Rice bodies of synovial origin in the knee joint.

Rice bodies are free corpuscles of synovial origin with a cartilage-like appearance that may reach hundreds in number in the intra-articular space. Rheumatologic or infectious pathologies that may produce synovial hypertrophy play a major role in the etiology. Already recognized by rheumatologists, this entity is rarely reported in orthopaedic literature. Numerous particles in the size and form of rice bodies were noted in the knee joint of an 11-year-old patient who underwent arthroscopic drainage and partial synovectomy. Histopathologic examination showed that some of the rice bodies consisted only of fibrin and some of them included a collagenous nucleus surrounded by a fibrin layer. No evidence of recurrence was observed by orthopaedic and rheumatologic evaluations within 2.5 years after the arthroscopic procedure.

Localized pigmented villonodular synovitis of the knee.

Localized pigmented villonodular synovitis (PVNS) of the knee is a rare, idiopathic condition presenting with symptoms that can be confused with various other intra-articular pathologies. The condition is usually monoarticular, the knee being most commonly affected. If totally excised, complete cure can be achieved and recurrence is very rarely reported. In this report, we present 4 cases of patients with different symptomatology but all with PVNS of the knee who underwent arthroscopic treatment. At short-term follow-up, all patients had complete recovery of their symptoms with no apparent recurrence.

Strength of different meniscus suturing techniques.

We measured and compared the primary stabilities of five different meniscal suturing techniques. The techniques tested were horizontal mattress, vertical mattress, knot-end, vertical, and vertical loop. Twenty bovine medial menisci were cut to simulate peripheral longitudinal tears and repaired with one of the five suture techniques. Then the two parts of the meniscus were pulled using the Instron Tensometer until failure occurred. Knot-end techniques gave inferior results (mean ultimate failure strength 64 +/- 5 N) compared with the other techniques. Vertical mattress failed at 130 +/- 3 N, vertical loop at 128 +/- 4.5 N, horizontal mattress at 98 +/- 5 N and vertical suturing at 136 +/- 2.7 N. This study shows the superior mechanical characteristic of the vertical suturing technique.
