Hypothesis
This study examines the relationship between tibial slope and active and passive range of motion following total knee arthroplasty.
Conclusion
The posterior tibial slope does not significantly affect the functional outcomes of patients after primary total knee replacement in the initial treatment phase.
Supporting Evidence
- Significant improvements in the average Kujala score and knee ROM were observed at postop day 7 and at the three-month follow-up.
- Patients with a larger PTS angle exhibited higher average Kujala scores and knee ROM, but the correlations were not statistically significant.
- The mean Kujala score increased significantly from pre-op to postop with scores of 54.27 and 73.4 respectively.
Takeaway
The angle of the tibia doesn't really change how well people can move their knees after surgery.
Methodology
This was a prospective observational study involving 40 knees of 30 patients who underwent primary total knee arthroplasty, with assessments at pre-op, post-op day 7, and 3 months post-op.
Potential Biases
Inherent biases exist in patient selection, surgical approaches, and postoperative management protocols.
Limitations
The study was conducted at a single center, which may affect the external validity and reproducibility of the results.
Participant Demographics
The study included 30 participants, with 16 females and 14 males, with a mean age of 58.77 years.
