Risk Factors Associated With Knee Joint Degeneration After Arthroscopic Reshaping for Juvenile Discoid Lateral Meniscus

Abstract

Smaller meniscal width and greater severity of meniscal extrusion correlated with knee joint degeneration. An anterocentral shift on preoperative MRI was a risk factor for degenerative changes and smaller residual meniscal width.

Examination of refractory discoid lateral meniscus injury

“…In terms of postoperative outcomes, in addition to subtotal meniscectomy, those with residual peripheral rim of 5 mm width or less and those that cannot maintain the hoop function of the meniscus have been reported to show predisposition to concurrent degenerative changes or OCD. 13,14 The merger rate of osteochondritis dissecans of the lateral femoral condyle (OCD) is highest in those with central shift as described by the Ahn classification. The remaining volume of the mid to posterior horn showed a negative correlation with OCD.…”

Ring-shaped meniscus formation may arise from the regenerative response to meniscectomy during growth spurts: A case report

“…These techniques were reported to have good clinical results [15,16]. However, reshaping cannot completely prevent degenerative changes, and smaller residual meniscal width and meniscal extrusion were significantly correlated with degenerative changes [17]. To prevent osteoarthritis progression after the reshaping, further studies are needed.…”

Arthroscopic minimum saucerization and inferior-leaf meniscectomy for a horizontal tear of a complete discoid lateral meniscus: Report of two cases

“…Furthermore, arthroscopic images showed little meniscal tissue was left compared to the present cases [ 10 ]. Recently, it was reported that residual meniscal width less than 5 mm was shown to be a risk factor for degeneration in treating DLM tears [ 19 ]. Additionally, after saucerization with peripheral repair for DLM tears, postoperative extrusion was observed from 2 weeks to 6 months after surgery [ 8 ].…”
