Abstract:
Objective To observe the temporary loss(re-falling)of knee range of motion(ROM)during rehabilitation after arthroly-sis for post-traumatic knee stiffness,and analyze the factors related to it. Methods From July,2016 to September,2019,64 patients(68 knees)in Beijing Bo'ai Hospital accepted minimally inva-sive arthrolysis for post-traumatic knee stiffness,and were followed up for twelve months.ROM of flexion and extension of knee was measured before operation,and one,six and twelve weeks,and six and twelve months af-ter operation;while they were asssessed with Hospital for Special Surgery Knee Score(HSS).Multivariate Logis-tic regression was performed on re-falling. Results The ROM and HSS score improved as a whole after operation;however,HSS score improved constantly,but ROM decreased six weeks after operation compared with that one weeks after operation,involving 46 knees of 44 cases.Arthrolysis longer than 12 months from primary injuries,multiple complicated fracture and history of infection were the risk factors for re-falling(OR＞8.058,P＜0.05). Conclusion Minimally invasive arthrolysis is effective on knee function after arthrolysis for post-traumatic knee stiff-ness.However,re-falling of ROM may happen during rehabilitation.Delay of operation,multiple complicated fracture and history of infection may increase the risk of re-falling.
