ABSTRACT
BACKGROUND: The anterior cruciate ligament (ACL) takes part in the knees articular cinematic regulation, which is why its rupture should be repaired as soon as possible. The surgical treatment is targeted to substitute the ruptured ACL with a graft that recreates the anatomical and biomechanical functions. Nevertheless, there are different factors that may produce a second rupture. OBJECTIVE: To determine the risk factors and frequency of failure in the ACL reconstruction. MATERIAL AND METHODS: Retrospective study evaluating the frequency and etiology of the failure in the ACL reconstruction in an adult population during a three-year period. Risk factors such as age, gender, trauma background, previous joint injuries, type of the graft previously used, lapse between surgeries, lapse between rupture and surgery and other comorbidities were analyzed. RESULTS: We obtained 34 patients with ACL reconstruction failure and 111 with native ACL rupture (145 patients in total). In the ACL reconstruction failure group, 31 were males with an average age of 33 years, produced by a traumatic mechanism (85.2%) and with other associated injuries (41%). CONCLUSIONS: We found a significant statistical association for graft failure with male patients, traumatic mechanism, isolated cartilage lesions or combined articular injuries.
El ligamento cruzado anterior (LCA) participa en la regulación de la cinemática articular de la rodilla, por lo que su ruptura debe repararse lo antes posible. El tratamiento quirúrgico está encaminado a la sustitución del LCA roto por un injerto que lo reemplazará tanto anatómica como biomecánicamente. Sin embargo, se pueden presentar diferentes condiciones que produzcan una rerruptura.

INTRODUCTION: Hyaluronic acid is a major component of synovial fluid and cartilage; it plays an essential role in joint function. This concept is based on the hypothesis that intraarticular sodium hyaluronate injections improve articular function upon restoring synovial fluid viscosupplementation and promoting endogenous synthesis. MATERIAL AND METHODS: Forty randomly selected patients older than 50 years of age, with a diagnosis of gonarthrosis, standard treatment-naïve, were divided into two 20-patient groups. The first group was treated with five 2.5 ml doses of hyaluronic acid, at one dose per week. The second group was treated with a single 2 ml dose of intraarticular methylprednisolone. A survey containing the Womac functional scale and the pain visual analogue scale was applied to both groups before and 3 months after treatment. RESULTS: A statistically significant reduction in pain (visual analogue scale) was observed 3 months after treatment in group H (1.6 +/- 0.88) and group M (2.95 +/- 1.84), as well as a functional post-treatment improvement in the Womac scale. Results for post-treatment pain were 5.43 +/- 1.05 for group H and 7.86 +/- 0.77 for group M; results for post-treatment stiffness were 3.05 +/- 0.82 for group H and 3.7 +/- 0.85 for group M; and finally for post-treatment functional capacity the results were 12.25 +/- 0.82 for group H and 18.95 +/- 0.85 for group M. CONCLUSION: Intraarticular sodium hyaluronate is more effective for pain and function than methylprednisolone. However, it involves higher costs than conservative treatment and fewer costs than surgical treatment, as well as the discomfort resulting from repeated intraarticular injections and the possibility of anaphylactic reaction.
