Kneeling is an activity that is important in certain occupations and recreational activities. Culturally, kneeling plays a large role in Middle Eastern and Asian countries, where activities of daily living require the ability to kneel and achieve deep knee flexion.

<p><strong>Background:</strong> Osteoarthritis (OA) of knee joint is a common problem in our society causing pain, deformity, oedema, malalignment and limitation of activity. Total knee arthroplasty (TKA) is the surgery done for treatment of this problem. The range of movement obtained after TKA is an important factor influencing success of surgery. Posterior femoral condylar offset (PCO) is one of the parameters influencing range of movement after surgery. The dearth of studies in Indian population and contradicting results in already conducted studies has been observed in assessing the effect of PCO on range of knee flexion in patients undergoing TKA. Hence this study is done to explore this correlation.</p><p><strong>Methods:</strong> A prospective analytical study on 36 patients (50 knees) who underwent cruciate retaining TKA at Department of Orthopaedics, Rajagiri Hospital, Aluva. PCO and posterior femoral condylar offset ratio (PCOR) were calculated radiologically before and after TKA. Range of flexion (ROF) and knee society scores (for functional outcome assessment) were recorded preoperatively and postoperatively (at 6 weeks and 3 months).</p><p><strong>Results:</strong> The study found a strong positive correlation between PCO difference and ROF difference (r=0.735). Strong positive correlation was also found between PCOR difference and ROF difference (r=0.777). Both these correlations were statistically significant (p&lt;0.05).</p><p><strong>Conclusions:</strong> The study enlightened us about the point that PCO is an important factor in attaining a good ROF after cruciate retaining TKA.</p>

Inconsistent data has been reported on the effect of the femoral posterior condyle offset (PCO) on the maximal knee flexion after total knee arthroplasty (TKA). This study investigated the relationship between the postoperative changes of the PCO and the changes of maximal knee flexion after a cruciate retaining (CR) TKA. Nine patients with medial osteoarthritis (OA) in one knee were investigated. Before operation, each index knee was magnetic resonance imaging (MRI) scanned for construction of a three-dimensional (3D) knee model. The patient then performed a maximal weight-bearing (WB) flexion and the index knee flexion was measured using a dual fluoroscopy technique. At an average of 8 months after a CR TKA, all patients performed the same WB knee flexion. The postoperative changes of the PCO, the posterior cruciate ligament (PCL) elongation, and the posterior tibial slope (PTS) were determined. The postoperative changes of maximal knee flexion were determined by comparing with the preoperative maximal flexion angles of the knee. The correlations of the postoperative changes of PCO and PTS with the postoperative changes of the maximal flexion angle and PCL elongation of the knee were analyzed. The preoperative PCO (28.5 ± 4.5 mm) was significantly smaller than the postoperative PCO (31.1 ± 5.1 mm) (p < 0.05). The increasing of PCO after surgery is correlated with the decreasing of maximal knee flexion angle (r = 0.74) and the increasing of PCL elongation (r = 0.64) after the TKA. The PTS was not found to change significantly after the TKA and was not significantly correlated to the maximal knee flexion angle and PCL elongation. The postoperative increases of the PCO were shown to cause overstretching of the PCL and poor flexion angle of the knee after the CR TKA. Restoration of PCO could help optimize the maximal flexion of the knee after the TKA with consideration about PCL tension.
