Tunnel enlargement 5 years after anterior cruciate ligament reconstruction: a radiographic and functional evaluation.

Purpose: The aetiology and clinical significance of enlargement of bone tunnels following anterior cruciate ligament (ACL) reconstruction remains controversial. This phenomenon has been attributed to biological factors and mechanical factors. We wanted to study the amount of femoral and tibial tunnel enlargement 5 years post-ACL reconstruction.

The relationship of the lateral cord of the brachial plexus to the coracoid process during arthroscopic coracoid surgery: a dynamic cadaveric study.

Background: Arthroscopic coracoid decompression is performed for coracoid impingement and has also been advocated for arthroscopic repair of tears of the subscapularis tendon, placing the lateral cord or the musculocutaneous nerve at risk of injury. The dynamic relationship of the lateral cord to the coracoid while the upper limb is in abduction and traction in the shoulder arthroscopy position is not clear.

Purpose: The purpose of this study was to evaluate the dynamic relationship of the lateral cord of the brachial plexus to the coracoid process during varying degrees of upper limb abduction in traction.

Return to sports after anterior cruciate ligament reconstruction - a review of patients with minimum 5-year follow-up.

Introduction: It is difficult to counsel the anterior cruciate ligament (ACL) deficient patient considering surgical reconstruction on the likelihood of eventual return to sports as information on this is lacking, especially in the Asian context. We wanted to determine how many of our patients who had ACL surgery returned to their previous levels of sports, 5 years after their surgery. For those that had not returned to their previous levels of sports, we wanted to identify their reasons for not doing so.

Clinical evaluation of arthroscopic-assisted allograft meniscal transplantation.

Introduction: A meniscal deficient knee is at risk of early degenerative osteoarthritis. Allograft meniscal transplantation has been used to treat the meniscus deficiency to alleviate pain symptoms and to delay progression to arthritis. This case series aims to assess the postoperative outcomes of patients who have undergone meniscal allograft transplantation in our hospital.
