In the literature many studies can be found addressing the effectiveness of individual measures and therapies within the medical rehabilitation. The duration of the rehabilitation itself is rarely taken into account. Consequently the duration of postoperative inpatient medical rehabilitation after initial implantation of alloarthroplastic hip and knee replacements in osteoarthritis of the hip or knee was the object of our analysis.
In the present prospective study 100 patients each with osteoarthritis of the hip or knee were presented at a follow-up treatment postoperatively after primary implantation of alloarthroplastic hip and knee replacements. Two different scores were used (Staffelstein score, Lequesne score), which were collected at a weekly follow-up (T1-T4) to determine the degree of mobility in the initial examination of the patient and after three weeks. By setting a target score at admission of the patient to the CSO, which stood for achieving the rehabilitation objective, the rehabilitation period could be changed individually.
Our study showed that the highest rehabilitation progress has been achieved in both the total hip replacement and total knee replacement in patients at the end of the second week of rehabilitation (T2-T3). Thus, in the Staffelstein score 74 % (n = 74) of hip replacement patients and 46 % (n = 46) of knee replacement patients had already reached their rehabilitation aim between T2 and T3. From the third week on there was a marked flattening of the rehabilitation progress. Also the Lequesne scores obtained confirmed these results.
Based on the score-driven detection of mobility degree of rehabilitation at the beginning of the follow-up treatment, the individual design of the rehabilitation process with the active participation of the patient is possible. In a large number of cases a reduction of the rehabilitation period can be achieved to less than 21 days. This finding is particularly important in times of limited financial resources, because the saved resources can be used for other rehabilitation groups. Therefore, in a greater number of patients, a shortening of the duration of the rehabilitation is possible.
