Comparative Study Clinical Trial Controlled Clinical Trial
Comparison of two regional anesthetic techniques for knee arthroscopy.
This study compares the efficacy of "3-in-1 block" versus femoral nerve block for knee arthroscopy. One-hundred patients had a 3-in-1 block; 180 patients had a femoral nerve block. The 3-in-1 block provided anesthesia in 75 patients; 20 patients needed supplementary local anesthesia. ⋯ The 3-in-1 block provided more satisfactory muscle relaxation and a longer postoperative analgesia than femoral nerve block. No side effects were recorded in either group. Our results suggest that the 3-in-1 block is the most effective technique of regional anesthesia for knee arthroscopy.

Comparative Study
A comparison of outpatient and inpatient anterior cruciate ligament reconstruction surgery.
The feasibility of outpatient anterior cruciate ligament (ACL) surgery has not been reported in the literature. We evaluated outpatient ACL surgery by comparing outpatient versus inpatient pain control, narcotic consumption, postoperative complications, recovery time, and cost analysis. Thirty-seven ACL reconstructions were performed in 37 patients over a 16-month period. ⋯ The average inpatient cost was $9,220 (2.4 hospital days) compared with the average outpatient cost of $3,905. This reflected a savings of 58%. These results show that outpatient ACL reconstruction surgery is possible in the appropriate patient without harm to the patient and with a significant cost savings.

A 13-year-old boy with the diagnosis of osteochondritis dissecans underwent arthroscopic examination of his knee joint. At surgery a cartilaginous mass in the medial femoral condyle was identified. ⋯ Clinical and radiographic follow-up of the affected joint 5 years after surgery was satisfactory. Arthroscopic removal of an intra-articular tumor is an attractive treatment alternative, provided the lesion is accessible and there is no suggestion of a malignancy.

The neural histology of the human shoulder ligaments, glenoid labrum, and subacromial bursae were studied using a modified gold chloride stain. Two morphological types of mechanoreceptors and free nerve endings were found in the ligaments. Slow adapting Ruffini end organs and rapidly adapting Pacinian corpuscles were identified in the superior, middle, inferior, and the posterior glenohumeral ligaments. ⋯ This is the first histological evidence of neural receptors in the human shoulder ligaments, glenoid labrum, and the subacromial bursae. Any disruption of the labrum or these ligaments by trauma or surgery can deprive the shoulder of mechanical stability, and may cause a decrease in proprioception because of the loss of these afferent neural receptors. Removal of symptomatic, inflamed bursae may decrease pain signals from this area of the shoulder.
