Introduction Range of motion (ROM) is a major desirable outcome after total knee arthroplasty (TKA). The aim of our study is to analyze the variables determining postoperative knee ROM, following cruciate-substituting TKA of arthritic knees. Methods One-hundred fourteen patients out of a total of 158 patients were studied on the basis of the inclusion criteria. All patients underwent cruciate-substituting TKA in the period between September 2014 and September 2017. Variables such as age, sex, body mass index (BMI), preoperative ROM, mild-to-moderate knee deformity (in both the sagittal and coronal planes) and knee society score (KSS) were recorded for all the patients. The patients were evaluated at intervals and finally at the end of one-year post-surgery. The final ROM and KSS were noted. Data were analyzed in SPSS system using the Kruskal-Wallis test and Mann-Whitney U test. Results Patients with younger age (less than 60 years), more preoperative ROM, and less preoperative fixed flexion deformity (FFD) were found to have better postoperative ROM. The mean preoperative KSS was 42.14 ± 12.02, which improved to 90.86 ± 3.86 postoperatively. Other variables like gender, BMI, and preoperative coronal plane deformity of mild to moderate degree did not have a significant influence on postoperative ROM. Conclusion Postoperative expectations of ROM is an important factor for a successful outcome and is also related to patient satisfaction. Variables like younger age group (less than 60 years), better preoperative ROM and lower preoperative FFD are found to have a better postoperative ROM in patients undergoing cruciate-substituting TKA surgery.

Ipsilateral fracture of the shaft of femur and dislocation of the hip are very rare injuries. There always exists a dilemma regarding the treatment to reduce hip and choosing the appropriate method of fixation for a femur fracture, and a clear consensus is yet to be reached. A number of treatment methods such as the open reduction of femur and fixation followed by hip reduction have been tried so far. Ipsilateral fractures and dislocation occur due to high-energy trauma, and reduction of hip dislocation is considered as an orthopedic emergency. Here, we report a case in which we tried a novel approach by temporarily fixing the femur with an external fixator and reducing the hip dislocation. In the next sitting, we performed femur fixation in a closed manner with an interlocking intramedullary nail. We recommend that this novel method of treatment can be used for such types of injuries.

Cystic lesion around knee usually presents as painless swelling and diagnosed incidentally by imaging for any internal derangement of the knee. Few cases presented with pain. Intra-tendinous patellar ganglion is very rare in location for the disease. Ganglionic cyst usually treated by aspiration followed by steroid and surgical excision in some cases. We reported a case with anterior knee pain due to patellar intra-tendinous ganglion cyst which treated conservatively with no recurrence even after one year.

Total hip arthroplasty (THA) is the treatment of choice for Grade IV avascular necrosis of the femoral head. Dislocation following THA, although rare, is a known complication. Common causes of unsuccessful reduction include interposition of soft tissue, component loosening, malalignment, and inadequate muscle relaxation following anaesthesia. Here, we encountered a rare complication during a single-stage bilateral THA that resulted in a non-concentric reduction on the left side. The pathology was a loose bone piece, which possibly was an osteophyte that was broken.
