcomes of tendon-bone healing in anterior cruciate ligament (ACL) reconstruction with cortical press-fit bolt (CPB). Twenty-four healthy female or male New Zealand White rabbits (2-3 months old) underwent bilateral ACL reconstruction with extensor digitorum longus tendon. A random method was used to decide one knee would receive the routine ACL reconstruction (control group) and another cortical press-fit bolt fixation (experimental group). After general anesthesia, extensor digitorum longus tendon was harvested and ACL reconstruction performed. All animals were sacrificed at 4, 8 and 12 weeks postoperation. Radiological and histological examinations were made at each timepoint. The specimens were stained with different methods to observe the pathological changes of tendon graft, bone tunnel and cortical press-fit bolt. More revascularization and massive new bone were found in tendon-bone junction of experimental group at 4, 8 and 12 weeks postoperation. The circum-graft new vessel proportion of the experimental and control groups were 0.48 ± 0.12 and 0.26 ± 0.05 respectively (P < 0.05). In the experimental group, more cartilage cells were present in tendon-bone junction at 12 weeks and the circum-graft new bone areas in two groups were 0.41 ± 0.11 and 0.21 ± 0.10 mm(2) respectively (P < 0.05). Cortical press-fit blot may improve tendon-bone healing after ACL reconstruction in rabbits. The application prospects of this procedure are promising.

    ABSTRACT: To evaluate clinical effects of arthroscopic anterior cruciate ligament (ACL) reconstruction with preservation of the remnant bundle. From January 2002 to December 2009, 57 patients with ACL partial rupture were treated with preservation of the remnant bundle. There were 39 males and 18 females, with an average age of 28.5 years old (ranged, 16 to 49 years old). Thirty-three patients had injuries in the left knees,and 24 patients had injuries in the right knees. Forty patients had injuries caused by sports, 7 patients had injuries caused by traffic accidents and 10 patients had injuries caused by daily sprain. The anterior drawer test showed positive results in 23 patients, weakly positive results in 6 cases; Lachman test showed positive results in 19 patients, and weakly positive in 4 patients. Both anterior drawer test and Lachman test showed positive results in 5 patients; and valgus stress test (medial) showed positive results in 24 patients. The mean value of Rolimeter measurement was 8.7 mm, (ranged, 7.5 to 11.5 mm). The mean International Knee Documentation Committee (IKDC) score was 70.0 +/- 7.5 and the Lysholm score was 68.0 +/- 6.3. The duration from injury to surgery was 1 week to 12 months,with an average of 3.1 months. There were 32 patients treated with anteromedial bundle reconstruction and 25 patients treated with poterolateral bundle reconstruction. Fifty-seven patients were followed up, and the mean follow-up time was 22.5 months (ranged, 13 to 37 months). The anterior drawer test and Lachman test were all negative at 1 month post-operation. At the end of the follow-up, the range of motion of all the knees was 120 to 130 degree. There were 54 patients with negative results of anterior drawer test and Lachman test, 1 with weakly positive result of anterior drawer test and 2 with weakly positive results of Lachman test. The measurements of Rolimeter showed excellent stability of the knee. The mean IKDC score was 92.0 +/- 4.9 and the mean Lysholm score was 91.0 +/- 3.7, which all improved compared to preoperative scores. Arthroscopic reconstruction of anterior cruciate ligament with preservation of the remnant bundle has satisfactory effects on the knee stability, which could increase the angiogenesis and collagen of the ACL and improve the proprioception of the knee.

    ABSTRACT: To evaluate therapy effect of radiofrequency in the treatment of painful heel syndrome under arthroscopy. From January 2006 to December 2011, 13 patients with painful heel syndrome being admitted into our hospital were studied. There were 5 males and 8 femals, ranging in age from 35 to 68 years. All these surgeries were performed under local anesthesia. After constructing a man-made lacouna in the subcutaneous tissue above plantar fascia, a medial and a lateral portal were established on both sides of plantar fascia and at the anterior edge of calcaneal tuberosity. Hyperplasia and torn fiber tissue of plantar fascia, and plantar calcaneal bursa were removed with radiofrequency probe under arthroscopy. Then penetration of the plantar fascia was carried out in a reticulation-shaped pattern with a special radiofrequency probe TOPAZ. Each patient was assessed with VAS pain evaluation criteria and AOFAS ankle-hindfoot score system (AOFAS-AH) before and after operation. All the patients were followed up, and the duration ranged from 6 to 12 months. All the 13 patients got excellent recovery with their heel pain relieved significantly. VAS score was 8.71 +/- 1.64 before operation, 6.27 +/- 2.53 at the 1st month after operation, and 2.30 +/- 2.69 at the 6th month after operation. AOFAS-AH score was 56.43 +/- 3.72 preoperation, 68.15 +/- 7.38 at 1st month post operation, and 84.51 +/- 2.93 at 6th month after operation. There were no perioperative and postoperative complications related to the procedure, such as blood vessel and nerve injury, and infection. Plantar fasciitis and plantar calcaneal bursitis are main factors of painful heel syndrome. Due to advantages of being easy to operate, having definite effect and no use to do spur removal or plantar fasciotomy. Endoscopy assisted plantar calcaneal bursa removal and plantar fascia penetration by radiofrequency technique can be a satisfactory treatment method for painful heel syndrome.

    ABSTRACT: To evaluate the efficacies of arthroscopic debridement and removal of osteophyma for olecroanon and olecranon fossa plasty for posterior impingement of elbow joint. Between 1999 and 2008, a total of 21 cases were diagnosed with osteoarthritis and posterior elbow impingement. There were 15 males and 6 females. And there were 16 right and 15 left cases. They included volleyball players (n = 7), tennis players (n = 7), golf enthusiasts (n = 4) and fencers (n = 3). The average duration of onset-operation was 3.5 years (range: 2.5 - 8). Arthroscopic exploration revealed synovial hyperplasia hypertrophy, cartilage degeneration and olecranon fossa hyperplasia with deformed olecranon fossa. Debridement and plasty were performed. Loose bodies were removed from elbow joint in 6 patients. Partial resection of posterior olecranon tip was performed and osteophytes or fibrous tissue removed in this area. Dynamic observation showed no posterior elbow impingement. Postoperative follow-up was conducted in 19 cases and 2 cases became lost to follow-up. The average follow-up period was 25.3 months (range: 18 - 42). All patients were evaluated preoperatively and postoperatively with the Hospital for Special Surgery Elbow Assessment Scale. The outcomes were excellent (n = 12), good (n = 7) and fair (n = 2). Postoperative patients elbow swelling and pain relieve, sports and life function returns to normal, elbow flexion and rotating mobility obviously improved. With the elbow radiological films to measure the range of motion, the average range of motion was 90.5° preoperatively and improved to 130° postoperatively. There was significant improvement in all cases. Posterior elbow impingement is caused by hyperextension trauma and elbow overuse during specific sporting activities. Arthroscopic debridement and olecroanon or olecranon fossa plasty demonstrates excellent results for posterior impingement of elbow joint.

    ABSTRACT: Medial patellofemoral ligament (MPFL) reconstruction is the preferred operative treatment for recurrent patellar dislocation. The purpose of this study was to report a novel suture-tie technique of patellar side fixation in medial patellofemoral ligament reconstruction for recurrent patellar dislocation, and to evaluate the intermediate-term results. We retrospectively reviewed the results of 22 MPFL reconstructions in 21 patients (6 male and 15 female) with a suture-tie technique performed by a single surgeon between March 2004 and July 2009. All patients had been diagnosed with recurrent patellar dislocation. Outcomes were assessed preoperatively and postoperatively by physical and radiographic examination as well as with Kujala and Lysholm scores. At the mean follow-up month 37.5 (range: 24 - 56 months), there was no graft failure. Primary healing was achieved in all cases. At the final follow-up, the mean Kujala score improved from 53.9 (range: 46 - 62 points) to 84.1 (range: 78 - 90 points) postoperatively (P < 0.05), and the mean Lysholm score improved from 47.2 points (range: 37 - 57 points) to 82.8 points (range: 76 - 89 points) postoperatively (P < 0.05). To date, no patients have reported redislocation or subluxation; however, there is one patient with a positive apprehension test. A suture-tie technique in medial patellofemoral ligament reconstruction can restore patella stability without significant complication.

    ABSTRACT: To investigate the diagnostic value of MRI and MR arthrography in the detection of injuries of anterior labrum in shoulder and to evaluate the accuracy of MR arthrography in the classification of anterior labrum lesion. Seventy-eight patients with arthroscopically proved anterior labrum lesions(study group) and 75 patients with arthroscopically proved intact anterior labrum (control group) from January 2007 to December 2010 were included to the study. All patients underwent MRI and MR arthrography at our institution prior to shoulder arthroscopy. All MRI and MR arthrography were analyzed by one musculoskeletal radiologists and one sports medicine surgeon who had no knowledge of the clinical histories and arthroscopic results. The same classification system of labrum lesions based on arthroscopy was used in image analysis. Imaging findings and arthroscopic findings were compared in all patients. With arthroscopy used as the standard of reference, the sensitivities, specificities and accuracies of MRI and MR arthrography in the detection of anterior labrum lesions were compared, and the sensitivities, specificities and accuracies of MR arthrography in the correct classification of anterior labrum lesions were calculated. In arthroscopy, 78 anterior labrum lesions, 67 rotator cuff lesions and 8 SLAP lesions were diagnosed, for the detection of anterior labrum lesions, the sensitivity of MRI and MR arthrography was 80.8% and 92.3%,the specificity was 89.3% and 97.3%,the accuracy was 85.0% and 94.8% respectively. Seventy-eight patients with arthroscopically proved anterior labrum lesions included 39 Bankart lesions, 32 ALPSA lesions and 7 Perthes lesions, with MR arthrography, Bankart, ALPSA, and Perthes lesions were correctly classified in 84.6%, 84.4%, and 57.1% of cases, respectively. MR arthrography has a higher sensitivity, specificity and accuracy than MRI in the detection of anterior labrum injuries. MR arthrography was useful in the classification of different variants of anterior labrum injuries before operations. It may directly influence the surgeon's strategy and is useful in preoperative planning of arthroscopic reconstructions.

    ABSTRACT: The purpose of this study was to compare the radiofrequency (RF) injury effect on cartilage in the different settings that are mostly used in clinical work under rigidly controlled laboratory conditions. Twelve fresh porcine knees were used in our study. Five treatment areas were created on the femoral condyles of each knee: the control group, coagulation (setting 2) group, coagulation (setting 7) group, ablation (setting 2) group, and ablation (setting 7) group. Hematoxylin/eosin staining, dual fluorescence staining, and the GAG content were observed to evaluate the histological cartilage changes, vacuolar cell rate of chondrocytes, depth of chondrocyte death, and detection of GAG content. Vacuolar cell rates of chondrocytes in each experimental group were higher than that in the control group (P < 0.05); there was no significant difference in vacuolar cell rate among experimental groups. Dual fluorescent staining showed that the ablation (setting 7) group had a smaller depth of cell death than did the coagulation (setting 2) group (P < 0.05); the other experimental groups showed no statistically significant difference (n.s.). In addition, there was no significant difference in GAG content between the experimental groups and control group (n.s.). The coagulation mode results in heavier thermal radiation injury to chondrocytes than does the ablation mode. Higher-power settings in the ablation mode result in lower thermal radiation injury and may be most suitable for cartilage debridement.

    ABSTRACT: To evaluate the methods and results of arthroscopy-assisted ankle arthrodesis. From January 2001 to May 2009, 25 patients with end-stage ankle joint pathology were treated with arthroscopy-assisted ankle arthrodesis. There were 18 males and 7 females with an average age of 47.5 years (ranged, 32 to 70 years). The locations were left ankle in 10 cases and right ankle in 15 cases, including 13 cases of post-traumatic osteoarthritis, 10 cases of Kaschin-Beck disease and 2 cases of rheumatoid arthritis. At pre- and post-operation, the 10-point VAS score for ankle pain was obtained; the ankle functional was evaluated by the American Orthopaedic Foot & Ankle Society ankle and hindfoot score, which include pain, activity limitations, maximum walking distance, walking surfaces, gait abnormality, sagittal motion, hindfoot motion, ankle-hind-foot stability, and alignment. All the patients were follow-up,with a mean period of 27.5 months (ranged, 20 to 35 months). All the patients were free of pain and the gait was improved. There were no complications, such as neurovascular injuries, infection or hardware failure. All the patients achieved fusion in a mean of 11.7 weeks (ranged, 8 to 15 weeks). Overall, the mean 10-point visual analog scale (VAS) score decreased from (8.60 +/- 0.96) preoperatively to (1.20 +/- 0.82) postoperatively (t=27.326, P=0.000). After operation, the items of pain, activity limitations, maximum walking distance, walking surfaces, gait abnormality, sagittal motion, hindfoot motion, ankle-hind-foot stability, and alignment improved. AOFAS score was significantly increased from (36.44 +/- 9.90) points preoperatively to (82.44 +/- 4.96) points postoperatively (t=-19.178, P=0.000). Arthroscopy-assisted ankle arthrodesis offered minimal trauma, high fusion rates, rapid recovery and low morbidity. This study confirmed the efficacy of the arthroscopy-assisted ankle arthrodesis for ankle joint pathology.

    ABSTRACT: To evaluate the efficacy of sternocleidomastoideus radiofrequency carbonation with local anesthesia under arthroscope for the treatment of congenital muscular torticollis in adults. Twenty-six cases of congenital muscular torticollis were treated by radiofrequency carbonation with local anesthesia under arthroscope. The right side was in 14 patients and left in 12. There were 11 males and 15 females with an average age of 22 years old. Sternocleidomastoideus and clavicula were pre-operatively marked. Through an artificial lacuna, arthroscope and radiofrequency probe were inserted. The mean follow-up period was 25 months (range: 15 - 71). According to the motion deficits, craniofacial asymmetry, head tilt and subjective assessment, there were 19 excellent and 7 fair outcomes. Most patients showed a marked improvement in neck motion and head tilt with satisfactory functional and cosmetic outcomes. There was no nerve or vascular injury, no recurrence, infection and scar. The overall efficacy was satisfactory. The radiofrequency therapy for torticollis with local anesthesia under arthroscopy has a satisfactory efficacy. The advantages are minimal trauma, simple procedure, less pain and better cosmetics.

    ABSTRACT: To evaluate the curative effect of RIGIDfix tibial and femur cross pin system used for hamstring grafted reconstruction of anterior cruciate ligament (ACL) in arthroscopy. Thirty two cases with ACL ruptures were reconstructed arthroscopically with hamstring grafts and the grafts fixed with RIGIDfix cross-pin on both femoral and tibial sides. They included 18 males and 14 females with a mean age of 28 (20-45) years old; the mean time from injury to operation was 3.6 (2.5-6) months. And each knee was checked by MRI and X-ray preoperatively. Through arthroscopy, we found 19 ACL ruptured from femoral attachment point, 13 from tibial point, 3 cases combined with medial meniscus injury and 4 cases with articular cartilage injury of medial femoral condyle. After semitendinosus or gracilis harvesting, the hamstring grafts were pre-tensioned and woven, the diameter of 4 or 5 strands grafts was 7-8 mm. To position and drill tibial tunnel on ACL stump of tibial crest, and to drill femoral tunnel at 10:00 to 11 o'clock of femoral intercondylar fossa transtibial with knee flexed to 90 degree, the depth of femoral tunnel was 30 mm. The RIGIDfix guide was inserted through tibial tunnel up into the femoral tunnel to drill the sleeve and interlocking Trocar across the lateral femur and keep the two sleeves fixed to the lateral femur. Insert RIGIDfix guide into the tibial tunnel, keeping the top of guide 2-3 mm beneath the endostoma of tibial tunnel, drill the sleeve and interlocking Trocar across the lateral tibia and keep the two sleeve fixed to the lateral tibia. The graft was pulled into the tunnel (the 30 mm mark on the graft should be at the edge of femoral hole) to insert the RIGIDfix cross pins from femoral tunnel to tibial tunnel, while inserting the second, third, fourth cross pin, the graft should be kept under tension. Then a knot was tied through tibial bony bridge using the Enthibond thread switched to the end of tendon grafts. We finally observed the tension of tendon grafts and the impingement of fossa intercondylic under arthroscopy. With a 16-month follow-up evaluation, all of the patients' injured knees were stable and the average Lysholm knee score increased from 62.5 to 94.5. Rulermetr device values were less than 2 mm of sagittal displacement in 28 patients and 4 mm in 4. Postoperative Lachman was negative in 30 patients and weakly positive in 2. According to the IKDC scores, 30 patients reported normal function, 2 reported nearly normal function and none reported abnormal or severely abnormal function. The grafting method of fixing both femur and tibia sides with absorbable cross pins is feasible. In this way, the graft is stabilized to allow for reconstruction. A surgeon should refrain from dissecting the tendon and enlarging the tunnel so as to promote the healing of tendon and bone.

    ABSTRACT: The fixation strength of the hamstring tendon graft on the tibial side is considered the weak point in anterior cruciate ligament (ACL) reconstruction. This work tested the hypotheses that some of these devices will resist graft slippage under loads better than others, and that some will have higher ultimate strength than others. Fourteen fresh frozen human cadaver knees underwent fixation of the hamstring tendon harvested from the knee to be used as graft material to reconstruct the ACL and were divided into two equal groups based on the fixation methods: bioabsorbable interference screw group and Intrafix group. A MTS 858 MiniBionix II testing machine was used to carry out tensile testing under an axial load parallel to the tibial tunnel with a velocity of 10 mm/min. Ultimate failure load, displacement of 100N, displacement of 400N, stiffness and mode of failure were recorded respectively. The maximum load for the Intrafix fixation group was (719.094+/-160.478) kgxmxs(-2), significantly higher than that of the bioabsorbable interference screw fixation group [(476.640+/-64.226) kgxmxs(-2), P<0.05]. The displacement levels of 100 kgxmxs(-2) and 400 kgxmxs(-2) for the Intrafix fixation group was (1.025+/-0.326) mm and (4.728+/-1.992) mm respectively, not significantly different from those of the bioabsorbable interference screw fixation [(1.335+/-0.539) mm and (7.564+/-4.307) mm respectively, t=0.2173, 0.0944, both P>0.05], and the stiffness of the Intrafix fixation group was (96.770+/-36.848) kgxm(-1)xs(-2) not significantly different from that of the bioabsorbable interference screw fixation group [(63.976+/-31.003 kgxm(-1)xs(-2)), t=0.0967, P>0.05]. After randomized t-test of significance, the displacement levels of 100N and 400N of these 2 groups were not significantly different. Both tibial site fixation with bioabsorbable interference screw and that with Intrafix in ACL reconstruction with 4-stranded hamstring tendon grafts can meet daily physiological demand. Tibial site fixation with Intrafix shows a higher failure load.
