Bone defects caused by femoral and tibial tunnel enlargement can pose a significant technical challenge when planning to perform revision anterior cruciate ligament reconstruction. A number of options have been described for managing osseous deficiencies, including the use of large autograft or allograft bone dowels to provide sufficient tunnel fill and subsequent structural support for revisio...

Bone-patellar tendon-bone graft has been an attractive option for single-bundle anterior cruciate ligament reconstruction in clinical practice. However, the graft-tunnel mismatch in the proximal part of the tibial tunnel and the ultimate strength after postoperative ligamentization process have been potential problems for the traditional 10-mm wide graft. We modified the traditional bone-patell...

Nineteen patients with roof impingement of an anterior cruciate ligament graft had their grafts inspected during second-look arthroscopy. The diagnosis of roof impingement was suspected from the clinical findings of an effusion, extension deficit, recurrent instability, or anterior knee pain. The diagnosis was confirmed when a portion of the tibial tunnel was anterior to the tibial intersection...

Currently, the most common method for drilling the femoral tunnel in anterior cruciate ligament reconstruction (ACLR) employs a trans-tibial technique. A new technique, utilising anteromedial portal drilling has been shown to produce a more anatomical placement of the femoral tunnel than trans-tibial (1). A further recent development is the concept of anatomical anterior cruciate ligament recon...

Introduction: Single-bundle anterior cruciate ligament (ACL) reconstruction has been the standard option to treat ACL-deficient knees. However, biomechanical studies have shown that normal rotational laxity cannot be restored with single-bundle reconstructions [1]. Recently, anatomic reconstruction of the anteromedial (AM) and posterolateral (PL) bundles has been introduced [2]. However, it rem...

Impaired glucose tolerance creates a peripheral nervous system that is susceptible to chronic nerve compression. While it is accepted that surgical decompression of the median nerve at the wrist, for carpal tunnel syndrome, is appropriate in the diabetic, application of this concept to the lower extremity has not yet gained widespread recognition. Traditional electrodiagnostic studies demonstra...

BACKGROUND We previously developed a novel technique using an alternate soaking process that improves tendon-bone healing by hybridizing the tendon graft with calcium phosphate (CaP). However, the effects of the CaP-hybridized tendon graft on anatomic single-bundle anterior cruciate ligament (ACL) reconstruction remain unclear. PURPOSE To determine the effects of CaP-hybridized tendon grafts ...

Anatomic ACL reconstruction is the reasonable approach to restore stability without loss of motion after ACL tear. To mimic the normal ACL like a ribbon, our preferred procedures is the anatomic rectangular tunnel (ART) technique with a bone-patellar tendon-bone (BTB) graft or the anatomic triple bundle (ATB) procedure with a hamstring (HS) tendon graft. It is important to create tunnel apertur...

A rare anomaly of a nonterminating tibial nerve is reported. It was found to be associated with tarsal tunnel syndrome. The nerve failed to divide in the tarsal tunnel and in the talocalcaneal canal distally to the Knot of Henry. The branches of the medial and lateral plantar nerves as well as the medial calcaneal nerve, the nerve to the abductor digiti quinti, and motor branches to the abducto...
