Patients Who Have Kellgren-Lawrence Grade 3 and 4 Osteoarthritis Benefit Equally From Total Knee Arthroplasty.

BACKGROUND: Recently, some payers have limited access to total knee arthroplasty (TKA) to patients who have Kellgren-Lawrence (KL) grade 4 osteoarthritis only. This study compared the outcomes of patients who have KL grade 3 and 4 osteoarthritis after TKA to determine if this new policy is justified. METHODS: This was a secondary analysis of a series originally established to collect outcomes for a single, cemented implant design. A total of 152 patients underwent primary, unilateral TKA at two centers from 2014 to 2016. Only patients who had KL grade 3 (n = 69) or 4 (n = 83) osteoarthritis were included. There was no difference in age, sex, American Society of Anesthesiologists score, or preoperative Knee Society Score (KSS) between the groups. Patients who had KL grade 4 disease had a higher body mass index. KSS and Forgotten Joint Score (FJS) were collected preoperatively and at 6 weeks, 6 months, 1 year, and 2 years postoperatively. Generalized linear models were used to compare outcomes. RESULTS: Controlling for demographics, improvements in KSS were comparable between the groups at all time points. There was no difference in KSS, FJS, and the proportion that achieved the patient acceptable symptom state for FJS at 2 years. CONCLUSION: Patients who had KL grade 3 and 4 osteoarthritis experienced similar improvement at all time points up to 2 years after primary TKA. There is no justification for payers to deny access to surgical treatment for patients who have KL grade 3 osteoarthritis and have otherwise failed nonoperative treatment.

Differences in outcomes following total ankle replacement in patients with neutral alignment compared with tibiotalar joint malalignment.

BACKGROUND: Excessive tibiotalar malalignment in the coronal plane has been considered by some to be a contraindication to total ankle replacement. The purpose of the present study was to compare clinical outcomes and physical performance measures according to preoperative tibiotalar alignment. METHODS: One hundred and three patients undergoing total ankle replacement were grouped according to coronal plane tibiotalar alignment. Seventeen patients had an excessive deformity (>15° of varus or valgus), twenty-one had moderate valgus alignment (5° to 15° of valgus), twenty-seven had moderate varus alignment (5° to 15° of varus), and thirty-eight had neutral alignment (<5° of varus or valgus). Outcome measures, including the American Orthopaedic Foot & Ankle Society (AOFAS) hindfoot score, the Foot and Ankle Disability Index (FADI), the Short Form-36 (SF-36), the timed up and go test (TUG), the four square step test (4SST), and walking speed, were assessed preoperatively and at one and two years after total ankle replacement. RESULTS: Coronal plane alignment improved following the procedure, with 36.9% of patients having neutral alignment preoperatively as compared with 95% postoperatively. To achieve this alignment, adjunctive procedures, including deltoid ligament release, lateral ligament reconstruction, and posterior soft-tissue releases, were necessary. Significant improvements were seen for the Page: 3 AOFAS pain, function, alignment, and hindfoot scores (p < 0.001) and the SF-36 subscales of body pain, physical function, and role physical (p < 0.001) following total ankle replacement. Walking speed and the FADI, TUG, and 4SST scores also improved significantly (p < 0.001). Subgroup analysis demonstrated no significant differences in clinical outcomes and physical performance measures based on preoperative coronal plane alignment. CONCLUSIONS: Total ankle replacement improves clinical and functional outcomes independent of preoperative tibiotalar alignment when postoperative alignment is restored to neutral at the time of arthroplasty. LEVEL OF EVIDENCE: Therapeutic level IV. See Instructions for Authors for a complete description of levels of evidence.

Free Vascularized Fibular Grafting for treatment of osteonecrosis of the femoral head secondary to hip dislocation.

Traumatic dislocation of the hip results in osteonecrosis of the femoral head (ONFH) or avascular necrosis (AVN) in approximately 40% of patients. This high-energy event causes an ischemic insult to the femoral head that may lead to ONFH. Here, we investigate use of Free-Vascularized Fibular Grafting (FVFG) in patients with ONFH after traumatic hip dislocation. Thirty-five patients with FVFG for this indication were reviewed (average follow-up 3.3 years, range 1-21). We reviewed patient injury statistics, demographics, preoperative radiographs, pre- and postoperative Harris Hip scores, complications, and rate of conversion to total hip arthroplasty (THA). The majority (81%) of our patients were young males (22 years) with ONFH diagnosed an average of 2 years after injury. The average preoperative Harris Hip score was 64.9 which improved by over 10 points to 76.1 at 1-year follow-up. Seven of 35 patients required conversion to THA at an average of 45 (13-86) months postoperation. After a maximum follow up of 21 years, the remainder of the patients retained their native hips and Harris Hip scores tended to show improved hip function.

Community-based weight management in long-term heart transplant recipients: a pilot study.

BACKGROUND: Heart transplant recipients often suffer from obesity, dyslipidemia, and hypertension thought to be related to triple-drug immunosuppression and poor adherence to diet and exercise. A lifestyle intervention that allows recipients to attend a community-based weight management program may improve health outcomes. OBJECTIVE: To determine (1) the effects of attending a community-based weight management program on weight, systolic and diastolic blood pressure, and the lipid profile; and (2) the feasibility of a community-based program for weight management. METHODS: Twenty-one patients (81% male; age 57 years, 99.7 months since transplantation) participated in a randomized clinical trial and received either weight management counseling (control) or a 6-month scholarship to a structured commercial program (treatment). Using simple analysis of covariance models, group differences were assessed and reported as marginal means. RESULTS: At baseline, there were no demographic differences between groups. There were no differences in outcome variables except weight (control, 102.1 kg vs treatment, 98.3 kg; P= .05). After 6 months, significant differences were found in weight (control, 100.5 kg vs treatment, 95.6 kg; P= .047) and high-density lipoprotein cholesterol (control, 40.6 mg/dL vs treatment, 49.1 mg/dL; P= .044). A marginally significant difference was found in systolic blood pressure (control, 138 mm Hg vs treatment, 121 mm Hg; P= .07). A decrease in diastolic blood pressure (6 mm Hg) was attributed to treatment effect (P = .16). No differences were noted in total cholesterol, triglycerides, or low-density lipoprotein cholesterol. CONCLUSIONS: The structured commercial program appears to be an effective, feasible alternative to usual care. Findings need to be confirmed in future research with a larger sample.
