As you can guess, my focus has transitioned slightly from this blog over the last few months to some external projects and case reports. I apologize for the lull in content – although not to worry – the sprint-like pace is returning. Thus the need to catch up on some friendly reading, and ski a few more times to stress my meniscal limits. Fortunately, coming up in mid January I jump back onto lower extremity disorders. Yes, I have had a cancel today and catching up on the blog world some interesting trends are: empathy, and meniscal research seems to have some heat behind it. In preparation for the upcoming coursework – why not empathetically talk about the meniscus.

Meniscus – I know how you feel, it’s the holidays – we have all taken a beating. I apologize that the extra 45 cookies I ate probably placed increased pressure on your already strained life. Empathy is a fantastic topic, but has been re-capped very well by the following blog: http://abetternhs.wordpress.com/2013/12/20/empathy/. I will leave that up to them, and we can chat a few common questions with recent literature in regards to the meniscus. This ones gong to be quick folks – and keep in mind – a few cancellations is not enough time for a full literature review.

What are the outcomes of a meniscal tear or repair?  

  • REPAIR OUTCOMES: Pujol et al (10 month follow up)1
    • IKDC scores good in 92% cases
    • 23 patients no signs of OA at 10 months
    • Initial healing rates did not significantly influence outcomes
    • 60% of patients demonstrated complete healing
    • 25% of partial healing
    • 15% of failure, only 12% required follow up menisectomy
  • REPAIR OUTCOMES: Lyman et al:2
    • 8.9% frequency of subsequent meniscectomies at a median follow-up of 3 years after meniscal repair
  • CONSERVATIVE OUTCOMES
    • Rathleff et al: 58% were treated successfully by conservative treatment.

Best post-operative protocol for meniscal repair?

 

  • Nielsen et al:1
    • The following two protocols were compared:

    • No STATISTICAL difference noted in repair failure rates. Although, noted that at 1 year follow up 7% failure in free rehabilitation and 25% failure in restricted rehabilitation and at 2 year rates were 28 and 36% respectively.
    • No statistical difference in KOOS scores

Is there any literature to state if I don’t get the menisectomy, that it will get worse?

 

  • To the contrary….
    • Cohen et al: There was significantly greater cartilage loss in patients post-meniscectomy at follow-up than in those who did not have meniscectomy. Cartilage loss was observed in 38% compared with 76% in patients with meniscectomy. 
    • To my knowledge no study discusses that if we don’t resect or repair the tissue that the tear worsens over time, intuitively this may make sense and may take a stab at this above statement.
