Table 1 Histological reports for nine patients showing the macroscopic and microscopic findings, and the conclusion
PatientMacroscopyMicroscopyConclusionIs the tissue likely to be meniscal scar tissue?
1Cream tissueOrganised fibrous tissue and synovial surface. No atypical featuresAppearances likely represent fibrous synovial tissueNo
2Yellow and white tissueFragments of fibrous tissue partly lined by synovium show focal areas of denuded surface with acellular fibrinoid exudate. No significant inflammationFeatures in keeping with degenerate scar tissueNo
3Firm cream tissueFibrous tissue with focal degenerate area. No inflammation seenMeniscal tissueYes
4Firm cream tissueSections showing organised fibrous tissue and laminated pattern associated with foamy histiocytes at the periphery under the synovial surface. In areas the fibrous tissue lack nucleiAppearances likely represent meniscal remnants with degenerate featuresYes
5Firm cream tissueFragments of connective tissue. No features of atypia, malignancy, or significant inflammationConnective tissueNo
6Cream tissueFragments of fibrous tissue with overlying synovium. There is a mild inflammatory infiltrateFeatures in keeping with fibrous scar tissueNo
7Firm cream tissueSections show fragments of connective tissue. No evidence of atypia or malignancy. No significant inflammation is identified. There is a small collection of blood vessels seen in one edgeConnective/scar tissueNo
8Cream tissueFibro-collagenous tissue with synovial hyperplasia. Some degenerate hyalinised tissue that may represent cartilage, but the appearances are not specificFeatures in keeping with non-specific articular tissueMaybe
9Yellow and white tissueFibrous tissue with no significant inflammationDegenerate scar tissueNo
