Cranial cruciate ligament rupture is the single most common cause of hind limb lameness in dogs, affecting an estimated one to three percent of the canine population. For many dogs, surgery is only the beginning of a long road back to comfortable, confident movement — and what happens in the weeks that follow the procedure can determine how fully they recover. This thesis by Mia Kitter, a qualified osteopath D.O. MNOF with a background in human practice, examines whether osteopathic manual therapy has a meaningful role to play in post-operative CCL rehabilitation. The investigation draws on both canine-specific research and human ACL and knee osteoarthritis studies to build a case for OMT as a valuable adjunct in the recovery process. The paper covers three interlocking areas: the nature of CCL injuries and the physiological changes that follow surgery, the application of osteopathic techniques in the post-operative phase, and the diagnostic challenges that make measuring improvement in dogs genuinely difficult. Each of these threads reveals just how complex recovery really is — from rapid quadriceps atrophy in the early weeks post-surgery, to the compensatory tension that builds in surrounding musculature, to the limitations of pain assessment in a patient who cannot speak. The available evidence, while limited by small sample sizes and a high risk of bias in many studies, consistently points in the same direction: manual therapy combined with home exercise programmes produces meaningfully better outcomes than exercise alone. One RCT in humans with knee osteoarthritis found significantly greater pain relief and functional improvement in the group receiving OMT, a finding Kitter draws careful parallels with for canine patients who frequently develop osteoarthritis following CCL injury. The call for larger, better-designed randomised controlled trials is clear — but so too is the clinical promise that already exists.
