BioKnee 2-12 year outcome study

Meniscus transplant and articular cartilage repair

Stone K.R., Adelson W.S., Pelsis J.R., Walgenbach A.W., Turek T.J. 2010. "Long-term survival of concurrent meniscus allograft transplantation and articular cartilage repair: A PROSPECTIVE TWO- TO 12-YEAR FOLLOW-UP REPORT." J Bone Joint Surg Br 92-B(7): 941-948.

We describe 119 meniscal allograft transplantations performed concurrently with articular cartilage repair in 115 patients with severe articular cartilage damage. In all, 53 (46.1%) of the patients were over the age of 50 at the time of surgery. The mean follow-up was for 5.8 years (2 months to 12.3 years), with 25 procedures (20.1%) failing at a mean of 4.6 years (2 months to 10.4 years). Of these, 18 progressed to knee replacement at a mean of 5.1 years (1.3 to 10.4). The Kaplan-Meier estimated mean survival time for the whole series was 9.9 years (sd 0.4). Cox's proportional hazards model was used to assess the effect of covariates on survival, with age at the time of surgery (p = 0.026) and number of previous operations (p = 0.006) found to be significant. The survival of the transplant was not affected by gender, the severity of cartilage damage, axial alignment, the degree of narrowing of the joint space or medial versus lateral allograft transplantation. Patients experienced significant improvements at all periods of follow-up in subjective outcome measures of pain, activity and function (all p-values < 0.05), with the exception of the seven-year Tegner index score (p = 0.076).

A question I am asked a lot is, “I hear clicking and popping in my knee, is this something that I should be concerned about?”
Data everywhere, and nowhere to hide. In the bad old days, you got injured, and you didn’t tell anyone. You usually recovered. Lived to play another day. Until you couldn’t. Today, you get injured; you could be monitored, measured, uploaded and reported to everyone. You might not be allowed to play. You are “protected”, maybe even blacklisted. Which scenario is better?
If you want to be treated with a better than 75% chance of success—and if you value excellence as much as kindness—I suggest you demand that creativity be part of the doctor’s repertoire.
