Filter by:Two injections in total and 3 ml autologous adipose-tissue-derived stem cells(haMSCs) for each injection; time-points for intervention: 1) initial injection; 2) 3 weeks following initial injection.
It is a double-blind randomized sham-controlled clinical trial to evaluate the effectiveness of resistive capacitive diathermy in subjects affected by knee osteoarthritis in comparison with a "sham" diathermy treatment. The resistive capacitive diathermy is a medical device supplying low (448 KHz) radiofrequencies with maximum output power of 200 W, used to reduce pain and inflammation and allowing healing processes. The sham diathermy treatment is administered with the device set on "on" but not active (not supplying energy). Each subject, randomly assigned to either resistive capacitive diathermy treatment (group 1) or sham-treatment (group 2) is submitted to a thirty minutes session, three times per week for a total of ten sessions. The outcome measures are the WOMAC scale (Western Ontario and McMaster Universities Arthritis Index) to assess pain and physical functioning, a visual analogic scale (VAS) for pain, the femoral quadriceps strength (MRC = Medical Research Council Scale). Outcome measures are administered at baseline (T0), at the end of the treatment protocol (T1), at 1 month (T2) and 3 months (T3) after the end of treatment.
Knee osteoarthritis (OA) is now recognized as a major health problem. It is the number one cause of lower extremity disability and has significant deleterious effects on quality of life. While there are numerous therapies available for knee OA, most have limited efficacy. Of particular concern, is the widespread use of nonsteroidal anti-inflammatory drugs (NSAIDs) for this disorder. Veterans, as a group, are at high risk for both gastrointestinal and cardiovascular NSAID-induced complications. In this study the investigators propose to examine whether replacing NSAIDs with cognitive behavioral therapy delivered by telephone is an effective strategy for Veterans with knee OA. Telephone-administered therapy is particularly appealing since Veterans with knee OA are more likely to have limited mobility. If successful, this program may result in significant cost-savings for both Veterans (decreased co-pays and transportation costs) and the VA (decreased hospitalizations due to NSAID induced toxicity).
The purpose of this study is to test whether the platelet-rich plasma (PRP) intra-articular injection therapy is effective as an alternative treatment option in patients with mild knee osteoarthritis within a controlled randomized study compared to first line treatment acetaminophen. The investigators will evaluate patients outcome in level of pain, knee function and quality of life before the treatment and at 6, 12 and 24 weeks follow up. The study will be complemented with in vitro experiments of human osteoarthritic cartilage explants culture (treated with PRP) for histological and gene expression assays. PRP intra-articular injections therapy is effective in patients with mild knee osteoarthritis by modifying the biochemical joint environment and cartilage regeneration capability.
This prospective single-center study will evaluate the safety and tolerability of a single dose of "APS(TM)" treated patients with OA of the knee who have failed conservative OA therapy. The study will also evaluate efficacy by assessing patient pain and functionality.
This clinical trial is planned to prove Entelon tab. arm is not inferior to Celebrex cap. arm in terms of the efficacy and safety through the change of K-WOMAC's total score sum in patients with osteoarthritis of knee.
The primary objective of this study is to identify osteoarthritis (OA) structural changes, as assessed by MRI, that best correlate with the presence of neuropathic pain (NP) using the PainDETECT questionnaire (PainDETECT ≥ 13) on a population of patients with OA of the knee experiencing moderate to severe pain (VAS ≥ 40 mm).
Background: In the early phase after a total knee arthroplasty (TKA), patients experience multi-level weakness in the operated leg, which is caused primarily by reduced central nervous system (CNS) activation failure of the muscles - especially the knee extensors. This considerable loss of muscle strength relates to reduced functional performance. Early-commenced, progressive strength training of the knee extensors of the operated leg therefore seems rational. However, the concern is that this type of early-commenced, intense physical rehabilitation exacerbates post-operative symptoms, such as knee joint pain. The investigators have recently reported that early-commenced physical rehabilitation, including progressive strength training of the knee extensors of the operated leg seems feasible after TKA. The classic exercise-physiology literature emphasizes loading and repetitions performed to contraction failure - among others - as important variables for muscle hypertrophy and strength gains. It is currently not known how loading and repetitions performed to contraction failure during knee extensions with the operated leg, influences post-operative knee joint pain in patients with TKA. Purpose and hypothesis: The purpose of this study is to investigate how loading and repetitions to contraction failure influence knee joint pain during knee extensions with the operated leg early after TKA. The hypothesis is that knee pain increases with increasing loading and fatigue. Methods: Fifteen patients with a unilateral TKA, operated between 1 to 2 weeks prior to the first investigation, will be included. The participants are investigated twice. During the first investigation, the absolute load (kilograms) corresponding to 10 Repetition Maximum (RM) (a load that can be lifted exactly 10 times) will be determined for unilateral (operated leg) knee extension. At the second investigation, at least 72 hours later, the patients will perform 1 set of 4 repetitions with a relative loading of 8, 14, and 20 RM each, in a randomized order, estimated from their 10 RM test at the first investigation. Time under tension (contraction velocity) and range of knee joint motion for each repetition will be controlled for. During the concentric phase of each repetition, the patients rate their knee joint pain verbally, using a numerical rating scale placed 1 meter in front of them. After a short break, the patients perform 1 set of knee extension with a relative loading of 10 RM until of contraction failure. As for the loading effect described above, they rate their knee joint pain during the concentric phase of each repetition.
The purpose of this study is to determine whether a standardized education and exercise program proposed before a total knee replacement for knee osteoarthritis is effective in functional recovery after surgery.
Knee osteoarthritis (OA) can result in significant pain and limitation of function. A number of topical non-steroidal anti-inflammatory drugs have been shown to reduce pain in this condition. This study examines a different topical approach, utilizing a topical anesthetic agent, to evaluate if application of such an agent would provide relief of exercise-induced knee pain in people with knee OA.
