Osteoarthritis is a degenerative type of arthritis that breakdown cartilages and bones and contributed to high disability incidences. Throughout the world, 0.85% of cases is of hip osteoarthritis. Specific therapeutic exercises such as land-based exercises show a significant impact in osteoarthritis management.

Therefore, to check land-based exercise effect upon hip osteoarthritis and compare its impact with high vs low or uncertain compliance with dose recommendations, a study was conducted. This study involves a systematic review of meta-analyses of supervised exercise programmes among hip osteoarthritis patients. Further, the American College of Sports Medicine's (ACSM) recommendations for developing and maintaining cardio-respiratory fitness, muscular strength and flexibility in healthy adults were used to evaluate and decide dose of exercises interventions. Along with the recommendations, compliance ratios were determined as well. In the whole study, overall 12 studies included which comprised 1202 participants. Out of these 12 studies, seven were classified as "high" and five as "uncertain" compliance with the ACSM recommendations. Further, in meta-analyses for the outcomes pain and self-reported physical function, standardised mean differences (SMDs) were calculated. These outcome effects compared among the sub-groups of studies, including interventions with "high" vs "uncertain" compliance with the ACSM recommendations.

Out of 12, ten studies showed an overall low risk of bias. The standardised mean difference (SMD) was used to analyse the effects of exercise on hip OA as compared to no activity. SMD used to investigate both pain and physical function.

The SMD for pain among high compliance group and uncertain compliance group was -0.42 and 0.04 respectively. It reflects that top compliance group was favouring exercise.  Moreover, SMD for physical function among high compliance group and uncertain was -0.41 and -0.23 respectively.

According to these results, it is concluded that land-based supervised exercise interventions with high compliance to the ACSM recommendations showed better improvements in pain significantly and in self-reported physical function non-significantly as compared with the uncertain agreement.
