Abstract Background Despite the innovations in total knee arthroplasty (TKA), there is still a subset of patients who do not acquire significant relief or expected satisfaction after primary TKA. However, this subgroup of patients still gains improvements more or less in terms of objective or quantified assessments after the procedure. The purpose of our study is to explore the factors that correlate with patients’ satisfaction and identify minimal clinically important difference (MCID) and minimum important change (MIC) in clinical parameters. Methods We conducted a retrospective study of 161 patients diagnosed with osteoarthritis who underwent unilateral total knee arthroplasty from January 2017 to December 2017. We collected the following parameters: body mass index (BMI), duration of disease, education level, depression state, preoperative flexion contracture angle of knee, HSS scores, 11-point NRS scores, and radiological parameters (preoperative minimal joint space width and varus angle of knee). The satisfaction was graded by self-reported scores in percentage (0–100). Results We revealed that 80.8% of patients were satisfied 3 years overall after primary TKA. HSS score change, NRS-Walking score change, age, and pre-mJSW showed significant difference between satisfied and dissatisfied group. The varus angle change revealed statistical significance according to the levels of satisfaction. Simple linear regression identified the MCID for HSS score to be 5.41 and for the NRS-Walking to be 1.24. The receiver operating characteristics (ROC) curve identified the MIC for HSS score to be 25.5 and for the NRS-Walking score to be 6.5. Conclusions In summary, we identified several factors that correlated with patients’ satisfaction independently after TKA in a long term. In addition, we revealed the minimal clinically important difference (MCID) and minimum important change (MIC) for HSS and NRS score in these patients.

AbstractAlthough there are numerous studies about routine histopathological analysis during arthroplasty surgeries, most of them showed that new diagnoses have rarely been obtained as a result. The aim of this study was to evaluate the efficacy of routine pathological analyses of synovia resected during primary total knee arthroplasty in patients with osteoarthritis and its relevance in the treatment process. Of the 47 included patients who were followed up prospectively, 26 patients had clinical and histopathological concordant diagnoses and 21 patients had discrepant diagnoses. Oxford knee score and visual analogue score were performed for all the patients. Kallgren-Lawrence score was used for radiological analyses. The Mann-Whitney U test was used to examine the differences between the abnormally distributed variables. Mean age was 65.9 ± 4.3 years (range, 50–89 years) and mean follow-up time was 19 ± 7.8 months (range, 6–39 months). Grade IV gonarthrosis was found to be statistically lower in the discrepant group (p = 0.046). The mean preoperative Oxford knee score was 16.8 ± 2.3 (range, 2–23) and the mean postoperative Oxford knee score was 44.6 ± 1.8 (range, 27–48; p = 0.016). Postoperative Oxford knee scores and VAS were significantly increased in both the concordant and discrepant groups (p = 0.026 and p = 0.035, p = 0.019 and p = 0.039, respectively). Resection and histopathologic analyses of the hypertrophied and inflamed synovium encountered during primary arthroplasty procedure should be performed. This examination not only could provide crucial information that may influence the postoperative follow-up guidelines but also could help us to expand our knowledge and awareness of rare diseases that might yield osteoarthritis. The level of evidence for the study is level II.

Background: Osteoarthritis involves degeneration of articular cartilage seen with increasing age. The knee joint, the most common joint that falls prey to attacks of osteoarthritis, has 30% incidence in population above 60 years. Total knee arthroplasty (TKA) is the main surgical option for orthopaedics. Though it corrects the deformity and relieves pain, yet it is not the treatment of choice in younger population. This study aimed to validate the effects of proximal fibular osteotomy (PFO) as a newer technique in managing medial compartment knee osteoarthritis. Methods: The diagnosed patients for medial compartment knee joint osteoarthritis were selected for study from Dr. Ziauddin University hospital of Karachi. Excluded were aged less than 40 years, or with BMI more than 30, and patients with tri-compartmental arthritis. Medial and lateral joint spaces along with Oxford knee score were measured and recorded pre- and post-operatively. Patients underwent PFO after giving written and informed consent. Results: Total number of patients selected was 30 for this study; 21 (70%) females, and 9 (30%) males (mean age 58.8 years). Mean pre-operative measured medial joint space on standard antero-posterior (AP) radiograph was 0.442± 0.04 cm. Mean recorded pre-operative Oxford knee score was 23.87±3.74 mm. Improvement was observed in mean postoperative medial joint space to 0.572± 0 .066 cm and mean post-operative Oxford knee score to 40.2±5.8mm. Conclusion: This study concludes that PFO significantly improves joint function in patients with medial compartment osteoarthritis knee and may delay the need for total knee arthroplasty, if carried out at an appropriate stage.
