Purpose: To evaluate the results of subtalar arthroscopy and to define the indications for the procedure. Materials and Methods: Fifty-four patients were followed up for more than 1 year after subtalar arthroscopy. The mean age was 40 years, and the mean follow-up period was 18 months. Preoperative diagnoses included sinus tarsi syndrome in 19 cases, degenerative arthritis in 13 cases, calcaneal fracture in 10 cases, arthrofibrosis in 5 cases, os trigonum syndrome in 3 cases, talar fracture in 3 cases, talocalcaneal coalition in 3 cases and calcaneal tumor in 1 case. Clinically AOFAS ankle-hindfoot scale and satisfaction of the patients were evaluated. Results: There were 23 synovectomies, 13 subtalar fusions, 11 diagnostic arthroscopies, 5 adhesiolyses, 4 loose body removals, 3 excisions of os trigonum and 1 arthroscopic reduction of fracture. Twenty-five ankle arthroscopies and 11 modified Brostrom's operations were performed for the accompaning 17 ankle impingment syndromes, 11 chronic ankle instabilities and 7 osteochondral lesions of talus. AOFAS ankle-hindfoot scale was increased from 33 points preoperatively to 77 points postoperatively in subtalar fusion group, and was increased from 69 points preoperatively to 89 points postoperatively in other-than-fusion group. Ninety one percent of patients were satisfied with the procedures. There were no serious complications related to the subtalar arthroscopy. Conclusion: Subtalar arthroscopy appears to be safe and highly accurate procedure for subtalar pathology, although it requires technical expertise.

In modern society, lifestyle and individuality are important, and personalized lifestyle and patterns are emerging. The number of people with articulation diseases is increasing due to wrong living habits. In addition, as the number of households increases, there is a case where emergency care is not received at the appropriate time. We need information that can be managed by ourselves through accurate analysis according to the individual's condition for health and disease management, and care appropriate to the emergency situation. It is effectively used for classification and prediction of data using CNN in deep learning. CNN differs in accuracy and processing time according to the data features. Therefore, it is necessary to improve processing speed and accuracy for real-time healthcare. In this paper, we propose motion monitoring using Mask R-CNN for articulation disease management. The proposed method uses Mask R-CNN which is superior in accuracy and processing time than CNN. After the user's motion is learned in the neural network, if the user's motion is different from the learned data, the control method can be fed back to the user, the emergency situation can be informed to the guardian, and appropriate methods can be taken according to the situation.

Purpose: This study was done to examine the effect of an integrated care service which included a combination of oriental and western care on health outcomes in elderly patients with degenerative arthritis. Methods: A prospective comparative design was used. Data were collected from May 1, 2008 to June 30, 2009 from 85 elderly patients with degenerative arthritis in the lower extremities who were followed in a hospital out-patient department for 8 weeks. The integrated care service group (n=36) received a combination of physical therapy, acupuncture, western medicines or herbal medicines, and the western care group (n=49) received physical therapy or western medicines. Functional independence, walking speed, rotation balance, pain intensity, service satisfaction and total medical costs for the two groups were compared at 8 weeks. Results: Functional independence (t=2.14, p=.036) and walking speed (t=2.51, p=.014) improved significantly in the integrated care group while pain intensity improved significantly in the western care group (t=3.35, p=.002). The integrated care group reported higher scores for service satisfaction (t=2.09, p=.041) and higher medical costs than the western care group (t=2.15, p=.035). Conclusion: The results suggest that integrated care services are effective modalities to improve mobility and quality of life for elders with degenerative arthritis.

Human beings have made remarkable advances in medical technology as well as technological advances. However, as was the case in the past, incurable diseases still exist: temporo-mandibular joint (TMJ). The diagnosis of the Korean medical staff, currently called a "medical advance," is adhering to the outdated patient's comments, diagnosis using a doctor's auditory diagnosis and a ruler, and diagnosis of X-ray imaging. Therefore, it is important to have accurate patient symptoms, to have a doctor's own diagnosis and experience, to increase the number of diagnoses due to the severity of the symptoms, and to cover the costs of medical care. To solve this problem, the core conductive signal generated from the bridge was quantified through %MVC. Quantified EMG will be assessed and compared with Cortex to establish a jaw joint condition evaluation criterion.

Pigmented villonodular synovitis (PVNS) is a benign proliferative disorder of the synovium of joints. It occurs most commonly in the knee joint. The disease is composed of 2 different forms: diffuse and localized. The localized form is less frequent than the diffuse one. Most cases of localized PVNS involve the anterior compartment of the knee and can be usually easily diagnosed and treated with arthroscopy. We experienced a patient of localized PVNS developed on the posterior cruciate ligament, whose main symptom was persistent pain after trauma. This case occurs rarely and complete removal of the lesion was performed arthroscopically, using posterior trans-septal portal. We report this case with review of literatures.

Lathyrus palustris often used as a treatment for inflammation of the kidneys in Korean traditional medication. Generally, drugs for arthritis have anti-inflammatory and antinociceptive properties. However, the validity of the anti-inflammatory effect has not been scientifically investigated so far. Therefore, the purpose of the research was to investigate the latent anti-inflammatory ability of L. palustris using the ethanol extract. To evaluate the anti-inflammatory activities, we examined the inflammatory arbitrators such as a nitric oxide (NO) and prostaglandin E₂ (PGE₂) on RAW 264.7 cells. Our results indicated that ethanol extract significantly inhibited the lipopolysaccharide E (LPS) derived PGE₂ production in RAW 264.7 cell. The inhibitory activity of ethanol extract for PGE₂ tests with inhibition ratio showed in 40 ㎍/mL. Overall, PGE₂ tests had a higher inhibitory effect on inflammation than NO tests. This result anticipated that the ethanol extract from L. palustris is a good candidate for developing the origin of anti-inflammatory agents.

There are some methods of approach to the temporomandibular joint. The preauricular, the endaural and the postauricular incision are frequently used among those. The preauricular incision necessiates a preauricular scar, possible postopertive facial nerve damage and is the least cosmetically desirable incision. The endaural incision is more esthetic than preauricular incision, but it is not sufficient. The postauricular approach allows adequate exposure with decreased occurence of injury to facial nerve and excellent cosmetic results. The purpose of this report is to discuss the surgical approach of postauricular incision to the cases of TMJ ankyloses, internal derangement and condylar fracture of mandible.
