OBJECTIVE: Bipolar radiofrequency (bRF) ablation is gaining popularity as a treatment modality for unstable knee chondral lesions of the knee. Limited reports of osteonecrosis and chondrolysis have been published; however, there is little data examining the safety of this treatment in larger series. This study aims to evaluate the safety and efficacy of bRF in the treatment of chondral lesions encountered during knee arthroscopy. DESIGN: A retrospective evaluation of adverse outcomes in patients that underwent treatment of chondral lesions using bRF was undertaken...

BACKGROUND: Synovial membrane inflammation is the most common finding presenting during hip arthroscopy, and may play a role in hip pain. We sought to determine the relationships between synovial cytokine levels, hip pain, and arthroscopic findings of the hip joint. METHODS: We prospectively included 33 patients who underwent arthroscopic hip surgery (34 hips). For all patients, radiographs and severity of pain were evaluated preoperatively. During arthroscopy, we classified the chondral injury and synovitis, noted the incidence of labral tear and its instability, and a sample of the synovial membrane was harvested for quantitative PCR to determine levels of TNFα, IL1β, IL6, ADAMTS4, MMP1, and MMP3...

Background Besides the known intraarticular femoroacetabular impingement (FAI), recently forms of extra-articular impingement of the hip have been increasingly recognized. Recent studies have described an extra-articular impingement between a distal extension of the anterior inferior iliac spine (AIIS) and the femoral neck (AIIS or subspine impingement). Evidently, an association between this subspine impingement and an intraarticular FAI seems to exist. Little is known about the incidence of this impingement type and the value of its radiological diagnostics...

OBJECTIVES: Hip arthroscopy utilization has significantly increased in recent years. While it is a relatively safe procedure, it is not without risk. Life-threatening complications, albeit rare, can potentially occur and must be appropriately recognized and treated. We describe 2 cases in which patients' undergoing hip arthroscopy developed pulmonary edema and their respective courses of treatment. METHODS: Both patients were being treated for symptomatic femoroacetabular impingement (FAI), with labral tears, requiring operative management after a failed trial of conservative management...

BACKGROUND: Postoperative pain is a common, distressing symptom following arthroscopic knee surgery. The aim of this study was to compare the potential analgesic effect of dexmedetomidine after intrathecal versus intra-articular administration following arthroscopic knee surgery. METHODS: Ninety patients undergoing unilateral elective arthroscopic knee surgery were randomly assigned into three groups in a double-blind placebo controlled study. The intrathecal dexmedetomidine group (IT) received an intrathecal block with intrathecal dexmedetomidine, the intra-articular group (IA) received an intrathecal block and intra-articular dexmedetomidine, and the control group received an intrathecal block and intra-articular saline...

Minor instability of the shoulder has recently drawn attention as a cause of shoulder pain in athletes. However, it is difficult to correctly diagnose the direction in which the humeral head translates and subluxates, and to clarify the pathology of the instability. We present a case of a 20-year-old male with an unstable shoulder who could not raise his left arm due to pain. Since 6 years prior to the onset of pain, the patient could asymptomatically perform voluntary subluxation, but it was slight and the direction of the subluxation could not be confirmed...

Anterior arthroscopic tibiotalar arthrodesis has been well codified. A posterior approach with the patient in prone position is indicated when the anterior approach is precluded by soft tissue issues or for a 1-step procedure associated with posterior subtalar fusion. In an anatomic study, we assessed the feasibility of posterior arthroscopic tibiotalar fusion and sought to determine the arthroscopy entry points, mortise cartilage freshening quality, and risk of osseous, tendinous, vascular, and neural complications...

Snapping scapula syndrome has several etiologies, including subscapular osteochondroma. When this tumor needs to be removed, this can be done arthroscopically, a procedure that has restricted indications. The authors present a case of a patient with superomedial subscapular osteochondroma who underwent a scapulothoracic arthroscopy for its removal.

Therapeutic arthroscopy with microfracture leads to fibrocartilaginous repair and is an effective treatment of osteochondral lesions of the talus. A full diagnostic arthroscopy is performed, and then attention is turned to the osteochondral defect. We describe in detail patient positioning, ankle distraction, portal placement, steps of the diagnostic arthroscopy, and the technique of microfracture. We then discuss the special considerations to be taken regarding the use of a distractor, protection of neurovascular structures, and the indications for microfracture...
