53. Joint position sense in the knee before and after partial meniscectomy

A Transplant or a Patch? A Review of the Biologic Integration of Meniscus Allograft Transplantation

“…At 6 months postoperatively, collective position sense had again improved in the transplanted knee 24 . However, the results of this study were insignificant (p 5 0.074) 24 , and the pattern of change does agree with previous literature 23 , indicating that a meniscus transplant can restore some proprioceptive function compared with a meniscectomy or partial meniscectomy which as explained above have demonstrated a decrease in proprioception after surgery [20][21][22] . This is not to say that the absolute proprioception in MAT Fig.…”

“…It also appears, along with vascularization, that there is at least some reinnervation occurring after transplantation as well. Loss of proprioception after partial meniscectomy is one driving force behind dissatisfaction after the procedure 20,21 . MAT, however, in contrast appears to be able to improve sensation and proprioceptive function 23,24 .…”

“…It has been shown that there are significant mechanoreceptors and nociceptor endings, primarily in the anterior and posterior horn but in the meniscus body, that mimic the vascular distribution 18,19 . The innervation of the meniscus and subsequent destruction during partial meniscectomy is one potential reason it has been shown that some proprioception is lost after partial meniscectomy [20][21][22] . Patients report decreased proprioception compared with even the torn preoperative state after partial meniscectomy.…”
