Plain-English summary
A group of 44 dogs with hip joint pain underwent a total hip replacement (THR) surgery to relieve their discomfort. Before the surgery, the dogs showed no difference in sensitivity between their affected and unaffected legs. However, after 12 months, both legs showed improved sensitivity, indicating that the surgery helped reduce pain and improve limb function. The study found that leaner male dogs experienced even greater improvements in sensitivity. Overall, the surgery was successful in alleviating pain and enhancing the dogs' quality of life.

Abstract
OBJECTIVES: To compare von Frey mechanical quantitative sensory thresholds (mQSTvF ) between pelvic limbs in dogs before unilateral total hip replacement (THR) surgery; to correlate ground reaction forces (GRF) with mQSTvF ; to assess changes in mQSTvF after THR surgery. STUDY DESIGN: Prospective clinical study. ANIMALS: Dogs (n = 44). METHODS: mQSTvF and GRF measured using a pressure sensitive walkway were evaluated before, and 3, 6, and 12 months after, unilateral THR. Measurements were recorded from the affected (operated) pelvic limb (APL) and the non-operated pelvic limb (NPL). Random effects analysis and forwards stepwise linear regression models were used to evaluate the influence of time since surgery and patient factors on mQSTvF thresholds. RESULTS: There were no significant correlations between mQSTvF data and age, bodyweight or the GRF variables. Preoperative mQSTvF measured at the APL and NPL did not differ (P = .909). mQSTvF thresholds increased significantly after 12 months in NPL (P = .047) and APL (P = .001). In addition to time, APL mQSTvF values were significantly affected by sex (higher in males, P = .010) and body condition score (higher in leaner dogs, P = .035) and NPL mQSTvF values by sex (P = .038). CONCLUSION: Successful unilateral THR results in decreased central sensitization after 12 months.
