OBJECTIVE: To determine the initial resistance of fixation using the Rigid Fix(®) system, and compare it with traditional fixation methods using metal interference screws; and to evaluate the resistance of the fixation with the rigid fix system when the rotational position of the bone block is altered in the interior of the femoral tunnel. METHODS: forty ovine knee specimens (stifle joints) were submitted to anterior cruciate ligament reconstruction (ACL) using a bone-tendon-bone graft...

BACKGROUND: There is a high incidence of anterior cruciate ligament (ACL) injuries among National Football League (NFL) athletes; however, the incidence of reinjury in this population is unknown. PURPOSE: This retrospective epidemiological study analyzed all publicly disclosed ACL tears occurring in NFL players between 2010 and 2013 to characterize injury trends and determine the incidence of reinjury. STUDY DESIGN: Descriptive epidemiological study...

BACKGROUND: Knee injuries with interior cruciate ligament rupture or strain are one of more common and more complicate ones for diagnosis, operation and multistage rehabilitation. The purpose of this study was assessment of force - velocity parameters of knee flexors and extensors in patients 13 weeks after anterior cruciate ligament reconstruction. MATERIAL AND METHODS: 13 men, aged 18- 34 years participated in this research. Anterior cruciate ligament reconstruction in 4 Polyclinic in Wrocław was carried out in each subjects...

Anterior cruciate ligament (ACL) injury is a major problem worldwide and prevails during high-impact activities. It is not well-understood how the extent and distribution of cartilage damage will arise from repetitive landing impact loads that can lead to ACL failure. This study seeks to investigate the sole effect of repetitive incremental landing impact loads on the induction of ACL failure, and extent and distribution of tibiofemoral cartilage damage in cadaveric knees. Five cadaveric knees were mounted onto a material testing system at 70 degrees flexion to simulate landing posture...

BACKGROUND: Anterior cruciate ligament (ACL) injury incurred from high-impact activities leads to an increased risk of osteoarthritis. HYPOTHESIS: Impact forces that cause ACL failure can also inflict cartilage damage, whereby its extent and distribution may be influenced by the ligament failure mechanism. STUDY DESIGN: Descriptive laboratory study. METHODS: Six porcine knee specimens were mounted to a material testing system at 70 degrees of flexion...

OBJECTIVE: To investigate the method and result of arthroscopic trans-septal approach (ATS). METHODS: Ten fresh cadaveric knees were prepared for anatomical study about the posterior septum, and 65 posterior compartment arthroscopy of the knees were performed to view the structure of the posterior septum. The initial diagnosis included: rheumatoid arthritis, pigmented villonodular synovitis, osteoarthritis, loose body or foreign body in the posterior compartment, posterior cruciate ligament (PCL) injury or avulsion fracture, posterior horn tear of meniscus, undiagnosed swollen knee with pain and effusion, osteochondritis dissecans, pyogenic arthritis, gout...

In this paper the design and experimental analysis is presented of a new fixation device of anterior cruciate ligament (ACL) grafts of the knee. This device is inserted into the bone tunnel, after the graft, in the same way as an interference screw. However, the fixation device described in this paper has been designed in such a way that, after the insertion of a threaded element in its interior, some of its components expand in a radial direction, pressing against the walls of the bone tunnel and thereby increasing the fixation of the graft...

OBJECTIVES: We evaluated the frequency, anatomic types, and predisposing factors of knee ligament injuries that occur in skiers during a winter season at the Uludag Ski Center, Bursa, Turkey. METHODS: A total of 215 patients (240 knees) presented to the Uludag University-Sabanci Health Center after sustaining a skier knee injury during the 2003-2004 winter season. The mean patient age was 31 years (range 9 to 55 years). Knee ligament injuries were assessed according to the AOSSM (American Orthopaedic Society for Sports Medicine) criteria...

The human meniscus is subject to injury that necessitates repair or removal. Many aspects of the cellular response to injury have not been well characterized. The purpose of this study was to describe the cellular distributions within the torn human meniscus. In addition to evaluating the cell density in selected regions, we investigated the cellular expression of a contractile actin isoform that has recently been found in the intact human meniscus. Included as a contemporaneous comparative group were torn human meniscal allografts...

Investigations were carried out on 43 serially sectioned human embryos of developmental stages 18 to 23. The homogeneous interzone of the future knee joint is observed in embryos at stage 18. During stage 19 this interzone is differentiated into dense, intensively stained, peripheral parts, which are the primordia of menisci and the medial portion, in which the cruciate ligaments are formed. All structures of the interior of the knee joint are more clearly delineated during stage 20, and they are well developed during the last embryonic week (stages 21-23)...

The objective of this study was to observe the changing appearance of human anterior cruciate ligament (ACL) grafts in their tibial bone tunnels by MRI using oblique axial images. One-hundred and eight knees in 75 patients were studied by MRI at 1-33 months after arthroscopic ACL reconstructions using double-looped, autogenous semitendinosus and/or gracilis tendons. Knees with poor stability were excluded from this study. The examinations were performed at 0.2T with spin echo proton density and T2-weighted oblique axial images...

An anterior cruciate ligament tear before or early in an athlete's season presents a treatment dilemma: surgically repair the ligament and end the season, or use rehabilitative exercises and bracing to quickly return the athlete to play. We conducted a prospective study of 43 athletes (44 acute tears) over 44 months to determine criteria for early return to play and if an early return is safe. All patients had an acute injury in a previously normal knee, a positive Lachman test, and KT-1000 arthrometry indicating ligament abnormalities...

A 3-year prospective study was initiated to evaluate torsional resistance of modern football cleat designs and the incidence of surgically documented anterior cruciate ligament tears in high school football players wearing different cleat types. We compared four styles of football shoes and evaluated the incidence of anterior cruciate ligament tears among 3119 high school football players during the 1989 to 1991 competitive seasons. The four cleat designs were 1) Edge, longer irregular cleats placed at the peripheral margin of the sole with a number of smaller pointed cleats positioned interiorly (number of players wearing this shoe, 2231); 2) Flat, cleats on the forefoot are the same height, shape, and diameter, such as found on the soccer-style shoe (N = 832); 3) Screw-in, seven screw-in cleats of 0...

Between August 1980 and December 1986, 120 patients suffering from chronic instabilities of the knee ligament were submitted to corrective surgery at the Berufsgenossenschaftliche Unfallklinik Frankfurt am Main. A textile ligament made of polyethylene terephthalate (Trevira hochfest type 730) was substituted in all cases for the disturbed or missing ligament structure. 67 out of 100 patients came to the check-up appointments. A precise and objective comparison between the preoperative and postoperative findings of each patient was now possible for the first time thanks to the most recent computer technique...
