Meniscal Repair Outcome in 3829 Patients With a Minimum Follow-up From 2 Years Up to 5 Years: A Meta-analysis on the Overall Failure Rate and Factors Influencing Failure.

Background: The importance of meniscal repair is widely accepted because of the association of loss of meniscal tissue with the development of early-onset knee arthritis. Many factors influencing the results of meniscal repair have been reported, but results remain controversial.

Purpose: This meta-analysis determines the pooled meniscal repair failure rate of studies with a minimum follow-up of 2 years up to 5 years, with a mean follow-up of 43 months.

Biomechanical Comparison of Anterior Cruciate Ligament Reconstruction Using a Single-Bundle Round or Ribbon-like Hamstring Tendon Graft.

Background: Persistent instability of the knee is reported in up to 30% of patients after anterior cruciate ligament (ACL) reconstruction. Based on anatomic findings showing that ACL is a flat ribbon-like structure that twists during knee flexion, a new surgical ACL reconstruction technique using a ribbon-like graft has been developed. However the effect of this surgical technique on knee kinematics has not yet been evaluated.

Joint fluid concentrations of amphotericin B after local application with calcium sulphate-report of 2 cases.

Fungal periprosthetic joint infections (PJI) are difficult to treat, due to important biofilm formation and limited local penetration of systemically administered antifungals. Calcium sulphate (CaSO ) might be a promising carrier to increase local concentration of antifungals. We hypothesized that local amphotericin B release from CaSO is high enough to significantly contribute to treatment of fungal PJI.

[Unicompartmental knee arthroplasty - a solution?].

Unicompartmental knee arthroplasty - a solution? Unicompartmental knee arthroplasty (UKA) has various advantages over total knee arthroplasty (TKA); however, national joint registries communicate a significantly higher revision rate. Nevertheless, good results with high patient satisfaction can be achieved by appropriate patient selection. The good functional outcome may be due to the philosophy of the procedure, since the unicompartmental joint replacement is a pure resurfacing replacement, which aims to restore the individual, variable native, pre-arthrotic alignment, joint line and knee laxity, thus respecting the kinematics of the native knee joint.

Femoral insertion site in medial patellofemoral ligament reconstruction.

Background: The optimal femoral insertion point in MPFL (medial patellofemoral ligament)-reconstruction still remains ambiguous. Three-dimensional knee simulations based on computerized tomography (CT) images acquired under physiological loading conditions give further insights to predict the optimal femoral insertion site of the MPFL. The hypothesis of the present study is that the optimal insertion point is not as reliable as thought and is dependent on subject-specific anatomical factors.

Unicompartmental knee arthroplasty MRI: impact of slice-encoding for metal artefact correction MRI on image quality, findings and therapy decision.

Objectives: To evaluate the impact of slice-encoding for metal artefact correction (SEMAC) on image quality, findings, and therapy decision in patients with unicompartmental knee arthroplasty (UKA).

Methods: Forty-five painful UKAs were examined at 1.5T-MRI (STIR, proton-density(PD)-weighted sequence, each with SEMAC and high-bandwidth).

Complications after epiphyseal reconstruction of the anterior cruciate ligament in prepubescent children.

Purpose: Reconstruction of the anterior cruciate ligament (ACL) remains a major concern in the prepubescent, skeletally immature patient with wide open growth plates. Different surgical techniques have been proposed. This study reports the results and complications of ACL reconstruction in young children using an all epiphyseal technique.

Early serum procalcitonin level after primary total hip replacement.

Background: Procalcitonin (PCT) is a useful surrogate marker for the differentiation of postoperative infection and unspecific inflammatory reaction after surgery. It is known that postoperative course of the PCT serum level varies with type of surgery. No data exists about the postoperative course of serum PCT levels after primary total hip replacement (THR).

Spontaneous reduction of spondylolisthesis during growth: a case report.

Isthmic spondylolisthesis is a common cause of low back pain in children. It is associated with a defect in the pars interarticularis of the vertebra. The treatment depends on the clinical course and degree of spondylolisthesis.
