Treatment
Acute Phase
Rehabilitation Program
Physical Therapy
The initial treatment of all sprains is similar and follows the RICE protocol with rest, ice, compression, and elevation. Protective weightbearing is instituted with crutches. This is continued until a normal gait is obtained. The severity of the injury dictates further treatment.
Grade 1 and 2 sprains are routinely treated nonoperatively. They may be braced with a knee sleeve or a double-upright hinged knee orthosis, individualized to the patient's discomfort. Crutches are only necessary for a few days. These injuries represent incomplete tears and allow for a rapid return to activities.
Historically, grade 3 tears were treated operatively but currently are routinely treated nonoperatively. In the past, nonoperative treatment meant a long leg cast. Currently, bracing with a hinged knee orthosis is common. Some authors recommend immediate braced increase in range of motion (ROM), while others prefer waiting up to 6 weeks with the knee at 30° of flexion. Crutches are usually necessary for 1-2 weeks.
The goals of therapy are to decrease pain, restore ROM, and regain strength. Crutches are used until weightbearing is comfortable. ROM exercises are performed in a cold whirlpool. Quadriceps strengthening is started with quad sets and progressed to closed-chain exercises as tolerated. Running is allowed when weightbearing is comfortable and is progressed to more narrow S-shaped patterns, until pivoting is comfortable. At this point, sport-specific exercises and drills are added and advanced until the athlete is ready to return to the sport. Return to play is allowed when sport-specific agility testing is performed comfortably. People with grade 1 and 2 injuries usually return to play within 2-3 weeks. People with grade 3 injuries frequently require 6 or more weeks before a return to play.
After sufficient healing of the ligament has occurred, the initial focus of rehabilitation is to restore full ROM. After acceptable knee ROM is restored, the therapist is to concentrate on controlled strengthening. Often in the knee, the functional strength of the quadriceps muscle, especially the medial VMO muscle, is weak and atrophied. After restoration of sufficient strength, the athlete needs to go through sport-specific or function-based training. Upon achieving full strength and pain-free ROM in the lower extremity, the athlete can be cleared to return to their sport, most often without any brace or external support.
Medical Issues/Complications
Persistent instability and laxity may require surgical treatment.
Surgical Intervention
The consensus is that isolated MCL tears rarely require operative repair, while treatment of severe combined ruptures of the MCL and ACL or PCL would require reconstruction. A recent study found that nonoperative and operative treatments of medial collateral ligament injuries lead to equally good results. Another indication for surgical intervention would be persistent instability and consist of tissue repair and imbrication. Often, reinforcement with an allograft is necessary.
Recovery Phase
Rehabilitation Program
Physical Therapy
Long-term outcome studies have shown that almost all patients with grade 1 and 2 injuries have returned to full preinjury activities by 3 months. Isolated grade 3 injuries still allow excellent return to preactivity levels by 6-9 months.
Medication
The goals of pharmacotherapy are to reduce morbidity and to prevent complications.
Nonsteroidal anti-inflammatory drugs
Have analgesic, anti-inflammatory, and antipyretic activities. Their mechanism of action is not known, but they may inhibit cyclooxygenase activity and prostaglandin synthesis. Other mechanisms may exist as well, such as inhibition of leukotriene synthesis, lysosomal enzyme release, lipoxygenase activity, neutrophil aggregation, and various cell membrane functions.
Ibuprofen (Ibuprin, Motrin)
DOC for patients with mild to moderate pain. Inhibits inflammatory reactions and pain by decreasing prostaglandin synthesis.
Adult
200-400 mg PO q4-6h while symptoms persist; not to exceed 3.2 g/d
Pediatric
<6 years: Not established
6 months to 12 years: 4-10 mg/kg/dose PO tid/qid
>12 years: Administer as in adults
Coadministration with aspirin increases risk of inducing serious NSAID-related adverse effects; probenecid may increase concentrations and, possibly, toxicity of NSAIDs; may decrease effect of hydralazine, captopril, and beta-blockers; may decrease diuretic effects of furosemide and thiazides; may increase PT when taking anticoagulants (instruct patients to watch for signs of bleeding); may increase risk of methotrexate toxicity; phenytoin levels may be increased when administered concurrently
Documented hypersensitivity; peptic ulcer disease; recent GI bleeding or perforation; renal insufficiency; high risk of bleeding
Pregnancy
B - Usually safe but benefits must outweigh the risks.
Precautions
Category D in third trimester of pregnancy; caution in congestive heart failure, hypertension, and decreased renal and hepatic function; caution in coagulation abnormalities or during anticoagulant therapy
Naproxen (Anaprox, Naprosyn, Naprelan, Aleve)
For relief of mild to moderate pain; inhibits inflammatory reactions and pain by decreasing activity of cyclooxygenase, which results in a decrease of prostaglandin synthesis.
Adult
500 mg PO followed by 250 mg q6-8h; not to exceed 1.25 g/d
Pediatric
<2 years: Not established
>2 years: 2.5 mg/kg/dose PO; not to exceed 10 mg/kg/d
Coadministration with aspirin increases risk of inducing serious NSAID-related adverse effects; probenecid may increase concentrations and, possibly, toxicity of NSAIDs; may decrease effect of hydralazine, captopril, and beta-blockers; may decrease diuretic effects of furosemide and thiazides; may increase PT when taking anticoagulants (instruct patients to watch for signs of bleeding); may increase risk of methotrexate toxicity; phenytoin levels may be increased when administered concurrently

Pregnancy
B - Usually safe but benefits must outweigh the risks.
Precautions
Category D in third trimester of pregnancy; acute renal insufficiency, interstitial nephritis, hyperkalemia, hyponatremia, and renal papillary necrosis may occur; patients with preexisting renal disease or compromised renal perfusion risk acute renal failure; leukopenia occurs rarely, is transient, and usually returns to normal during therapy; persistent leukopenia, granulocytopenia, or thrombocytopenia warrants further evaluation and may require discontinuation of drug
Ketoprofen (Orudis, Oruvail, Actron)
For relief of mild to moderate pain and inflammation.
Small dosages are initially indicated in small and elderly patients and in those with renal or liver disease.
Doses >75 mg do not increase therapeutic effects. Administer high doses with caution and closely observe patient for response.

Pediatric
<3 months: Not established
3 months to 12 years: 0.1-1 mg/kg PO q6-8h
>12 years: Administer as in adults
Coadministration with aspirin increases risk of inducing serious NSAID-related adverse effects; probenecid may increase concentrations and, possibly, toxicity of NSAIDs; may decrease effect of hydralazine, captopril, and beta-blockers; may decrease diuretic effects of furosemide and thiazides; may increase PT when taking anticoagulants (instruct patients to watch for signs of bleeding); may increase risk of methotrexate toxicity; phenytoin levels may be increased when administered concurrently
