This is the clinical evidence summary written for health professionals. It is technical, and it lists the research this page was built from. You do not need to read it to understand your treatment or to make a decision about it.

Overview

• Peptide supplements should not currently be recommended as a replacement or adjunct for existing orthopaedic standard of care due to the lack of robust efficacy and safety data [1].
• Specific nutritional supplementation alone might benefit geriatric patients, especially those who are unable to exercise [2].
• Intravenous perioperative protein or amino acid supplementation offers benefits for total joint arthroplasty, while effects on muscle strength and function are mixed [3].
• Glucosamine and chondroitin sulfate have an excellent safety profile and may serve a role as an initial treatment modality for many osteoarthritis patients [4].
• Adjuvant oral supplementation containing collagen, hyaluronic acid, chondroitin sulfate, and plasma proteins may increase the efficacy of physical therapy by shortening the time needed to return to pre-injury activity and reducing analgesic consumption after anterior cruciate ligament reconstruction [5].
• Supplementation of n-3 polyunsaturated fatty acids is effective to relieve pain and improve joint function in patients with osteoarthritis [6].
• The combination of non-steroidal anti-inflammatory drugs and glucosamine sulfate supports efficacy in reducing pain, improving function, and possibly regulating joint damage in knee osteoarthritis [7].
• Supplementation with omega-3 polyunsaturated fatty acids for 3-4 months reduces patient-reported joint pain intensity, minutes of morning stiffness, number of painful and/or tender joints, and NSAID consumption [8].
• Conditionally essential amino acid supplementation has a protective effect against common complications and early skeletal muscle wasting after operative fixation of extremity and pelvic fractures [9].
• Glucosamine sulfate has the potential to relieve pain and improve function with low side effects, but unanswered questions regarding long-term effects and dosage preclude a definitive endorsement [10].
• Nutrition consultation and perioperative supplementation with amino acids and micronutrients are readily available interventions that orthopaedic surgeons can select for malnourished patients [11].
• The appropriate use of some dietary supplements can benefit the athlete, while others may harm the athlete’s health, performance, and/or livelihood and reputation if an antidoping rule violation results [12].
• Nutritional supplementation has been shown to markedly reduce hospital costs by reducing rates of ICU admissions, hospital-associated complications, and hospital-acquired infections [13].
• Glucosamine and chondroitin sulfate may be considered reasonable treatment options as part of a multimodal approach for symptomatic primary hand osteoarthritis if the cost is not prohibitive [14].
• Recommendations for data capture relating to female athlete population characteristics, injuries, illnesses, and other health consequences will improve the quality of epidemiological studies to inform better injury and illness prevention strategies [15].
• The use of low-cost commercially available amino acid supplements resulted in fewer overall complications postoperatively and was a low-risk intervention for the patient population [19].
• Substantial barriers such as inconsistent protocols and patient nonadherence remain in nutritional optimization for spine surgery, highlighting the need for multifactorial assessment and standardization of multidisciplinary nutritional protocols [22].
• Perioperative nutritional optimization has been associated with improved outcomes for patients undergoing spine surgery, but additional investigation is needed to determine effective perioperative nutritional protocols [23].

How It Works

Mechanisms of Action

• Glucosamine may exert analgesic properties through the stimulation of hyaluronic acid production in human osteoarthritic synovium [32].
• Omega-3 fatty acids protect cartilage from acute injury by reducing the mechanical sensitivity of chondrocytes [16].

Perioperative and Postoperative Recovery

• Perioperative essential amino acid supplementation prevents rectus femoris muscle atrophy and accelerates early functional recovery after total knee arthroplasty [30].
• Protein supplementation appears to have beneficial effects on mitigating muscle atrophy in the postoperative period following ACL reconstruction, total hip arthroplasty, total knee arthroplasty, and surgical treatment of hip fracture [24].
• Protein supplementation is a low-cost intervention that is easy to incorporate into perioperative management, and its beneficial effects on muscle strength could potentially reduce the risk of longer-term complications such as falls and periprosthetic fracture [20].
• Oral nutritional supplementation and dietetic assistance represent low-risk interventions that may improve morbidity and mortality in older people after hip fracture [17].

Osteoarthritis and Joint Pain

• Collagen peptides provide significant pain relief in patients with knee osteoarthritis compared to placebo [27].
• An eight-week collagen-based supplement has a positive effect on pain, quality of life levels, and some functional test results in patients with meniscopathy [25].
• Subacromial injection of hydrolyzed collagen is effective in reducing pain and supporting functional recovery in patients with rotator cuff tendinopathy, with effects observed after the first injection and persisting up to six months [29].
• Glucosamine sulfate has the potential to relieve pain and improve function with low side effects, though unanswered questions regarding long-term effects and dosage preclude a definitive endorsement [10].
• The evidence supports the efficacy of glucosamine sulfate in reducing pain, improving function, and possibly regulating joint damage in knee osteoarthritis [7].

Muscle Mass and Strength

• Protein intakes at amounts greater than ~1.6 g/kg/day do not further contribute to resistance training-induced gains in fat-free mass [18].

Limitations and Safety

• Patients do not benefit from creatine supplementation during the first 12 weeks of rehabilitation after anterior cruciate ligament reconstruction [26].
• The appropriate use of some supplements can benefit the athlete, but others may harm the athlete’s health, performance, and/or livelihood and reputation if an antidoping rule violation results [12].

What the Evidence Shows

Perioperative and Postoperative Supplementation

• Intravenous protein or amino acid supplementation offers benefits for total joint arthroplasty, while effects on muscle strength and function are mixed [3].
• Integrating targeted nutrition into prehabilitation pathways may help reduce complications and support faster functional gains in total joint arthroplasty [21].
• Protein supplementation appears to have beneficial effects on mitigating muscle atrophy in the postoperative period following ACLR, THA, TKA, and surgical treatment of hip fracture [24].
• A comprehensive balanced nutrition supplement resulted in lower complication rates and mortality at 120 days postoperatively for hip fracture patients [31].
• The use of a low-cost commercially available amino acid supplement resulted in fewer overall complications postoperatively and was a low-risk intervention for the patient population [19].
• Protein supplementation is a low-cost intervention that is easy to incorporate into perioperative management, and the beneficial effects on muscle strength could potentially reduce the risk of longer-term complications, such as falls and periprosthetic fracture [20].
• Nutrition consultation and perioperative supplementation with amino acids and micronutrients are 2 readily available interventions that orthopaedic surgeons can select for malnourished patients [11].
• Adjuvant oral supplementation may increase the efficacy of physical therapy by shortening the time needed to return to pre-injury activity and the analgesic consumption after anterior cruciate ligament reconstruction [5].
• Specific nutritional supplementation alone might benefit geriatric patients, especially relevant for those who are unable to exercise [2].

Osteoarthritis and Joint Health

• The excellent safety profile of glucosamine and chondroitin sulfate should be discussed with patients, and they may serve a role as an initial treatment modality for many OA patients [4].
• Supplementation of n-3 PUFAs is effective to relieve pain and improve joint function in patients with osteoarthritis [6].
• The evidence supports efficacy of non-steroidal anti-inflammatory drugs and glucosamine sulfate in reducing pain, improving function, and possibly regulating joint damage in knee osteoarthritis [7].
• Supplementation with omega-3 PUFAs for 3-4 months reduces patient reported joint pain intensity, minutes of morning stiffness, number of painful and/or tender joints, and NSAID consumption [8].
• Glucosamine sulfate has potential to relieve pain and improve function with low side effects, but unanswered questions regarding long-term effects and dosage preclude a definitive endorsement [10].
• If the cost is not prohibitive, glucosamine and chondroitin sulfate products may be considered reasonable treatment options as part of a multimodal approach for symptomatic primary hand osteoarthritis [14].
• Oral chondroitin is more effective than placebo on relieving pain and improving physical function, while glucosamine showed effect on stiffness outcome in osteoarthritis [33].
• Collagen peptides demonstrate significant pain relief in patients with knee osteoarthritis compared to those who received placebo [27].
• An eight-week collagen-based supplement had a positive effect on pain and quality of life levels and some functional test results in patients with meniscopathy [25].

Cartilage and Tendon Injuries

• EPA supplementation could offer a promising strategy for preventing PTOA progression following acute cartilage injuries [16].
• Treatment with hydrolyzed collagen was effective in reducing pain and supporting functional recovery in patients with rotator cuff tendinopathy, with effects observed after the first injection and persisting up to six months [29].

Sports Medicine and General Considerations

• With protein supplementation, protein intakes at amounts greater than ~1.6 g/kg/day do not further contribute resistance training-induced gains in fat-free mass [18].
• Patients do not benefit from creatine supplementation during the first 12 weeks of rehabilitation after ACL reconstruction [26].
• Substantial barriers like inconsistent protocols and patient nonadherence remain for nutritional optimization in spine surgery, highlighting the need for multifactorial assessment and standardization of multidisciplinary nutritional protocols [22].

Practical Considerations

Perioperative and Postoperative Supplementation

• Conditionally essential amino acid (CEAA) supplementation has a protective effect against common complications and early skeletal muscle wasting after operative fixation of extremity and pelvic fractures [9].

• Substantial barriers to nutritional optimization in spine surgery include inconsistent protocols and patient nonadherence, highlighting the need for multifactorial assessment and standardization of multidisciplinary nutritional protocols [22].

Osteoarthritis and Joint Health

• The excellent safety profile of glucosamine and chondroitin sulfate should be discussed with patients, and they may serve a role as an initial treatment modality for many osteoarthritis patients [4].
• The lack of substantial evidence currently prevents a ringing endorsement of glucosamine and chondroitin sulfate for osteoarthritis management [10].
• Evidence supports the efficacy of glucosamine sulfate in reducing pain, improving function, and possibly regulating joint damage in knee osteoarthritis [7].
• If the cost is not prohibitive, glucosamine and chondroitin sulfate may be considered reasonable treatment options as part of a multimodal approach for symptomatic primary hand osteoarthritis [14].
• Supplementation of n-3 polyunsaturated fatty acids (PUFAs) is effective to relieve pain and improve joint function in patients with osteoarthritis [6].
• EPA supplementation could offer a promising strategy for preventing post-traumatic osteoarthritis (PTOA) progression following acute cartilage injuries [16].

Musculoskeletal Recovery and Sarcopenia

• Specific nutritional supplementation alone might benefit geriatric patients, especially those who are unable to exercise, as shown by proof-of-principle in a vitamin D and leucine-enriched whey protein study [2].
• With protein supplementation, protein intakes at amounts greater than ~1.6 g/kg/day do not further contribute to resistance training-induced gains in fat-free mass in healthy adults [18].
