<p class="abstract"><strong>Background:</strong> Anterior knee pain (AKP) following total knee arthroplasty (TKA) ­­­­­­is one of the complication which cause dissatisfaction in patients. Incidence estimated to be 4-49%. The aim of our study is to know the efficacy of patelloplasty with circumpatellar denervation with diathermy in reducing AKP in primary TKA.</p><p class="abstract"><strong>Methods:</strong> A total of 130 unilateral TKAs’ are divided into 2 groups. Group I (control) includes 65 patients in which only patelloplasty was done. Group II (intervention) includes 65 patients in which both patelloplasty and circumpatellar denervation with diathermy was done and analysed. Mean follow up period was 18 months. Patients were assessed both preoperatively and postoperatively at final follow up.<strong></strong></p><p class="abstract"><strong>Results:</strong> The overall incidence of AKP at follow up (18 months) was 16.9%, with 7.7% in the intervention group and 26.1% in the control group (p&lt;0.05).  Western Ontario and McMaster Universities osteoarthritis index scores were significantly  better in intervention group when compared to control group (28.71±3.948 vs 31.40±3.860). Better results were also found in knee society scores for intervention group compared to control group (166.57±7.941 vs 161.23±11.219); Feller patellar score of  intervention group was significantly better when compared to control group (23.28±2.546 vs 20.69±3.729); the range of knee flexion was similar in both the groups (94.62±12.6 vs 93.54±10.7). In terms of pain referred by the patient at 72 hrs postoperatively, there was statistically significant difference observed according to visual analogue scale.</p><p class="abstract"><strong>Conclusions:</strong> There is statistically significant difference with respect to AKP in patients who have undergone patelloplasty with circumpatellar denervation using diathermy compared with patelloplasty alone.</p><p> </p>

<p class="abstract"><strong>Background:</strong> Total knee arthroplasty (TKA) ­­­­­­is one of the most successful surgical procedure with over 90% survival rate at 10 to 15 years. It provides a stable, pain free range of motion (ROM) for day to day activities. The aim of this study is to evaluate various factors determining ROM after TKA.</p><p class="abstract"><strong>Methods:</strong> 348 patients with 390 knees treated with TKA using cruciate retaining (CR) and posterior stabilized (PS) prosthesis were included and analysed. Mean follow up period was 18 months. Patients were analysed for factors like age, sex, diagnosis, body mass index (BMI), pre-operative exercises, ROM, deformity, posterior femoral condylar offset (PFCO), posterior tibial slope (PTS), post-operative rehabilitation and implant design (CR vs PS). Statistical analysis of above factors on knee ROM was done. Patients were assessed pre-operatively, at 6 weeks, 3, 6, 12 and 18 months post-operatively.<strong></strong></p><p class="abstract"><strong>Results:</strong> Age and sex did not affect the final ROM. The mean knee ROM improved from 86.87° to 96.95°. Factors like BMI, deformity had negative correlation and Pre-operative diagnosis, exercises, knee scores, good preoperative ROM, PFCO, PTS had positive correlation on ROM.</p><p class="abstract"><strong>Conclusions:</strong> Pre-operative exercises, diagnosis, ROM, deformity, BMI, PFCO and PTS were important factors which influence ROM in TKA. Patient selection and preoperative counselling are important for good clinical outcome.</p>

<p class="abstract"><strong>Background:</strong> The aim of this study was to compare the outcomes between open reduction and internal fixation by locking compression plate (LCP) and closed reduction and internal fixation with anterograde interlocking nail (ILN) for the treatment of diaphyseal fractures of the humerus.</p><p class="abstract"><strong>Methods:</strong> This is a prospective comparative study, with diaphyseal fractures of the humerus treated by LCP in 30 patients and with ILN in 30 patients. Patients were followed up to 18 months. The clinical and radiographic outcomes were assessed in terms of union, complications, reoperation rate and functional outcome using the American shoulder and elbow surgeons’ score (ASES) and Stewart and Hundley’s criteria.<strong></strong></p><p class="abstract"><strong>Results:</strong> Union was achieved in 93.3% of patients in LCP group and 90% in ILN group. The mean blood loss in LCP group was 280±22.10 ml (160-400 ml) and in ILN group was 110±17.62 ml (70-150 ml) (p=0.001). The ASES score was 42.47±5.532 in LCP group and 40.93±6.330 in nailing group (p=0.320; p&gt;0.05). Stewart Hundley criteria showed excellent and good results in 26/30 and 17/30 patients in LCP group and ILN group respectively (p=0.070; p&gt;0.05). Complications and re-operation rate were higher in ILN group.</p><p class="abstract"><strong>Conclusions:</strong> Our study concludes that LCP can be considered a better surgical option for the management of diaphyseal fractures of the humerus as it had lower incidence of complications, less re-operation rate and better union rate. However, there is no difference between the two groups in terms of union time and functional outcome.</p>
