The Cartilage Oligomeric Matrix Protein (COMP) is a glycoprotein that is elevated in patients with osteoarthritis. The elevation increases linearly with the radiological grade of osteoarthritis. The objective of this study was to study the levels of COMP in knee osteoarthritis in the Indian population and to correlate (establish ranges) with the specific radiological grade of osteoarthritis (Kellgreen and Lawrence grading). Since the radiological classification is subjective, the COMP levels would serve as a more objective way of classifying osteoarthritic joints. We analysed the COMP levels by the Enzyme Linked Immunosorbent Assay (ELISA) method in 100 patients presenting to the outpatient clinic of our hospital, after obtaining due approvals. The radiographs of these patients were classified according to the Kellgreen-Lawrence grading by a senior orthopaedic surgeon.Introduction and Objective
Materials and Methods
Patients undergoing total knee arthroplasty (TKA) with end-stage osteoarthritis of knee have secondary foot and ankle pathology. Some compensatory changes occur at ankle and subtalar joint secondary to malalignment and deformity at the knee joint. Purpose was to evaluate the changes in hindfoot malalignment and foot deformities in patients with advanced osteoarthritis of knee requiring TKA and effect of correction of knee deformities post TKA on foot/Ankle alignment. 61 consecutive patients with Kellgren-Lawrence grade IV osteoarthritis knee undergoing TKA were enrolled in a prospective blinded study. Demographic data, deformities at knee and ankle, hindfoot malalignment and functional outcome scores such as VAS, KSS, WOMAC scores, Foot and Ankle Disability Index (FADI) and Foot posture index (FPI) were recorded preoperatively and postoperatively at 6, 12 weeks and final follow up (range: 6–21 months; mean: 14.2months).Introduction
Methods
Advanced osteoarthritis of knee is associated with low-backache in a significant number of patients and adversely affects the quality of life. There is a paucity of literature describing outcomes of backache after total-knee-arthroplasty (TKA). We evaluated backache in patients of advanced knee-osteoarthritis and their functional and radiological outcomes after TKA after approval from Institutional ethics committee. Fifty-nine patients (40 females and 19 males) were included. Mean body-mass index was 28.7. Mean visual analogue score (VAS) for knee-pain was 7.98 preoperatively and 1.6 in follow-up. For chronic backache, the mean VAS score improved from 6.08 to 2.4, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) improved from 67.5 to 37.8, Knee society score (KSS) from 49.8 to 76.6, Oswestry Disability Index (ODI) Score from 55.44 to 34.65 and SF-36 Quality-of-life score from 44.95 to 74.63. There was a significant correlation between in knee and low-back functional scores. Magnetic resonance imaging-based scoring of degenerative changes (Pfirrmann grading) showed improvement only in 13.5% patients; 56% showed no change and 30.5% showed deterioration of scores. Chronic low backache is a significant co-morbidity in advanced knee-osteoarthritis. TKA has the potential to relieve backache along with knee-pain and improves quality of life.
Collapse of femoral head associated with end-stage arthritis form hallmark of osteonecrosis of femoral head. Purpose was to assess efficacy of platelet rich plasma following core decompression in early stage of osteonecrosis of femoral head. Forty consecutive age, sex and BMI-matched patients of osteonecrosis were enrolled for this prospective randomized comparative double blinded clinical study. 19 patients belonged to intervention group (PRP with Core decompression) and 21 to control (Core decompression) group. 8ml of autologous PRP was injected into channels alongwith Calcium Chloride (4:1) after core decompression. Patients were assessed for outcome measures by pain score, functional and Harris Hip scores, Modified Kerboul angle (combined necrotic angle) in MRI. Patients were followed up after 6, 24 weeks and final follow up (mean 10.33 months).Introduction
Methods
There is no effective therapy available today that alters the pathobiologic course of osteoarthritis. Recent advances have shown Mesenchymal stem cells to be a potential disease modifying treatment. Considering the tissue differentiation property and vast paracrine effects of MSCs we proposed the present study to find out the safety and efficacy of Mesenchymal stem cells in osteoarthritis of knee joint. 12 patients with grade 1and2 bilateral osteoarthritis knee (Ahlbacks radiological grading) were selected. 8–10 ml of bone marrow was aspirated under strict aseptic precautions from the iliac spine. After the stem cell culture and expansion for 4–6 weeks the MSC suspension in 10xPBS was injected directly into the 24 knees by lateral approach. The outcome was evaluated by modified VAS score, WOMAC score, KOOS and MRI measurement of knee articular cartilage integrity by the modified WORMS score.INTRODUCTION
