Imaging of the postoperative meniscus is a challenge. Nevertheless, magnetic resonance imaging (MRI) of the symptomatic knee after meniscal surgery is a valuable diagnostic study of both the menisci and the entire joint. At present, symptomatic patients who have had partial meniscectomy of less than 25% may be evaluated by MRI. For those with partial meniscectomy of greater than 25% or after me...

objective: among the various impression materials, for alginate tear strength is probably more important than the compressive strength. the tear strength is important when an impression involves a mechanical undercut and/or lacks bulk strength to resist tearing. this study evaluated tear strength of iralgin and compared it with tear strength of alginoplast. methods: in this invitro experimental...

Historically meniscal cysts have been treated with either an open total menisectomy, isolated cyst excision, or a combination of the two procedures. The advent of arthroscopic techniques has led to innovative treatment options for meniscal cyst management. A review of meniscal cysts and the results of arthroscopic treatment form the basis of this study. From 1986 to 1991, 18 patients with menis...

We assessed the predictive value of the macroscopic and detailed microscopic appearance of the coracoacromial ligament, subacromial bursa and rotator-cuff tendon in 20 patients undergoing subacromial decompression for impingement in the absence of full-thickness tears of the rotator cuff. Histologically, all specimens had features of degenerative change and oedema in the extracellular matrix. I...

PURPOSE The purposes of this study were to identify the pathologic findings of sinus tarsi syndrome (STS) by subtalar arthroscopy and to evaluate the results of arthroscopic treatments in 33 consecutive cases. METHODS A retrospective review was performed in 31 consecutive patients (33 cases) who underwent subtalar arthroscopic treatment for STS. The mean follow-up duration was 24 months (rang...

Rotator cuff tears are a major cause of morbidity. Following rotator cuff tears, muscle atrophy and fatty infiltration begin in the tissue, limiting repair potential and leading to a higher re-tear rate and a worse functional outcome. We evaluated whether fatty degeneration resulting from a complete supraspinatus tear with retraction is associated with an injury to the suprascapular nerve. Four...

The study by Mall et al. is an important, clinically relevant investigation that highlights the natural history of rotator cuff disease and specifically looks at the progression of asymptomatic tears and the factors associated with this progression. While rotator cuff disease is one of the most common orthopaedic conditions, little is known about its natural history. The purposes of this study ...

introduction: scintigraphy has been considered as a useful tool in the assessment of meniscal tears. our objective was to assess the accuracy of single photon emission tomography (spect), using mri as the gold standard, in the diagnosis of meniscal tears. materials and methods: between january 2003 and february 2005, 45 patients were studied with spect and mri. results: the respective sensitivi...
