ObjectiveTo investigate the medium-term effectiveness of both side stereo suture for meniscus bucket handle tear under arthroscopy. MethodsBetween January 2009 and December 2012, 38 patients with combined injury of meniscus bucket handle tear underwent arthroscope surgery by the method of both side stereo suture. There were 26 males and 12 females with an average age of 32 years (range, 19-42 years). The injury causes included sports injury in 21 cases, traffic accident injury in 11 cases, and other trauma in 6 cases. The left knee was involved in 15 cases and the right knee in 23 cases. The interval between injury and operation was 2 days to 6 months (mean, 2.5 months). MRI examination showed meniscus injury at grade Ⅲ, including 22 cases of internal injury and 16 cases of lateral injury. The Barrett standard, Lysholm score of knee joint, and joint mobility were used to assess the function recovery of the knee joint. ResultsAll incisions healed primarily with no complication. All cases were followed up 24.5 months on average (range, 18-36 months). Based on the Barrett standard, meniscus bucket handle tear was successfully repaired in all cases. The Lysholm scores and range of motion of the knee at 6 months, 12 months, and last follow-up were significantly better than preoperative ones (P<0.05). ConclusionThe both side stereo suture of meniscus bucket handle tear under arthroscopy has an excellent medium-term effectiveness, with the advantages of firm suture and high healing rate.
Objective To investigate the injury mechanism, clinical characteristics, and treatments of Segond fracture and complications. Methods Fifteen patients suffering from Segond fracture were treated between January 2007 and December 2011. There were 10 males and 5 females, aged 16-50 years (mean, 31.8 years). Fracture was caused by traffic accident in 8 cases, by sports in 6 cases, and by bruise in 1 case. Before operation, the knee range of motion (ROM) was (36.60 ± 8.94)°; the Lysholm score was 32.27 ± 3.73; and the International Knee Documentation Committee (IKDC) score was 42.34 ± 4.97. The duration from injury to operation was 1-3 weeks with an average of 1.2 weeks. In 12 patients having associated anterior cruciate ligament (ACL) injury, arthroscopic reconstruction of ACL was performed with allogeneic anterior tibial tendon; in 2 patients having associated avulsion fracture of the intercondylar eminence of the tibia, arthroscopic fracture reduction and fixation with Orthocord wire were performed. In 8 patients having associated meniscus injury, meniscus suture and meniscectomy were performed in 3 and 5 patients, respectively. In 7 patients having associated collateral ligament injury, conservative treatment was given in 5 patients, and medial collateral ligament was repair in 2 patients. Results All incisions healed primarily without complications of infection and nerve or blood vessel injury. All the patient were followed up 12-16 months (mean, 14.3 months). At 12 months after operation, the results of anterior drawer test, Lachman test, and lateral stress test were all negative. The knee ROM was (129.27 ± 5.89)°, the IKDC score and Lysholm score were significantly increased to 89.45 ± 3.05 and 87.87 ± 4.12 at 12 months after operation; all showing significant differences when compared with preoperative values (P lt; 0.05). Conclusion Segond fracture is often combined with ACL, collateral ligament, and meniscus injuries, and the evidence of Segond fracture can bly suggests the knee injury. Personalized treatment should be chosen according to complications.
【Abstract】 Objective To compare the short-term effects of arthroscopic partial meniscectomy in treating medial versuslateral meniscus injuries. Methods From January 2003 to January 2006, 207 patients with meniscus injury(without intraarticularligament injury) underwent arthroscopic partial meniscectomy. The medial meniscus injury group included 115 cases, 50males and 65 females; aged 14 to 78 years(mean 46.9 years); 66 left knees and 49 right knees. Twenty-six cases had injury histories,the delayed time from injury to surgery ranged from 6 d to 6 months (mean 2.1 months). The lateral meniscus injury group included92 cases, 18 males and 74 females; aged 16 to 62 years (mean 41.1 years); 57 left knees and 35 right knees. Twenty-four caseshad injury histories, the delayed time from injury to surgery ranged from 9 d to 6 months (mean 1.9 months). Lysholm score systemwas applied and the scors of pre- and post-operation and were compared between two groups. Results The period of followupranged from 12 to 45 months (mean 31.5 months). In medial meniscus injury group and lateral meniscus injury roup, theLysholm score increased from 61.3±16.9 and 57.4±17.6 preoperation to 95.0±7.9 and 93.3±7.4 postoperation respectively. Therewas statistically significant difference between preoperation and postoperation (P lt; 0.01), and there was no statistically significantdifference between two groups（P gt; 0.05）. The excellent and good rates for function of knee joint were 97.39% (excellent in 107cases, good in 5 cases and fair in 3 cases) in medial meniscus injury group and 100%(excellent in 80 cases and good in 12 cases)in lateral meniscus injury group. Conclusion Arthroscopic partial meniscectomy is a safe and effective treatment for meniscusinjury, there is no diference in short-term effects in treating medial versus lateral meniscus injuries.
Objective To summarize the characteristic manifestations in the middle and old aged people with meniscus injury and the outcome of the treatment under the arthroscope. Methods Fifty-two patients, aged 52-58 years, with meniscus injury to a total of 57 knee joints, were diagnosed and treated under the arthroscope. The history of their knee diseases was 1-21 years. Horizontal tearsoccurred in 19 knee joints, degenerative tears in 13 knee joints, complex tears in 9 knee joints, longitudinal tears in 5 knee joints, oblique tears in 4 knee joints, radial tears in 4 knee joints, and flap tears in 3 knee joints. Three meniscus tears were sutured and 54 meniscus tears were cut fully or partly under thearthroscope. Results All the postoperative patients were followed up for 6-15 months, and the average follow-up period after operation was 9 months. According to the DONG Tianxiang’s standards for the therapy under the arthroscope, the excellent result was achieved in 39 knee joints, good in 12 knee joints, and fair in 6 knee joints, with no failure. The excellent and good rate was 89.5%. Conclusion The clinical manifestations of meniscus injury are not typical in the middle and old aged people. The therapeutic effect with the help of the arthroscope is satisfactory with an advantage of minimal traumatic invasiveness to the knee joint.
Objective To investigate the clinical application of periosteal autograft in repair of cartilage defect caused by osteoarthritis of knee. Methods From 1996 to 1999, 36 knees of cartilage defect of knee joint in 28 cases were treated. In the operation, the cracked degenerative cartilage was removed before free periosteum from tibia was transplanted to repair the defect, and the meniscuses in 8 knees of the 36 knees were reconstructed. After operation, early continuous passive movement was adopted for 4 weeks, and 8 knees with reconstruction ofthe meniscus were immobilized by plaster splint for 7 days after operation and before passive movement. All of the cases were followed up for 1 to 4 years before clinical evaluation in symptoms, signs and radiological findings. Results The general satisfactory rate was 86.1%, in which the function was excellent in 22 knees and good in 9 knees. Conclusion The periosteal autograft is a good choice for repairing cartilage defect due to osteoarthritis, with a satisfactory outcomein the short term.
