ObjectiveTo investigate the effectiveness of partial anterior cruciate ligament (ACL) suture repair with wide awake local anesthesia no tourniquet (WALANT) technique.MethodsBetween July 2017 and July 2019, 18 patients with partial ACL injury were admitted. There were 10 males and 8 females, with an average age of 40.5 years (range, 22-57 years). There were 5 cases on the left knee and 13 cases on the right knee. Forteen cases had a clear history of trauma or sports injury, and 4 cases had no obvious cause. The time from injury to operation was 1-6 months (median, 3 months). Partial ligament was sutured using WALANT technique under arthroscopy. The operation time, total hospital stay, and postoperative hospital stay were recorded. Lachman test and anterior drawer test were performed to evaluate the knee joint stability after treatment, and Lysholm and International Knee Documentation Committee (IKDC) scores were used to evaluate the knee function. Five-point Likert scaling were used to evaluate postoperative patient satisfaction.ResultsThe operation time was 30-100 minutes (mean, 64.2 minutes). The total hospital stay was 2-12 days (mean, 4.5 days). Postoperative hospital stay was 1-4 days (mean, 1.8 days). All incisions healed by first intention after operation, and no surgery-related complications occurred. All patients were followed up 12-36 months (mean, 19.1 months). Lachman test and anterior drawer test were negative after operation. Lysholm score and IKDC score at 6 and 12 months after operation were significantly higher than those before operation, and at 12 months after operation were higher than those at 6 months after operation, the differences were significant (P<0.05). At last follow-up, according to five-point Likert scaling of patient satisfaction, 7 cases were very satisfied, 10 cases were relatively satisfied, and 1 case was general. The total patient satisfaction rate was 94.4% (17/18). MRI scan showed the good ligament tension.ConclusionUsing WALANT technique to repair partial ACL injuries under arthroscopy can retain the patient’s own ligament tissue to the maximum extent and achieve satisfactory short-term effectiveness.
Objective To evaluate the effectiveness of arthroscopic treatment and nonsurgical treatment on ankle degenerative osteoarthropathy. Methods Between July 2009 and June 2011, 58 patients (58 ankles) suffering from ankle degenerative osteoarthropathy underwent arthroscopic treatment (arthroscopic group, n=28) and routine treatment (control group, n=30). There was no significant difference in gender, age, body mass index, disease duration, and degree of ankle degenerative osteoarthropathy between 2 groups (P gt; 0.05). Mazur score, visual analogue scale (VAS), and Tegner activity scale were used to evaluate the effectiveness. Results Incision healed primarily in arthroscopic group. The patients of 2 groups were followed up 1-2 years, averaged 1.5 years in arthroscopic group and 1.6 years in control group. At last follow-up, Mazur, VAS, and Tegner scores were significantly improved when compared with the preoperative scores in 2 groups (P lt; 0.05), but no significant difference was found at last follow-up between 2 groups (P gt; 0.05). According to Mazur scoring, the results were excellent in 8 cases, good in 14 cases, fair in 5 cases, and poor in 1 case, with an excellent and good rate of 79% in arthroscopic group; the results were excellent in 6 cases, good in 15 cases, fair in 6 cases, and poor in 3 cases, with an excellent and good rate of 70% in control group; and no significant difference was observed between 2 groups (u=0.98, P=0.77). Moreover, there was no correlation between Outerbridge classification and Mazur score in patients undergoing arthroscopic treatment (r=0.18, P=0.34). Conclusion Arthroscopic and nonsurgical treatments of ankle degenerative osteoarthropathy can both achieve good effectiveness.
Objective To investigate the effectiveness of anterior cruciate ligament (ACL) reconstruction for single bundle rupture using hamstring autograft with preservation of the left bundle. Methods Between March 2005 and May 2009, 20 patientswith ACL single bundle rupture were treated using hamstring autograft with preservation of the left bundle. There were 15 males and 5 females with an average age of 25.5 years (range, 16-43 years). Injury was caused by sports in all the patients. The locations were the left knee in 12 cases and the right knee in 8 cases, including 11 cases of antero-medial bundle rupture and 9 cases of postero-lateral bundle rupture. Ten patients had positive results of anterior drawer test, 8 patients had positive result of Lachman test, and 2 patients had positive results of both tests. The Lysholm score was 67.0 ± 6.2 and International Knee Documentation Committee (IKDC) score was 69.0 ± 7.5. The time from injury to surgery was 1 week to 12 months (mean, 2.8 months). Results All the patients had healing of incision by first intention. Twenty patients were followed up 18.5 months on average (range, 12-36 months). The range of motion of all the knees was more than 130° at last follow-up. The results of both the anterior drawer test and Lachman test were negative in 17patients. The result of anterior drawer test was weakly positive and the result of Lachman test was negative in 2 patients. The result of Lachman test was weakly positive and the result of the anterior drawer test was negative in 1 patient. The Lysholm score and the IKDC score were 91.0 ± 3.7 and 92.0 ± 4.9 at last follow-up, showing significant differences when compared with the preoperative ones (P lt; 0.05). Conclusion ACL reconstruction using hamstring autograft with preservation of the left bundle has satisfactory effects and can partially preserve the proprioceptive sense of the knee, which is beneficial for improving the stability of the knee.
Objective To investigate the outcomes of arthroscopic reduction and internal fixation of tibial eminence avulsion fracture using absorbable double suture anchors. Methods Between February 2007 and August 2009, 18 patients with tibial eminence avulsion fracture were treated with arthroscopic reduction and fixation using absorbable doublensuture anchors. There were 12 males and 6 females with an average age of 30.6 years (range, 17-48 years). The disease causes were traffic accident injury in 4 cases, sport injury in 8 cases, and fall ing from height injury in 6 cases; the locations were left side in 7 cases and right side in 11 cases. The results of the anterior drawer test and Lachman test were positive. According to Meyers-McKeever classification, 10 cases were rated as type II, 7 as type III, and 1 as type IV fractures. The time from injury to treatment was 6-20 days (mean, 10.2 days). Results Incision healed primarily. All the patients were followed up 29.1 months (range, 13-43 months). The X-ray films showed good reduction of fracture immediately after operation and fracture heal ing at 3 months. At the last follow-up, the range of motion of knee was 0-130°. The results of Lachman test and anterior drawer test were negative in 18 cases and 16 cases, repectively; and the results of anterior drawer test were weakly positive in 2 cases. The mean Lysholm score was significantly improved from 53.9 ± 6.7 preoperatively to 91.6 ± 4.2 postoperatively (t=22.100, P=0.000). The Inter national knee Documentation Commitee (IKDC) 2000 subject score improved from 58.1 ± 3.7 preoperatively to 92.8 ± 5.9 postoperatively (t=20.700, P=0.000). Conclusion Arthroscopic treatment using absorbable double suture anchors for tibial eminence avulsion fracture can provide satisfactory reduction, stable fixation, and good heal ing of the avulsed fragment, which is a minimally-invasive, simple, and effective treatment for patients with tibial eminence avulsion fracture.
Objective To investigate the effectiveness of percutaneous reduction by leverage and fixation using nonabsorbable suture with neckwear knot loop l igature to treat tibial intercondylar eminence avulsion fractures under the arthroscope. Methods Between February 2003 and December 2008, 28 patients with tibial intercondylar eminence avulsion fractures were treated, including 16 left knees and 12 right knees. There were 15 males and 13 females with an average age of19.5 years (range, 14-45 years). The injury causes included traffic accident injury in 11 cases, sport injury in 10 cases, and sprain injury in 7 cases. Based on Meyers-McKeever classification, there were 18 cases of type III and 10 cases of type IV. The X-ray films showed the tibial intercondylar eminence displaced fracture. The mean time between trauma and operation was 7 days (range, 4-12 days). All patients were treated surgically with an arthroscopically assisted reduction by leverage and fixation using 5-0 Ethibond suture with neckwear knot loop l igature. Results All incisions healed by first intention without infection or injuries of nerves and vessels. Twenty-eight patients were followed up 26 months on average (range, 12-66 months). The X-ray films showed fracture heal ing within 9-13 weeks (mean, 11 weeks). At last follow-up, all patients were able to return to their pre-injury activity and daily l ife. The knee joint was stable with no l imp or impingement of intercondylar fossa. The knee joint range of motion was 0-130°. The results of Lachman and anterior drawer tests were negative in all patients. At last follow-up, the Lysholm score was 93.5 ± 2.5, showing significant difference when compared with the preoperative one (29.0±2.2, t=53.000, P=0.000). Conclusion Percutaneous reduction by leverage and fixation using nonabsorbable suture with neckwear knot loop l igature is minimally invasive and satisfied reduction and fixation in treating the tibial intercondylar eminence avulsion fracture under the arthroscope, so it is benefit for early functional exercises, and can achieve excellent results.
Objective To assess the therapeutic effect of sulodexide for diabetic patients with early nephropathy. Methods A total of 60 patients with early diabetic nephropathy (albuminuria: 30 to 300 mg/24 h, male/female: 30/30, mean age: 51.23 years, mean course of disease: 12.9 years) were randomized equally into three groups: the routine treatment group, cozaar group (50 mg qd, po for 12 weeks) and sulodexid group (600 LSU qd, iv or im for 4 weeks, 250 LSU bid, po for 8 weeks). The levels of urinary albumin excretion rate (UAER), urea nitrogen and creatinine were determined. Results After three months of treatment, the level of UAER was decreased significantly in both the sulodexide group and cozaar group (Plt;0.01), but not in the routine treatment group (Pgt;0.05). The level of UAER was reduced by 34.04% and 33.62% in the cozaar group and the sulodexide group, respectively. Significant difference was noted in the level of UAER between the cozaar/sulodexide groups and the routine treatment group (Plt;0.01), but no significant difference was observed between cozaar group and sulodexide group (Pgt;0.05). Conclusion Sulodexide could decrease the level of UAER in patients with early diabetic nephropathy. It has similar efficacy to cozaar.
ObjectiveTo assess the mid-term effectiveness of anterior cruciate ligament (ACL) revision and to analyze the relevant factors that may affect the surgical outcomes.MethodsThe clinical data of 24 patients who underwent ACL revision surgery between April 2009 and July 2018 and were followed up for more than 2 years were retrospectively analyzed. There were 20 males and 4 females with a median age of 30 years [interquartile distance (IQR) was (25, 36) years]. The median body mass index was 24.45 kg/m2 and IQR was (22.93, 25.93) kg/m2. The median time between ACL revision and reconstruction was 41 months and IQR was (15, 85) months. The direct cause of the failure of reconstruction surgery included 14 cases of trauma, 8 cases of no obvious cause, and 2 cases of infection. During the revision operation, 14 patients had a poor bone tunnel position, all of which were drilled with new tunnels, the remaining 10 patients were freshly modified on the basis of the original bone tunnel. Seventeen patients used autogenous tendon revision, 7 patients used LARS ligament; 16 patients had cartilage injury. The Lysholm score, the International Knee Documentation Committee (IKDC) score, and the Tegner sports rating score were used for functional evaluation before operation, at 1 year after operation, and at last follow-up. The Likert satisfaction score was recorded at last follow-up.ResultsPatients were followed up with a median time of 47 months and IQR was (32, 61) months. The Lysholm score, IKDC score, and Tegner sports rating score were significantly improved at 1 year after operation and at last follow-up when compared with preoperative scores (P<0.05). There was no significant difference between at last follow-up and at 1 year after operation (P>0.05). At last follow-up, the median Likert satisfaction score was 4.0 and IQR was (3.0, 4.5). According to the presence or absence of cartilage damage and the type of graft, the above scores at last follow-up were compared between the groups, and the differences were not significant (P>0.05). At last follow-up, 2 patients had graft fractures due to trauma again, and autogenous iliac bones were taken to fill the bone tunnel, and the second stage was revised; the rest of the patients recovered satisfactorily.ConclusionWith preoperative identification of the cause of ACL reconstruction failure, the stability and function of knee joint can be significantly improved by selecting appropriate bone tunnels and grafts during the revision and by active rehabilitation exercises.
