How long will my hip or knee replacement last?

For people considering hip or knee replacement surgery, it’s something they want — and need — to know. In the US alone, surgeons perform more than 600,000 knee replacements and about 330,000 hip replacements each year. These operations can provide a major improvement in quality of life and function for those with severe arthritis. On the other hand, there are risks associated with the operation (as is true for any major surgery), there is a long road to recovery even when all goes well, and these operations aren’t cheap. For knee replacement surgery alone, an estimated $9 billion or more is spent each year in the US (although economic analyses suggest the surgery may actually be cost-saving over the long run). So, if the first joint replacement is unsuccessful for some reason (such as infection or loosening), a second (or even third) operation may be necessary. And that’s a big deal, especially since “revision surgery” is technically more difficult, recovery can take longer, and success rates may be lower than first operations. There’s no hip or knee replacement guarantee Unfortunately, no one can be sure that a hip or knee replacement will be the last operation needed on that joint. No operation is 100% successful, and nothing lasts forever. In addition, a number of factors, including surgical technique and surgeon experience, how many operations a particular hospital or surgeon performs each year, and patient factors (includin...

Imagine you’re walking along and suddenly experience excruciating knee pain. Though it initially seems stuck in one position, after a minute or two you can limp along home, but just barely. At your doctor’s visit, an x-ray is normal but symptoms continue for weeks. An MRI is performed and now you have an explanation: a torn meniscus. (Two menisci — rubbery cartilage pads that act as shock absorbers — separate the bottom of your knee bone from the top of your shin bone.) A month later, you’re no better despite rest, pain medicines, and physical therapy. It’s time for surgery to fix it, ri...

​The wrist is not commonly aspirated in the emergency department, but emergent arthrocentesis may be indicated for extreme or concerning cases, and tapping the wrist to determine the underlying pathology or relieve pain may be of great value. The synovial fluid from the joint space can be analyzed for crystals, infection, and blood. This information may help determine the overall plan and aid in decision-making and consultation. The ultimate treatment plan may include admission, intravenous antibiotics, multiple aspirations, and even surgical washout.A swollen, painful wrist that is hot to the touch is concerning for sep...

BOSTON (CBS) – Many Americans with aching joints are offered steroid injections to help ease their pain, but local researchers say those shots are causing more harm. Steroid injections, often combined with a local anesthetic, are commonly used to treat hip and knee pain associated with osteoarthritis.  Researchers at the Boston University School of Medicine reviewed data on hundreds of joint injections performed in 2018 and found that, in some patients, those shots were associated with acceleration of the arthritis, fractures, and bone loss. The researchers say that, while more study is needed, radiologists and ...

Osteoarthritis (OA) is a common condition of the hip. Patients with hip OA often report nocturnal pain, yet little is known how it affects sleep quality. The purpose of this paper was to assess how hip arthritis affects sleep quality. We hypothesized that hip pain caused by hip OA affects sleep quality in adult patients. This is a prospective, cross-sectional study of patients who were diagnosed with hip OA. Patients were evaluated using Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), hip outcome score (HOS), and modified Harris hip score (mHHS). Sleep quality was assessed using Pittsburgh Sleep Qu...

Conclusion: These findings support the hypothesis that in FM a deteriorated function of cortical inhibition, indexed by a higher SICI parameter, a lower function of the DPMS, together with a higher level of BDNF indicate that FM has different pathological substrates from depression. They suggest that an up-regulation phenomenon of intracortical inhibitory networks associated with a disruption of the DPMS function occurs in FM. Introduction Major depressive disorder (MDD) and fibromyalgia (FM) present overlapped symptoms. Although the connection between these two disorders has not been elucidated yet, the disruption...

Conclusion: The present study suggests that the extract of LMZ attenuates CFA-induced inflammatory pain by suppressing the ERK1/2 and NF-κB signaling pathway at both peripheral and central level. Introduction Pain is one of the most common symptoms in clinical practice, and inflammatory pain is the most important type of pain (Patapoutian et al., 2009). Inflammatory pain is a growing global health problem. In generally, there is a common course of progression in inflammation and pain share. When patients experience inflammation, they may develop hyperalgesia or allodynia to various mechanical, thermal, or che...

Alex Bekker, Carolyn Kloepping, Shemille CollingwoodJournal of Anaesthesiology Clinical Pharmacology 2018 34(4):450-457 Oral formulations of meloxicam, a preferential cyclooxygenase-2 (COX-2) inhibitor, have long been used to treat osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, as well as various pain syndromes of skeletomuscular origin (e.g., low back pain). However, these preparations are rarely indicated for the treatment of acute pain due to a poor dissolution rate and consequently a slow onset of action. The recent introduction of an intravenous (IV) NanoCrystal Colloidal Dispersion formulation opens u...

ConclusionBoth the cocktail regimens are effective in pain control postoperatively. The relief in pain with regimen B containing bupivacaine, fentanyl, methylprednisolone and cefuroxime was more striking in the first 24 h. By the end of two days, both regimens were found to be equally effective.

​A bursa, a fluid-filled synovial sack, serves in the body as either a pulley or a cushion, and bursitis, of course, is an inflammatory response that can occur to a bursa. The causes of the inflammatory response can be trauma (direct or overuse), infection, or rheumatologic or crystal-induced disease.​Whether a bursa is deep or superficial ultimately determines the most likely pathophysiology and dictates the most appropriate treatment. Superficial bursae are those closest to the skin, and they are most vulnerable to direct trauma and infection—the prepatellar, infrapatellar, and olecranon bursae. Deep bursae inc...
