Arthoscopy

OBJECTIVE: Wrist arthroscopy is a challenging discipline with limited training exposure during residency. The purpose of this study was to evaluate the effectiveness of virtual knee arthroscopy simulation training for gaining proficiency in wrist arthroscopy. DESIGN: Participants were recorded performing a cadaveric wrist arthroscopy simulation. The residents then practiced knee arthroscopy on a virtual reality simulator and repeated the wrist arthroscopy simulation...

OBJECTIVES: To measure the quality of life, the time to work return, and clinical, functional, and radiographic parameters of patients treated with dorsal capsulodesis associated with scapholunate (SL) reconstruction, assisted by arthroscopy. METHODS: From January 2015 to September 2016, 14 adult patients with SL dissociation underwent surgical treatment with the SL reconstruction procedure assisted by arthroscopy, using the new technique proposed in this study...

AIM: Therapy of scapholunate advanced collapse (SLAC) wrist should be guided by the degree of arthritic changes within the radioscaphoid and midcarpal joints (stage 1-3 after Watson). Diagnostic investigations usually include X-ray imaging and wrist arthoscopy. In the present study, the interrater reliability of SLAC wrist stage classification by means of X-ray image analysis was evaluated between radiologists and hand surgeons. Ultimately, the influence of diagnostic wrist arthroscopy on the final stage classification was determined...

Traumatic dislocation of the hip is a severe injury. Even in cases of an early uncomplicated repositioning there is a high risk of associated intra-articular injuries, such as lesions of the labrum, ruptures of the ligament of the head of the femur and loose bodies. The degree of damage caused by dislocation of the hip becomes apparent with a highly increased risk of developing postinjury osteoarthritis after dislocation of the hip. Some of the major intra-articular damage resulting from hip dislocation, e...

Fourteen fit and healthy patients underwent arthroscopic subacromial decompression (ASD) of shoulder for rotator cuff impingement. Their blood chemistry was analysed pre-operatively, 24 hours post-operatively and 2-3 weeks post-operatively. Levels of haematocrit, sodium, potassium, creatinine and urea were measured. The blood chemistry returned almost to the pre-operative level at 2-3 weeks post-operatively. There was no statistically significant differences found. This study concludes that arthroscopic subacromial decompression is a safe technique when considering the blood parameters despite the haemodilution seen in all patients...

BACKGROUND: Either a nylon single suture or adhesive tape in the form of Steri strip are commonly used for the closure of portals in ankle arthroscopy. The purpose of this study was to compare the two methods with regards to their safety, complications and cosmetic result. METHODS: This was a prospective cross over study of 100 patients who underwent ankle arthroscopy. Materials used for wound closure were either a 3-0 nylon suture or a single Steri strip. Portals were reviewed according to a validated wound scoring system...

We present the results of surgical treatment of eight patients operated in the service of osteoarthritis scapho-trapézo-trapézoidienne (STT) by resection of the distal pole of the scaphoid under arthroscopic. Studies have already shown the good results of this technique in open surgery. This is a retrospective study of eight patients of mean age 70 years. They had an isolated STT osteoarthritis, which is not relieved by medical treatment. They were operated between 2004 and 2007 by the same surgeon and were reviewed at a mean of 13 months by an independent examiner...

Arthroscopy of the foot and ankle, although sometimes technically challenging, is a useful tool for the foot and ankle surgeon. Burman in 1931 was the first to attempt arthoscopy of the ankle joint and surmised that it was not a suitable joint for arthroscopy because of its narrow intra-articular space. With the development of smaller-diameter arthroscopes and improvements in joint distraction techniques, Watanabe was the first to present a series of 28 ankle arthroscopes in 1972. At present, arthroscopy is used not only to evaluate and treat intra-articular abnormalities but also for endoscopic and tendoscopic procedures...

Sports related injuries to the hip have received relatively little attention, in the part because the clinical assessment, imaging studies, and surgical techniques are less sophisticated. The evolution of hip arthroscopy has offered a less invasive technique that allows for recognition and treatment of hip pathologies that previously went unrecognized. The success of hip arthoscopy is dependent on proper patient selection based on the patient's history and diagnosis. The purpose of this clinical commentary is to outline mechanisms of injury and specific lesions that can be addresses using hip arthoscopy...

In the submitted paper the authors describe in the introduction various possible ways of using autologous, homologous and heterologous transplants. A graft taken from the patellar ligament with two bone blocks from the patella and head of the tibia is, because of the great structural strength, the transplant of choice. As far as the surgical technique is concerned, the authors abondoned the open method because of its known disadvantages such as major arthrotomy and associated damage of proprioceptors of the knee joint...

Because of their limited spatial resolution, current clinical noninvasive imaging modalities (radiography, computed tomography, conventional echography, and magnetic resonance imaging) are able to detect only the late stages of the cartilage degradation. To detect early lesions and follow their evolution in time with imaging, higher resolution is necessary. Recent work suggest that high-frequency ultrasound may serve as a useful means for the investigation of cartilage matrix structural changes occurring under various experimental and clinical circumstances, like the growing process and osteoarthritis...

Temporomandibular joint arthoscopy is a minimal invasive surgical procedure commonly used to effectively treat some internal derangement of the TMJ. However, this method is not free of complications. Arteriovenous fistula (AVF) is a lesion that communicates the high flow arterial system and the low flow venous network. We describe a new case of preauricular traumatic AVF successfully treated with external carotid embolization, along with a review of the medical literature.

Intra-operative arthroscopy and fluoroscopy provide improved visualisation and guide the restoration of intra-articular distal radial fractures while minimising the operative dissection required for their stabilisation. Radial styloid fractures, distal radial fractures with dorsal, palmar or combined ulnar-sided "die punch" fragments, palmar and dorsal Barton's fractures, and various three- and four-part intra-articular fractures without significant bone loss or defect are especially suited for this technique...

PURPOSE: Arthroscopic evaluation of the articular surface by visualization and palpation has proved to be unreliable; therefore, we investigated arthroscopically procured biopsy specimens and conventional sections by using the same histopathomorphologic techniques and compared the results for possible differences. METHODS: Cartilage biopsy specimens of 1.7 mm in diameter and conventional cartilage sections (pieces of 8 x 2 mm) were removed from the lateral femoral condyle of 53 osteoarthritis patients undergoing total knee arthroplasty...

After gaining experience in 1,000 diagnostic arthoscopies arthroscopic surgery has been performed in 300 patients between 1979 and 1982, including 100 cases of meniscectomy. A report is given on the technique, problems, complications, and early follow-up results. A select approach to endoscopic surgery has been chosen for the treatment of different meniscus lesions. A combination of motorized instruments and modified manual Gillquist technique has been applied. The legholder is of great help for arthroscopic surgery of posterior horn lesion, especially in tight knees...

Arthoscopy was performed in the upper joint compartment of 28 temporomandibular joints in 16 fresh cadavers to investigate the accuracy of arthroscopic diagnoses of perforation and adhesion. Subsequent dissections revealed that only three of nine perforations were seen arthroscopically and that three of four joints with adhesions were arthroscopically diagnosed. There was no overdiagnosis of perforation or adhesions. Intra-articular hyperplastic soft tissue formation (crab meat) was arthroscopically seen in ten joints (36%) and was with only two exceptions associated with either a perforation or adhesions...

Temporomandibular joint arthoscopy is a new diagnostic and therapeutic modality and its development is in its infancy. The purpose of this article is to describe arthroscopic pathologic findings of the superior joint space.

Diagnosis of chondral lesions as the only injury in knee trauma is difficult: Lesions of the cartilage were found by arthroscopy, months or years after trauma, in 153 patients; the diagnosis was never suspected immediately after injury. Chondral lesions may be suspected from clinical examination but never proved. Contrast arthography may reveal the injury in exceptional cases. Only arthroscopy or arthrotomy can really prove or exclude injury to the cartilage. Arthoscopy is to he preferred because of the far lower morbidity and is more reliable because of a better view of the articular surfaces...
