PURPOSE To validate the functional performance tests (FPTs) after anterior cruciate ligament (ACL) reconstruction. MATERIALS AND METHODS Thirty men in their third decade after ACL reconstruction at 6 month follow-up and thirty healthy subjects were selected. Lysholm knee score, International Knee Documentation Committee (IKDC) subjective score, Tegner activity score, KT-2000 arthrometer test,...

Reconstruction of a ruptured anterior cruciate ligament (ACL) is a well-established procedure for repair of ACL injury. Despite improvement of surgical and rehabilitation techniques over the past decades, up to 25% of patients still fail to regain satisfactory function after an ACL reconstruction. With development of CT imaging techniques for reducing metal artifacts, multi-planar reconstructio...

PURPOSE The purpose of this study was to compare the clinical outcomes of arthroscopic anatomical double bundle (DB) anterior cruciate ligament (ACL) reconstruction with either selective anteromedial (AM) or posterolateral (PL) bundle reconstruction while preserving a relatively healthy ACL bundle. MATERIALS AND METHODS The authors evaluated 98 patients with a mean follow-up of 30.8±4.0 month...

Historically, patient perceptions of surgeon reimbursement have been exaggerated compared with actual reimbursement. There is limited information about patient perceptions of physician reimbursement for arthroscopic meniscectomy and anterior cruciate ligament (ACL) reconstruction. This study evaluated patient perceptions of physician reimbursement for these procedures and compared perceptions o...

The characteristics of anterior cruciate ligament (ACL)-derived mesenchymal stem cells (MSCs), such as proportion and multilineage potential, can be affected by donor age. However, the qualitative and quantitative features of ACL MSCs isolated from younger and older individuals have not yet been compared directly. This study assessed the phenotypic and functional differences in ACL-MSCs isolate...

BACKGROUND one of the most recent technique is the "all inside" anterior cruciate ligament (ACL) reconstruction. One of the main characteristic of this procedure is the sparing of the tibial cortex. Furthermore, the all-inside technique requires only one tendon harvested. PURPOSE the present study describes two year clinical outcomes of the all-inside method for ACL reconstruction, and compar...

Double-bundle (DB) anterior cruciate ligament (ACL) reconstruction using a four-strand semitendinosus tendon was started in our department in July 1994. The motivation for starting the procedure was that the EndoButton with an inside-out procedure instrument became available in Japan. A review article of our DB ACL reconstruction procedure was summarized for the twentieth anniversary of the sur...

BACKGROUND Attempts have been made to validate the significance of remnant preservation with anterior cruciate ligament (ACL) reconstruction using immunohistochemical and immunocytochemical techniques. The purpose of this study was to examine the expression of mechanoreceptors in the remnant tissue of ACL reconstruction performed with the remnant-preserving technique. METHODS Tissue samples w...

UNLABELLED Anterior cruciate ligament (ACL) injuries remain a common orthopaedic disease, particularly in young adults. The treatment of choice for ACL injuries is ACL reconstruction (ligamentoplasty). ACL reconstruction is the surgical intervention used to replace the damaged ACL with a bone-patella tendon-bone (BTB) graft or with soft parts (semitendinosus - gracilis muscles (ST-G) - a method...

PURPOSE Anterior cruciate ligament (ACL) reconstruction is commonly performed in athletes, with the goal of return to sports activities. Unfortunately, this operation may fail, and the rates of either reinjuring an ACL-reconstructed knee or sustaining an ACL rupture to the contralateral knee range from 3% to 49%. One problem that exists is a lack of information and consensus regarding the appro...
