A unique case is described involving the arthroscopic removal of a bullet in the wall of the acetabulum from a low-velocity gunshot wound. The projectile entered the abdomen anteriorly and penetrated the urinary bladder and the inner wall of the acetabulum before becoming embedded intra-articularly in the subchondral bone of the hip joint. ⋯ No complications were encountered. Arthroscopy allowed adequate inspection of the articular surface, irrigation of the joint, and removal of the foreign body while avoiding an invasive arthrotomy with its associated morbidity and soft tissue disruption.

Many studies in orthopaedics and sports medicine have not considered sample size or statistical power as important issues in study design. This article addresses the importance of a sample size calculation in randomized clinical trials and the components of the calculations that researchers must consider in their preliminary planning of an investigation. The types of data being collected, level of significance, types I and II errors, and power are also addressed.

Randomized Controlled Trial Comparative Study Clinical Trial
Evaluation of postoperative bupivacaine infusion for pain management after anterior cruciate ligament reconstruction.
Postoperative pain control has received increasing attention by health care providers in the new millennium. In fact, pain was called the "sixth vital sign" by the Joint Commission on Accreditation of Healthcare Organizations (JCAHO) in 2001. The continued challenge of effective, safe analgesia in the outpatient setting has promoted the use of various devices designed to deliver local anesthetic directly to the surgical site. We endeavored to evaluate the efficacy of one such device currently in use. ⋯ The data suggest some element of placebo benefit at median pain ratings but a protective effect of the bupivacaine at maximum pain levels.

Randomized Controlled Trial Clinical Trial
Accelerated rehabilitation after arthroscopic Bankart repair for selected cases: a prospective randomized clinical study.
Increased stress within a certain limit enhances ligament healing and improves joint function. In this prospective randomized clinical trial, we compared the clinical results of early motion versus conventional immobilization after arthroscopic Bankart repair in a selected patient population. ⋯ Early mobilization of the operated shoulder after arthroscopic Bankart repair does not increase the recurrence rate in a selected group of patients. Although the final outcomes are approximately the same for both groups, the accelerated rehabilitation program promotes functional recovery and reduces postoperative pain, which allows patients an early return to desired activities.

The purpose of this study was to evaluate the frequency and precise pathology of articular cartilage injuries after acute patellar dislocation. ⋯ From this study, articular cartilage injuries, especially of the patella, seem to be common occurrences after acute patellar dislocation. Chondral and osteochondral injuries of the patella were classified into 3 groups.
