[Posterior cruciate ligament rupture : state of the art].

Posterior cruciate ligament (PCL) ruptures can cause severe knee instability and disability and thus, appropriate management is crucial for the successful restoration of patients' knee function. Rupture of the PCL can occur during sporting activity but more often, as a part of high-energy trauma. The diagnosis can be made using various clinical tests, such as the posterior drawer test or the quadriceps active test.

Midterm results of combined intra- and extra-articular ACL reconstruction compared to historical ACL reconstruction data. Multicenter study of the French Arthroscopy Society.

Introduction: During anterior cruciate ligament (ACL) reconstruction procedures, anterolateral reconstruction (ALR) can also be performed to improve the knee's rotational stability. However, the effectiveness of this supplemental technique and its impact on the risk of retears and on the onset of secondary degenerative changesare controversial.

Hypothesis: ALR improves control over the pivot shift, reduces the retear risk and delays the appearance of secondary degenerative lesions.

Short-term complications in intra- and extra-articular anterior cruciate ligament reconstruction. Comparison with the literature on isolated intra-articular reconstruction. A multicenter study by the French Arthroscopy Society.

Introduction: Lateral tenodesis (LT) is performed to limit the risk of iterative tear following anterior cruciate ligament (ACL) reconstruction in at-risk patients. By adding an extra procedure to isolated ACL graft, LT reconstruction increases operating time and may complicate postoperative course. The objective of the present study was to evaluate the rate of early complications.

What are the risk factors for dislocation in primary total hip arthroplasty? A multicenter case-control study of 128 unstable and 438 stable hips.

Introduction: Dislocation after total hip arthroplasty (THA) is a leading reason for surgical revision. The risk factors for dislocation are controversial, particularly those related to the patient and to the surgical procedure itself. The differences in opinion on the impact of these factors stem from the fact they are often evaluated using retrospective studies or in limited patient populations.

Chronic low back pain after lumbosacral fracture due to sagittal and frontal vertebral imbalance.

Problem And Hypothesis: Over time, some patients with unilateral or bilateral lumbosacral injuries experience chronic low back pain. We studied the sagittal and frontal balance in a population with these injuries to determine whether mismatch in the pelvic and lumbar angles are associated with chronic low back pain.

Patients And Methods: Patients with posterior pelvic ring fractures (Tile C1, C2, C3 and A3.

Outcome of cartilage at 12years of follow-up after anterior cruciate ligament reconstruction.

Introduction: In cases of chronic anterior laxity, reconstruction of the anterior cruciate ligament (ACL) can slow the development of osteoarthritis. This study was conducted to determine the overall prevalence of osteoarthritis and to identify the risk factors after ACL reconstruction.

Hypothesis: Meniscus tears, time from injury to surgery, body mass index (BMI), residual laxity, and cartilage lesions influence the progression towards osteoarthritis.

Long-term outcomes of tension band wiring with a single K-wire in Rockwood type IV/V acute acromio-clavicular dislocations: 25 cases.

Background: Our objective was to evaluate the long-term functional and radiological outcomes of tension band wiring with a single K-wire for acute Rockwood types IV and V acromio-clavicular dislocation (ACD).

Methods: Single-centre cross-sectional non-randomised observational cohort study of 25 shoulders treated surgically between January 2002 and December 2004, in 25 patients, 23 males and 2 females, with a mean age of 35±11years (24-46). The evaluation criteria were the absolute and weighted Constant scores, QuickDASH score, subjective shoulder value (SSV), visual analogue scale (VAS) pain score at rest and during activities, and radiographic features in clinically symptomatic patients.

Non-operative treatment of four-part fractures of the proximal end of the humerus: results of a prospective and retrospective multicentric study.

Purpose: The aim of this study was to evaluate the short- and medium-term results of non-operative treatment of four-part fractures of the proximal end of the humerus. The initial hypothesis was that non-operative treatment of fractures with little or no displacement is equivalent or superior to surgical treatment, and that non-operative treatment is probably insufficient for displaced fractures.

Methods: This was a multicentric, prospective and retrospective study, based on 384 four-part proximal humerus fractures, 58 of which involved non-operative treatments - 37 in the prospective study (Pro-CT4) and 21 in the retrospective study (Retro-CT4).

Meniscoplasty for lateral discoid meniscus tears: Long-term results of 14 cases.

Introduction: Discoid lateral meniscus lesions are relatively rare. The objective of this study was to determine the long-term results of 14 cases of discoid lateral meniscus tears treated by arthroscopic meniscoplasty between July 1991 and May 2009, and to assess the development of osteoarthritis in the lateral compartment.

Methods: The series consisted of 10 patients (14 knees): 3 girls under the age of 15, 3 men and 4 women aged from 16 to 47 years (mean age: 31.

Clinical and radiological outcomes with the Durom™ acetabular cup for large-diameter total hip arthroplasty: 177 implants after a mean of 80 months.

Background: Large-diameter metal-on-metal hip prostheses are no longer used, but their outcomes after more than 5 years are unknown. We conducted a retrospective study with a 6.8-year mean follow-up to assess clinical outcomes after Durom™ cup implantation, including the dislocation rate, comparatively to the reference metal-on-polyethylene bearing.

Return to sports after autogenous osteochondral mosaicplasty of the femoral condyles: 25 cases at a mean follow-up of 9 years.

Introduction: Autogenous osteochondral mosaicplasty is the most common cartilage restoration technique in standard clinical practice. The purpose of this study was to evaluate the return to sports 9 years after mosaicplasty of the femoral condyles.

Hypothesis: The long-term results of an osteochondral autograft show that patients can regain their pre-injury activity level.

Acute traumatic patellar tendon rupture: Early and late results of surgical treatment of 38 cases.

Introduction: Acute patellar tendon rupture is easy to diagnose but is still often overlooked. The aim of this study was to assess early and late results of surgical treatment of acute patellar tendon rupture. Our hypothesis was that functional outcome is satisfactory.

Computer-assisted osteotomy for valgus knees: medium-term results of 29 cases.

Introduction: Computer-assisted surgery has been shown to be beneficial for correcting misaligned lower limbs. The purpose of this study was to analyze the medium-term results of computer-assisted osteotomy for 29 valgus knees. The hypothesis was that computer navigation would allow a valgus deformity to be corrected with similar precision as varus deformity.
