  • ALLOGRAFT OSTEOCHONDRAL TRANSPLANTATION WITH ARTHROSCOPIC ASSISTANCE FOR REPAIR OF OSTEOCHONDRITIS DISSECANS

    Objective To evaluate the feasibil ity and effectiveness of allograft osteochondral transplantation with arthroscopic assistance for osteochondritis dissecans (OCD) associated with large osteochondral defects. Methods From January 2004 to May 2007, 13 patients with OCD with large osteochondral defects were treated. There were 7 males and 6 females, aged 18-59 years with an average of 35.8 years. The locations were left side in 8 cases and right side in 5 cases. The disease course was 7 days to 20 years with the median duration of 42 months. Four cases had obvious sprained history. The involved locations were lateral portion of the medial femur condyle (MFC) in 5 cases, thochlea area of MFC in 2 cases and lateral femur condyle in 6 cases. The range of motion was (95.0 ± 13.5)° and the Lysholm score was 62.23 ± 7.79. According to International Cartilage Repair Society classification system and the Guhl classification of OCD under arthroscopy, all the patients were type IV. Defect areas were 3-7 cm2 with an average of 4.32 cm2. The depths of defects were 0.8-2.0 cm with an average of 1.55 cm. Allograft osteochondral transplantation combining with adsorbable screw was appl ied for the lesions. The patients were closely instructed to do exercise through following up. Results The wounds all healed by first intention Thirteen cases were followed up for 2.2 years (14 months to 4 years) after operation. Three months after operation, 2 cases had pain after continuous exercise for 1 hour, they were directed in the methods of functional exercise and to strengthen their quadriceps femoris. Medicine was given in 2 patients who had sign of friction feel ing of joint 6 months after operation. The range of motion at the last follow-up was (137.0 ± 9.8)°, showing statistically significant difference when compared with that before operation (P lt; 0.05). The X-rays and EMRI examinations at following-up indicated that bone healed well and articular facet was integrity. The Lysholm score was 92.08 ± 7.64 one year after operation, showing statistically significant difference when compared with that before operation (P lt; 0.05). Conclusion Allograft osteochondral transplantation with arthroscopic assistance is a useful method in treatment of OCD with large osteochondral defects of the knees.

  • Short-term Therapeutic Effect of Arthroscopic Microfracture Surgery Combined with Oral Glucosamine Hydrochloride on Osteochondritis Dissecans of the Knee

    ObjectiveTo assess the therapeutic effect of arthroscopic microfracture surgery combined with oral glucosamine hydrochloride on osteochondritis dissecans of the knee. MethodsBetween January 2014 and June 2015, 24 patients with osteochondritis dissecans of the knee ready to undergo arthroscopic microfracture surgery were divided into experimental group (odd surgery sequence numbers) treated with arthroscopic microfracture surgery combined with oral glucosamine hydrochloride (480 mg/time, 3 times per day, from the first day to 3 months after the surgery) and control group (even surgery sequence numbers) treated with arthroscopic microfracture surgery. All the patients were discharged from the hospital after one week of rehabilitation exercises with rehabilitation equipment of lower extremity. Follow-up lasted for at least 6 months. The therapeutic effects of the two methods were assessed according to Tegner scores for motor function of knee joint and United States New York specialty surgical hospital (HSS) scores. ResultsThe symptoms of knee joint was alleviated significantly after the operation. The function of knee joint was improved significantly after 6 weeks. Tegner and HSS scores before surgery were not significantly different between the two groups (P>0.05). The Tegner scores were not significantly different between the two groups 6 weeks after surgery (P>0.05). The difference of Tegner scores were statistically significant between the two groups 12 and 24 weeks after surgery (P<0.05), and HSS scores of the experimental group improved better than the control group 6, 12 and 24 weeks after surgery, and the differences were statistically significant (P<0.05). ConclusionThe short-term effect of arthroscopic microfracture surgery combined with oral glucosamine hydrochloride is better than that of arthroscopic microfracture surgery in the treatment of osteochondritis dissecans of the knee.
