ABSTRACT
OBJECTIVE@#To observe the effect of electroacupuncture (EA) on the rehabilitation of knee joint function after anterior cruciate ligament (ACL) reconstruction.@*METHODS@#A total of 140 patients with ACL reconstruction were randomly divided into an observation group (58 cases recruited, 12 cases dropped out) and a control group (65 cases recruited, 5 cases dropped out). The patients in the control group were treated with routine rehabilitation treatment. The patients in the observation group, on the basis of the treatment in the control group, were treated with EA at Fengshi (GB 31), Futu (ST 32), Zusanli (ST 36), Shangjuxu (ST 37), Fenglong (ST 40), Xuanzhong (GB 39), Diji (SP 8) and Sanyinjiao (SP 6) on the affected side (2 Hz/100 Hz of dilatational wave, 2-5 mA). Each EA treatment lasted 20-30 min, twice a day for 7 days. The swelling degree (d), pain visual analogue scale (VAS), knee joint range of motion (ROM), scores of International Knee Documentation Committee (IKDC) subjective short form and scores of Lysholm were observed in the two groups 1 day, 1 month, 3 months, 6 months and 1 year after operation.@*RESULTS@#One month and 3 months after operation, the swelling degree (d) and VAS scores in the observation group were lower than those in the control group (0.05). One month, 3 months, 6 months and 1 year after operation, the ROM of the knee joint in the observation group was higher than that in the control group (<0.05), the IKDC score and Lysholm score were higher than those in the control group (<0.05). Within one year, there were no relaxations, fractures and other related complications in the two groups. The pivot shift test, anterior drawer test and the Lachman test were all negative.@*CONCLUSION@#EA combined with routine rehabilitation training could obviously reduce the pain of knee joint, improve the swelling degree, increase the ROM of knee joint, promote the functional recovery in patients with ACL reconstruction, which are superior to rehabilitation training alone.
ABSTRACT
Objective To evaluate the effectiveness of arthroscopically assisted percutaneous reduction and internal fixation with eannulated screws.Methods The fracture was reduced by closed manipulation or percutaneous leverage force by using the Kirschner wire.Then the patella was temporarily fixed by using a large size towel clamp or Kirschner wires.Under the guidance of knee arthroscopy,a micro-incision was made at the size of cannulated screw placement,the pilot holes were drilled at a proper depth,and the thread was configured.Two titanium screws were inserted parallelly.Results Following-up chekups for 4～24 months in 18 cases showed a satisfactory recovery of knee functions.According to the Bostman' standard,excellent effects were obtained in 16 cases and good effects in 2 cases.Conclusion Treatment of patellar fractures by percutaneous cannulated screw fixation under arrhroscope of- fered advantages of minimal invasion,accurate reduction,reliable fixation,and excellent recovery of joint functions.
ABSTRACT
<p><b>OBJECTIVE</b>To introduce the application of bipolar radiofrequency energy in the treatment of elongated anterior cruciate ligament (ACL) reconstruction during arthroscopy.</p><p><b>METHODS</b>From January 2002 to June 2003, 12 cases whose anterior cruciate ligament reconstruction were elongated accepted the therapy of bipolar radiofrequency energy during arthroscopy. The 12 patients included 11 men and 1 woman with an average age of 30 years ranging from 18 to 45 years old. The ACL grafts were composed of 5 patellar tendons and 7 semitendinosus tendons. The elongated reconstruction were treated by bipolar radiofrequency energy with an output of 284W. This was continued until the elongated reconstruction were tight. After the operation, the patients received unlimited orthosis and were conducted to do functional exercise of the knees. All the patients were followed up. The Lysholm-Tegner score and clinical examination of the knees were recorded and analyzed statistically with paired t text.</p><p><b>RESULTS</b>The elongated ACL reconstruction became shrinkage and tighten after treated by bipolar radiofrequency energy. The palpation by hook and Lachman test showed negative results. The follow-up time was 5-13 months, averaged 8 months. The postoperative mean Lysholm-Tegner score of the knee was 88.5, which was significantly higher than that of preoperative score of 45.5 (P < 0.01). All the patients had no postoperative complications.</p><p><b>CONCLUSION</b>By application of bipolar radiofrequency energy, the elongated ACL reconstruction can be shrunk and tightened to make the knees stabilize. The shrinkage procedure is simple, convenient and effective.</p>
