GLENO-HUMERAL ARTHRITIS FOLLOWING LATARJET PROCEDURE: RISK-FACTORS, PROGRESSION AND ITS IMPACT ON CLINICAL IMPROVEMENT

Abstract

Objectives: The study aims to evaluate prevalence of postoperative arthritis, its risk factors and impact on clinical recovery following Latarjet procedure.

Methods

A retrospective analysis of 41 cases was conducted with mean follow-up period of 10.95 4.18 (years). Arthritis was staged pre- and postoperatively by Samilson and Prieto classification. Clinical outcome was studied in terms of improvement in pain (Visual Analogue Scale), Rowe score, UCLA shoulder score and range of motion and the results were stratified in terms of arthritis progression.

Results

Pain (VAS), Rowe and UCLA score; all showed significant improvement (p<0.001) from preoperative means of 2.9, 33.41 and 20.82 to 1.36, 85.97 and 31.09 respectively. Nine patients had arthritic shoulders before the surgery while 5 non-arthritic shoulders developed arthritis after the procedure. The arthritic shoulders showed significantly lower (p<0.001) improvement in pain, Rowe and UCLA score (2.428, 79.64 and 28.28) in comparison to improvement noted (i-e 0.814, 89.25 and 32.55 respectively) in non-arthritic shoulders. Postoperative clinical scores were significantly associated with the grade of arthritis; where age at time of surgery (p<0.001), number of preop dislocations (p=0.009) and lateral-overhang of graft (p=0.002) were associated with progression of arthritis. Findings are suggest that despite excellent clinical outcome in terms of stability, Latarjet procedure increases probability of development of arthritis postoperatively. Conclusions: Long-term follow-up of Latarjet procedure is associated with development of arthritis and this adversely affects outcome: where, age at time of surgery, number of preoperative dislocations and lateral-overhang of the graft are associated with postoperative arthritis.
