Most arthroscopic approaches allow for inspection of the lateral part of the hip joint, but visualization of the medial part is difficult. This article describes the removal of a bullet lodged in the right femoral head of a 33-year-old man. By using an inferomedial arthroscopic approach, we avoided a formal arthrotomy and the disadvantages of other arthroscopic approaches, which include the need for alternate portals, the need for traction, and the risk of both articular cartilage and acetabular labrum damage. The authors believe that this case demonstrates the effective use of the inferomedial arthroscopic approach as an alternative method for removing foreign bodies.

Comparative Study
Thermometric determination of cartilage matrix temperatures during thermal chondroplasty: comparison of bipolar and monopolar radiofrequency devices.
To compare cartilage matrix temperatures between monopolar radiofrequency energy (mRFE) and bipolar RFE (bRFE) at 3 depths under the articular surface during thermal chondroplasty. We hypothesized that cartilage temperatures would be higher at all cartilage depths for the bRFE device than for the mRFE device. ⋯ In this study, we found significant differences between bRFE and a temperature-controlled mRFE device with regard to depth of thermal heating of cartilage in vitro. Bipolar RFE resulted in matrix temperatures high enough (>70 degrees C) to kill cells as deep as 2,000 microm under the articular surface. Fluid flow during thermal chondroplasty had the effect of significantly increasing cartilage matrix temperatures at 200 and 500 microm with the mRFE device. During thermal chondroplasty, bRFE creates greater matrix temperature elevations at equivalent depths and treatment duration than does mRFE. Excessive temperatures generated deep within the cartilage matrix could cause full-thickness chondrocyte death, in vivo.

Bilateral endoscopic carpal tunnel releases: Simultaneous versus staged operative intervention.
Open and endoscopic carpal tunnel release techniques have achieved excellent results for treatment of carpal tunnel syndrome. Symptoms frequently occur bilaterally but there are no reports of simultaneous operative intervention. The purpose of this study was to evaluate results in patients who underwent staged bilateral endoscopic carpal tunnel releases and in those who underwent simultaneous bilateral releases. ⋯ Simultaneous bilateral endoscopic carpal tunnel releases are well tolerated with mild restrictions and a decrease in cost.

We report an unusual use of the arthroscope in the case of a man who accidentally shot himself through his left thigh, the bullet ending up in the ipsilateral knee joint. After radiographic diagnosis, the bullet was successfully removed through a standard arthroscopic procedure. The patient had a quick and complete recovery. Review of the literature and the 4 steps of successful management of gunshot wounds are included.

We review the literature on complication of arthroscopic shoulder surgery and their management. Computer data based searches were used to identify articles regarding complications of shoulder arthroscopy, as well as hand searches of Arthroscopy and Journal of Shoulder and Elbow Surgery over the last decade. Arthroscopic shoulder surgery has become a popular therapeutic and diagnostic procedure during the past two decades. ⋯ While the rate of complications especially with newer procedures remain elusive, most studies suggest that the rate is low, 5.8-9.5% in all recent review studies published. Underreporting complications makes assessment of incidence rates of complication difficult. Proper patient selection, attention to operative detail, and careful post-operative monitoring can minimize the morbidity associated with these complications.
