Arthroscopic Surgery for Degenerative Meniscus Tears Increases Risk of Total Knee Replacement


Your orthopedic surgeon wants to do arthroscopic surgery for your meniscus… better watch out!

Arthroscopic surgery for degenerative meniscus tears increases risk for eventual knee replacement

A recent study published in the journal Osteoarthritis Cartilage showed that patients with osteoarthritis of the knee who undergo arthroscopic surgery for degenerative meniscus tears are at markedly increased risk for potentially having total joint replacement. In the study, 335 patients with osteoarthritis of the knee underwent arthroscopic surgery for degenerative meniscus tears. They were followed for two years.

The authors demonstrated that in patients with knee osteoarthritis, arthroscopic knee surgery with meniscectomy is associated with a 3 fold increase in the risk for future knee replacement surgery.

Comment: Don’t do it if you can avoid it. The meniscus serves of function. It helps to cushion the knee. Any meniscus tissue should be preserved.

Degenerative Meniscus Tears Rarely Require Surgery


And your surgeon says you need surgery… maybe not… next

Meniscal Tears May Not Need Surgery

Jack Cush reporting in RheumNow cited a study published in the British Medical Journal examines whether knee surgery or conservative medical management benefits those with degenerative meniscal tears. Patients with knee pain from a degenerative meniscal tear were randomized to either arthroscopic surgery (followed by daily exercises at home) or physical therapy (neuromuscular and strength exercises) two to three times a week for 12 weeks.

Over the next 2 years both groups improved. Muscle strength had improved more, on average, in the physical therapy group at the three-month checkup, but at the final two-year checkup, there was essentially no difference between the surgery and therapy groups, including in pain, ability to function in sports and recreation activities, and quality of life. The researchers noted that 19 percent of the therapy group opted to have surgery at some point but had achieved “no additional benefit” by the end of the study.

Conservative exercise therapy was equal to arthroscopic intervention overall, but also showed positive effects over surgery short-term muscle strength.  Clinicians should consider conservative management and physical therapy in middle-aged patients with degenerative meniscal tears.

Comment: Degenerative meniscus tears are secondary to the arthritis. Surgery is not generally warranted.

Nose Cartilage Helps Knee Osteoarthritis

Aching Knee? Surgeons Pioneer Groundbreaking New Operation Taking Tissue From The NOSE To Grow Cartilage That May Be Due To Osteoarthritis!

Roger Dobson writing for the Daily Mail reported surgeons are taking tissue from the nose to grow cartilage to fix knee-joint pain.
The operation sees cartilage harvested from the nose, which is then used to grow patches of tissue to be transplanted on to knee joints.

The procedure is regarded as particularly beneficial for osteoarthritis patients, or those at risk of the joint disease, and doctors carrying out the operation say it could help thousands of people.

The most widely used procedure to repair the injury involves trimming any remaining damaged tissue and drilling holes in the bone beneath the defect to trigger bleeding and scar tissue that, it is hoped, can work as a substitute tissue.

But according to the NHS, results are variable, with studies suggesting that it offers only short-term benefits and does not lead to the formation of new cartilage.

Comment: The procedure is a bit risky for only short term relief but maybe it will improve.

Stem Cells for Hip Osteoarthritis


Hope for young people with bad osteoarthritis of the hips… next

Stem Cells Could Replace Hip Replacements

Christopher Wanjek writing for Live science reported scientists have coaxed stem cells to grow new cartilage on a scaffold shaped like the ball of a hip joint. This is a major step toward being able one day to use a patient’s own cells to repair a damaged joint, thus avoiding the need for extensive joint-replacement surgery.

In addition, the scientists used gene therapy to grant this new cartilage the ability to release anti-inflammatory molecules when needed. If done in patients, this technique could help prevent a return of arthritis, if that was what damaged the joint in the first place.

The new technique may be ready to test in humans within three to five years and may ultimately work with other joints, such as knees, said Farshid Guilak, a professor of orthopedic surgery at Washington University School of Medicine in St. Louis, who co-led the project.

Comment: We stopped doing stem cell procedures for hips at our center because we weren’t getting the results we wanted. While this approach looks like it might work I’m reserving judgement. The hip has a unique mechanical structure that makes any type of stem cell procedure problematic..

Pain Predictor of Knee Osteoarthritis


Are there early warning signs of knee arthritis? Yup!

Persistent knee pain predicts structural arthritis early.

Sara Freeman writing in Rheumatology news reported on a study that showed that persistent knee pain is in important predictor of structural joint damage and could potentially be used to predict knee osteoarthritis earlier according to Dutch research reported at the World Congress on Osteoarthritis. The analysis found that women participating in the Rotterdam study who had knee pain on most days of the preceding month were more than 4 times more likely to develop knee osteoarthritis within 5 years on MRI than were those without frequent knee pain.

Comment: a key finding.
