Tendon and Ligament Injuries

The medical records of cats receiving surgical treatment for unilateral patellar ligament rupture between 1999 and 2012 at 12 referral centres in the UK and Ireland were reviewed. Seven cases were identified: six were caused by trauma and one was iatrogenic, occurring as a complication following surgical stabilisation of a tibial fracture.

OBJECTIVE: To (1) describe a modified technique for tibial tuberosity advancement (TTA) in dogs with cranial cruciate ligament (CCL) rupture and (2) report short term outcome and complications.

STUDY DESIGN: Prospective clinical study.

ANIMALS: Dogs with unilateral CCL rupture (n = 50).

METHODS: TTA was performed with a novel implant to achieve advancement of the tibial crest. The technical protocol, specific implants and instrumentation, and the short term outcome are described.

OBJECTIVE: To evaluate factors related to meniscal pathology and their effect on clinical outcome in dogs treated for cranial cruciate ligament (CCL) disease.

STUDY DESIGN: Prospective cross-sectional study.

ANIMALS: Dogs (n = 163) with CCL disease (n = 223 stifles).

OBJECTIVE: To describe veterinarians' treatment recommendations and decision-making factors for dogs with cranial cruciate ligament disease (CCLD).

OBJECTIVE: To biomechanically compare different loop and crimp configurations used for extracapsular suture stabilization of the CCL-deficient stifle.

STUDY DESIGN: In vitro study.

SAMPLE POPULATION: Crimped loop constructs of 100 lb Ande type nylon leader line in 7 different configurations comprising single and double loops, single and double crimps, and the interlocking loop configuration.

OBJECTIVE: To assess the influence of locking plate and screw implants on postoperative infection rate in dogs >50 kg undergoing tibial plateau leveling osteotomy (TPLO).
STUDY DESIGN: Retrospective case series.
ANIMALS: Dogs >50 kg (n = 208) that had TPLO.

OBJECTIVE: To (1) investigate the use of K-wires as alignment aids for cranial closing wedgeostectomy (CCWO) and (2) evaluate their effect on osteotomy accuracy and angular/rotational alignment.
STUDY DESIGN: Cadaveric study.
ANIMALS: Cadaveric pelvic limbs (n = 20).

To evaluate the relationship between tibial plateau angle (TPA) and strain in the intact cranial cruciate ligament (CCL) during axial loading.

The purpose of this study was to evaluate short-term complications associated with the tibial plateau leveling osteotomy (TPLO) procedure in dogs of small and medium sizes. These study findings could then be compared with similar studies in dogs of all sizes. Ninety-eight procedures (82 dogs) using 2 or 2.7 mm TPLO plates were included spanning a 6 yr period with a minimum of an 8 wk follow-up period. The overall complication rate was 36%.

The main objectives were to evaluate the impact of femorotibial subluxation on the preoperative measurements for tibial tuberosity advancement (TTA) by defining radiographic landmarks and testing the repeatability for assessing cranial tibial subluxation (CTS). Also, we aimed at developing a formula to calculate the necessary adjustment in measurement of TTA in stifles with CTS.
