Validation of a histologic scoring system for the examination of quality of tendon graft to bone tunnel healing in anterior cruciate ligament reconstruction.

Objective: To develop and validate a histologic scoring system for the assessment of tendon graft to bone tunnel healing in anterior cruciate ligament (ACL) reconstruction.

Study Design: The scoring system, tendon-bone tunnel healing (TBTH) score, comprised 5 items on graft status,fiber type and interface connectivity, evaluated on either a 5- or 6-point scale. Two observers were trained to use the scoring system, examining 15 blinded histologic slides from an ongoing study.

Inferior tendon graft to bone tunnel healing at the tibia compared to that at the femur after anterior cruciate ligament reconstruction.

Background: Tunnel widening after anterior cruciate ligament (ACL) reconstruction (ACLR) is commonly reported without a clear understanding of the mechanism. This study aimed to quantify the spatiotemporal change of the newly formed bone mass, bone tunnel diameter, and area along both bone tunnels using micro-computed tomography (microCT) and correlated the result with histology.

Methods: ACLR was performed in 24 rabbits.

Neurilemmoma of the first branch of the lateral plantar nerve causing tarsal tunnel syndrome.

In this article, the authors report a case of tarsal tunnel syndrome caused by neurilemmoma of the first branch of the lateral plantar nerve, with symptom resolved after excision. A 42-year-old man presented with left medial heel pain radiating to the lateral sole for 6 months. On examination, there was positive Tinel sign over the medial heel with pain radiating to the lateral sole.

Arthroscopic resection of volar ganglion of the wrist: A new technique.

We evaluated a new arthroscopic technique for treating volar ganglion of the wrist. Arthroscopic resection of volar wrist ganglion was performed under local anesthesia to the portal sites. Arthroscopic instruments were introduced dorsally, and the intra-articular lesion at the interval between the radioscaphocapitate (RSC) and long radiolunate (LRL) ligaments was debrided under direct view.
