  • There has been a controversy about the effectiveness of the synovectomy of the knee in the rheumatoid arthritis. So we studied to determine if the arthroscopic synovectomy of the knee was of benefit in the rheumatoid arthritis. We ana lysed 25 knees of 15 patients who underwent the arthroscopic synovectomy of the knee joint for their rheumatoid arthritis from Jun. 1995 to Oct. 1996. The average follow-up period was 20.1 months($12\~28$ months). The results were as follows; 1. Satisfactory results were obtained in 20 knees $(80\%)$ for the pain and the effusion each, 23 $(92\%)$ for the range of motion and 19 $(76\%)$ for the functional capacity. 2. In the overall results for the pain. effusion. range of motion and the functional capacity. we obtained excellent results in 14 knees $(56\%)$ and satisfactory results in 9 knees $(32\%)$. 3. In the patient's self assessment, 11 patients $(44\%)$ were delighted and 10 patients $(40\%)$ were satisfactory. 4. In the overall results according to the articular cartilage damage, satisfactory results were obtained in 15 $(93\%)$ out of 16 knees in Grade I and II, and 6 $(75\%)$ out of 8 knees in Grade III and IV. In conclusion, arthroscopic synovectomy could be one of very useful treatments for the rheumatoid knee. But further study is needed to get the long-term results of the synovectomy because there's many reports saying gradual decrease of good results with increasing time. And continuous and proper medical treatment including DMARDs, is needed to effectively control the rheumatoid arthritis even after the synovectomy.

  • Purpose: Stiffness in the first metatarsophalangeal joint after surgery for hallux valgus has been reported. The goal of this study was to test the efficacy of releasing plantar aponeurosis for improving the range of extension in the first metatarsophalangeal joint that was limited after hallux valgus surgery. Materials and Methods: Thirteen patients (1 man, 12 women [17 feet]; median age, 54.4 years; range, 44~69 years) with limited first metatarsophalangeal joint extension after hallux valgus surgery, who underwent an additional procedure of plantar aponeurosis release between March 2015 and August 2015, were included. Subsequently, the passive range of extension in the first metatarsophalangeal joint was evaluated via knee extension and flexion positions. Hallux valgus angle, inter-metatarsal angle, distal metatarsal articular angle, and talo-first metatarsal angle were measured on weightbearing dorsoplantar and lateral radiographs of the foot preoperatively. Results: The mean range of extension for the first metatarsophalangeal joint improved significantly, from $2.5^{\circ}$ to $40.9^{\circ}$ in the knee extension position (p<0.00). The mean extension range for the first metatarsophalangeal joint also improved, from $18.2^{\circ}$ to $43.2^{\circ}$ in the knee flexion position (p<0.00). In all patients, congruence of the first metatarsophalangeal joint was recovered. Conclusion: Plantar aponeurosis release is an effective additional procedure for improving the extension range of the first metatarsophalangeal joint after hallux valgus surgery.

  • A new method of limb sparing by resection, extracorporeal irradiation and reimplantation has several theoretical advantages. This method preserves the mobility of a joint and avoids the problem of loosening or breakage of tumor prosthesis. This study involved using extracorporeal irradiated autogenous joint transplantation for reconstruction after en bloc resection, and observed the periods of functional union and histological changes in irradiated tissue of the knee joint. This study also aimed to clarify whether the degeneration of articular cartilage is induced in rabbits by a single 50Gy dose of irradiation at the knee joint. Twenty New Zealand rabbits about three kilograms were randomized into two groups of 10 rabbits each. In group 1, as control, we resected the knee joint followed by reimplantation without irradiation. Group 2 received extracorporeal irradiation on the resected knee joint followed by reimplantation. Following are the results of these observations. The osteotomy site showed external callus formation in the roentgenographic finding eight weeks after reimplantation. There was marked degenerative changes in the collagen fiber of the irradiated anterior cruciate ligament and meniscus during the fourth week, but new blood-vessel formation was observed in the vicinity. There was degenerative changes in the collagen fiber of articular cartilage treated extracorporeal irradiation at four and eight weeks in the scanning electron micrographic findings. These findings was in contrast to those of subchondral bone which showed decreased cellularity and empty lacuna at four and eight weeks. Autoradiography demonstrated active [$^3H$]uridine incorporation by irradiated chondrocyte at eight weeks after reimplantation. These results indicate that when destruction of the articular cartilage and soft tissue of the knee joint is not severe, extracorporeal irradiation and reimplantation can be used with several advantage in maintaining movement of the joint while avoiding problems of tumor prosthesis and rejection, and therefore extracorporeal irradiated autogenous joint transplantation can be used as a limb-sparing procedure for temporary biological spacer in the childhood bone tumor around the knee.

  • Purpose: The lower leg often has poor vascularity, proximity to bone, and insufficient soft tissue. The island flaps offer a feasible one stage reconstruction and has a remarkable vascularization and high quality results for soft tissue defect with or without bony problems to occur on regions below the knee. So we reported our experience of island flaps with review of the literatures. Methods: We reconstructed 29 cases of soft tissue and 2 cases of bony defect on regions below the knee by using various island flaps at our hospital from December, 1991 to January, 2006. We used 2 fibular osteocutaneous island flaps, 15 reverse sural island flaps, 6 extensor digitorum brevis muscular island flaps, 2 medial plantar island flaps, 5 saphenous island flaps, and a dorsalis pedis island flap. Results: Partial necrosis was developed in 4 out of 15 reverse sural island flaps and 1 out of 5 saphenous island flaps, but they were healed with secondary skin graft. There was partial loss of skin graft on the donor sites in 2 cases. Conclusion: Island flaps are very useful for reconstruction of regions below the knee because island flaps have good vascularity and less risk of infection. Generous flap size, easy operative technique, lower cost, shorter operative time, and minimal morbidity at the donor site are other advantages. We attained satisfactory results.

  • Purpose: This study aimed to investigate the effect of robot-assisted gait training on the active ranges of motion, gait abilities, and biomechanical characteristics of gait in patients who underwent lower extremity surgery, and to verify the effectiveness and clinical usefulness of robot-assisted gait training. Methods: This study was conducted on 14 subjects who underwent lower extremity surgery. The subjects participated in robot-assisted gait training for 2 weeks. The active ranges of motion of the lower extremities were evaluated, and gait abilities were assessed using 10-m and 2-min walk tests. An STT Systems Inertial Measurement Unit was used to collect data on biomechanical characteristics during gait. Spatiotemporal parameters were used to measure cadence, step length, and velocity, and kinematic parameters were used to measure hip and knee joint movement during gait. Results: Significant improvements in the active ranges of motion of the hip and knee joints (flexion, extension, abduction, and adduction) and in the 10-m and 2-min walk test results were observed after robot-assisted gait training (p < 0.05). In addition, biomechanical characteristics of gait, spatiotemporal factors (cadence, step length, and velocity), and kinematic factors (gait hip flexion-extension, internal rotation-external rotation angle, and knee joint flexion-extension) were also significantly improved (p < 0.05). Conclusion: The results of this study are of clinical importance as they demonstrate that robot-assisted gait training can be used as an effective intervention method for patients who have undergone lower extremity surgery. Furthermore, the findings of this study are clinically meaningful as they expand the scope of robot-assisted gait training, which is currently mainly applied to patients with central nervous system conditions.

  • Radiofrequency neurolysis (RFN) of the genicular nerves has recently become accepted as an effective technique to alleviate knee pain particularly in patients with knee osteoarthritis (OA) or postoperative pain. However, genicular nerve RFN can produce high procedure and equipment costs, longer procedural times, procedure-related pain, and failure rate of over 25%. We are presenting two cases of alcohol neurolysis of the genicular nerve using fluoroscopy and ultrasonography in patients with knee OA or persistent postsurgical pain of the knee. Alcohol neurolysis of the genicular nerve with dual imaging modality can be a cheap, safe and effective method in patients with chronic knee pain.
