OBJECTIVE: To characterize donor and recipient sites for autologous osteochondral transplantation in the canine stifle joint with respect to split-line pattern and cartilage thickness. STUDY DESIGN: In vitro study. Sample Population- Stifle joints (n=30) of dogs >20 kg. METHODS: Collagen network orientation of the hyaline cartilage coverage of the distal femur was assessed using split-line technique (n=10).

Osgood-Schlatter disease (OSD) is a condition affecting human adolescents in which there is partial separation of bone fragments from the tibial tuberosity at the site of insertion of the patellar ligament to the tibial tuberosity. Tensile trauma seems to be the most likely aetiology. Clinical signs in people consist of swelling and pain at the proximal part of the tibial tuberosity and around the distal end of patellar ligament. Radiographs frequently show small ossicles at the patellar ligament insertion. Conservative treatment is usually curative.

Objectives: The objective of this study was to evaluate the effects of fabella-tibial suture (FTS) on long-term outcome in dogs with cranial cruciate ligament (CCL) insufficiency and concurrent medial meniscal tear (MMT) that were managed by an open, caudal pole medial meniscectomy (CPMM). Methods: A retrospective review was performed of the clinical records of dogs treated for CCL insufficiency with concurrent MMT by open CPMM, with or without the non-random addition of a nylon FTS according to surgeon preference, during the period of 2001 to 2004.

OBJECTIVE: To assess the usefulness of computed tomography arthrography of the stifle in diagnosing meniscal tears in dogs with cranial cruciate ligament insufficiency. METHODS: A prospective clinical study was performed. Dogs were included if they had evidence of cranial cruciate ligament insufficiency or persistent or recurrent lameness following surgery for cranial cruciate ligament insufficiency. Dogs were sedated for a computed tomography scan of the affected stifle, orientated in the dorsal plane. A survey computed tomography scan was followed by a computed tomography arthrogram.

Objective—To determine the incidence of, and risk factors for, fibular fracture after tibial plateau leveling osteotomy (TPLO) in dogs.
Study Design—Case series.
Sample Population—TPLO (n=168) on 142 dogs.
Methods—Medical records (January 2006–September 2007) and radiographs of all dogs that had TPLO were reviewed. Data retrieved were breed, sex, age, weight, type of plate, use of a jig, time to recheck, preoperative tibial plateau angle (TPA), immediate postoperative TPA, and presence or absence of fibular fracture.

Objective—To compare rates of contralateral cranial cruciate ligament rupture (CCLR) in Labradors based on age and weight at initial rupture, sex, and tibial plateau angle (TPA) and to determine whether Labradors that rupture their initial cranial cruciate ligament (CCL) at an earlier age (<4 years) are more likely to rupture their contralateral side within a certain period of time.
Study Design—Case series.
Animals—Labradors (n=94) that had tibial plateau leveling osteotomy (TPLO).

Objective—To evaluate after 12 weeks the effects of caudal medial meniscal release (MR) in the cranial cruciate ligament-intact canine stifle.

Abnormal patterns of cell death, including increased apoptosis, can influence homeostasis of ligaments and could be involved in the pathogenesis of cranial cruciate ligament (CCL) rupture. Increased nitric oxide (NO) production has been implicated as a stimulus to increased apoptosis in articular cartilage.
