A comparison of the outcomes of anterior curciate ligament reconstruction with large-size graft versus reconstruction with average-size graft combined with extraarticular tenodesis.

Introduction: Many patients who have had anterior cruciate ligament (ACL) reconstruction (R) complain of instability, inability to return to previous levels of sports activity, and possible ACL graft failure. Graft size was discovered to be an important factor in lowering ACL failure rates. Also, extraarticular tenodesis decreases recurrent instability, A comparative study was done to compare the effect of graft size and lateral external tenodesis on the recurrence of instability after ACL-R.

A prospective comparative study between percutaneous cannulated screws and Kirschner wires in treatment of displaced intra-articular calcaneal fractures.

Purpose: Several minimally invasive procedures were used to treat displaced intra-articular calcaneal fractures (DIACFs). No agreement among different authors about either the ideal fixation method or which technique is minimally invasive. The aim of this study was to compare functional and radiographic outcomes of two minimally invasive techniques in treatment of Sanders type II and III DIACFs by using K-wires or cannulated screws without bone grafts.

Contrasting the efficacy of pulsed dye laser and photodynamic methylene blue nanoemulgel therapy in treating acne vulgaris.

The treatment of acne remains a challenge for dermatologists. A variety of conventional therapies are available for acne treatment such as topical and systemic medications. Although many of these traditional acne treatments are effective, the wide-spread nature of the disease and its sometimes resistant nature delineate the need for alternative therapies.

Investigation of thermoluminescence glow curves in quartz extracted from the Central Eastern Desert, Egypt.

The current study investigated the thermoluminescence (TL) properties of milky quartz samples collected from the Central Eastern Desert, Egypt. The crystallinity and the elemental concentrations of the milky quartz samples were examined using X-ray diffraction and an atomic absorption spectrometer. Samples were irradiated using a gamma source at different doses from 250 mGy up to 2 kGy.

Toll-like receptors-2 and -9 (TLR2 and TLR9) gene polymorphism in patients with type 2 diabetes and diabetic foot.

Toll-like receptors (TLRs) are innate immune receptors that mediate the inflammatory response in diabetes mellitus (DM). The aim of this study is to evaluate the association of TLR2 and TLR9 gene polymorphism in patients with type 2 DM (T2DM) and diabetic foot (DF).The study included 90 subjects divided into group I (30 patients with T2DM and DF), group II (30 patients with T2DM and no evidence of DF), and group III (normal control subjects).

Long-term follow-up after latissimus dorsi transfer for irreparable posterosuperior rotator cuff tears.

Background: Irreparable posterosuperior rotator cuff tears are treated in several ways. Transfer of the latissimus dorsi is an alternative with acceptable mid-term results, but long-term results have rarely been published.

Methods: The cases of 108 consecutive patients with 115 shoulders treated with latissimus dorsi transfer between 2000 and 2005 were reviewed clinically and radiographically.

Methylenetetrahydrofolate reductase C677T and A1298C polymorphism and susceptibility to acute lymphoblastic leukemia in a cohort of Egyptian children.

This case-control study was planned to investigate the possible role of methylenetetrahydrofolate reductase (MTHFR) C677T and A1298C polymorphisms as a risk factor for the development of acute lymphoblastic leukemia (ALL) in a cohort of Egyptian children. Typing of MTHFR C677T and A1298C polymorphisms was done using restriction fragment length polymorphism (RFLP) for 100 children with ALL and 100 age- and sex-matched healthy controls. No significant differences were found between patients with ALL and controls for the frequency of MTHFR C677T and A1298C alleles, genotypes, combined genotypes or haplotypes.

Sports activity after osteochondral transplantation of the talus.

Background: There are limited data regarding activity after osteochondral transplantation of the talus in orthopaedic publications.

Hypothesis: Osteochondral transplantation of the talus is a clinically successful treatment and enables patients to pursue regular and ongoing recreational sporting activities.

Study Design: Case series; Level of evidence, 4.

Limb alignment after open-wedge high tibial osteotomy and its effect on the clinical outcome.

The purpose of this study was to evaluate the accuracy of alignment after open-wedge high tibial osteotomy and its effect on the clinical outcome. A prospective case series of 56 consecutive patients underwent open-wedge high tibial osteotomy fixed with a TomoFix plate fixator (Synthes, West Chester, Pennsylvania). The correction angle was radiologically determined preoperatively and at 6 months postoperatively.

Clinical and structural evaluation of arthroscopic double-row suture-bridge rotator cuff repair: early results of a novel technique.

Purpose: Assessment of repair integrity and clinical outcome after arthroscopic repair of rotator cuff tears in double-row suture-bridge technique with the use of a new knotless suture-anchor system.

Methods: The first treated 25 patients with arthroscopic rotator cuff repair in the suture-bridge technique using a novel knotless anchor and chain-link suture system were evaluated. Patients with isolated full-thickness supraspinatus tears were selected.

Patellar height and posterior tibial slope after open- and closed-wedge high tibial osteotomy: a radiological study on 100 patients.

Background: Valgus high tibial osteotomy (HTO) may be associated with changes in the patellar height and posterior tibial slope.

Hypothesis: Patellar height increases and posterior tibial slope decreases after closed-wedge HTO, whereas patellar height decreases and tibial slope increases after open-wedge osteotomy.

Study Design: Cohort study; Level of evidence, 3.

Sporting activity after high tibial osteotomy for the treatment of medial compartment knee osteoarthritis.

Background: Isolated varus osteoarthritis of the knee is a common problem in patients engaged in sports and recreational activities.

Hypothesis: Patients will be able to resume sporting activity after high tibial osteotomy.

Study Design: Case series; Level of evidence, 4.

The effect of closed- and open-wedge high tibial osteotomy on tibial slope: a retrospective radiological review of 120 cases.

Radiographs of 110 patients who had undergone 120 high tibial osteotomies (60 closed-wedge, 60 open-wedge) were assessed for posterior tibial slope before and after operation, and before removal of the hardware. In the closed-wedge group the mean slope was 5.7 degrees (SD 3.

Incidence of associated injuries with acute acromioclavicular joint dislocations types III through V.

Background: Traumatic acromioclavicular (AC) joint dislocations are common injuries among the active population. The injury mechanism requires excessive force delivered by a fall or blow to the shoulder. Associated injuries may occur and remain undetected if they are masked by the painful and prominent AC joint injury.
