Clinical Trial Summary

The aim of this research is to assess the effects of the Otago Exercise Program on Rehabilitation outcomes of balance strength and functional outcomes of post Total Knee Replacement patients. A randomized controlled trial that will include a total of 44 participants divided into two groups control and experimental. The experimental group will receive the Otago Exercise Program for four weeks, three times per week for forty to forty-five minutes. The control group will receive general TKR protocol for four weeks, three times per week for 30 minutes. Data collected will be analyzed through SPSS 25.

Description:

Total knee replacement (TKR) is one of the most effective surgical interventions for the relief of pain and functional recovery in patients with advanced osteoarthritis (OA) of the knee. In this procedure, the knee joint is resurfaced with a metal or plastic implant intended to restore function, provide pain relief, and improve quality of life. According to a study in Pakistan, a total of 14,875 people had total knee replacement in the last seven years from 2014 to 2021 with a rate of 14.8/100,000 population. In the United States, estimates of TKR incidence lie at 400,000 each year, a figure expected to grow 143% by 2050 even through conservative projections. TKR is considered one of the most effective procedures in orthopedic surgery, but electing for it is far from straightforward: noninvasive alternatives such as weight loss, physical therapy, and NSAIDs are first exhausted. If unsuccessful, a patient will undergo a thorough examination of clinical history and comprehensive imaging of the joint to determine if a TKR is feasible, and if so, the desired implant design and size. Despite the improvements in surgical techniques, the outcomes after TKR remain strongly influenced by the adequacy of rehabilitation and the consequent functional recovery. Rehabilitation, with a particular emphasis on physiotherapy and exercise, is widely promoted after TKR. During the hospital stay, physiotherapy targets mobilization and achievement of functional goals relating to hospital discharge. Further post-discharge physiotherapy and exercise-based interventions promote strength and balance re-training and functional improvement. However, the provision of these services varies in content and duration. However, it has been reported that patients with TKR do not fully recover balance and proprioception in the long-term, remaining clearly below the "abilities" of their healthy matched controls. Low balance and proprioception have been ascribed to the loss of knee receptors located in the structures such as the menisci, the cruciate ligaments, and the cartilage, which are removed for the prosthesis implant. The Otago Exercise Program (OEP) is a home-based balance and strength training program that reduces falls and promotes muscle strength and balance in daily life.OEP is a multi-modal training method that integrates warm-up exercises (5 movements), progressive muscle strength training (5 movements), balance training (12 movements), walking sessions, and aerobic exercise. Initially, The most significant effects on fall reduction induced by the Otago program were only seen in patients who are 80 years or older but now it has shown promise in diverse rehabilitation contexts. Considering that muscle strength and balance are critical factors of TKR postoperative rehabilitation, it is plausible that postoperative OEP may provide further benefits. This study will explore the effects of postoperative OEP on rehabilitation outcomes of balance, strength, and functional outcomes in TKR patients in regard to reducing postoperative fall occurrence and enhancing knee function. It is hypothesized that this program (OEP) would be effective with these individuals in accelerating rehabilitation and lowering the risks of falling. We constructed a 4-week intervention plan based on pre-, post and after 2nd week follow-up intervention measures of Otago exercise, and explored more effective intervention strategies of functional exercise after total knee replacement.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Berg balance scale	Consists of 14 tasks and total score of 56.score of 0-20 indicates severe fall risk, 20-45 includes moderate risk of fall and 45-60 illustrates thr functional balances state.	4th week
Secondary	timed up and go (TUG) test	The test measures the time it takes for a person to stand up from a chair, walk a short distance (typically 3 meters) turn around, return and sit back down.	4th week
Secondary	short physical performance battery	The test includes three different domains (walking, sit-to-stand and balance) to assess functional mobility. The test is easy to administer and takes approximately 10 mins. The SPPB includes three sub tests.	4th week
