Long-term clinical outcomes and retrieval analysis of a cementless total knee replacement in a dog.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveThe aim of the study was to describe long-term outcomes and report post-retrieval implant analysis following cementless total knee replacement (TKR) in a dog. ANIMAL: A seven-year-old, male neutered, Labrador retriever.
methodsThe dog presented for evaluation of chronic left pelvic limb lameness. Orthopedic examination identified bilateral cranial drawer and medial buttress. Radiographs revealed severe bilateral osteoarthritis with moderate joint effusion/synovial hypertrophy. Given the end-stage osteoarthritis, TKR was considered more appropriate than tibial plateau leveling osteotomy (TPLO). The dog underwent a left cementless TKR.
resultsImmediate postoperative radiographs showed appropriate implant positioning. Moderate left pelvic limb lameness with full, pain free and stable stifle range of motion (ROM) was documented at 2 weeks. Increased left hindlimb weight-bearing with a peak vertical force of 70% bodyweight (BW) versus 50% BW on the contralateral leg was reported at 6 weeks. Radiographs showed good implant osseointegration. Left stifle ROM was 50°/170°, a 30° increase compared to preoperative values. Additional rechecks at 14 and 30 weeks showed gradual improvement in stifle ROM and weight-bearing. The dog was euthanized 6 years after surgery for reasons unrelated to TKR. Radiographs demonstrated static implant position without signs of osteolysis and gross examination revealed mild polyethylene wear on the caudal aspects of the tibial insert. Histological evaluation of the implant-bone interface showed extensive and robust osseointegration.
conclusionThis case demonstrates that cementless TKR can be associated with excellent clinical function over the course of at least 6 years and suggests that early surgical intervention could be considered.
