A longer recovery period may reduce the risk of re-injury. As per study population statistics, the prevalence of medial meniscus tears (29.64%) in this study were congruent to the rates found in studies by Srivastava etal. The demographic distribution of study population with respect to the mean age, gender distribution and the side affected was similar to the recent studies done on the MD-ACL as a standalone entity [2, 3, 5, 8]. . Notchplasty is an ancillary surgical procedure that consists of reshaping and widening of the intercondylar femoral notch, historically developed and performed with the aim to avoid ACL graft impingement and improve visualization of the lateral wall of the femoral notch during ACLR surgery. Reeducation. All the demographic and biostatistical data was compiled and computed on the SPSS-24 software. Debulking of mucoid ACL in patients undergoing unicompartmental knee arthroplasty significantly reduces the rest pain and improves the final range of motion of the knee joint, subsequently improving the overall functional and clinical outcome of the patient and resulting in greater patient satisfaction.

Sigmund Freud emphasized the importance of the unconscious mind, and a primary assumption of Freudian theory is that the unconscious mind governs behavior to a greater degree than people suspect.Indeed, the goal of psychoanalysis is to make the unconscious conscious. Background. . . Hence, the improvement in ROM, attenuation of rest pain and better long term functional outcome measures supported the hypothesis regarding the positive effect of debulking a MD-ACL in patients undergoing UKA. Inclusion criteria was as follows: (1) clinicoradiological confirmation of MD-ACL and medial compartment osteoarthritis (MCOA) of the affected knee joint; (2) patients with less than 10 of varus or 5 of valgus deformity and (3) patients with no flexion contracture.

In these patients, when UKA is coupled with debulking of the MD-ACL with a predetermined end point, a significant improvement in the overall ROM, rest pain, functional outcome scores and subjective satisfaction of the patient can be achieved. Introduction: Mucoid degeneration of the anterior cruciate ligament (ACL) is commonly treated with arthroscopic debridement of the ACL. The position of the femoral tunnel is important in graft isometry, permitting constant tension of the graft throughout the range of motion of the knee. Accessed Nov. 13, 2018. Pristine condition of the lateral compartment and not more than grade II in the patellofemoral compartment (Ahlbck classification) was confirmed in all cases. [20], Chudasama etal. With an increasing trend of UKA being performed worldwide, the role of addressing concomitant MD-ACL is vital in improving the overall outcome of the patient without causing any instability or implant failure, as shown in this study.
