This study analysed the differences on a molecular level between two segments of the deep flexor tendon, and compared the intrasynovial flexor tendon with the tendon sheath and the extrasynovial peroneus tendon in a rabbit model. The TRIspin method of RNA extraction was combined with the reverse transcription polymerase chain reaction to assess mRNA levels(More)
BACKGROUND AND PURPOSE The Artelon CMC spacer is designed for surgical treatment of osteoarthritis (OA) in the carpometacarpal joint of the thumb (CMC-I). Good results using this degradable device were previously presented in a pilot study. We now present results from a larger randomized, controlled, multicenter study. PATIENTS AND METHODS 109 patients(More)
The purpose of this study was to compare the levels of procollagen type I messenger RNA (mRNA) in normal and healing medial collateral ligament (MCL) and anterior cruciate ligament (ACL) in a rabbit model. Our method of injury involved a surgical model with identical partial lacerations in the midsubstance of the MCL and ACL. Paraffin sections of normal(More)
A total of 397 hips were randomised to receive Metasul metal-on-metal (MoM), metal-on-conventional polyethylene (MoP) or ceramic-on-polyethylene (CoP) bearings using a cemented triple-tapered polished femoral component (MS-30). There were 129 MoM hips in 123 patients (39 male and 84 female, mean age 63.3 years (40.7 to 72.9)), 137 MoP hips in 127 patients(More)
This study assesses the effect of a preparation of hyaluronan (hyaluronic acid) applied topically at the time of flexor tendon repair in a well-established model. The hypothesis is that hyaluronic acid applied topically at the time of flexor tendon repair will decrease adhesions, and will improve clinically the gliding function of the repaired flexor(More)
Using a rabbit model of flexor tendon injury, mRNA levels for a subset of relevant molecules involved in inflammatory and fibrotic processes were assessed by reverse transcriptase-polymerase chain reaction 3, 6, 12 and 24 days after injury. Increased levels of COX-2, IL-1beta, MMP-13 and TIMP-1 mRNA were detected in both tendon and tendon sheath following(More)
The purpose of the study was to contribute to the mapping of molecular events during flexor tendon healing, in particular the growth factors insulin-like growth factor-1 (IGF-1), vascular endothelial growth factor (VEGF) and nerve growth factor (NGF), matrix metalloproteinases (MMP-3 and MMP-13) and their inhibitors (tissue inhibitors of metalloproteinases,(More)
The purpose of this study was to assess, morphologically and biochemically, the effect of hyaluronan (HA) on the early repair process of the anterior cruciate ligament (ACL). Following partial bilateral laceration in the midsubstance of the cruciate ligament, a single dose of HA (MW of 3.6 x 10(6] was injected in one knee and saline in the contralateral(More)
BACKGROUND Postoperative adhesions constitute a substantial clinical problem in hand surgery. Fexor tendon injury and repair result in adhesion formation around the tendon, which restricts the gliding function of the tendon, leading to decreased digit mobility and impaired hand recovery. This study evaluated the efficacy and safety of the peptide PXL01 in(More)
PURPOSE Injuries to tendons, particularly flexor tendons, can lead to loss of function after healing due to adhesion formation and other complications. The aim of this study was to increase our understanding of the healing process in tendons and tendon sheaths to develop methods to affect the healing process and improve the outcome of tendon repair in the(More)
