Abstract Background Total knee arthroplasty (TKA) is the major surgical treatment for end-stage osteoarthritis (OA). Despite its effectiveness, there are about 20% of patients who are dissatisfied with the outcome. Predicting the surgical outcome preoperatively could be beneficial in order to guide clinical decisions. Methods One-hundred and ten knees of 110 consecutive patients who underwent TKAs for varus knees resulting from OA were included in this study. Preoperative varus deformities were evaluated by femorotibial angle (FTA), medial proximal tibial angle (MPTA) and lateral distal femoral angle (LDFA), and classified as a severe varus (SV) or a mild varus (MV) group. The osteophyte score (OS), which we developed originally, was also calculated based on the size of the osteophytes and classified as groups with more or less osteophytes. We compared preoperative and 1-year postoperative range of motion, the Knee Society Score, and Japanese Knee injury Osteoarthritis Outcome Score (KOOS) between SV and MV groups (varus defined by FTA, MPTA, or LDFA), in each group with more or less osteophytes. Results When varus deformities were defined by FTA, regardless of OS, postoperative KOOS subscales and/or the improvement rates were significantly higher in the SV group than in the MV group. When varus defined by MPTA, regardless of OS, there were no significant differences in postoperative KOOS subscales between groups. However, when varus defined by LDFA, scores for pain, activities of daily living (ADL), and quality of life (QOL) on postoperative KOOS and/or the improvement rates were significantly higher in the SV group than in the MV group only in patients with less osteophytes. No significant differences were found between groups in patients with more osteophytes. Conclusions We classified OA types by radiographic measurements of femur and tibia in combination with OS. Postoperative patient-reported outcomes were better in patients with SV knees but were poor in patients with knees with MV deformity and less osteophytes.

Background and Hypothesis: Chiari malformation type I (CM-I) is a common pediatric disorder in which the cerebellar tonsils herniate the foramen magnum with associated spinal symptoms. The purpose of this study is to determine if the preoperative Pediatric Quality of Life Inventory (PedsQL) score is predictive of intermediate-term PedsQL outcomes following Chiari decompression surgery. The utility of preoperative patient-reported outcomes (PROs) to postoperative PROs has been previously demonstrated in adult spine surgery. However, to our knowledge, there is currently no widely accepted tool to predict short-, intermediate-, or long-term outcomes after pediatric Chiari decompression surgery. Project Methods: A prospectively maintained database was retrospectively reviewed. Patients who underwent first-time decompression for symptomatic Chiari malformation were identified and grouped by their preoperative PedsQL scores: mild disability (score 80–100), moderate disability (score 60–80); and severe disability (score < 60). PedsQL outcomes were collected at 6-week, 3-month, and 6-month follow-up. Preoperative PedsQL subgroups were tested for an association with demographic, perioperative characteristics, and improvements between groups by one-way ANOVA, chi-square, or Wilcoxon signed rank test, where appropriate. Results: The postoperative patient- and parent-reported PedsQL values were significantly different between all three groups at 6-weeks, 3-months, and 6-months after surgery (p < 0.05), except at the 6-month timepoint for parent-reported outcomes (p = 0.111). Patients with higher preoperative disability demonstrated statistically significant greater improvements (compared to preoperative score) in parent-reported PedsQL at all timepoints after surgery, except at the 6-month parent-reported outcomes (p = 0.133). Conclusion: Patients with worse preoperative disability, as assessed by PedsQL, experienced lower absolute PedsQL scores at all timepoints after surgery but had greater improvement in short- and intermediate-term PROs. We conclude that PedsQL is an efficient and accurate tool that can quickly assess patient disability in the preoperative period and predict both short-term and long-term surgical outcomes.

Abstract Bakground This meta-analysis was designed to compare postoperative patient-reported outcomes and reoperation rates following unicompartmental knee arthroplasty (UKA) between patients with full-thickness cartilage loss (FTCL) and partial-thickness cartilage loss (PTCL).Methods Multiple databases, including PubMed, Embase, Cochrane Library, and CNKI, were searched to identify studies comparing the Oxford Knee Score (OKS), American Knee Society (AKS) score, and reoperation rates between patients with FTCL and PTCL following UKA. Mean differences were calculated for continuous outcomes, and odds ratios were calculated for binary outcomes.Results A total of 613 UKAs (233 PTCL and 380 FTCL) from five retrospective cohort studies were included. Three studies compared OKSs after ≥2 years of follow-up. The mean difference in postoperative OKSs was significantly higher by 2.92 in the FTCL patients than in the PTCL patients (95% confidence interval [CI] −5.29 to −0.55; P = 0.02). The improvement in the OKS was significantly higher by 2.69 in the FTCL patients than in the PTCL patients (95 % CI −4.79 to −0.60; P = 0.01). AKS-knee and AKS-function scores were assessed in two studies at a mean follow-up time of >3.9 years. The mean difference in AKS-knee scores was similar between the groups (95%CI −9.14 to −3.34; P = 0.36), whereas the pooled mean difference in AKS-function scores was 5.63 higher in the FTCL group (95%CI −9.27 to −1.98; P = 0.002). All studies presented data on reoperation rates and showed that they were statistically higher in patients who underwent UKA with PTCL (OR 2.24, 95%CI 1.15–4.38, P = 0.02).Conclusions Compared with PTCL, FTCL achieved superior postoperative patient-reported outcomes and lower reoperation rates following UKA.

Background: Hip arthroscopy for femoroacetabular impingement syndrome (FAIS) is a rapidly growing field in sports surgery; however, factors associated with poor outcomes and identification of predictor models of inferior clinical outcomes is unclear. Purpose: To analyze predictors of clinical failure and inferior clinical outcomes among patients undergoing hip arthroscopy for treatment of FAIS. Study Design: Case-control study; Level of evidence, 3. Methods: Data were collected and analyzed from consecutive patients who underwent primary hip arthroscopy with routine capsular closure for the treatment of FAIS from a single fellowship-trained surgeon between January 2012 and November 2015. Baseline data, postoperative patient-reported outcomes, and rates of clinical failure and inferior clinical outcomes were recorded at 2 years postoperatively. Clinical failure was defined by revision hip arthroscopy or conversion to total hip arthroplasty. Inferior clinical outcome was defined as not reaching the minimal clinically important difference (MCID) or patient acceptable symptomatic state for Hip Outcome Score–Activities of Daily Living. A multivariate logistic regression analysis was used to identify significant predictors of clinical failure and inferior clinical outcome. Results: Out of 1161 eligible patients, 935 (80.5%) completed 2-year postoperative patient-reported outcomes. The mean ± SD age and body mass index were 33.3 ± 12.3 years and 25.4 ± 8.2 kg/m2, respectively. The overall clinical failure rate was 3.6% (n = 34), including 23 cases (2.5%) of revision hip arthroscopy and 11 cases (1.2%) of conversion to total hip arthroplasty. Predictors of clinical failure were lower preoperative International Hip Outcome Tool score ( P = .016), chronic preoperative pain ( P = .001), and chondromalacia in the affected hip ( P = .04). The inferior clinical outcome group, consisting of those who failed to reach the MCID for Hip Outcome Score–Activities of Daily Living, included 256 patients (27.4%). Predictors of inferior clinical outcomes were Tönnis grade >1 ( P = .01), workers’ compensation ( P < .001), and increased body mass index ( P = .02). Conclusion: This study demonstrates that 73% of all patients treated for symptomatic FAIS with primary hip arthroscopy and routine capsular closure achieved the MCID. Clinical failure is predicted by a number of modifiable and nonmodifiable factors, including chronic preoperative pain and presence of chondromalacia. The current study updates the midterm failure rates and outcomes achievable with hip arthroscopy for FAIS.
