Purpose The aims of this study were to evaluate the clinical and radiological outcome, sum of acetabular and femoral cartilage thickness and rate of failure in the mid-term following the arthroscopic treatment of femoroacetabular impingement (FAI) syndrome with femoral osteoplasty, labral repair and rim trimming without labral detachment. Methods...

Most surgeons create a T-shaped or interportal capsulotomy to ensure good visibility when performing hip arthroscopy. This entails transecting the iliofemoral ligament, which may or may not be repaired at the end of the procedure. Cases of iatrogenic hip instability and pain after hip arthroscopy suggest that the iliofemoral ligament plays a crucia...

Background: Medial UKA performed in England and Wales represents seven to 11% of all knee arthroplasty procedures, and is most commonly performed using mobile-bearing designs. Fixed bearing eliminates the risk of bearing dislocation, however some studies have shown higher revision rates for all-polyethylene tibial components compared to those that...

Purpose: To perform a systematic review comparing outcomes of labral debridement/segmental resection with labral reconstruction as part of a comprehensive treatment strategy for femoroacetabular impingement. Methods: A systematic review was conducted according to established PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analy...

Despite intensive research, current total knee arthroplasty (TKA) designs do not always provide the correct kinematics for the native joint and thus further optimisation is necessary. Several studies support the importance of malrotation of the tibial components in the failure of TKA. We hypothesise that using the anatomical tibial axis (ATA) to al...

Total hip replacement is one of the most successful surgical procedures of the 20th century (World Health Organisation). The success rate is dependent on the chosen endpoint. Evaluation of the outcome in joint replacement surgery has shifted from the revision rate toward patient satisfaction and quality of life. Patient satisfaction is reported to...

Synovial biopsies of the knee joint are commonly performed arthroscopically with the patient under full or regional anesthesia. To overcome the effort, costs, and potential risks of surgery, we developed an office-based technique for retrograde synovial biopsy using a designated novel biopsy forceps. Using this technique, no arthroscopic or radiolo...

Treatment of osteoporotic fractures with conventional surgical methods is associated with a high rate of complications. Intense search for new treatment options includes development of specific biomaterials aimed to be part of the surgical armamentarium. Strontium doped calcium phosphate spheres (SrCPS) is a new material that might be of interest d...

In this work a radiopaque premixed calcium phosphate cement (pCPC) has been developed and evaluated in vivo. Radiopacity was obtained by adding 0-40 % zirconia to the cement paste. The effects of zirconia on setting time, strength and radiopacity were evaluated. In the in vivo study a 2 by 3.5 mm cylindrical defect in a rat vertebrae was filled wit...

Objectives/hypothesis: The main objective of this study was to investigate the effect of the administration of a novel immunoadjuvant, leukocyte interleukin injection, as part of an immuno-augmenting treatment regimen on the peritumoral and intratumoral subpopulations of the tumor infiltrating mononuclear cells and on the epithelial and stromal co...

To investigate the clinicopathologic effects of local neoadjuvant Leukocyte Interleukin Injection (LI) regimen in oral squamous cell carcinoma (OSCC) patients. Treatment regimen included LI 800 IU/d as interleukin-2 (IL-2), administered half peritumorally and half perilymphatically five times per week for 3 weeks; low-dose cyclophosphamide; indomet...

The most universal angiogenic cytokines (VEGF, bFGF, HGF) are all heparin-binding proteins, the function of which is dependent on cell surface heparan sulfate proteoglycans (HSPG). Several proteoglycans have been demonstrated in endothelial cells, but only glypican-1 from the cell surface HSPG subfamily was documented at protein level. Here, we sho...

Intratumoral vessels are different both structurally and phenotypically, and this may have clinical significance. In this study we analysed the expression of an adhesion molecule--vascular adhesion protein-1 (VAP-1)--in melanoma-associated blood vessels in 28 primary skin melanoma cases using immunocytochemistry and immunoelectron microscopy. We ha...

The cell adhesion molecule CD44 exists in multiple isoforms generated by alternative RNA splicing. Increased expression of CD44 isoforms containing exon v6 and v9 has been reported to be associated with the activated state of T lymphocytes. Using monoclonal antibodies against variant exon products we studied the expression of another variant exon,...

Twelve laryngeal squamous cell carcinoma cases (7 laryngeal and 5 hypopharyngeal cancer; 15 samples) were analysed by immunohistochemistry for the expression of invasion markers CD44v6/v3, NM23 and matrix metalloproteinase, MMP2. The laryngeal epithelium showed CD44v6+v3+NM23- /MMP2- phenotype. When tumors were grouped into TNM categories the pheno...
