Comparison of the Effect of Dog, Surgeon and Surgical Procedure Variables on Improvement in Eight-Week Static Weight-Bearing following Tibial Plateau Levelling Osteotomy

Abstract

Objective The purpose of this article was to compare the effect of surgeon and tibial plateau levelling osteotomy (TPLO) procedure variations on the outcome of TPLO in naturally occurring cranial cruciate ligament disease. Materials and Methods Records from 142 dogs that had a TPLO procedure were reviewed for information regarding surgical procedure, status of meniscus at the time of surgery, surgeon identity, ACVS diplomate or resident, meniscal release, progression of healing at the progress evaluation based on radiographic interpretation and complications encountered. The primary outcome measure was static force on the affected limb at re-evaluation (42–84 days postoperatively) on a PetSafe Stance Analyzer. Results Re-evaluation tibial plateau angle (TPA) was negatively and significantly correlated with improvement (r = −0.2132, p = 0.013). Postoperative and re-evaluation TPA were all significantly correlated with one another. The amount of TPA change from initial to immediate postoperative values was significantly correlated with the preoperative TPA (r = 0.628, p < 0.001). Surgeon, surgical experience, arthrotomy, meniscal damage, meniscal intervention, complications, postoperative TPA and preoperative TPA had no significant effect on weight-bearing at recheck. Clinical Significance TPLO show improvement of 4.58% body weight on the affected limb at 6 to 12 weeks rechecks on a Stance Analyzer. Surgeon, surgical experience, arthrotomy, meniscal damage, meniscal intervention, complications, postoperative TPA and initial TPA have no effect on this measurement of surgical outcome.

Fortetropin inhibits disuse muscle atrophy in dogs after tibial plateau leveling osteotomy

“…Both groups had increases in percent weight bearing during the period of forced activity restriction, with the difference between the two groups nearing significance (P = 0.10). Percent weight bearing with use of stance analysis has been evaluated for dogs undergoing TPLO [16,17]. A recent publication reported no effect on weight bearing when evaluating surgeon, surgical experience, arthrotomy, meniscal damage, meniscal intervention, complications, postoperative TPA, and initial TPA in dogs undergoing TPLO [16].…”

A recent publication reported no effect on weight bearing when evaluating surgeon, surgical experience, arthrotomy, meniscal damage, meniscal intervention, complications, postoperative TPA, and initial TPA in dogs undergoing TPLO [16]. Our study showed similar increases in percent of weight supported in the affected hind limb in dogs treated with Fortetropin1 than the placebo in the period of forced exercise restriction (week 0 to week 8), with the Fortetropin1 group nearly reaching significance over the placebo group (P = 0.10).…”

Radiographic findings have an association with weight bearing and locomotion in English bulldogs

“…In orthopaedic research, it is currently common to evaluate dynamic musculoskeletal function of the dogs using kinetic or kinematic gait analysis [19][20][21]. Moreover, measurement of static weight bearing [22,23] as well as measurement of range of motion in joints [24,25] are often performed. Although several studies have reported various radiographic abnormalities in English bulldogs [1,9,10,[14][15][16], research evaluating the musculoskeletal function of the dogs and specifically the association of orthopaedic findings with dogs' weight bearing and locomotion is scarce.…”

Evaluation of a modified radiographic union scale for tibial fractures scoring system in staged bilateral tibial plateau leveling osteotomy procedures and comparison of first and second side radiographic bone healing

“…The data suggests that postoperative complications impact TPLO mRUST scores and potentially bone healing. A previous study looked at static force on a limb following TPLOs and showed that complications had no effect on weight‐bearing at recheck 28 . Additional mechanisms beyond Wolff's law may therefore be at play, but prospective studies of TPLO mRUST scoring coupled with force plate analysis would be necessary to evaluate this further.…”

Second, TPLO mRUST scores and therefore bone healing was greater at recheck postoperative radiographs in cases with higher lameness scores at presentation (P = .049).…”
