“…These techniques include mechanical and thermal chondroplasty. [5][6][7][8][9][10] The use of thermal energy-whether laser or radio-frequency generated-has been controversial. The primary issue is the viability and denaturation of the remaining articular cartilage after thermal treatment.…”

The purpose of this study was to create a controlled partial thickness cartilage lesion in a sheep model, and to provide a foundation to study the natural history of the progression of this lesion. Twenty-eight sheep divided into four groups (1, 12, 24, and 52 weeks, n ¼ 7/group) were used in this study. In one stifle, a mechanical tool was used to create a 200 mm partial thickness lesion (1.5 Â 1.5 cm 2 ) on the medial femoral condyle via arthroscopy. Joint fluid was drawn presurgery and after euthanasia for analysis of collage II 3/4 C long (C2C). After euthanasia, the condyle was analyzed by gross appearance, confocal laser microscopy (CLM) for cell viability, scanning electronic microscopy (SEM) for surface roughness, Artscan for cartilage stiffness, and histology for cartilage morphology. The gross appearance of the treated area appeared rough, soft, and swollen compared to untreated control over time. CLM demonstrated that the depth of cell death increased to 590 mm at 52 weeks after surgery. SEM demonstrated that the treated area became more irregular over time. Stiffness of the treated area was significantly less than control by 12 weeks after surgery. Histologic analysis demonstrated that the 12, 24, and 52 week groups had significantly poorer histologic scores than the 1 week group. Joint fluid analysis demonstrated that the treatment group at 1 week had significant higher levels of C2C than the pretreatment baseline data. The results of this study demonstrated that partial thickness injury of cartilage continued to propagate and degenerate over time in this sheep model. Options for the prevention or treatment of this lesion may be tested using this model in the future. ß

“…These techniques, using mechanical instruments (shaver systems, punches, files), laser technologies or electromagnetic radiofrequency energy [17], must be regarded as symptomatic therapy only. Chondral debridement is intended to produce mechanically stable joint areas and to reduce the formation of loose bodies and of chondrodendritic synovitis.…”

“…Patellofemoral joints of patients were evaluated according to the scoring system defined by FulkersonShea (14). In this scoring system, conditions such as limp, mobility, aid dependency, stair climbing, squatting, insta-bility, pain and swelling are scored and total result is obtained in order to evaluate the condition of patellofemoral joint.…”
