Comparative Study
Injury to the infrapatellar branch of the saphenous nerve in ACL reconstruction with the hamstrings technique: clinical and electrophysiological study.
The incidence of IBSN injury to the infrapatellar branch of the saphenous nerve (IBSN) in ACL surgery using the hamstrings technique has been reported to be between 30 and 59%. The purpose of this study was to evaluate the incidence of IBSN injury in ACL surgery with the hamstrings technique through clinical and electrophysiological evaluation, and also to evaluate potential risk factors of IBSN injury related to the surgical incision. Between November 2003-September 2004, 21 consecutive patients (22 knees) with an acute ACL rupture suitable for reconstruction were included. ⋯ The presence of sensory loss associated with damage to the IBSN did not correlate with the size of the incision or the distance to the tibial tubercle. This injury probably occurs during tendon harvesting as found by an injury to the saphenous nerve in two of our patients. However the sensory loss does not impair normal daily activities in these patients.

Comparative Study
Prospective follow-up of a simple arthroscopic-assisted technique for lateral tibial plateau fractures: results at 5 years.
This study reports the 5-year clinical and radiological outcomes of a simple arthroscopic-assisted technique for Schatzker types II and III tibial plateau fractures, without bone grafting. Forty six patients (46% males, 54% females, average age 48 years, SD 13.6 years), with tibial plateau fractures Schatzker types II (41%) and III (59%), underwent an arthroscopic-assisted technique conceived to use a compacted cancellous bone graft, taken from the medial metaphyseal side of the tibia, and a percutaneous fixation. The patients were prospectively followed-up at 1, 3 and 5 years from surgery. ⋯ The radiological Rasmussen score was excellent in five patients (11%), good in 39 (85%) and fair in two (4%). In the weight-bearing radiographs a valgus deviation was present in four patients (8.7%). This technique has outcomes encouraging and comparable to the results of other techniques that use either iliac crest graft or bone substitutes.

Comparative Study
Pain and affective distress before and after ACL surgery: a comparison of amateur and professional male soccer players in the early postoperative period.
Pain thresholds and levels of distress before and in the early postoperative period after anterior cruciate ligament surgery were measured in professional and amateur male soccer players and compared. Between June 2005 and March 2007, 30 soccer players (10 amateur, 20 professional) with acute or chronic tears of the anterior cruciate ligament who were scheduled for a bone-tendon-bone ACL reconstruction procedure were enrolled in the study. Measures of pain intensity, depression and anxiety were assessed 1 day pre-operation and 1 week and 3 weeks post-operation (T1 T2 and T3). ⋯ High depression scores did not correlate with high pain scores. Pain scores between professional and amateur soccer players with ACL injuries were not significantly different pre-op or in the early post-op period. Depression was more common in professionals before and after their ACL surgery, but anxiety levels were not significantly different between the two groups.
