Meniscus Healing

Aims and Objectives: The purpose of the study was to prospectively investigate signal alterations in short-term follow-up after acute meniscus repair on specific magnetic resonance imaging (MRI) scan sequences. It was hypothesized that 1) there are different meniscus healing properties depending on lesion configuration and size, and 2) the tear zone has an influence on the healing properties of the meniscus. Materials and Methods: We conducted this prospective short-term clinical and radiological study to investigate the healing properties of acute meniscus tears. Inclusion criteria were patients (age 18-45 years) with traumatic meniscus lesion, subsequent arthroscopic meniscus repair within 6 weeks and preoperative MRI. Exclusion criteria were age < 18 or >45 years, arthrosis > grade III and multiligamentous knee injuries. Clinical examination and outcome scores (IKDC, KOOS, Lysholm Score) were surveyed preoperatively and 12 weeks after surgery. Meniscus tears were classified according to the ISAKOS meniscus classification system on MRI scans. Radiological assessment using a 3T-MRI was performed preoperatively and 2, 4, 6 and 12 weeks after operation. Meniscus healing were classified according to Henning’s criteria in A) healed, B) partially healed (> 50%) and C) not healed. Data were analyzed using SPSS statistics software version 21 (IBM, New York, USA). Statistical significance was set at a p value of < 0.05. Results: These are preliminary results of 14 patients (13 m, 1w) with a total of 16 meniscus tears. According to the ISAKOS meniscus classification system 9 medial and 7 lateral meniscus tears were included and average tear length was 21.5 mm (6 - 40 mm). 12 tears were located in the rim zone 1 and 4 tears were more medially in zone 2. In 8 (57%) patients an additional anterior cruciate ligament (ACL) reconstruction was performed. Six weeks postoperatively 8 menisci (50%) were deemed healed, 6 menisci (37%) partially healed whereas 2 menisci were not healed (13%). After 12 weeks 9 menisci (56%) were considered healed, 4 menisci (25%) partially healed and 3 menisci (19%) showed intrameniscal joint fluid in more than 50% of meniscus thickness. Two bucket handle tears of the medial meniscus and one radial tear of the lateral meniscus, all located in the red-red zone sized 35 mm, 25 mm and 12 mm, were not healed after 12 weeks. Clinical scores improved significantly 12 weeks after surgery: IKDC Score (preOP: 46.7, postOP: 67.8), KOOS (preOP: 49.7, postOP: 79.1) and Lysholm Score (preOP: 49.5, postOP: 77.7) (p < 0.05). Conclusion: Clinical and radiological follow-up showed good short-term results after meniscus repair. MRI revealed signal alteration in all menisci after 12 weeks, in most instances considered as scar tissue without intrameniscal joint fluid. In this cohohrt tear size and location was not correlated with non-healing. Arthroscopic meniscus repair achieves a high healing response of the meniscus and good clinical outcomes.

The Mean

Background: Lateral discoid meniscus (LDM) should be treated and preserved with saucerization and/or suture repair. However, repair of the meniscal hoop structure is sometimes difficult due to displacement or large defects. In this study, we aimed to examine tear patterns based on the Ahn classification in those requiring meniscal repair and those undergoing subtotal meniscectomy. Methods: Twenty-three patients were evaluated (mean age, 27.4 years; mean follow-up period, 2.5 years). The following were evaluated: displacement morphology based on the Ahn classification, site of tear under arthroscopy, morphology, surgical procedure, Lysholm score at final postoperative follow-up, and clinical outcome of meniscus using Barrett’s criteria. Result: There were 16 knees without displacement (saucerization with suture repair, 13 knees; subtotal meniscectomy, 3 knees) and 10 knees with displacement (reduction with suture repair, 3 knees; subtotal meniscectomy, 7 knees). Subtotal meniscectomy was performed more often in cases with dislocation, especially in the central shift type as defined by the Ahn classification. The mean Lysholm score was 65.0 points preoperatively and 95.3 points postoperatively. Twenty-three knees (88%) were postoperatively categorized under the Barrett’s criteria as healing and 3 knees (12%) were categorized as non-healing. The number of non-healing cases that underwent subtotal meniscectomy was relatively small (1 of 10 knees), and the short-term results were not poor. Conclusion: Localized peripheral longitudinal tears tended to be repairable even with displacement, while peripheral tears covering the entire meniscus or with severe defects/tears in the body of the meniscus tended to be difficult to repair, leading to subtotal meniscectomy.

Ring Type

The discoid meniscus is the most common meniscal variant. The likely etiology being congenital, the condition usually affects the lateral meniscus. Poorly vascularized, thicker and unstable, the discoid lateral meniscus (DLM) is more prone to tears due to abnormal shearing forces. Watanabe et al. (1979) classified the discoid lateral meniscus into three types: Complete, incomplete and Wrisberg type; Monllau et al. (1998) added the ring type as the fourth variant. Pain and clicks/thud are the most common presentations. Plain radiograph and magnetic resonance imaging are helpful in confirming the diagnosis. Asymptomatic DLM is best left alone. For symptomatic complete and incomplete types, partial arthroscopic saucerization is the treatment of choice leaving behind a stable rim. The Wrisberg type needs peripheral stabilization with resection of excess rim, if any. Total meniscectomy should be avoided unless inevitable. Short term results after partial meniscectomy are good.
