Introduction: The hip joint is the most important joint of the body as it enables a person to assume various postures. Diseases of this joint are always alarming because if untreated, produces serious disability, for this reason various methods of management of hip diseases have been devised, but failure of conventional management in advanced stages of hip diseases like AVN, osteoarthritis, rheumatoid arthritis, congenital subluxation or dislocation, bone tumor etc. have brought a new surgical era of Total Hip Replacement. By relieving pain, total hip arthroplasty has probably given more pleasure to humankind than any other surgical procedure. THR is the most common adult reconstructive hip procedure performed in the western countries. By doing our study we want to study various aspects of uncemented THR and to see early and midterm complication of uncemented THR and compare with other studies.

Aim: The aim of this work is to study patients with advanced stages of hip diseases operated by Uncemented THR.

Materials and methods: This was the retrospective study of 23 cases operated with uncemented total hip arthroplasty with at least 2 years follow up at the tertiary care center hospital affiliated with medical college. Cases belonging to various age groups and having various pathologies of hip joint and treated with uncemented THR were assessed in respect to post-operative betterment of short and long term follow up. Patients were included in the study as per the inclusion and exclusion criteria. At regular follow-ups, patients were assessed as per the Harris hip score and X-ray findings. Results and Discussion: The study comprise of post-operative result of Uncemented Total hip replacement. In comparison of other published series, it is a small study. All patients included in my study were operated with modified gibbson postero-lateral approach. All the patients in my studies were having acceptable range of motion scale according to modified Harris hip score.90%patients regained their abductor powers postoperatively indicating importance of post-operative abductor strengthening exercises. These reults were comparable to other published studies.

Conclusion: In our study comparing the following parameters of, functional limp, range of motion, daily activity affection and Harris hip score doesn't show any significant difference among our reference study and functional results of the patients are good suggesting that uncemented total hip replacement prosthesis is good modality to treat the patients with advanced hip arthritis especially young patients.
