Complications following hip or knee surgery are more likely for people with long-term illness, but benefits are still worthwhile
People with long-term illness are just as likely to benefit from knee or hip surgery as those without. However, they are more likely to have complications following surgery and to be readmitted within three months.
This study reviewed data from 70 studies to determine the chance of short-term harms and long-term benefits linked to 11 different co-existing health conditions (such as diabetes and cancer) following hip and knee replacement. Short-term outcomes included surgical complications, infe...
Partial knee replacements may save costs compared with total knee replacements
Partial knee replacements, when performed by experienced surgeons, can save costs and improve quality of life compared with total knee replacements. Partial replacements for selected patients improve quality of life and savebetween £600 and £2,000 over the patient’s lifetime, depending on age and gender.
Knee replacements are commonly performed for people with ongoing pain and poor function. If the damage is limited to one side of the knee, it may be suitable to replace just t...
Joint infection after hip replacement is linked to some risk factors that could be modified
Ten years of National Joint Registry data show that many factors may increase the risk of joint infection following hip replacement. Less than 1 in 1,000 people on average needed revision surgery for infection per year.
Several modifiable patient factors increased risk, such as obesity and diabetes. Using ceramic components, and approaching surgery from the back rather than the side of the hip, may slightly reduce infection risk.
This NIHR-funded study analysed registry data for 623,253 hip re...
Negative pressure dressings are no better than standard dressings for open fractures
Negative pressure wound dressings are neither more nor less effective than standard wound dressings for severe open fractures of the lower leg. Any difference between groups was neither clinically important nor statistically significant. The outcomes included self-rated disability at one year, quality of life and deep surgical site infections at one month which occurred in around 7-8% in each group.
Open fractures of the leg, where the broken bone is exposed by the original injury or has burst ...
Keyhole surgery is more effective than physiotherapy for hip impingement
Keyhole surgery to reshape the joint surfaces in people with hip impingement improves hip-related quality of life more than physiotherapy.
In hip impingement, there is a painful restriction of the smooth movement of the ball of the femur inside the cup (acetabulum) of the pelvis. It mainly affects younger, active people. Observational studies have supported the use of keyhole surgery (arthroscopy), but there was a lack of high-quality evidence. This NIHR-funded study is the first trial to compa...
People with osteoarthritis can benefit from exercise but may harbour myths about safety
Programmes that show people with osteoarthritis how to exercise safely may slightly improve pain scores, self-belief and social function, but participants also report the myth that discomfort while exercising indicates on-going harm.
The review combines evidence from 21 randomised controlled trials evaluating exercise in hip or knee osteoarthritis with 12 studies where people receiving the intervention were interviewed about the impact of exercise on their disease. Participants were men and wom...
Aspirin may be a follow-on option to prevent blood clots, starting five days after hip or knee surgery
In a recent trial, switching to low-dose aspirin was just as effective at preventing blood clots after joint replacement surgery as continuing the anti-clotting drug rivaroxaban. Six per 1,000 people taking aspirin experienced a blood clot, compared with seven per 1,000 taking rivaroxaban. Three to five per 1,000 patients experienced major bleeding with either drug.
Rivaroxaban or similar drugs are usually prescribed for two or five weeks after knee or hip surgery, respectively, to reduce the r...
Hospital admission rates and costs increase in line with BMI
Each 2kg/m2 rise in body mass index (BMI) above the normal-weight threshold in women aged 55-79 leads to a 5% rise in annual hospital admissions and 7% rise in healthcare costs. In England, £662 million of the annual hospital admission costs in 2013 could be attributed to overweight or obesity in women of this age group.
This large study, partly funded by the NIHR, looked at over one million women participating in the NHS breast cancer screening programme. Five-year data on hospital admis...
A surgical procedure for shoulder pain is less effective than previously thought
An increasingly common surgical procedure for shoulder pain, subacromial decompression, was only slightly more effective than no treatment. In the first trial of this sort, improvements in pain and function following decompression or arthroscopy (a placebo surgery) did not reach a threshold of clinical importance compared with people allocated to no treatment at all.
This NIHR-funded study involved 313 people with shoulder pain that had not responded to physiotherapy and a steroid injection. Th...
Two common operations to fix a broken tibia have similar outcomes
In people who had broken the lower part of their tibia (shin bone), fixation using a metal rod nailed to the insideof the bone was compared with a locking plate screwed onto the surface of the bone. There was no difference in the quality of life, disability or pain at 12 months for people who had fractures of the lower tibia fixed using either technique.
NICE guidance recommends that surgery takes place within 24 hours of injury but does not mandate which type of surgery to perform. This NIHR U...
