Analysis of short and long-term results of horizontal meniscal tears in young adults

AbstractIntroductionSymptomatic horizontal meniscal tears are rare but worrisome lesions in young adults. These are overuse injuries not amenable to the classic arthroscopic sutures. An open meniscal repair allows the meniscal lesion to be suture vertically, perpendicular to its in the vascularized zone. The purpose of this study was to evaluate the short and long-term clinical and radiological outcomes of the aforementioned surgical technique.Material and methodThe first cohort consisted of 24 patients operated between 2009 and 2011 (6 women, 18 men; mean age 26years) having 11 lateral and 13 medial meniscal tears. The second cohort was of 10 patients operated between 2001 and 2002 (3 women, 7 men; mean age 24years) having 8 lateral and 2 medial meniscal tears. Patients were reviewed at the last follow-up using the IKDC, Lysholm and KOOS scores. Patients in the first cohort had an MRI, while those in the second cohort had X-rays.ResultsEighteen patients in the first cohort were reviewed with a mean follow-up of 2years (12–45months) and 9 patients from the second cohort were reviewed after 10years (97–142months). In the first cohort, one patient required secondary menisectomy. The mean Lysholm score was 90 and the subjective IKDC was 85. Every MRI examination found reduced extent and intensity of the hyperintense signal. In the second cohort, no patients required secondary meniscectomy. Two patients had joint space narrowing (less than 50%) on radiographs. The mean Lysholm score was 99 and the subjective IKDC was 91.ConclusionOpen repair of horizontal meniscal tears in young adults leads to good subjective and objective results in the short term, which are maintained in the long-term.Level of evidenceLevel IV – retrospective study

Painful medial knee compartment syndrome in over-45 year-olds: I – Medical or surgical management: a series of 174 patients

SummaryIntroductionThere is at present no consensus on the management of degenerative medial meniscus lesions in patients aged over 45 years without proven osteoarthritis, especially given that the causal relation between degenerative meniscal lesion and osteoarthritis remains controversial. A prospective multicenter non randomized study was therefore performed. The principal objective was to assess surgeons’ practice in the management of degenerative medial meniscus lesions. The secondary objectives were to identify predictive and prognostic factors and to compare medical versus surgical attitudes so as to draw up an adapted treatment strategy.Patients and methodOne hundred and seventy-four patients were included between September 2008 and February 2010, and distributed between a surgical (n=104) and a medical group (n=70). Minimum follow-up was 6 months. Patient satisfaction and health-related quality of life on the SF-36 questionnaire were assessed at 6 months.ResultsNo difference emerged between the surgical and medical groups. However, predictive factors for poor results were identified: overweight (p=0.005), cartilage lesions (p=0.035) and meniscus extrusion (p=0.006).DiscussionResults clarified the relation between degenerative meniscus lesions and osteoarthritis, in terms of meniscal incompetence. Meniscal extrusion should be seen as an arthrogenic degenerative meniscus lesion. We recommend a management strategy based on terrain and imaging data (X-ray and MRI), with the aim of providing patient relief while conserving cartilage
