“…In weiteren tierexperimentellen Untersuchungen wurden die biologischen Reaktionen von Knorpelzellen nach mechanischer oberfl/ichlicher oder subchondraler Abtragung fiber lfingere postoperative Zeiten untersucht: Nach oberfl/ichlichem Shaving in Kaninchenkniegelenken [7] oder in Temporomandibulargelenken von Affen [14] konnte keine vom Knorpel ausgehende Heilung [14], sondern tiefgreifende Degenerationen und Nekrosen beobachtet werden [7]. Subchondrale L/isionen heilten bei Kaninchen [7] durch Bildung hyalinartiger Strukturen unterschiedlicher Qualit/it nach 12 Wochen aus, abweichend yon diesen Ergebnissen wurde im Temporomandibulargelenk yon Affen eine vom Knochenmark ausgehende Reparation durch fibr6ses Bindegewebe beobachtet.…”

“…Unsere Ergebnisse weisen wie auch zahlreiche andere tierexperimentelle Untersuchungen zur mechanischen und Lasertherapie [7,14,23] und auch klinische Untersuchungen [1,18,22] darauf hin, einen fl/ichenhaften Einsatz des Lasers zu vermeiden und nut Osteophyten abzutragen. In unserer Lasergruppe hat sich gezeigt, dab die Abtragung in einem Umfang, der vom Operateur f/Jr erforderlich gehalten wird, einen Monat postoperativ eine wesentlich tiefergreifende Gewebereaktion zur Folge hat, die w/ihrend des Eingriffes nicht absehbar ist.…”

The aim of this work was to investigate and evaluate the tissue reactions after sham operation and after mechanical and holmium laser chondral debridement in a rabbit model at different postoperative intervals. In 27 rabbits an arthrosis was induced by implantation of a piece of polyethylene sheeting in one knee joint. After 5 months, distinct arthritic changes had developed. Nine animals each were randomized for sham operation, mechanical debridement, and holmium laser chondral debridement. At 1 day, 1 month, and 3 months postoperatively, three animals in each group were sacrificed and their joints examined grossly and microscopically. At 3 months after mechanical debridement the articular surface was relatively smooth, and tears and defects were filled with fibrous repair tissue. After holmium laser debridement chondral necroses were regularly found, occasionally with damage to the subchondral bone and distinct inflammation in the marrow space. The articular surface remained rough and uneven. These preliminary results suggest that use of the holmium laser is not superior to mechanical methods for remodelling and smoothing of fairly large chondral areas.

“…Significantly increased BrdU-labelled cells were observed at 4 week post-operatively peak. Marciani et al (1988) observed that the condylar surfaces were repaired mainly by fibrous connective tissue which was produced by cells derived from the underlying marrow spaces. Similar findings have been reported by Hochman & Laskin (1965) in rabbits.…”

“…In our study, the labelled cells were seen in the mesenchymal cells of the superficial cancellous bone, which suggests that the fibrous tissue might originate from these labelled cells in the superficial cancellous bone. Furthermore, Marciani et al (1988) described that the residual condylar cartilage did not play a significant role in this process. Depalma et al (1966) also described that the articular cartilage of the femoral condyles in dogs did not contribute significantly to the repair of surgically induced cartilaginous defect.…”

Total discectomy was performed experimentally in the rabbit temporomandibular joint (TMJ). In order to evaluate the injury and repair of the articular cartilage of the mandibular condyle after discectomy, both histologic and immunohistochemical observations were made. Immunohistochemical observation by using bromodeoxyuridine (BrdU) and its monoclonal antibody in vivo labelling method was used. The present study demonstrated that the cartilage on the articular surface of the condyle disappeared at 1 week post-operatively. This defect in the injured articular cartilage was not repaired by the cartilage, but was covered by a fibrous connective tissue at 6 weeks post-operatively, where the condylar recontouring by the adjacent articular cartilage, and flattening and hyperplasia of the condyle were observed. Thus, the cartilaginous repair following discectomy was characterized by the proliferation of the adjacent cartilage to the injured site and osteoblastic formation in the bone marrow at the exposed subchondral bone.
