Arthroscopy is useful to detect early changes in the temporomandibular joint (TMJ). Despite great advances in arthroscopy, many arthroscopic surgeries have now been replaced by arthrocentesis. We propose a simple diagnostic and therapeutic method having operative rigid ultra-thin arthroscopy with 16 gauge needle size combined with arthrocentesis.

We applied arthroscopy in the diagnosis of thirty four patients with internal derangement of the knee from March to August, 1982. Its results were compared with clinical diagnosis and arthrographic findings. We also performed arthrofomy in twenty nine patients and the final diagnosis enabled us to evaluate the diagnostic accuracy of each method. The accuracy of clinical diagnosis was 63.4%. Arthrographic findings were correct in 77.8%. The diagnostic accuracy of arthroscopy was 92.3% with one false negative case. Unnecessary operations were avoided in five patients with the assistance of negative findings of arthroscopy. Arthrography and arthroscopy were complementary in the diagnosis of internal derangement of the knee.

Arthroscopy is recognized as an important adjunct in treatment of intra-articular fractures. The author reports on successful treatment of a displaced transverse glenoid cavity fracture, reduced and fixed with arthroscopic assist, using two cannulated screws perpendicular to the fracture surface, in a patient with frail chest. One screw passed through the Neviaser portal, and the other screw passed through the base of the coracoid process. Arthroscopy assisted reduction and 2 cannulated screw fixation through the Neviaser portal and coracoid base appears to be a good method for treatment of transverse glenoid fractures.

The hip arthroscopy develops quickly in the past 20 years. Its use in the diagnosis and treatment of the hip injury get more notably. Many of pathologic conditions previously unrecognized through X-ray, CT or MRI have been diagnosed correctly under hip arthroscopy. The technology has become gradually a golden standard to confirm the hip discords. In the present, the examining path of the hip arthroscopy contains mainly the outside path, the anterior path, the outside-posterior path. The application range of the hip arthroscopy includes the management of labral tears, the femoroacetabular impingement, the ligamentum tear injuries, the chondral lesions, the synovical abnormalities, the intra-articular infection, the loose bodies in the joint etc. The hip arthroscopy is a comprehensive technology. Its superiority can be reflect well if the doctors are familiar with the indication, the contraindication and the operation procedure. And also the thorough physical examination and imaging examination should be made before operation, as well as reasonable and effective postoperative function training should be conducted.

OBJECTIVETo conduct the anatomical study about the posterior coaxial portals via posterior tibial tendon (PTT) sheath for ankle arthroscopy.

METHODSCoaxial portals were established in 20 ankles by K-wires which were left in place for distance measurement between them and the posterior nerves, tendons and vessels. Ankle arthroscopy was performed in 5 fresh ankles using 2.7 mm 300 arthroscopy with the same portals as mentioned above. The maximum visible scope were recorded and the distance between the arthroscopy and the posterior nerves, tendons and vessels was also measured.

RESULTSThe medial portal was located 5 - 12 mm (average, 8 mm) above the tip of medial malleolus, and the lateral portal was located 8 - 24 mm (average, 15 mm) above the tip of lateral malleolus. The coaxial portals, which traversed the PTT sheath and passed posterior to the fibular, not only separated the arthroscopy and instrument from the posterior nerves, tendons and vessels by posterior capsule but also enlarged their distance. The medial and lateral malleolus articular gap, the posterior capsule could be viewed by these portals with as much as 1/2 - 2/3 posterior articular surface of talus. Not only the tibiotalar articular gap but also the dynamic movement between the mortise and the talus were clearly observed. Arthroscopic operation could be performed by instrument through the posterolateral portal.

CONCLUSIONSThe posterior coaxial portals via PTT sheath for ankle arthroscopy have such advantages as easy maneuverability, superior safety, clear vision and larger operation field under arthroscopy.

In planning treatment of tibial condylar fracture, the patient's age and physical condition, associated ligament injury and accurate fracture diagnosis, such as presence and degree of separatiori of split fragment, type of fracture and the severity of comminution must be considered. For accurate diagnosis, many kinds of methods including simple X-ray, arthroscopy, arthrography and tomography can be used. In spite of these procedures, sometimes we cannot know the accurate fracture morphology. The computed tomography(CT) has many advantages over other diagnostic methods. The application of CT in the evaluation of patients with spinal and pelvic fractures has been established, but rarely has its usefulness been noted in tibial condylar fracture. We thought that in assessing tibial condylar fracture, CT is more useful and accurate than conventional radiography. From March 1985 to August 1986, we took 17 patients(18 cases) of tibial condylar CT and were convinced with that it is a good diagnostic method. The results are as follows: l. In 5 cases, we could find a new fracture on CT film, which was impossible to be detected on simple X-ray. 2. In 7 cases, the fracture classification by plain X-rays was changed after CT check-up. 3. We could make the decision of treatment methods easily through more realistic classification and better recognition of split and comminution. 4. Proper approach could be done by understanding the accurate fracture size and localization.

In the treatment of proximal tibial condyle fracture, it should be considered that it can often accompany injuries of the collateral ligament, both cruciate ligament, and the menisci of the knee. Moreover it is necessary to restore anatomical congruity of the articular surface accurately. We performed reduction of the depressed articular fragment under monitoring of arthroscopy and fixed with cannulated cancellous screws and accompanied by bone graft under the control of image intensifier in 2 cases of Type I(Pure cleavage) and 3 cases of type II(cleavage with depression) fractures. The results were very satisfactory. Arthroscopy assisted reduction and fixation are very useful method in the treatment of proximal tibial condyle fracture because of (1) the minimized operative morbidity, (2) the ability to evaluate and manage associated intraarticular pathology simultaneously, (3) the rapid rehabilitation, (4) the achievement of good reduction comparable to open reduction.
