Active clinical trials for "Joint Diseases"

The purpose of this study is to clarify the efficacy of a multidrug versus single drug periarticular injection when only standard operative and postoperative pain management protocols used and the control group is exposed to what our investigators believe is the standard of care, single medication periarticular injection

Hypothesis: Myofascial temporomandibular joint disorder and related symptoms are associated with mandibular condyle and temporal fossa overloading secondary to temporalis and masseter muscle hyperactivity and spasm This study will examine the use of onabotulinumtoxinA (Botox) to treat myofascial pain disorder in patients with bruxism who frequently exhibit signs of temporomandibular joint disorder (TMD) in a double blind cross-over randomized clinical trial by injecting 50 units Botox in temporalis and masseter muscles in 32 patients with 6 months follow up. The objective of the proposed study will be to establish the safety and efficacy of botox in treating TMD associated with bruxism. By the time patients reach the specialists office, most have failed maximal conservative therapies, including non-chew diet, night guard, oral analgesics, muscle relaxants, physical therapy, and a portion have even undergone more invasive procedures, such as manipulation under anesthesia, arthroscopy, and arthroplasty surgeries with limited improvement or recurrence. Primary outcome of the study will be 50% reduction in pain. Secondary outcomes will be 50% reduction in surgical therapy, 25% increase in maximal inter-incisal opening (MIO). The investigators look forward to working with you on the proposed study

To verify that CT scan and X-ray can predict the collapse of the necrotic femoral head before hip arthroplasty and effectively guide the surgical management.

The ultrasound-guided selective blockade of the saphenous nerve in the adductor canal provides effective analgesia and reduces postoperative pain in patients undergoing arthroscopic medial meniscectomy. Selective blockade of the saphenous nerve in the adductor canal provides effective analgesia without quadriceps muscle weakness. It has been shown that the adductor canal block (ACB) block increases the spread of local anesthetics in a distal and proximal way. Therefore, the proximal spread of local anesthetics may cause possible quadriceps weakness. The distal spread of local anesthetics may increase analgesic effect via sciatic nerve. The different volumes for ACB is a topic of discussion. The aim of this study is to compare the different volumes of US-guided ACB performing for postoperative analgesia management after total knee arthroplasty surgery.

In this prospective and randomized study, we aimed to compare the effect of of three sitting positions (the traditional sitting position (TSP), the harmstring stretch position (HSP), and the squatting position on the success rate of combined spinal epidural anesthesia in patients undergoing total knee arhtoplasty (TKA) or total hip arthroplasty (THA) surgery.

A total knee replacement is the removal of parts of the knee joint, that have become damaged due to osteoarthritis, and replacing these with artificial implants. The placement of these artificial implants and how they are aligned with each other is important because they can impact overall knee function and the long-term survival of the implant. It is reported that up to 34% of all patients following total knee replacement (TKR) have poor outcomes functionally. There have been significant developments in knee replacement surgery over recent years. In particular, the introduction of robotic surgical systems, such as the NAVIO and CORI systems (Smith+Nephew Plc). The NAVIO and CORI Surgical Systems are hand-held devices which can support the surgeon with the knee replacement procedure, the systems are image-free and do not require the patient to undergo any scans (such as CT scans). During the surgery, the surgeon uses the NAVIO/CORI hand-held device to map specific landmarks within the knee joint and determines the desired alignment using associated computer software. The tools to remove the bone and place the implants are controlled by the surgeon with the guidance of the NAVIO/CORI software. Comparisons of robotic systems to conventional instruments have demonstrated that robotic platforms produce fewer positioning errors in total knee replacement. This can result in more precise knee alignment and better outcomes following surgery. With both the NAVIO and CORI Surgical Systems there is a reduction in radiation exposure due to them being image-free. At present, there is some evidence available for the long-term outcomes of total knee replacement implanted using robotic assistance (i.e. 2-10 years) however this study is designed to look at the early outcomes following TKR. There is no literature to date to show that robotic-assisted TKR is superior to conventional methods, within the early post-operative period (up to 12 months). This study is designed to show that the NAVIO/CORI surgical systems are better than conventional methods for TKR. The hypothesis is that they will be cost-effective, will reduce the time a patient spends in hospital following their surgery, will improve patient satisfaction during the early recovery period and will improve the patient's early post-operative mobility and function.

Temporomandibular disorders (TMD) are characterized by pain and tenderness in the muscles of mastication and/or the temporomandibular joint (TMJ), limitations of jaw opening often accompanied by deviations in mandibular path, and clicking, popping or grating TMJ sounds. TMD is often found in association with other problems: depression, anxiety, sleep disturbances, gastrointestinal symptoms, frequent infections, etc. This project proposes to holistically address patient symptoms through three different approaches, Naturopathic Medicine (NM), Traditional Chinese Medicine (TCM), and usual care at KPNW. We will conduct a pilot test and Phase II trial to evaluate the two alternative healing approaches, TCM (n=50) and NM (n=50) delivered by TCM and NM practitioners, are as effective as usual TMD care (n=50) provided by dental clinicians in the KPNW TMD Clinic. Subjects will be females 25-55 years of age with multiple health problems (defined as patients who have had at least 4 organ system-grouped diagnoses in the past year, not including TMD). Subjects will be evaluated at baseline, 6 and 12 months after start of treatment. The primary endpoint is change from baseline in the Axis II Pain Related Disability and Psychological Status Scale. Clinical examinations, saliva samples to assess salivary cortisol levels, and responses to a series of questionnaires to assess pain, chronic pain, psychosocial functioning, and other physical symptoms will be used to assess outcomes. We will passively monitor health care utilization within KPNW using clinical, research, and administrative databases to determine whether the interventions have an impact on overall health care utilization. If either of these alternative interventions is shown to merit Phase III trial, our goal is to design and implement such a clinical trial to further evaluate the health consequences and costs of these alternative healing paradigms.

This is a prospective, multi-center, two-arm, randomized, controlled post-market study to evaluate and compare the clinical accuracy of component placement in robotic-assisted UKA and that of traditional methods.

The purpose of this study is to evaluate the diagnostic efficacy of Arthrex NanoScope compared to conventional arthroscopic instruments. Patients with wrist pathology who are indicated for an arthroscopic procedure will be enrolled pre-operatively after a thorough discussion of the study aims, risks, and benefits. At the time of surgery, under standard conditions, using standard wrist arthroscopy portals, a diagnostic arthroscopy will be performed with the Arthrex Nanoscope. The diagnostic arthroscopy will be performed in a stepwise manner for consistency with notation of pathology and intended intervention. The diagnostic arthroscopy will then be performed with the standard arthroscopic equipment, again noting pathology and final intervention. Post-operatively, diagnostic accuracy, incidence of change in intervention, and surgeon rated ease of use and confidence will be determined.

The purpose of this study is to evaluate the use and efficacy of the Iconacy Hip System for total hip replacement surgery.
