Active clinical trials for "Osteoarthritis"

Despite improvements in analgesic treatment following total knee arthroplasty (TKA) for osteoarthrosis, a substantial part of patients still have severe acute pain after surgery. It has been suggested that preoperative degree of intraarticular inflammation is associated to postoperative degree of pain and level of function. Furthermore it is known, that patients with preoperative inflammation have hyperalgesia and severe movement related pain. The aim of this study is to investigate the effect of a preoperative intraarticular injection of Methylprednisoloneacetate in reducing acute postoperative pain after total knee arthroplasty in patients with signs of severe pre-operative inflammation and pain.

The objective of this study is to determine the most effective dose of Wobenzym® N versus placebo at reducing pain severity as measured by the WOMAC pain score in subjects with symptomatic knee osteoarthritis (OA) at 6 weeks of treatment.

The primary purpose of the current study is to investigate if the CONSERVE® A-Class Total Hip with BFH technology will lead to lower blood ion levels in patients, as compared to patients in a recent study who received the CONSERVE® Plus Total Resurfacing Hip System, another metal-on-metal device. We are also comparing functional and radiographic (x-rays) outcomes between patients who receive the CONSERVE® A-Class Total Hip compared to those who have received the CONSERVE® Plus Total Resurfacing Hip System.

The goal of this phase III study is to evaluate the efficacy, safety, and tolerability of chondroitin sulfate 800 mg oral tablets versus placebo in the treatment of subjects with pain due to knee OA (osteoarthritis). The further aims of the study are to evaluate the durability of the treatment effect (up to week 36) and to gain further long-term safety and efficacy data (up to 48 weeks). The primary outcome of interest will be the effect of chondroitin sulfate on pain in the index knee at week 24 compared to placebo. The effect of chondroitin sulfate in the index knee functionality and the patient global impression of changes at 24 weeks compared to placebo are included as key-secondary endpoints. An additional key secondary endpoint will assess the durability of the effect on pain compared to placebo at week 36. Several additional secondary endpoints are included to further support the beneficial effect of the treatment and the improvements in patient's quality of life (i.e., Western Ontario and McMaster Universities Arthritis Index -WOMAC- subscales and total scores at each study visits, changes in patient's quality of life, use of rescue medication etc.) other than the safety of the product.

In this study the investigators aim to examine the effects of Transcranial Magnetic Stimulation (TMS) on hippocampal network connectivity and pain levels in individuals with pain due to knee osteoarthritis.

The purpose of the study is to evaluate the efficacy of local infiltration of liposomal bupivacaine versus use of an indwelling femoral peripheral nerve block in controlling early postoperative pain in primary total knee arthroplasty. The investigators hope to demonstrate equivalency of treatment modalities to provide an alternative to the commonly used treatment of femoral nerve blockade.

This randomized clinical trial will evaluate the efficacy of an antiresorptive osteoporosis drug (denosumab) in prevention of periprosthetic bone loss and in promotion of implant osseointegration (bone bonding) in postmenopausal women after total hip replacement. The investigators assume that denosumab prevents periprosthetic bone loss and enhances bone bonding of the hip stem in postmenopausal women.

Osteoarthritis is a common joint disorder in the elder population.The current treatment options include both a non-pharmacological approach (physiokinesitherapy, diet) or if this fails, a pharmacological approach that relies in the first instance on drugs such as paracetamol, non-steroidal anti-inflammatory (including inhibitors of cyclo-oxygenase). However, the use of these drugs is limited, by the roof effect concerning analgesia, and by the potential side effects. When pharmacological treatments with non-opioid medications fail, and a moderate-to-severe pain reduces the quality of life of the patient, international guidelines suggest the use of opioid drugs.

The primary objective of the study is to assess analgesic efficacy of Impracor (Ketoprofen 10% Cream) compared to placebo for acute pain associated with OA flare of the knee.

In this trial different parts of the pain signalling system involved in two rheumatic diseases - painful hand osteoarthritis and psoriatic arthritis, is examined. These measurements will be compared to those of healthy volunteers The hypothesis is that patients with hand osteoarthritis and psoriatic arthritis react differently to painful and non-painful stimuli compared with the healthy volunteers. The aim is to recruit 66 patients with painful hand-osteoarthritis, 66 patients with painful psoriatic arthritis and 66 healthy subjects not currently suffering from any pain conditions. After completing an informed consent form subjects will participate in a single clinical visit. The pain signalling system is examined using pressure algometry and cuff algometry. A pressure algometer is a pistol shaped device that elicits pressure through a rod and a cuff algometer is akin to a blood pressure cuff. Different thresholds will be measured, such as when the sensation of pressure becomes painful and when the painful pressure becomes unbearable. Participants will also get hand strength tested, have their joints examined and answer questionnaires regarding daily function and quality of life. Furthermore participants will get blood drawn which is analysed for the presence of markers of inflammation and joint degeneration.
