Descriptive statistics of 20 posterior cruciate ligaments in degenerative knees
| Patient | Age (years) | Sex (M/F) | Diagnosis | Preoperative destruction | Collagen fibre | Bone fragments | Neuro-filaments |
|---|---|---|---|---|---|---|---|
| Diagnosis: OA, osteoarthritis; RA, rheumatoid arthitis. | |||||||
| Preoperative destruction: classification according to Ahlback (OA) or Larsen (RA). In patients six and 13 a difference was present between the medial and lateral compartments. | |||||||
| Collagen fibres: mucoid degeneration (slight, focal, or extensive, see text) or normal aspect. Irregular or parallel collagen fibre orientation. | |||||||
| M, male; F, female. | |||||||
