ABSTRACT
Background@#One of the symptoms annoying patients after total knee replacement (TKR) is numbness around the operative scar. Some studies have shown that altering the incision in terms of placement or length may decrease the incidence of numbness. It still remains unknown whether numbness affects patient-reported outcomes. @*Methods@#We conducted a randomized study to compare a short-length incision (n = 50) and a lateral exit incision (n = 50) with a standard midline TKR incision (n = 50) in terms of the incidence of numbness and its progress over 1 year of follow-up. Our secondary objective was to look at the involved zone, area of numbness, and secondary symptoms. We also looked at patient-reported outcome in terms of satisfaction in all groups using a visual analog scale and Forgotten Joint Score. @*Results@#At 3 months postoperatively, the incidence of numbness was least in the lateral exit group: 46.2% as compared to midline (62%) and short (58.3%), but the difference was not significant (p = 0.07). At 6 months, the short incision group had a significantly lower incidence (8%) of residual numbness as compared to 30% in the other two groups (p = 0.003). At 1 year, most patients recovered sensation loss and had similar function. @*Conclusions@#Placement or length of an incision did not significantly affect the incidence of numbness; however, the short incision led to early recovery of numbness. At 1 year of follow-up, most patients did not complain of loss of sensation and had similar functional outcome.
ABSTRACT
Background@#With ever-increasing demand for total knee arthroplasty (TKA), most healthcare systems around the world are concerned about its socioeconomic burden. Most centers have universally adopted well-defined clinical care pathways to minimize adverse outcomes, maximize volume, and limit costs. However, there are no prospective comparative trials reporting benefits of these risk mitigation (RM) strategies. @*Methods@#This is a prospective cohort study comparing post-TKA 90-day complications between patients undergoing RM before surgery and those following a standard protocol (SP). In the RM group, we used a 20-point checklist to screen for modifiable risk factors and evaluate the need for optimizing non-modifiable comorbidities. Only when optimization goals were achieved, patients were offered TKA. @*Results@#TKA was performed in 811 patients in the SP group and in 829 in the RM group, 40% of which were simultaneous bilateral TKA. In both groups, hypertension was the most prevalent comorbidity (48%), followed by diabetes (20%). A total of 43 (5.3%) procedure-related complications were seen over the 90-day postoperative period in the SP group, which was significantly greater than 26 (3.1%) seen in the RM group (p = 0.039). The commonest complication was pulmonary thromboembolic, 6 in each group. Blood transfusion rate was higher in the SP group (6%) than in the RM group (< 1%). @*Conclusions@#Screening and RM can reduce 90-day complications in patients undergoing TKA.
ABSTRACT
Background@#Anterior cruciate ligament reconstruction (ACLR) remains the gold standard treatment for anterior cruciate ligament (ACL) injury. However, a good functional outcome even after a successful surgery depends on multiple factors. It has been observed that certain patients with a chronic ACL injury demonstrate knee instability voluntarily. The authors observed that these patients might not perform well even after a successful surgery. This study aims to assess the outcome after ACL and other ligament reconstruction in patients with voluntary knee instability. @*Methods@#From a total of 824 patients who underwent ACLR, 13 patients with a history of voluntary knee instability were selected, and data of these patients (demographic and clinical profile) were obtained. Outcomes of surgery in this group of patients were evaluated by using Lysholm score and Tegner activity level. @*Results@#All patients were young men with a chronic ACL injury and manifested instability. Associated injuries were lateral meniscus tear in 3 patients, medial meniscus tear in 2, and posterolateral corner (PLC) injury in 3. ACLR was done using the semitendinosus-gracilis graft in all patients. Further, anterolateral ligament reconstruction was done in 2 patients and PLC reconstruction, in 3 patients. The mean Lysholm score was 54.76 (range, 48–62) preoperatively and 60.92 (range, 54–78) at a mean follow-up of 14.3 months (range, 11–26 months). The median Tegner activity level was 6 (range, 5–7) before injury and 4 (range, 3–5) at the final follow-up. Twelve of the 13 patients were able to demonstrate instability voluntarily at the time of the final follow-up. @*Conclusions@#In patients with ACL and other ligament injuries who demonstrated voluntary knee instability, the functional outcome even after successful ligament reconstruction was poor.
ABSTRACT
Background@#The indications for total knee arthroplasty (TKA) have been expanded to include younger, demanding patients. Some TKA patients expect a return to high-performance activities to restore optimum quality of life. The concept of the medial pivot (MP) TKA is that more natural knee kinematics can be achieved by altering the bearing design. In the present study, we compared the early outcomes of MP TKA with posterior-stabilized (PS) TKA in terms of patient-reported outcomes, function, and performance. @*Methods@#This randomized study was performed in a high volume joint replacement facility of a tertiary care military hospital. We enrolled 40 patients each in the MP group and PS group and assessed knee flexion, patient-reported outcome (new Knee Society Score [new KSS]), patient performance (Delaware Osteoarthritis Profile Score [DOPS]), and function (Forgotten Joint Score [FJS]) at 2 years after surgery. @*Results@#Compared to PS group patients, MP group patients had similar patient-reported outcomes assessed by new KSS (satisfaction, expectation, and activity scales) and FJS. MP knee patients had better performance in the timed up and go test (p < 0.026) and self-paced walk test (p < 0.002) of DOPS. The gain in knee flexion (9.3° ± 14°) compared to baseline was significantly greater in the PS group (p < 0.013). @*Conclusions@#When assessed by DOPS, getting up from chair and walking speed were significantly better in MP knee patients than in PS knee patients. However, considering the predictable rollback ensured by cam and post, the PS knee produced better knee flexion. Despite these results, patients were equally satisfied with the two designs.
ABSTRACT
BACKGROUND: Hip fractures are a significant cause of morbidity and mortality in the elderly. Fast-track multidisciplinary co-management of these patients, rapid preoperative optimization, early surgery, and expeditious rehabilitation may minimize morbidity and mortality. In this study, we evaluated outcomes of fixation of hip fractures in the elderly patients managed by Geriatric Hip Fracture Program at a military hospital in India. METHODS: A total of 114 patients above 60 years of age with hip fractures were enrolled. They were comanaged by a team of specialists and fast-tracked to surgery. Independent ambulation with support of a walker was achieved before discharge to home. Patients were followed up for 1 year. RESULTS: The average age of the 114 patients was 77 years; 24 patients were octogenarian. Eighty-four percent of injuries were due to a domestic fall. Hypertension (41%) and diabetes (22%) were the most common comorbidities. All patients were optimized before surgery. The average delay from injury to admission was 1.7 days (range, 0 to 14 days) and that from admission to surgery was 1.8 days (range, 0 to 19 days). Hence, the average time from injury to surgery was 3.5 days. The length of stay in hospital was, as per rehabilitative milestones achieved, 2 to 5 days in 40% of the patients and 6 to 15 days in 60% of the patients. At 1 year after surgery, 95 patients were independently ambulant (56 patients with support and 39 patients without support). Twenty-three percent of the patients had postoperative complications and eight patients died (7.7%) at 1-year follow-up; 11 patients were lost to follow-up. CONCLUSIONS: Elderly hip fracture has a high risk of mortality (14%–58%). Thus, expeditious surgery within 24 hours of admission has been advocated in the Western literature to minimize mortality. Mortality rate at 1 year after surgery remains at 10% to 24%. In our study, even with aggressive co-management, the average delay to hip fracture fixation was more than 3 days; however, the 1-year mortality was relatively low (7.7%). This indicates the importance of preoperative optimization and postoperative rehabilitation for independent ambulation and mortality reduction in the elderly population.
