“…Non-steroidal anti-inflammatory drugs and analgesia with buprenorphine was administered to try and facilitate limb use and mobilisation, as is widely recommended during management and rehabilitation of muscle contractures in dogs and cats. 12 , 17 In this case, conventional treatments resulted in initial improvement, followed by recurrence of contracture. Initiating treatment with the corticosteroid prednisolone coincided with an almost immediate improvement in clinical state and stopped the apparent rapid tendency for contracture to recur.…”

Case summaryA 6-month-old cat was successfully treated for bilateral quadriceps contracture. Conventional treatments including surgery, dynamic flexion apparatus and physical therapy along with analgesics and non-steroidal anti-inflammatory drugs resulted in temporary clinical improvement that was relapsing. The initiation of supplementary corticosteroid treatment with prednisolone coincided with an immediate and sustained clinical improvement and long-term resolution.Relevance and novel informationSuccessful treatment of bilateral quadriceps contracture has not previously been reported in a cat. Quadriceps contracture remains a challenging condition to treat with some cases unresponsive to therapy. Systemic prednisolone treatment appeared to be of benefit in the management of this case and may have a role in some cats where muscle contracture appears relapsing in nature. Further prospective investigations in cats with muscle contracture, including muscle biopsies of affected cats, are warranted.

“…Lameness due to quadriceps contracture occurs 3 to 5 weeks after injury [ 1 ]. When arthrogenic contracture occurs, the prognosis for treatment to return to normal function is poor [ 4 ].…”

“…Quadriceps contracture is characterized by the replacement of the quadriceps muscle–tendon unit with fibrous tissue, resulting in a shortening of the quadriceps muscle, limiting the range of stifle joint motion, and leading to muscle atrophy and fibrosis [ 1 , 2 ]. The important factor of quadriceps contracture is long-term stifle joint immobilization following orthopedic surgery [ 3 , 4 ]. The prognosis for limb function depends on the degree of quadriceps contracture [ 3 , 4 , 5 ]: the earlier the diagnosis, the better the prognosis [ 2 ].…”

“…Blood biochemistry panels tend to be within the normal range, although creatinine phosphokinase levels may be increased [ 2 ]. Atrophy of the quadriceps muscle can cause it to feel like a thickened cord when palpated [ 1 , 4 ]. As the disease progresses, the elasticity of the quadriceps muscle decreases and muscle stiffness increases.…”

Quadriceps contracture is an abnormal pathological shortening of the muscle–tendon unit. To improve the prognosis of quadriceps contracture, improvement of its diagnostic method is needed. In this study, we evaluated the diagnostic utility of ultrasound shear wave elastography in a rat model of quadriceps contracture induced by immobilization. Fifty Wistar rats were randomly divided into control and immobilization groups. During up to 4 weeks of joint immobilization, the quadriceps elastic modulus, muscle hardness, creatinine phosphokinase levels, joint range of motion, histopathologic parameters, and levels of fibrosis-associated mRNA expression were measured every week in the immobilization and control groups and compared. In the immobilization group, the elastic modulus gradually but significantly increased (p < 0.05) throughout the immobilization period. However, muscle hardness and serum creatinine phosphokinase levels only increased at 1 and 2 weeks after the start of immobilization, respectively. Muscle atrophy and shortening progressed throughout the immobilization group. Collagen type I and III, α-SMA protein, and mRNA expression of IL-1β and TGF-β1 significantly increased (p < 0.05) throughout in the immobilization group. Ultrasound shear wave elastography is the most useful method for clinical assessment of muscle contracture.
