ACL Tears (Subscribe)  

The kNEEguru website presents a new course by Dr Frank Noyes on the reasons for ACL graft failure and the pitfalls of reconstruction surgery. Aimed at the consumer, but at a good level for family practitioners, the rehabilitation team, nurses and medical students.  [Free]

There are no controlled, prospective studies comparing the 10-year outcomes of anterior cruciate ligament (ACL) reconstruction using patellar tendon (PT) and 4-strand hamstring tendon (HT) autografts.
Hypothesis: Comparable results are possible with HT and PT autografts.
Conclusions: It is possible to obtain excellent results with both HT and PT autografts. We recommend HT...

Multiple techniques are available for reconstruction of the anterior cruciate ligament (ACL). Controversy certainly exists as to which autograft is best and which methods of placement and fixation should be used. Instances exist in which autograft is not available due to multiple reconstructions or in combined ligament injuries. In addition, after...

Tears of the ACL, once thought to be career ending injuries, are no longer associated with dire outcomes. Early and accurate detection of the pathology; minimally invasive surgical reconstruction; and focused rehabilitation protocols have all contributed to the excellent functional results that are now commonly attained. Nonetheless, even with optimal...

The anterior cruciate ligament (ACL) originates from the tibial plateau just medial and anterior to the tibial eminence. The ACL tracts from the tibia superiorly, laterally, and posteriorly to its insertion on the posterior aspect of the medial wall of the lateral femoral condyle. The ACL is composed of 2...

The anterior cruciate ligament (ACL) is one of the most commonly injured ligaments of the knee. Injuries occur predominately in a young and sports-active population. Many patients are left with significant disability following injury to the ACL. Understanding and preventing associated meniscal pathology is the key to management of this...

Anterior cruciate ligament rupture, whether treated surgically or not, is associated with an increase in osteoarthritis in former soccer players.
J Feller Br J Sports Med. 2004 Aug;38(4):383-4.

The anterior cruciate ligament traverses the knee joint from the tibial spines to the medial aspect of the lateral femoral condyle in the notch. The function of the anterior cruciate ligament is primarily to resist anterior tibial subluxation. Injuries to the anterior cruciate ligament involve traumatic disruption of the normal ligament...

Dr. Daniel B. O'Neill of Nassau Bay, Texas demonstrates his technique for Arthroscopically assisted reconstruction of the ACL deficient knee using a patellar bone-patellar ligament-tibial tubercle bone autograft. In-depth discussion on surgical indications, contraindications, graft selection, fixation options and postoperative protocol is presented. During surgery, Dr. O'Neill provides several "pearls"...

The following is a summary of an article by Traina and Bromberg in Orthopedics Vol 20 No 6 June 1997 In the NCAA, the Injury rates are 2.4X greater in soccer and 4.1 X greater in basketball for female athletes. The reason for this increase is still speculative, but there are...
